Oildyne 108 hydraulic pump from 72110

I acquired this recently but the deck lift wasnt working, fuse was blown for the hydraulic pump and having removed it and stripped down the motor end it was full of water and rusted up pretty bad. Does anybody know what the stator windings resistance should be ?? Mines a dead short !

Clean it with some spray electrical cleaner. Use something like a tooth brush to gently scrub it. Test cleaner on a small spot of insulation and wait 30 minutes to insure it doesn't soften insulation.  

Set it in the hot sun, or in front of a heater (not to close) rotate to heat all sides, 100F -120F to slowly drive out moisture. All day, maybe 2 days. 

Then recheck resistance.  don't worry about a resistance "number for the 1st step", you just want to get away from the dead short. 

Once you get away from the short, you can warm it some more to see if it resistance improves.

 

Show us some pictures of everything.

You will probable need to go to a hydraulic shop with you parts and old O-rings to match some new one up. 

A good industrial hydraulic will have flat file drawers full of every size and type O-ring. 

You want something like a Viton material, not exotic, just oil resistant compared to natural rubber.
