What to do if power unit does not slide out?
1. Check to see that 10A fuse in the pump harness is good and seated in the receptacle properly. 2. Test the pump unit by operating the slide-out. A. If power unit operates slide-out, we know that the problem cannot be the power unit. B. If power unit does not operate the slide-out, there is an issue with the power unit.
How does a reciprocating positive displacement pump work?
On the down stroke, water passes through valves, set in the piston, into the upper part of the cylinder. On the next upstroke, water is discharged from the upper part of the cylinder via a spout. 12. Reciprocating Positive Displacement Pumps 1.2 Force pump In a force pump, the upstroke of the piston draws water, through a valve, into the cylinder.
Is there a manual override on a slide out motor?
1. Unbolt Power Unit Mounting Plate from the floor of the storage compartment and turn it to access the manual override in the end of the motor. NOTe: DO NOT manually override both the slide-out and the jacks at the same time. 2. Remember to always extend the leveling jacks first and then extend the slide-out.
What happens when inlet valve a is lifted on a hydraulic pump?
When inlet valve A is lifted by the pressure of the suction head, the slurry completely fills the pump cavity. The diaphragm returns to its normal convex position and the air exhausts. Discharge valve B, seated by line pressure, prevents slurry from returning to the pump cavity. 24.
What causes a slideout in a hydraulic system?
A hydraulic system leak can be another cause of slideout problems. The first thing to check is your hydraulic fluid reservoir to ensure there is enough fluid in the system. When your slideouts are out, or your leveling legs are down, the reservoir will have a lower fluid level.

How can I tell if my slide out pump is leaking?
If the motor/pump runs but the slideout doesn’t move and there is low / no fluid in the reservoir, then you probably have a fluid leak. You will need to trace the hydraulic lines from the pump to the operating rams to see if you can find a leak in the system. Check your owner’s manual to see specifics about your hydraulic system.
