Generally, for most single cam engines, there is a dot or mark on the cam sprocket and a similar mark on the crank sprocket. Point them at each other. the timing marks on the crank and cam sprockets must be lined up with marks on the timing chain in an overhead cam engine

The timing marks on a 1969 Ford 360 should line up between the timing chain and the cam sprocket. This sets the initial timing which can later be adjusted using a timing light.

ON MY 2.2 4CYLINDER ( 1999 ) YOU HAVE TO PULL THE TIMING CHAIN COVER TO SEE THE " TIMING MARKS " . ON THE CRANK SPROCKET IT IS A PUNCH MARK.....ON THE CAM SPROCKET IT IS A SMALL HOLE IN THE SPROCKET . BOTH MUST LINE UP WITH TABS ON THE CHAIN TENSIONER. THE REST OF THE TIMING IS DONE BY CRANK & CAM SENSORS AND THE COMPUTER.

There are marks on the chain that coordinate with marks on the timing gear. Make sure these line up when putting on the timing chain, and you should be good to go. Getting to the timing chain is the real battle.

1. Before beginning any disassembly procedures, position the No. 1 piston at TDC on the compression stroke.2. Disconnect the negative battery cable.3. Remove the timing chain cover (place a suitable drain pan under cover assembly).4. Remove the cylinder head cover.5. With the No. 1 piston at TDC, the timing marks on the camshaft sprocket and the timing chain should be visible. Mark both of them with paint. Also mark the relationship of the camshaft sprocket to the camshaft. There are three sets of timing marks and locating holes in the sprocket; they are for making adjustments to compensate for timing chain stretch.6. With the timing marks on the camshaft sprocket clearly indicated, locate and label (for easier reference) the timing marks on the crankshaft sprocket. Also label the chain timing mark. Of course, if the chain is not to be reused, marking it is useless.7. Unbolt and remove the sprocket, along with the chain. As you remove the chain, hold it where the chain tensioner contacts it. When the chain is removed, the tensioner is going to come apart. Hold on to it and you won't lose any of the parts. The crankshaft sprocket can be removed with a puller, if necessary. There is no need to remove the chain guide unless it is being replaced.To install:1. Install the timing chain and camshaft sprocket together after first positioning the chain over the crankshaft sprocket. Position the sprocket so that the marks made previously line up. (This is assuming that the engine has not been disturbed.) The camshaft and crankshaft keys should both be pointing upward. If a new chain and/or gear is being installed, position the sprocket so that the timing marks on the chain align with the marks on the sprocket (with both keys pointing up). The marks are on the right-hand side of the sprockets as you face the engine.Note: The Z24i and KA24E engines do not use the pin counting method for finding correct valve timing. Instead, set the timing chain by aligning its mating marks with those of the crankshaft sprocket and camshaft sprocket. The camshaft sprocket should be installed by fitting the knock pin of the camshaft into its No. 2 hole. On the Z24i engine, the No. 2 timing mark must also be used.2. Install the camshaft sprocket bolt and tighten it to 87-116 ft. lbs. (118-157 Nm).3. Install the chain guide and tensioner. Adjust the protrusion of the chain tensioner spindle to zero clearance. Tighten the bolts to 4-7 ft. lbs. (6-10 Nm).4. With a new seal installed in the timing chain cover and a light coat of oil applied to the seal, install the cover.5. Install the cylinder head cover.6. Connect the negative battery.7. Check all fluids and add, as necessary.8. Start the engine and check for any leaks. Check the ignition timing and adjust, as necessary.

It has two chains. CAUTION: At no time, when the timing chain(s) are removed and the cylinder heads are installed, may the crankshaft and/or camshafts be rotated. Failure to follow these directions will result in valve and/or piston damage. NOTE: Because this is not a free-wheeling engine, and it jumps time, there will be damage to the valves and/or pistons and will require the removal of the cylinder heads. The camshaft sprockets should only be disassembled from the camshafts when one of the components is to be replaced. Remove Valve Covers, Oil Pan and Engine Front Cover. Remove crankshaft position sensor pulse wheel. Rotate engine to No. 1 top dead center (TDC). Remove two bolts retaining RH timing chain tensioner to cylinder head and remove timing chain tensioner. Remove RH timing chain tensioner arm. Remove two bolts retaining RH timing chain guide to cylinder head and remove timing chain guide. Remove RH timing chain from camshaft sprocket and crankshaft sprocket. Remove two bolts retaining LH timing chain tensioner to cylinder head and remove timing chain tensioner. Remove LH timing chain tensioner arm. Remove two bolts retaining LH timing chain guide to cylinder head and remove timing chain guide. Remove LH timing chain from camshaft sprocket and crankshaft sprocket. CAUTION: Do not rotate crankshaft and/or camshafts or possible engine damage may occur. Inspect the plastic running face on timing chain tensioner arms and timing chain guides. If worn or damaged, remove and clean oil pan and oil pump screen cover and tube. Installation NOTE: If engine has jumped time, make sure that all repairs to engine components and/or valve train have been made. Then rotate engine counterclockwise 45 degrees. This will position all pistons below top of deck face. Install Cylinder Heads as outlined. Locate the copper links on the timing chains. They will be 180 degrees apart fro one another on each chain. When installing the chains on the gears, line one copper link on the chain with the alignment mark on the crank gear, and line up the other copper link on chain with the cam gear mark on each respective side of the engine. On the crank gear, both chains line up to the same mark. Install timing chain guides . Install timing chain guide retaining bolts. Tighten to 8-12 Nm (71-106 lb-in). NOTE: Crankshaft sprockets are identical. They may only be installed one way. Install LH timing chain on camshaft sprocket. Make sure copper link of timing chain lines up with timing mark of camshaft sprocket. Install LH timing chain on crankshaft sprocket. Make sure copper link of timing chain lines up with timing mark of crankshaft sprocket. Install RH timing chain on camshaft sprocket. Make sure copper link of timing chain lines up with timing mark of camshaft sprocket. Install RH and LH timing chain tensioner and secure with two bolts on each. Tighten bolts to 20-30 Nm (15-22 lb-ft). Lubricate timing chain tensioner arm contact surfaces with clean engine oil, and install RH and LH timing chain tensioner arms on their dowels. With a suitable C-clamp around the timing chain tensioner arm and timing chain guide, remove all slack from timing chain while using caution not to bend the timing chain guide. Remove lock pins from timing chain tensioners and make sure all timing marks are aligned. Install Engine Front Cover, Oil Pan and Valve Covers. Start engine and check for leaks and proper operation.

Line crank shaft pulley timing mark on tc mark on timing belt cover. Look at cam shaft timing belt sprocket and locate the small triangle (not diamond shape) located on the plate attached to the timing sprocket. Referencing the timing sprocket look approximately at 5:00 o'clock under the timing sprocket and locate the other small triangle. Line these 2 marks up. Put timing belt on. Make sure the cam shaft sprocket and crank shaft sprocket do not turn while installing the belt. The crank shaft pulley must be removed in order to get the timing belt on.

You must line up the TDC marks on the cam sprocket and the crankshaft gear with the light colored links on the new timing chain. Check a Clymer or Haynes manual for specific instructions for the SOHC engine.His daughter says hi.

Crankshaft dot should be at the 5 o'clock position. Intake camshaft sprocket should have the "INT" mark at approx. 2 o'clock. Exhaust camshaft sprocket should have the "EXH" mark at approx. 10 o'clock. Timing chain has 2 silver links and 1 copper link. Copper link aligns with the mark on the Intake cam sprocket, 1 silver link aligns with the mark on the Exhaust cam sprocket, and the other silver link aligns with the mark on the crankshaft sprocket.

A striaght line drawn through the cente line of the camshaft and the crankshaft should line up the cam sprocket time hole (pointing down) the upper and lower marks on the chain damper and the crank sprocket time mark (pointing up). Simple, right?

User Avatar

If you are refering to the timing chain teeth, you want the lower and smaller crank gear to have its punch mark aligned at 12:00. The Keyway on the crankshaft should be at aprox the 2:00 position when the punch mark is at 12:00. The upper cam sprocket punch mark needs to be aligned at the 6:00 position. Doing this will put both punch marks at the closest point to each other. Use a ruler or a good eye to make sure they are in line. Do this with the chain set aside to get everything in line before you add the chain. Then remove the cam sprocket to add the chain. But be carefull not to move the cam as you reinstall the sprocket and chain.

If it is a V8 set the motor at top dead center #1 cylinder a the very top and the cam mark should line up with the middle mark on the crank sprocket or o degrees advanced. it doesnt have a belt, it has a chain. there should be one or two lil dots on the chain and like a very small like on the sprocket, make the dots on the chain line up exact with the sprocket and your good There is one mark (dot) on your came sprocket and one mark (dot) on your crank sprocket right about your crank "key" slot. Align those two marks (cam sprocket mark down, crank sprocket mark up). Now turn your crank 2 complete revolutions and verify that those two marks are in the same location that you originally set them. Obviously you will have to have the chain on. I just installed my millionth and one yesterday.

you take out the peep plug on the top of the flywheel cover look in on the flywheel there are marks a t and a f line up the t take off the cam sprocket take a small screwdriver and keep sliding the chain around the sprocket until the mark on the sprocket lines up with the mark above it on the head then turn it over until the holes line back up make shure your cdi lines up to make shure you are on the right stroke.

The timing chain on the SOHC motor is easy to set. First, before you remove the chain, rotate the crankshaft 90 degrees clockwise past TDC (top Dead Center) This lowers the pistons to the middle of the cylinder block so you don't damage any of the valves in the head. Proceed to remove the timing chain. When installing the new timing chain, rotate the camshaft so the mark on the cam gear is at the 12 0'clock position. You can use a 3/16 drill bit to line up the camshaft sprocket with the locating hole in the cylinder head to be sure the gear is in the correct position. Rotate the Crankshaft Counter-Clockwise back to TDC so the mark on the crank sprocket matches the timing mark cast into the block, be sure when installing the chain, all the slack of the chain in on the tensioner side.

Take off the chain and then there should be 2 little bolts holding on the sprocket. Remove those and then rotate the sprocket slightly so its teeth line up with the teeth on the output shaft and it will slide right off.

The timing mark is a line that goes across the harmonic balancer that should line up with the mark on the timing chain cover. It is on the drivers side on the bottom of the timing cover.
