Hi Folks -

I'm in the process of rebuilding my first volvo engine and am looking for some help with a bearing issue. It's a 240 engine: 1989, B230F.

I have gotten the engine back from the machine shop - it was cleaned and honed. It was not re-bored so I am using the same pistons and have replacement rings and bearing sets - all standard (no oversizes). The engine is currently on a engine stand.

I've completed the camshaft install - all good. After the new main bearings were installed and bolts are at torque - it spins just fine. I've installed the new rings to the original pistons, installed the new connecting rod bearings, installed the pistons to the block and have dropped the caps in place - all bolts are finger tight only.

Here's the crux: When I finger tighten the caps, I can turn the camshaft (and pistons) with effort, but smoothly. I re-attached the flywheel to get a better grip. But when I start to tighten the connecting rod caps - I am unable to move the camshaft. Once at torque (15ft/lbs) the cam does not budge. According to my Bentley manual, I still need to give it a 1/4 more turn (i've not taken it that far).

I've gotten oil to all the parts that need to move, so I do not believe its simply friction - my gut says its the wrong sized connecting rod bearings but I've double-checked the part number (its the right bearing set).

Is an engine with without compression, but with new rings, main and connecting bearings, supposed to be moved by a mere mortal - and by hand? Am I just not giving it enough umph?

Can I move forward with the rest of the rebuild with this much friction? I am concerned about blowing the whole engine if this is not correct.

Thanks,
Jim
