Hydraulic Jacks Pump Assembly

2017 Jayco Seneca 37TS
CHECK THE WELD ON YOUR JACKS HYDRALIC PUMP ASSEMBLY!!

The jacks hydraulic pump assembly weld broke, which let the complete assembly fall, and hang by the wiring and hydraulic lines.

Scary! I know there were also pump bracket failures on the Ford-based Jayco Class C's, looks like the faulty welding issue may be more widespread.

You can rig up a good temporary support till you can get a proper fix. It's quick,easy and effective. I bought a 5 foot piece of 3/4 inch galvanized pipe that will span two chassis crossmembers both behind and in front of the pump. Then buy 2, 3/4 inch pipe floor flanges and screw them on the ends. The floor flanges keep the pipe from sliding front to back etc. Then you can either use safety wire tied around the top connectors and then up to the pipe, or just use ratchet straps to go under the pump and up to the pipe. Worked for me.

Rob, very scary, and very lucky!! We had just entered Colorado and stopped at welcome center. Walking back from welcome center, I thought what's hanging down from RV!! Lucky we stopped, if it had fallen to the ground, hard to tell how much damage it would have caused.


t18skyguy We found an RV repair shop in Fort Collins that got us in and did a more complete weld job that the factory, plus he welded in a brace for more support. Nathan's RV repair in Fort Collins, some quality work at a very fair price. https://www.nathansrvservice.com/

Yep looks exactly like the failure I had. So it’s not E450 specific .... unsettling.

JJ, keep an eye on that weld. One of our members had a triangular gusset welded in the middle of the brackett. It turned out to be a cold weld, and that whole 3/8 steel vertical support broke right off across the top of the gusset. Hopefully, your weld is good. When they fall to the ground, it destroys the pump. So glad that didn't happen to you. Looks like there may be a recall on the Seneca's next.

I had the dealer purge my level up system and top off the fluid level. I was getting false jack deployment signals when driving. When I got it home I crawled underneath and I noticed they put a new hydraulic tank and the shield under the entire unit.

Interesting. I wonder why they would put a rock shield on a Seneca but not a Greyhawk? How close is it to that driveshaft? I'm thinking that maybe I should fab one up for my Greyhawk.
