CJ2A main cap bolt problem... - Pirate4x4.Com : 4x4 and Off-Road Forum

A friend recently got a 48 CJ2A. The jeep has sat for 7 years since
running. The engine (L-134) would not turn over with the starter or by pulling
the jeep, aka the engine was froze. We pulled the head, checked the
cylinders for rust, pulled the pan and loosened the main bearings. Once
we loosened the bearings the engine freed up. I pulled each main cap
and the bearings were in great shape. I applied a liberal amount of
engine assembly lube and put each cap back on. I torqued the bolts to
30ft lbs first, and then to 60 ft lbs, then to 68 ft lbs. When I went
to torque the bolts to 60 ft lbs, the bolts barely and I mean barely
turned before the torque wrench clicked and then the same for 68 ft
lbs. Does this seem right? Maybe I'm just over reacting or something.

thanks

Once its tightened against the journal it doesnt take much to bump the torque up. I am rebuilding a 47cj right now but going more in depth than just look at it and lube it. Just turn the motor over a couple times by hand and check the torque again if your really worried but as long as the wrench is accurate I wouldn't worry.
