Questions: Using the red highlight above for rear main oil seal installation shows the seal shoulder on the inside. The service manual for universal Jeep vehicles, on page 46, fig. 58 shows the shoulder on the outside. Confused which is correct?

Questions: To install this seal, i have read in the Q/A that oil pan and crankshaft must be removed. However, the service manual has a note on p. 31 that reads "removal of crankshaft may be accomplished only with the engine out of vehicle"...
Can you confirm this, or is it possible to install seal without pulling engine?
Thanks for your help

You can do it with the engine still in. Typically you can just lower the crankshaft from the bottom. Having the vehicle on a lift is easiest.

I just replaced my real seals using a device called a sneaky pete. I removed the oil pan and rear crankshaft bearing cap and seal, then used the sneaky pete to pull the new seal into place. After a few tries the sneaky pete worked.

Questions: Should have added to my previous question, hit wrong key. How far do the side cap seals protrude on a L134?
Question By: Tom Elbert on Aug 10 2016 4:40 AM
The packings should protrude approximately 1/4" from the case. With the oil pan installed, it will force them tightly into the holes and effectively seal any openings.
