Hey mark
Thanks for that. So I had 3 motors pulled apart and when the shop owner moved stuff around things got mixed up. It randomly hit me that I was missing a set of pistons. Of course that set matched.
So the reassembly started but was short lived. The main bearings are nicked. Contacted company to request replacements and will get back to it after that.
Clean them up with a scotch brite pad.
The way they stack the bearings in the packing causes those marks, nothing to worry about.
