Presumably you sorted this?
The answer is as follows:
Looking from the RH side of the bike, the LH (inlet) camshaft sprocket has 2 marks "IN" and "EX" on opposite sides of the sprocket. The "IN" mark needs to be on the LH side i.e. at the rear of the bike. For the RH (exhaust) camshaft sprocket, the "EX" mark needs to be on the RH side i.e. at the front of the bike. Both marks need to be flush with the top of the cylinder casing.

Turn the motor over clockwise until the punch mark on the gear lines up with the arrow mark on the side case. Check to be sure that the cam lobes are facing to the rear of the bike, if they are pointing toward the front keep going until they face back and the punch mark aligns up with the mark on the case.ab798e0.jpg

Check the cam gear to make sure the two marks on the gear are level with the surface of the head.

Backfiring through the carb isn't a timing issue unless you're firing at BDC (180 degrees out).
or have bad/missing/cracked piston rings / hole in the piston.
I mean, correct me if I am wrong, but that thing IS a 2 stroke, right?

I can email a PDF of the page in the factory service manual that shows how to time the engine. You will need a timing light. The file has two line art drawings and two photos. I can call tomorrow to get your email address. I can then email you and attach the PDF file. Below is what it looks like. The Fixya system doesn't handle PDF files. Please rate my answer.

Timing the Cam to the Crank

There are several ways to time the cam to the crank. Be sure to check the manual before you install the timing chain or belt.

  • Some timing sprockets are properly timed when the marks face each other.
  • On others, there must be a certain number of chain links between the marks.
  • Sometimes chains have colored links that must be aligned with the marks on the sprockets.
  • Some overhead cams have a mark on the cam gear that lines up with a mark on the cylinder head when the timing mark on the damper is at the TDC mark.
Align the timing marks for the camshaft and crankshaft sprockets before removing the timing belt or chain.

If the old parts are available, carefully compare the new gears or sprockets with the old ones. Check the keyway and timing marks just in case there might have been an error made in manufacturing. Sprockets are sometimes stamped backward. Its much better to find the problem during assembly, rather than waiting until problems show up after reassembly and reinstallation.

Maintaining Valve Timing

During a valve job, it is essential to keep the timing chain or belt in place to maintain correct valve timing. Position the number one cylinder at TDC. Some overhead cam engines use a single long chain for a cam drive. The chain can be wedged against its guides with a tapered block of wood.
the chain tensioner on some ohc engines must be wedged to keep the chain in position during cylinder head removal. courtesy of nissan motors.

Some engines have a lower and upper chain. These engines do not require special attention to wedging the chain. Be sure to look for hidden head bolts and check the repair manual before removing the OHC head.

Engine Timing marks on a 4.0 ford ranger on a 2005


Rotate the engine so that No. 1 cylinder is at TDC on the compression stroke. Check that the timing marks are aligned on the camshaft and crankshaft pulleys. An access plug is provided in the cam belt cover so that the camshaft timing can be checked without removal of the cover or any other parts. Set the crankshaft to TDC by aligning the timing mark on the crank pulley with the TDC mark on the belt cover. Look through the access hole in the belt cover to make sure that the timing mark on the cam drive sprocket is lined up with the pointer on the inner belt cover.

Hi, the crankshaft marks are on the belt pulley and timing cover, so you have to mate it up to see them. The cam sprocket mark goes on the bottom, and aligns with another mark on the timing cover. There is a plug you pull out and hole to look thru to align the cam sprocket/shaft.

How do you set the timming on a 2.3 when your putting the new timming belt on


The IGNITION timing on your Ranger is computer-controlled and is not adjustable.


Should the camshaft drive belt/timing belt jump timing by a tooth or two, the engine could still run; but very poorly. To visually check for correct timing of the crankshaft, auxiliary shaft, and the camshaft follow this procedure:
There is an access plug provided in the cam drive belt cover so that the camshaft timing cam be checked without moving the drive belt cover.
  1. Remove the access plug.
  2. Turn the crankshaft until the timing marks on the crankshaft indicate TDC.
  3. Make sure that the timing mark on the camshaft drive sprocket is aligned with the pointer on the inner belt cover.

Never turn the crankshaft of any of the overhead cam engines in the opposite direction of normal rotation. Backward rotation of the crankshaft may cause the timing belt to slip and alter the timing.

Look through the access hole in the belt cover to make sure that the timing mark on the cam drive sprocket is lined up with the pointer on the inner belt cover.

Always turn the engine in the normal direction of rotation. Backward rotation may cause the timing belt to jump time, due to the arrangement of the belt tensioner.

I have a 2002 pt cruiser with a 2.4 litre motor. I've tried to install the timing belt but it does not line up with the 4 scrib marks. I do not know how to rotate the cams in the right order for the belt...


It is typical to have to stretch the belt a tad as you install--needs to be tight across the cam sprockets and from the right cam to the crank gear. Then the tensioner should take up the slack on the other side. 0996b43f80209592.jpg

0996b43f8020873b.jpg enlarge_icon.gifenlarge_tooltip.gif Fig. Proper timing belt routing

  1. Set the crankshaft sprocket at TDC by aligning the sprocket with the arrow on the oil pump housing.
  2. Set the camshafts timing marks so that the exhaust camshaft sprocket is a 1 / 2 notch below the intake camshaft sprocket.
  3. Install the timing belt by starting at the crankshaft. Go around the water pump sprocket, idler pulley, camshaft sprockets and the tensioner.
  4. Move the exhaust camshaft sprocket counterclockwise to align the marks and to remove any slack.
  5. Insert a 6mm Allen wrench into the tensioner opening on the top plate of the tensioner pulley. Rotate the top plate counterclockwise. The pulley will move against the belt and the tensioner setting notch will start to move clockwise. Continue to move the top plate counterclockwise until the setting notch is aligned with the spring tang. Using the Allen wrench, to prevent the top plate from moving, tighten the tensioner lock bolt to 220 inch lbs. (25 Nm). Make sure the setting notch and spring tang are still aligned after the lock nut is tighten. If not repeat the procedure.
  6. Remove the wrench from the belt tensioner.
    NOTE When repositioning the crankshaft to the TDC position, this must be done during the clockwise rotation movement. If the TDC is missed, rotate a further two full turns until TDC is reached. Do not rotate the crankshaft counterclockwise as this will result in improper tensioner settings.
  7. Rotate the crankshaft two full revolutions and verify that the TDC marks are properly aligned.
  8. Check the spring tang is within the tolerance window, if not repeat the previous two steps.

1987/88 fzr750 cannot see timing mark on crank to set up cam timing can see three lines on crank which to use?


hi,this might help,the way i do any engine is simply,rotate the engine untill no1 cylinder reaches top dead centre,the three marks on the crank will be(normally) 3deg before tdc, then tdc,then 3 deg after tdc.,so no1 to tdc,see whwt the marks line up on(normally the centre of the cdi pickup )then set the camshafts,these are normally marked to run on a level plane with the engine rocker cover,so 1 mark on the front cam normally points to the front of the engine on a level with the roker cover base and the rear cam mark normally points to the rear of the engine with the mark level with the rocker cover base,then you reinstall the cam chain and sprockets,keeping the front of the camchain tight (the rear of the chain will tighten after the tensioner is reinstalled)if you have a workshop manual follow that,as what i have said is general rule of thumb and it may vary slightly to the manual,hope this helps..,.cheers

How do you time it after you change the gasket


I assume you are talking about the cam timing. If so, then you first turn the engine so that the "T" mark on the flywheel lines up with the index mark in the timing hole cover. This places the piston at top dead center (TDC). Now position the camshaft so that the cam lobes are both facing downward. Align the two marks on the cam sprocket with the cylinder head cover gasket surface (making sure the piston is still at TDC). Install the two bolts through the sprocket and screw them into the camshaft. Done.

1997 nissan pathfinder timing off. I replaced water pump(behind timing belt). Timing "gears" got moved (two top ones). I don't know how to make sure everything is lined back up correctly.Any ideas?


The cam sprockets should have marks on them (dimples) that should align with marks on the rear timing cover. There should also be a similar dimple on the crankshaft timing sprocket. These will align with their respective marks when the engine is at TDC. The alignment marks are in the following locations as you look at the front of the engine: RH cam sprocket at approximately 11:00, LH cam sprocket at approx 1:00, Crankshaft timing sprocket at approx 4:00 or 5:00. IF you can't find the marks on the cover, put the marks on the sprockets in those approximate positions and set the belt by using a belt tooth count between the marks. Cam to cam should be 40 teeth between the cam marks. Between the LH sprocket and the crank mark should be 43 teeth. You can check TDC by removing your number 1 cylinder spark plug and carefully inserting a long screwdriver and watching the rise/fall as you hand crank the crankshaft into position (which is much easier with the plugs out)

well not sure exactly why it wont line up use something to turn the crank and cam to appropiate position start sliding crank gear until cam gear is touching then start to push both at same time make sure your crank key and cam pin are bothin place On many OHV pushrod engines, the crankshaft sprocket is installed on the crankshaft nose and the crankshaft is rotated to position piston #1 at TDC. At this point, a mark stamped onto the crankshaft sprocket is pointing directly upward (toward the camshaft).
The camshaft sprocket is then temporarily bolted to the cam and used to rotate the cam until a mark stamped on the cam sprocket is pointing directly downward (toward the crankshaft). The sprocket is then removed from the cam (without allowing the cam to rotate).
The timing chain is looped over the cam gear, the mark on the cam gear is positioned directly downward, and the chain is looped around the crankshaft sprocket. When the cam sprocket is attached to the cam, the timing marks on the crank and cam sprockets should be pointing toward one another.
