HWH Leveling Jacks Retract Problems, 1993 Bounder M34J
I'm seeking HWH Leveling Jack service and repair expertise, anybody?
Three out of four jacks on my 1993 M34J will not retract the hydraulic pistons after the jack has been commanded to the stowed position and pressure has been removed from the jack. The jacks will only retract as much the weight of the coach will push the ram back in, then the swing springs swing them up into the stowed position but with the piston still partly extended. In fact, I have had to drive the coach off of the depressurized jacks in order to get them to swing up into the stowed position. The problem is, because the piston ram remains partly extended, it is too long to be deployed the next time you command them to deploy. The jacks will be to long to swing down to vertical without hitting the ground first, and then can not be used to raise the coach.
I suspect this is a common problem. Does anyone know the solution? Can these hydraulic rams be overhauled? Have the seals become to tight? Is the pump supposed to reverse to draw the piston up?
