HWH Jacks Not Lifting the Bus...84 FC

[Scott Forman]

I had a similar problem, and eventually they quit lifting all
together. Needed a new motor. Replaced the motor/tank assembly with
HWH parts, now they work like new, will lift the bus entirely off the
ground. Wasn't terribly expensive. I did the switch myself...was a
bit frustrating at times, but not difficult. Just make sure you mark
which hose is which before you disconnect them.

You may also want to try changing out the solenoid strapped to the side
of the motor, but if the motor runs, I doubt that is it.
