Torque specs for IMS, AOS and clutch replacement

[John L]

I'm going to pull the tranny this weekend and the links I had to the various manuals with the torque specs for the job don't seem to be working any more. My plan is to replace all the usual suspects while I'm there but I really need to find the torque numbers before I start. Any help would be greatly appreciated. Thanks

okay, i know search is your friend, found most of the torque specs one at a time in different threads but cant locate the following.

AOS (2) bolt torque to case

Oil Cooler (4) bolts torque to case

tightening sequence for flywheel bolts 19ft.lbs then 90* stretch

tightening sequence for pressure plate bolts 17ft.lbs

thanks for any input

[logray]

aos bolts 7.5 ft lbs

oil cooler 7.5 ft lbs

yes tight seq for flywheel and pplate is good.

thanks logray, your threads and comments are always very helpful and I've spent hours pouring through most of them. Thanks for sharing what you learn and do along the way!

Checking the 996 engine manuals at (link removed)

Seems Engine 1 pdf lists flywheel ft lbs at 67 on page 116.

I recall having to use a breaker bar to take off the flywheel bolts so suprised they are only on 17 ft lbs + 90*

Please do not post links to those manuals that are out of date and only have a few of 99 supplemental updates. Much of the data has been updated.

From the (up to date) service manual "DMF to crankshaft -- MI0 x 1 x 50 -- 25 Nm (19 ftlb.) plus 120 degrees tightening angle."

That is because the extra 120 degrees tightened past the 19 ft. lbs. is one Hell of a lot more than 19 ft. lbs, and the factory bolts have a locking coating on them..................

Ah yes further reading I found that recommendation has been updated to 120*. Seems I am fine with the 67 ft/lbs I torqued my set.

BTW those manuals do not have the incorrect 90* recommendation. It was poster above. Manual lists as noted 67 ft/lbs.

Where are the updated manuals?

You need to buy them from a dealer - as well as all 99 supplements.

Ok thanks. Let me know if I should edit post to remove previous link to old ones.
