What trouble shooting have you done? Identify the year, make and model of your rig so people can better assess your situation in order to help. Have you searched this and other forums for information on your problem? Do you have the HWH tech data for your system? If not, it can be downloaded from their web site. Replacing the hydraulic pump motor is necessary at times but it not a very frequent requirement, thus the questions I asked.

The replacement of the motor is not hard at all ---- there are only two screws and a "radiator clamp" (on mine) that hold it on. The replacement motor needed is determined by the model number on your hydraulic fluid tank. To test the motor on mine, I used a pair of jumper cables --- located the hot lead coming to the motor to determine if it was hot or not (that would be another problem if not hot) and then using the jumper cable, I was able to touch the one lead on the motor that is on the back of the motor. If the motor is bad, it will not run --- if it is good, it will run as you have bi-passed the relay. If it runs then I would suspect the relay is bad. Hope this helps some -- also the people at HWH are very good at directing you through the trouble shooting over the phone --- I had one on the phone for over 2 hours trouble shooting my motor problem. I now carry a motor as a spare part.

When mine went bad I had it repaired at an automotive alternator/starter repair shop.

Be sure to thoroughly check and clean all electrical connections before you declare the motor to be toast. On our Alaska caravan 3 years ago we had 2 coaches that had hydraulic motor problems. In both cases it turned out to be a bad ground rather than a bad motor.

We had a situation with our hydraulic motor a couple years ago that turned out to be a blown fuse. I don't know if all HWH systems are the same but ours has 2 inline fuses taped in the harness about 3 inches from the motor. Ours had gotten salt in them from a run through a blizzard in Minnesota. Over time the salt corroded the fuse holders sufficiently to raise the resistance high enough to blow the fuses when the motor was activated. A couple new fuses & holders and all has been well.

I removed battery cables, removed pos cable from motor, loosened hose clamp that holds the solenoids to the motor, loosened the 2 motor case screws on the end of the motor, and it came right out.

The problem with my motor was the internal ground connection from the brush to the case. It was badly corroded. The shop drilled out the old screw post and installed a new ground screw along with new brushes.
