Well took apart the d.c. motor. A little water came out And their was evidence of rust. I clean it out as best I could without taking it complete apart. I sprayed WD40 in it loosened it by hand turning back and forth. I checked out the release solonoid and it was good. Hooked it to the battery in the shop and it worked. Now and now I need to figure out what kind of hyd oil to use, seem like I read that it shnould be dexron oil. Help please. Billy

Yes dexron or type A auto transmission fluid is what the manual says you should use. Be sure to dry out the pump motor before putting it under a heavy load. If the insulation on the field windings is wet or damp you could short the field under a load.

Thanks Jim L I think I will run The motor for a while a few times to dry the
inside a little more . There is no oil in the pump. Do you think it would hurt
the pump to run it with out oil for about a minute at the time for a few times?

Would you run the engine in your truck without oil?

OK Dirtfan. I know that an auto engine needs oil to operate. Not knowing the working of the inside of a hyd pump, but knowing the purpose of the pump is to push oil to the ram I thought maybe I could get by with spraying WD 40 within the pump to run it a little while. OK I will just put the unit back on the camper, fill it up with transmission fluid and hope for the best.

Do not run the pump without oil and do not spray WD-40 in it. WD-40 can destroy some types of O-rings and seals. Always lube with the type of fluid that is used in the pump. I also would not run the pump motor to dry it out. It could be damp or wet enough to cause a short. Just dry it out in the house for a few days and you might speed it up by putting a fan on it. Good luck

More problems---I put the hyd unit back on the camper, after mounting the unit
and hooking it up the electricial connections I started to fill the unit with oil. There was no evidence of leakage looking at the unit from the front. I then looked under the trailer and I saw oil leaking. Well I disconnected the unit and removed the hyd unit, checked it out. Under the reservour cover I found pitted
holes. I may have to start saving for a new unit unless I can find a new cover.
