I have an oil pump gear that was most difficult to remove. Its out not bent. Ok it will be just as hard to press in and I do not want to do anything w/out proper advice. It is supposed to turn freely. What should I do?
 
The oil pump shaft must be able to turn freely.  If it doesn't, you need to find out why... lots of possibilites, mostly DPO-related.  If all is OK, it is also very easy to extract/replace.

Remove the little round drive peg before checking for ease of fitment and rotation.

Personally I'd probably start by removing the oil pump body, cleaning it all, checking the shaft for free rotation in the body and no damage on the inside mating surfaces where the pump gears run, then check for free movement (but no play) in the bushed hole in the cases. If all seems fine, refit the pump body according to the process outlined in one of the manuals ... there might even be instructions in a thread somewhere on here.

Very simple mechanism, should be easy peasy if everything is straight and surfaces/contact areas/bushes are smooth.
