I am rebuilding a Dalaval 75 that is from 1957. It has quite a bit of wear on the side plates (.020 "donut" groove from the rotor) and it needs new vanes, bearings, and seals.
Has anyone rebuilt these pumps before? I need to know roughly what running tolerances are needed between the rotor and side places. I don't think I can trust what is there now as there has been so much wear.
I am guessing right now there is about .020 difference between the rotor width and the bore width. Is this too much (will oil blow by)?
Any help is appreciated.
