Does anyone know the factory torque specs for the different bolts on the balance shaft cover? They are different sizes, so I'm hesitant to just slam them back in, without the specs. Thanks in advance!

The problem with Clark's is that none of them show the same balance shaft cover as the one on my 87 951.

ehall

but also, thank you for the link.

Paulyy

Which one do you have? IICR there's only 2

the one with the bearing and the one with out the bearing.

ehall

mine has the bearing, but the bolt pattern is different from either pic.

Paulyy

These are the only ones i know off.

The pic on the bottom is the correct diagram for my Upper balance shaft cover. I didn't look at the lowers, before. This pic is just the mirror image. I post a pic of mine later. It didn't match either of the Upper diagrams. I had one of the M6 x 58 bolts crack in half. Luckily, when I pulled the cover, I was able to twist it out with just my fingers. I was imagining a nightmare.

Woah how did that break! over torqued?

Same balance shaft housing i have.

Not sure, but inspecting the bolt, it snapped right at the top of the threads. It was HARD to break free! Perhaps someone used Mega lock-tite? I figured that if it was so hard to break loose, I would surely be in for a terrible time removing the bit remaining. Luckily, I could turn it right out with my fingers. Very odd, and the bolt thread size is even worse. M6X58 is just a stupid size. Would it really have been so hard for Porsche to use M6x60? lol I'll be adding a washer, needless to say.

Paulyy

There shouldn't be any loctite on the bolts. The orange one use to seal the covers won't lock the bolts in like that. Some people think they're magicians when working on cars!
A 2-3mm thicker washer will do just fine

I couldn't find the proper lock-tite locally. I picked up some gasket sealant. Do you think that will suffice?

I used regular sealant. Works fine, no leaks

Paulyy

Cannot comment. But i believe it will, as long as it'll hold up to temperature. The loctite is quite thin so theres not much between the surface and the housing. most of it squeezes out. so if it's not very think or apply a thin coat all over the areas, you should be okay.

The stuff I have is good up to 400F.
