Oil suction lines

[maple cove]

Hi all. i have a 76 Delaval vacuum pump. I took it apart and changed bearings, it sucks great but now I have air blowing out the oil lines to reclaimer. Did I do something wrong when I put it together again? Thanks Vernon

Has anyone had or heard of air blowing out of oil lines going to reclamer? Thanks Vernon

Found the problem, put a new gas motor on pump and was trying to match up pulleys, had the pump intake line open with no restriction, when I closed it off some, the oil was going through fine. Sometimes the toughest problems is over thinking. I told my wife what it was doing and she said it could be the motor..... a light lit up in my head just like that. Vernon

Good find. I often get puzzled with problems and try to think up all sort of reasons, then when I figure it out I don't see why it was not immediately obvious.

Yes, seems to be the norm, also some stuff is way harder at 72?
