Default TB Tensioner help please!!!!

Rebuilding my tensioner, I've bumped into yet another oddity.

Why would I have 29 bi-metal discs it it. The WSM calls for either 35 or 40 total (8 or 7 sets of 5). I figured, maybe I have some strange tensioner. Hey, it's a 78, after all.

My tensioner housing has a part number of 9281055412R stamped on it. What the heck is this? This doesn't come close to matching what's in PET5.

Does anyone have any idea what I have going on?

Thanks.

Some knucklehead was in there ahead of you and didn't re-assemble to spec.

Part numbers n cast parts and ending with R are not listed in PET as they are not parts final number. Nothing strange there.

Yeah, a previous screwup was all I came up with, too. I really didn't think anyone had ever been in here, though. The car has 54,000 miles on it and has never had the TB or water pump replaced. I can't explain why anyone would have gone in as far as the tensioner & screwed it up, without doing the rest of the related work.

It's late and I'm tired, but since the number cast into the tensioner isn't a PET number, how do I determine whether I have a 35 or 40 disc model? Any thoughts?

If it helps, my tensioning roller carrier arm is not the, err... normal type. It does not have a roller at the top.

So ... you don't have the safety of the roller between the inside faces of the belt as it comes off the passenger's cam timing gear??????? Gotta go fix all that Kary.

Your tensioner body is the 78-82 style with no oil bleeders (you fill from the top), so it is the 40 shim type.
