How do you install a new timing chain?
How do you install a new timing chain?
This may take a couple tries. When you are sure the cam marks are lined up properly and the sprocket and the keyway on the end of the cam are lined up, you can push the sprocket back onto the cam and tighten the bolt back down. 9. Put the rocker arms back and re-install the tensioner if needed.
What does a timing chain do in an engine?
What does a timing chain do? A timing chain synchronizes the rotation of the crankshaft and camshaft (s) ensuring proper timing and allows the engine’s valves to open and close during each cylinder’s firing. The chain is located inside of the engine and needs to be lubricated by the oil in the engine, making oil maintenance important as well.
When to know if your timing chain is bad?
If driving an older vehicle, or one with close to 100,000 miles, it is recommended to look for symptoms of the timing chain going bad or failing. Since the timing chain can go bad and will need to be replaced, it is important to be able to recognize the symptoms and have it repaired before it fails completely.
Can a timing sprocket be replaced at the same time?
Yes, Cloyes recommends that all components of the timing system be replaced at the same time. Using a worn sprocket may result in the chain not meshing with the worn sprocket, which could result in poor engine performance. Cloyes offers a wide range of complete timing chain kits for majority of vehicles on the road today.
How to install the timining chain and gears in Your Big Machine?
Align the seal in the opening and then using a soft mallet tap the seal into place in the timing chain cover, alternating as you go until the seal has fully seated into the cover.
How do you put timing chain on Cam?
Place the timing chain onto the cam gear and then over the crankshaft gear as you slide the lower gear over the keyway and into place. Slide the camshaft gear onto the cam, aligning the hole in the gear with the dowel in the front of the cam.

First, with the worn chain installed I checked the cam timing. Then I installed the new chain and rechecked the timing. In the table below you can see the intake cam timing was retarded by 6.625° and the exhaust by 9.50° when compared to the new cam chain timing values.
Why are there marks on the timing chain?
Observations like this can be used to gauge cam chain wear and to determine when the chain should be replaced. Every engine will have specific marks designed into components to aid in the timing of the engine. These marks can also be used to get an idea of the condition the timing chain is in.
Is there a problem with out spec cam timing?
On stock engines where clearance between the piston and valves is plentiful less precise valve control normally won’t be a problem nor will severely out of spec cam timing.
