Understanding Roller Chain Wear Life The

CHAIN WEAR. A roller chain is a series of connected journal bearings that articulate as they enter and leave the sprockets. This articulation results in wear on the pins and bushings. As material is worn away from these surfaces the roller chain will gradually elongate (Fig. 1). Elongation due to wear is a normal phenomena during drive operation.

Valve Guide Reconditioning - Engine Builder

When used valves are salvaged and the stems are reground, grinding removes the chrome flashing. Chrome prevents the stem from galling when cast iron guides are used, and it helps prevent positive valve seal wear on intake valves. If the chrome is ground off and the valve stem is not replated, it must be used with either a bronze liner or guide.
