Tensioner arm question

[nicknorth11]

I bought my car after someone had tampered with the tensioner arm and it didn't have any washers or anything between the bolt that holds it on and the arm itself, thus pinching the arm against the block. I put a washer in there to give it some space, but the arm still gets stuck. Does anyone know what type of washer/bolt/etc. goes there?

Thanks

Lets start with the part numbers, according to CAPS:

MN119896 - Tensioner arm
MF241251 - bolt
MD129421 - washer

Make sure you have the correct tensioner arm. I put a light coating of assembly lube or white grease on the tensioner arm shaft and inside the tensioner. Slide the tensioner on. I also put a light coating of lube on the outside of the tensioner where the washer will make contact. With the above washer against the tensioner, torque the bolt to spec. Do not put a washer behind the tensioner. Also, don't use any old washer that seems to fit. The washer you tried may be weaker and could be bending, causing the pinching. If you still have a problem with it pinching, I would suspect you may have the wrong or damaged tensioner or you have overtightened the bolt.

I just ordered the washer and bolt that you mentioned. Also, I will install as you mentioned. Thank you.

Does anyone happen to know the torque spec. for that bolt?

Factory manual on CD. A must when rebuilding these engines. Forced performance sells them for $35 or you can usually find them on e-bay for around $5 - $10.

You should be able to find a PDF version of the manual on the web. Just do a search on this site.
