Lippert Jacks

Well... Continuing to have problems with my Lippert Jacks. Half the hydraulic lines have already been replaced from a prior problem. Looks like the others need to be replaced now.

Wow, that looks bad. I think I'll check mine this weekend. They have always been finicky, but I had not noticed bulging lines before.

Update - I brought my motorhome to the dealership today regarding the jacks. I made a mistake in my original post. The orange hydraulic hoses, which I thought were the OEM hoses, are actually the Eaton replacement hoses. My mechanic was very surprised these hoses started to bulge since they are a better quality hose than the OEM hoses. He also said the Lippert Jack System, Unlike Powergear or HWH systems, hold the pressure (approximately 2,000 lbs.) in the hoses which actually adds to the strain of the hoses. These same hoses were replaced approximately 1 1/2 years ago. He is going to give this issue some thought and mentioned about possibly looking into aircraft hydraulic hoses which would handle more pressure. Now, this is just something he mentioned off the top of his head and we don't know how costly or the possibility of taking this approach.

Update #2

My mechanic was able to find a hydraulic hose (Gates 4G2) which is rated at a maximum of 5800 PSI. He indicated the Lippert System maintains a constant pressure of approximately 2,000 PSI when the jacks are up. The former Eaton hoses were only rated at a maximum pressure of approximately 3,200 PSI. The Gates hoses are double walled which is reinforced with braided steel wire. He believes the Gates hoses will hold up better than the prior Eaton hoses. Kudos to Protective Extended Warranty for picking up the repair of over $1600 for four return lines and labor. Keeping my fingers crossed.

Sounds great, John! Hope this is the last hydraulic jack repair you have to make!

I don't think that is correct, the pressure is in the lines on all hydraulic jacks, or at least if the valving is located at the pump and not the ram. To manually lower my HWH jacks, I had to loosen a valve at the pump relieving the pressure in the line to the ram.

I think the lines used in your installation were not of sufficient strength for the job. Hopefully Winnebago did not use them for too long.

Maybe I was not clear in my explanation. That is what I was trying to say which is why the lines were bulging. My mechanic looked for a stronger line (new 5800 PSI line vs the former 3200 PSI line).

Thanks

Hi, sorry, I missed the original post - what symptoms were you (OP) experiencing? I have a 2015 Itasca and the jacks aren't currently working but current thinking is that the motor is bad. I will however, start looking for bulged lines. Were all of the bulges at, or near, the pump area/ Thanks. Anyone hear of motor type issues with these systems? Thanks

The initial problem was the jack down light would come on after the motorhome was sitting a couple days with the jacks in the up position (retracted). They attempted to diagnose the problem by replacing the return lines because they were bulging. At one point, they replaced the motor because it was leaking fluid. Now the replacement lines started to bulge, so my dealership looked into a higher pressure hose (Gates 4G2 Hose - see post above). Only time will tell...

Thanks. I'm going through the motor replacement part of it now - confirmed the motor was bad. Were all of the bulges at or near the pump or should I follow all of them all the way to the jacks? I'll try to check them this weekend.

With my motorhome, at about the 3 1/2 year point, I had to add some fluid into the hydraulic reservoir to keep the 'jacks down' alarm from going off when rounding a sharp curve.

At the 5th year annual Freightliner checkup, they noted there were some bulges in the hoses at the rear levelers. I checked at the pump, and there were bulges there too, and who knows where else along the hose lengths. I also added a bit more fluid at that point.

Later that summer, we were at Winnebago, and I had all four hoses replaced. Luckily it was covered by my Good Sam Extended Warranty plan.

I only noticed bulges near the pump. I just noticed a leak at one of the fitting(fitting that goes into the black portion of the pump) yesterday. It is now back at the dealership for repair. Mechanic said it is the O-ring.

Well, first trip out and the fluid is leaking at the o-ring that was just replaced at the pump (see photo). If you look at the picture closely, you can see fluid around the o-ring and on top of the black part of the pump. Last time I spoke with my mechanic, he made mention about using the stronger lines and the system looking for the next weakest point. I think the system found it. Only seems to leak when the jacks are in the up (retracted) position. Motorhome going back to the dealership on Monday.
