Hydraulic slide crawls and stops
2017 class A, hydraulic slides and leveling jacks. Engine running, 50A shore
Customer says: The living room slide goes out real slow, then stops before it's all the way out. The pump runs the whole time.
Tests you can run
- Voltage at the pump motor while it runs
- Check the fluid level with everything retracted
- Look for leaks at the hoses, fittings and cylinders
- Look at the fluid in the reservoir while it runs
- Check the slide for anything in the way
- Clamp amps on the pump motor
- Replace the hydraulic pump
- Get under the slide box while someone runs it, to watch the cylinder
