Re: [DML] Is there an alternate way to tension AC belt

Hey Steve,

Back when this list was moderated, instead of being allowed to be destroyed by 
the daily ramblings of an ignorant, self-important lunatic desperate for human 
interaction at any cost, we used to answer questions like this.  So here's one 
for old time's sake....

I think you are on the right track with the tap.  Those two threaded holes in 
the timing cover are capped on the inside so the bolts actually never work as an 
oil seal.  You can verify this by removing them and putting a long punch through 
the hole.  But because of this, the length of those M7s is critical.  Make sure 
you mark your depth and don't go too far with the tap.  Just work slowly and 
you'll be fine.  You do not want to break the timing cover or you'll be rather 

To be safe, you'd probably also be better off removing the entire bracket along 
with the blanking plate and o-ring.  Then tape over the cam access hole so you 
don't get anything falling down in the crankcase while you work.  With your new 
bolts, error on the side of shorter rather than longer; there is plenty of 
thread for such a non-critical part.  I always use some anti-seize going back in 
for fear of exactly this scenario.

Good luck,

Jake Kamphoefner

Subject: [DML] Is there an alternate way to tension AC belt

Several months ago I took my AC belt out of the car and the other day
I decided to put it back it. Well, I'm having trouble getting the
thing to tighten because one of the bolts for the bracket will not
stay in the engine. The threads are stripped and I really don't want
to tap the threads since the metal would end up in my engine.

Has anyone ever ran into this, or better yet, is there a better way to
tension the belt rather than use the stock design?

The picture below shows which bolt is completely loose. The top bolt
feels as if its threads are giving way as well. I'm afraid if I
tightening it too much its threads will give way as well.
