4.7 big end bolt torque settings...
 
Hello everybody...
I'm only new to the forum, however not new to owning Jeeps.
I'm onto my 5th Jeep at present.

1. I 've had a 1999 Cherokee sport from new...
2. Next was a 1997 TJ Wrangler (wifes car)...
3. Then I got a New WH in Australia/WK 2005 Grand Cherokee which I still have now...
4. Upgraded the wifes TJ 1997 car to a TJ 2002...
Then I sold the TJ 2002 and gave the 2005 WH Grand Cherokee to the wife...
5. I now bought a WJ 1999 4.7 V8 as a project car with worn big end bearings...which I have now replaced...

Hence, my question, does anybody now the torque settings for the big end bearing caps on the 4.7 V8 ???

Thanks to anyone who can help...
Otherwise, I might need to get hold of a workshop manual if anyone nows where I can get one...

Cheers.

Head bolts, page 9-84:
"Note: The cylinder head bolts are tightened using an angle torque procedure, however, the bolts are not a torque-to-yield design." The manual also details how to check the bolts for stretch, flat edge on the threads.

Bedplate bolts, page 9-104:
The manual does not specifically state whether the bolts are TTY or not. There is a tightening procedure for three different sets of bolt. The 'main' bolts are "Tighten bolts 1-10 to 2.8 Nm (25 in lbs). Turn bolts 1-10 an additional 90 degrees."

Rod cap bolts, page 9-112:
"CAUTION: Connecting rod bolts are torque to yield bolts and must not be reused. Always replace the rod bolts whenever they are loosened or removed."
