Chain Tensioner Supports and Gears, (B) Chain Wheel Spacer, For Porsche®, 1980 -1989
Late-style 1980-on chain wheel supports add insurance against premature chain tensioner failure. Improved geometry reduces the angularity loading, prolonging tensioner seal life. This also reduces side-loads on the chain wheel support pin, preventing damage to your expensive chain housing. Remember to inspect the cam wheel and chain sprockets, as well as the intermediate shaft gear.
