Remove the tensioner spring from the pocket in the front timing belt upper cover and install it in the slot in the tensioner lever and over the stud in the crankcase. Push the tensioner lever toward the water pump as far as it will travel and tighten the lockbolt snug. Install the timing belt. Adjust the timing belt tension Set it up same as a stock cam timing. The Cam turns at 1/2 the speed of the crank..the timing chain link count is an even number to assure it does not change timing...odd number chain link count would add or subtract a degree or so with each revolution First know exactly what engine you are looking at - refer to type markings stamped on the block and the logbook for the vehicle. Then look it up on the internet. If it's an 'interference' engine, chances are high that you have substantially damage.. So, if you simply set the crankshaft to TDC without looking at the position of the camshaft, you may actually be at TDC on the exhaust stroke for cylinder #1. So, after you get the crankshaft (by flywheel indication or by checking actual piston location), check the camshaft sprocket to make sure the camshaft alignment mark is at the TDC.
1. Remove all spark plugs so that the crank shaft could be rotated easily. 2. Rotate the crankshaft to align the timing mark of the crankshaft gear with the index mark on the engine cover. 3.Rotate the crankshaft +/- 30 degrees to ensure that the valve could not hit the pistons when aligning the camshaft gears. 4 Place special tool 11 9 462 on exhaust camshaft and check timing. Note: The timing is correctly adjusted when special tool 11 9 462 rests flat on the cylinder head or protrudes by up to 0.5 mm to the exhaust side. Remove all special tools The following instructions begin after the timing cover and old timing set have been removed. Installing the timing set and degreeing the camshaft will be easier if you loosen the rocker arms so that the camshaft can turn freely. You should be able to turn the camshaft by hand. Make sure that the engine mounting surfaces and your new timing set.
If the crank sensor is set up such that the 10th tooth after the missing teeth is at TDC, position the cam sensor such that it is between 110 -250 degrees before TDC on cylinder #1. This will create a proper position. This cam sync input can be configured as a magnetic or hall effect (digital rising or digital falling) input in the software The crank gear is in place with a key and when timing to the cam your marks should be around 1:30-2 o'clock area. And 1/6 should be up top. Valves are the key. You can always use a few pushrods to run down on the followers and visualize how that cam will have to work according to firing order at tdc comp on 1 and tdc exhaust on 1 which will be. Spin the crankshaft until the dial indicator is on the cam lobe's base circle. That is the area on the back side of the lobe that provides zero lift. When you know the dial indicator is on the base circle, zero out your gauge. Now, spin the crank and keep an eye on the indicator This position is important when installing a new camshaft, because the cam must be set with the crankshaft at TDC. If the camshaft is off by a tooth, the engine will lack power and risks damage to the piston and valves. STEP 1: Align Flywheel Timing Mark and Inde
With the crank gear at 12:00 and the cam gear at 6:00 after you have installed the timing set,... all you need to do is turn the crank one full revolution, which will put the cam gear at 12:00 and crank gear back at 12:00(and the engine at TDC firing #1 cylinder) and you can then install the distributor just as you have outlined Yes it is correct, don't confuse camshaft timing with ignition timing. The camshaft turns half of what the crankshaft turns in a revolution. In other words, if you start with the marks aligned as in the photo and turn the crankshaft 1 revolution the mark on the cam will be 180 degrees from the mark on the crankshaft gear After you have installed your crankshaft and camshaft and connected the two with your timing set, take a moment to make sure you have your cam installed straight up, which means the tick marks. you will need to pull the crank damper, and the oil pump Point the two arrows on the lower gear straight down, line the two gold links onto the arrows then point the arrow on the cam at the gold link up top then put the guides and tensioner on tight. If you dont feel comfortable with any of these directions, take it to a shop
. Remember: The camshaft angle is half of the crankshaft angle, therefore the camshaft will correspondingly advance or retard by ± 2°. By changing the cam timing, enhancements to the camshaft characteristics can be achieved The easiest is by repositioning the crank gear of an adjustable timing chain set. Or you can drill the cam gear's dowel-pin hole and install offset bushings to adjust cam position

Bar the crankshaft over to Top Dead Center (TDC) cylinder no. 1 and lock with TDC locking pin through th The crank gear will most likely have the cut out in back of the gear that will look like a V if one cut out that lines with the pump. If two cut outs then pump lines in between both. If you lost the cam and crank timing from a broken belt then stop what your doing and pull the head to replace some bent valves The timing is achieved by placing the desired keyway over the crank key and aligning the corresponding timing mark with the timing mark on the cam sprocket. For GM and Chrysler applications, refer to Figure 1 below: To advance the camshaft 1°, place the 2A keyway over the crank key and align the 2A timing mark with the mark on the cam sprocket Slip the bearing end of the camshaft gear into the bearing hole. The camshaft gear will have the round indentation stamp on the end of the gear. Rotate both the camshaft gear and the crankshaft simultaneously to align the two timing marks. This process may take several attempts to fit the gears together and properly align the timing marks
Camshaft to crankshaft: the timing marks on crank gear and cam gear have to align. If they don't, then the next step is irrelevant. Oil pump to camshaft: the oil pump gear needs to mate with the cam gear in a position such that the distributor shaft will engage it so that the rotor is pointing to the normal #1 position on the distributor cap. Posted: Sun Dec 28, 2014 1:02 pm Post subject: Re: how to set camshaft with crankshaft gears for timing: Maybe this will help--info from someone else I had tucked away on my 'puter.. Timing without timing marks. Unfortunately, you will have to remove your cylinder head to verify #4-valves rock-over. (both are open) Then remove your camshaft gear and roll your crankshaft for #1-TDC
Once the timing belt was in place, with both dots aligned (cam gear dot at 6 o'clock and crank gear dot at 12 o'clock) and with the cam adjuster marks set at zero, I tightened the cam gear's center left-hand-thread bolt to 70 ft-lbs (I needed a 12-point, 5/8-inch socket for this bolt) THE cam gear rotates exactly once for each two times the crank rotates,the cam gear lines up at the 12 oclock crank and 6 oclock cam gear orientation when the #6 cylinders on the compression stroke, rotate the engine one complete revolution and the cranks again at 12 oclock but the cam gears index mark is now at 12 oclock, indicating the #1. Now we're ready to fire the engine. Assuming the engine starts, make sure the engine is idling at proper idle speed and not on the fast-idle cam of the choke. It's important that the engine be idling at its warm-idle rpm. It's likely that our static ignition timing at the crankshaft at idle may not be the desired 10 degrees BTDC
Which means to align the crank timing marks and the cam timing marks to spec, then re-install the timing chain. Before moving the cam or crank, find a copy of the manufacturer's procedure on how to do this without banging the valves into the piston or the valves into the valves Apr 22, 2015. #1. Working on a 96 G16 Yamaha Gas golf cart. Can anyone post the timing procedure for re timing the crank, cam and balancer. I can see timing marks but not sure were there supposed to be when at TDC. Thank You Also, put a light coating of anti-seize on the cam hub and crank hub. This will aid assembly and permit removal if you need to pull the assembly apart to advance or retard the cam.[I used a true roller timing set. with 3 key ways; the sprocket was installed on all three to verify the accuracy of the set. It proved to be accurate on all keyways (Image/Jeff Smith) Regardless of whether the cam is a flat tappet or a roller, cam timing cards will deliver a all of the important information. While the actual specs may change, the relationships such as valve lift, duration, intake center line, and lobe separation angle all remain the same from flat tappet to mechanical roller
Crankshaft timing marks: The crankshaft has a pressed on timing gear. This gear has a small dimple punched on one of the teeth on this gear. This dimple is a timing mark. With the crankpin at top dead center, the timing mark should be in the 2â€ 30 position. The camshaft has an aligning mark in line with the timing hole on the camshaft gear The marks on the right side outer case's crankshaft hole and internal gear, as well as the cam sprocket and and cam tower assembly should both align when the cam timing is properly set (site each of the pairs of marks with your eyes level to the marks) Ignoring the outer and offset o icon on the crank gear, we set the chain up so the dot on the cam gear aligned with the o keyway. Measuring intake centerline with the early timing chain set indexed in this position yielded a 105 degree reading. That placed us within 1 degree of the cam card spec, a satisfactory reading despite th
Crankshaft sensor alignment tool - 303-1521. TDC Timing peg 303-507. Begin by preparing the vehicle. Place transmission in Neutral. Raise and support the front of the vehicle safely. Remove the right front wheel well liner. Rotate crankshaft until cylinder 1 is 45 degrees BTDC. Use the alignment holes on timing cover and crankshaft pulley You can see in the photo above the Timing Marks. The Flywheel above is current set for TDC on Front Cylinder. Below is the inside of the Clutch Cover (Right Hand Side) and the cogs at the Front of the engine are the Crank and Camshaft Chain-Drive.

I have done a replacement of the timing belt at 100 000 mark with a chrysler dealer. It has been misfiring for a while since. I brought it to a dealer who told me that the camshaft crankshaft and oxygen sensors.
Set Conditions P0016 code, t he difference between the Bank 1 exhaust camshaft position and the crankshaft postion is more than 10.0 degrees. If the vehicle is equipped with the stop/start feature, the system will be disabled when this DTC is active. Incorrect engine oil viscosity or oil filter. Engine oil aerated or contaminated . The factory keyway is the rounded one (2:00 o'clock position); 2 degrees advanced is at 10:00 (there's a slight peak to the top of the keyway); 2 degrees retarded is the squared-off one at about 5:30 Aaron, why don't you just spot check your cam timing?, to which I responded Huh?. Just measure how much lift you have at overlap and compare it to the spec! Too freakin simple. So since then, whenever a set of cam marks leaves me wondering if it's right, I make some very quick and simple measurements to check my work The camshaft is connected via the timing chain and sprockets at a 1:2 ratio to the crankshaft and therefore revolves once for every two turns of the crank. Its purpose is to operate the intake and exhaust valves in the correct timing with the piston as it sequences thru the four strokes Then and only then can you turn the camshaft to get it into timing position. After the cam is set, you can bring the number one piston up to TDC by turning the crank. If you don't have a lot of experience working with overhead camshaft engines, it's easy to get into trouble working on the timing chain
2) look through the spark plug hole and eyeball it till the proper piston is nearly tdc (you may be off a few degrees but at this point some marking on the crank should be pointing up, typically a dot on the timing cog) 3) set the crank so piston one is full compression stroke (or between exhaust and intake strokes) set the cam to this position. Now push the bottom sprocket back onto the crankshaft key and re-fit the top sprocket to the camshaft with the two dots aligned again, you may need to rotate the camshaft slightly to get the top sprocket onto the camshaft key. 8) You have now returned to stage 1 of the camshaft timing process. Run through stages 1 to 5 once more
To remove the left timing chain, rotate the crank clockwise 600° (1-2/3rds turn) until the keyway is again at the 11 o'clock position. This will position the left cylinder head cams in the neutral position. This time, the timing mark on the intake cam should be pointing to the left when viewed from the front, and the mark on the exhaust cam. set cam to 12:00 position via locating pin. Set crank shaft to 6 o'clock via dot on lower gear. Verified that crank shaft notch is close to the 2 o'clock position on oil pump. Installed timing gear with phasher and lower gear at the same time. Note: cam phaser has a limiter installed Loosen crank bolt and cam gear bolts. (if you are not sure about installing those diamond coated washers, then you'll have to teardown the crank gears etc and check) Install the cam timing bar across the back of the cams; With the timing tools in place, make sure you have the timing chain tensioner released and holding tension on the chain The cam has a dot of white paint over the timing dot as well. There was not a pressed in dot on any of the crank teeth, and if there was a paint dot, it is long gone. The crank has what looks like small insert grooves in the shaft itself. Hoping that someone out there could take a pic of the crank for an xt6.75 that still has the timing mark on it
Take the crank pulley off and the timing cover. With 2 people, set the chain with the two gold links in between the crank dot. Put an adjustable wrench on each cam. Put the chain on the intake cam dot and youll have to turn the exhaust cam clockwise and the intake cam counter clockwise a small amount to get the gold link on the chain to set on. If you turn the engine over with the timing cover off but timing chain on, you'll notice the small crank gear spins twice as fast as the large cam gear. #1 tdc occurs after the compression and exhaust strokes, and timing is set after the compression stroke; you're sitting at the exhaust stroke, so the cam timing is 180° out when compared to. To set the timing chain, follow this procedure. To set the camshaft, first of all, set the tappet clearance on number 8 valve (the valve at the back of the engine closest to the steering wheel) to 0.023in (when the cam and rocker is in its lowest position). Then set number 7 valve to 0.025in. Turn the engine away from TDC Install the crankshaft timing gear. (T) With the crankshaft key groove facing upward, install the crankshaft timing gear into the crankshaft. j r \ When doing this, the matchmarks of the oil pump drive shaft gear and crankshaft timing gear should be matched at 1. Using SST and a hammer, tap in the timing gear. 09223-0001 03 is an ALH, where the injection timing is set by adjusting the pump pulley in very small increments, as measured in the TDI timing function in basic settings. 04 through 06 are PD and the timing is adjusted in a similar manner with the cam pulley, but as above, you are measuring KW and the optimal setting is a matter of much debate
facts are you had it running once so must of got timing correct or fairly close, you never done up the crankshaft bolt enough ie the main issue ie when engine rev'd it rotated on crankshaft and done the valves, i would also check the vac pump on exhaust cam shaft has not failed on the bearing and is stopping the exhaust camshaft or creating to.

This will place the cam gear with the mark facing straight up. Index the pump gear so its marks match and install the pump. Basically no matter how you do it as long as the cam gear mark is at 12 Oclock and the IP gear marks match it will work
The keyway on that crank WILL be at 12 oclock when the #1 cylinder is at TDC. Theres no other possibility because all the cranks have the keys cut in the same spot. So get a good timing set, crank key at 12oclock, crank gear will have a dot at 6oclock. Cam gear will have dot at 12oclock. Dot on cam gear will line up with mark on front rockerarm.

Ships from Land Rover Palm Beach Parts, West Palm Beach F Since the camshaft turns at 1/2 the rate of the crankshaft, I carefully set the engine at TDC so what I think is the timing mark on the camshaft is at the 12:00 position. The timing mark is faint and I put some white paint on it This also caused the timing belt to break. I replaced the water pump and put a timing belt on it. I only have compression in two cylinders and it won't start. I followed the instructions for installing the timing belt from the book. I think they may be wrong. What I need to know is how exactly to set the crank and cam before I install the.
included. Next align the camshaft and crankshaft timing marks and loop the chain around the crankshaft sprocket and install over the camshaft timing pin. Loosely install the camshaft bolt(s) to hold the camshaft sprocket in place. 11. If using a Hex-A-Just style timing chain set now is the time to adjust the camshaft timing 1. The first step is to install your new camshaft and line up the stock timing marks. 2 To begin the actual degreeing procedure, the degree wheel should be attached to the front of the crankshaft. A pointer of some type such as a piece of wire should be secured to the front of the engine. The engine should be capable of turning in either direction More often, cam timing errors are different between the intake and exhaust cams. One cam may be advanced more than the other; one cam might be retarded more than the other; or one cam might be advanced while the other retarded. These differences result in a change to the lobe separation angle
Timing is set at tdc and the chain tensioner thrust pin reinstalled into its housing on the first notch then torqued. Problem I'm getting is after a few hand rotations, timing is always out. If at tdc crank, the cam dowels are approx 8 degress out. If I jump the chain forward a tooth, its about 8 degress btdc All of this sets the cam gears to neutral and prevents the belt from bunching up in the center during VCT operation. 8. Now you can put it back together. If you haven't already done so, remove the cam locking tool. Rotate the crank with the crank bolt one full turn to make sure the belt isn't going to bind on anything Recheck the cam timing, the crank pulley should be on the TDC mark and the cam lobes, sprockets and chain should look like the dia-gram in step 9. 12. Using a feeler gauge set, measure the follower to cam (lash) clearance of each cam lobe. Cold valve lash should be between .010-.013 inch (.254 m.m.- .33 mm). The new cams are ground t
Nov 14, 2011. Most aftermarket timing chain set suppliers include offset crank sprockets that have multiple keyways (usually 3 but up to 9 on some sprockets) machined into the ID to allow this type of adjustability. Cam timing plays a huge role in an engine's power curve. Advancing cam timing shifts the power curve more toward the lower rpm. I tried the cam ahead and behind a tooth to try and get it perfect and make sure it was timed correctly. My cousin was holding the 17mm nut on the crank with a rachet to try and keep piston at TDC with flywheel mark lined up. The timing mark slips off if you don't hold the crank like that
There's a dowel pin on the cam and the crank has a keyway. If the dots are lined up you can't screw it up. Then get your #1 piston on TDC compression stroke (your timing mark on the crank should be close to zero). Drop the distributor in and the rotor should be pointing slightly before the #1 position (it rotates clockwise) Symptoms of Being 1-Tooth Off on Cam Timing - posted in Advanced Virtual Mechanic: We were having some discussions around the shop regarding what the symtoms would be if you were 1-tooth off on cam timing in either direction (with a stock cam). Obviously, the car would be weak whether it's advanced or retarded a tooth, but for those who have been there before, what did you see.I have a spare.
Joined Nov 30, 2009. ·. 29 Posts. #3 · 16 d ago. If the cam dot and crank dot on the timing set are opposite each other then you are good. Sounds like maybe the distributor is installed in the wrong spot. I would confirm that you are indeed at TDC and not 180* off from that and re-install the distributor 13. Set the ignition timing to factory spec. and lock the dis-tributor. If the distributor position after setting the timing, is not in the center, you probably have the cam timing one tooth off (see illustration). 14. Break-in should consist of 10-15 minutes of 1500 - 2000 RPM and 50 -100 miles of varied RPM below 4000 RPM On Multi Cylinder, Twin Cam, engines the assembly drill is a bit different. Both intake and exhaust cams must be timed right. Again, set the number one piston at TDC on the compression stroke. Now position each cam so the timing marks Match. The intake cam will usually have a IN stamped on it and the exhaust cam will have an EX. Don't get. 13,479 Posts. #2 · Aug 13, 2016. Just set the crankshaft timing belt drive pulley to top dead center and then set each cam pulley to TDC. It sometimes helps to remove the spark plugs to make the crank easier to move. The cam pulleys can be tricky as sometimes they like to move on you due to spring tension on the camshaft
