Which is better timing chain or timing gears?
A gear driven system will always be much more stable, accurate, and last longer than any belt or timing chain, even a double-timing chain setup. The disadvantage to it is that they are typically noisy, require more lubrication than other methods and adds more overall costs to other motors designed without it.
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.
Why are timing chains used instead of gears?
Even many engines where the camshaft is located in the block have gone to timing chains rather than gears mostly because they are quieter and cheaper to manufacture. However, the term timing gear has hung on and is still in common use to describe the sprockets that drive timing chains and timing belts as well.
When to replace timing belt and gear set?
Don’t take a chance reusing an old timing belt, chain or gear set. A high mileage timing chain that has stretched and is loose can’t maintain accurate valve timing and should be replaced if play exceeds specifications. The camshaft and crankshaft sprockets should also be replaced along with chain.
Where does the timing chain go on a pushrod engine?
As a rule, most pushrod engines use a timing chain to drive the camshaft, though some older four and six cylinder engines use a gear set. A short chain or gear set works well in this kind of application because the camshaft is located in the block just above the crankshaft.
