Old Ugly; Need some Torque Specs.

[GHarman]

Would anyone be kind enough to provide some Torque Specs for the Oil Pan bolts, Rear main seal retainer plate and the bell housing adaptor plate on the 91. 5/12 valve Cummins? I have no idea where to look other than call the Cummins Service Desk and hope that they would be kind enough to provide that info. Thank you in advance Oo. . GregH

Pan bolts 18 ft. lbs. , rear main seal retainer 7 ft. lbs. and 30 ft. lbs. trans to engine, although I would probably go much tighter on the trans to engine bolts. These specs are out of the 92 FSM.

Hey Tim, Thanks! Question? The "trans to engine" you mentioned, is that the bell housing adaptor plate that goes over the rear main seal retainer plate and bolts directly to the back of the engine with 8 bolts? Thanks again. GregH

More torque specs needed.

Anyone have Torque Specs. on the bell housing to bell housing adaptor ( aluminum ) and the transmission to bell housing and the transfer case to transmission? Thanks in advance. GregH

How about a torque spec. for the U-joints on the rear drive shaft, the one u-joint on the front Drive shaft and the 4 bolt plate for the t-case to front drive shaft. As well as the T-case to transmission listed in the previous post. Any resources for this info would be appreciated. Thanks, GregH
