Title: Manual timing chain tensioner
Post by: dawson128 on October 30, 2017, 05:44:19 PM
Hello all!

The PO installed a manual timing chain tensioner on my 91 and it is leaking, not from the gasket, but it seems it's leaking on the threads. It could be dripping from the top onto the adjuster screw I suppose, but either way , I plan on placing a slight amount of RTV on the threads and replacing the gasket.

My question is, with the manual tensioner, how do I know when to stop turning the tensioner bolt?

Thanks

EDIT: I read on an older post to rotate the engine (by the crank bolt near the pickup coil I'm assuming? Correct me if I'm wrong) and screw in the tensioner until you feel it contact the chain, then back it out 1/4 turn. Is this still the preferred method?

From the APE cam chain tensioner website:
INSTRUCTIONS

To set the tensioner adjustment, rotate the engine forward while screwing the tensioner bolt in. When you feel the engine tensioner parts (guide, rollers, etc.) make contact with the moving cam chain, back the tensioner bolt out 1/4 turn and tighten the jam nut. (For the finer pitch thread on the APE Pro Series tensioner it is advised to back the tensioner up 1/2 of a turn.)

DO NOT over-tighten the cam chain, as cam chain giude damage could occur. Be sure jam nut is tight against the tensioner body when complete.
