Cam Chain Wheels--How important is flex and softness?

Cheburashka · Post by **Cheburashka** » Thu Sep 20, 2012 1:18 pm

I checked Bill Silver's engine manual and he says it's important to have a soft, flexible rubber wheel for the cam tensioner. I checked mine, and while the upper wheel is rubbery, the lower wheel at the base of the cylinders is quite hard. What happens when a hardened wheel is used? Is it worthwhile to replace it while the engine is apart? Both wheels are very smooth and show no sign of wear.
