oil pump binding..
 

I am assembling a 2.7 for my R clone and have concerns re my oil pump. I have cleaned and inspected it and it turns very nicely by itself. when I connect it to the intermediate shaft and lay it in the case half, when turning the intermediate shaft gear, the pump spins freely, but moves slightly on the three bolts. I swapped the position on the spines and it still moves slightly. When I bolt the pump in place and turn the intermediate shaft, there is a very slight bind in one spot. I am wondering if one of the shafts in the pump could be slightly bent? It is a very,very slight bind, and not rough like metal fighting metal. Just a gentle bind. Replace or bolt it up? I disassembled it a couple times to see if I could determine the cause, but everything looks perfect inside and it rotates freely by itself. Any thoughts:confused:

HI Speedo
When you have the pump and the intergear bolted in the case, can you slide the connecting/drive tube easily from cir clip to cir clip, as you have the pump running free out of the case and it only binds when in the case, I would look at the shaft or intergear/bearings for correct location.

shaft is free
 

When bolted in the case, the shaft will slide relatively easily from side to side. I looks as though one of the shafts in the pump (maybe the output) has a minor bend to it, although it is extremely hard to tell. I think I will mount my dial indicator somehow to see if there is any deflection as the oil pump output shaft is rotated.
