Rob ... I'd guess you've probably got a pic of every bolt already

Rob, Thanks a lots. Now I can go into my bucket of odd bolts and figure out what part is or will be loose in the near future. Kidding aside, this really is a nice referance.

Did a search (as evidenced by posting in this thread; BTW, great spreadsheet Rob!), but didn't find:

Correct bolt (and washer?) specs for '78-86 "protective plate" aka "engine undertray" aka "belly pan." Anyone know what is OE correct for this?

Found out the Tq value spreadsheet was messed up for some reason and not printing correctly. Since I cannot edit my original post, I'm adding this one. I've produced a PDF that should solve all formatting issues, but obviously cannot be edited. You should be able to download the original spreadsheet from my Post #46 in the thread.

Anyway here are the PDFs. They each consist of 4 pages - 2 for Ft-Lbs, and the other 2 for Nm.

Old Thread Resurrection (and a great thread, at that):

Been looking for the torque specs for the Starter Mounting Bolts and the lower BH mounting bolts, and I see they are listed at 15 ft-lb and 5 ft-lb respectfully.

I've got an '82 versus a to assume that they would be the same value for the same components and the same bolt spec?

Sorry if this has been answered or I don't know how to read...

Putting a 91 S4 back together...

Why is there a discrepancy between the WSM and the spreadsheet as it applies to the main bearing nuts and bolt torques?

i.g., m12 main bolts(nuts) 22, 41, 55+4 spreadsheet vs 14, 29, 43 +3.6 in the WSM

Am I missing a technical supplement?

awesome job! wish i saw this when i forgot the large head 17mm is really like a 13mm and is an m8 not an, how worried should i be that i tightened that M8 to near 25ftlbs (not the 30 that i had the torque wrench set at... i stopped short as it felt like it was just too much torque for that part. But, it was very solid and didnt feel like it was stipping out or anything.

it is going to be save or will it fracture and blow up ?

Ltoolio- both the starter bolts and the lower bellhousing cover bolts are M8 shafts, should both be 15 ft lbs.

Kevin, the torque values for M12 mains on that spreadsheet are from the 90-93 Tech Specs book and should be correct for a '91 (see below, pp. 20-21). The WSM values (on page 10-03) are for the 4.5L motors, so both are correct, just for different year ranges.

Mark- which 'that' bolt are you talking about?

I have noticed that there are a lot of errors on the N-m tab of the spreadsheet. The ft-lb seem to be ok.
