Hi all,
I am working on the hydraulic pump on a SL150 lathe. The problem started with the overload tripping after about 10 seconds of run time on the motor. I pulled the motor off the hydraulic unit and found the oil seal had failed and the motor had filled with hydraulic oil.
I drained the oil and cleaned the inside of the motor out as best I could with compressed air. New bearings have been installed along with a new seal. The motor turns fine and I checked the windings with an ohmmeter. No shorts to ground and all three leads read about 5 to 5.5 ohms.
What should I be seeing for resistance normally? Can I check anything else out on this without sending it out? The motor will be replaced if necessary, I'm basically trying to get the machine up again as quickly as possible.
The motor has been reinstalled and has the same problem, 10 second or so run and trips the overload. Am I fighting a losing battle here? Just wondering if I should try something else, or just order a replacement motor now and wait it out. I just want to be sure that the motor is the issue, and nothing else is causing grief.
Any help here is appreciated, thanks,
Kevin
