2000 Dynasty 36

Hydraulic cylinder powering the slide has developed a leaking front seal (leaks when being RETRACTED). I'm going to remove it and hope it is a rebuildable cylinder. Starting shortly.

Anyone with any experience sourcing parts or repairing this cylinder? I'd like ot hear from you. TIA

Were it mine, I would take it to a hydraulic repair shop and let them either repair if possible, or I would buy a new one. No hassles at my age is a good day.

Your generator slide may be like mine.

I had recently worked with another Monaco owner who's generator slide was creeping out. He ultimately took the Hydraulic cylinder off and took it to a shop and had it rebuilt, they did it in a day so the seals must have been common size.

While you have the ram out I clean the system thoroughly, I've had problem with my lock valve due to contamination. I had to replace the lock valve in the block due to contamination and still have some problems with it seizing up.

Here is some info on the slide assembly

Thanks, Jim! I've gotten the cylinder out, and it's a repairable type. However, I'm not sure it is Power Gear brand. It does not appear quite like your .pdf's and it does not have a cylinder-mounted locking valve.

It's dark and wet here. I'll take another look tomorrow after church. Although there is no hydraulic cylinder I can't repair myself, I might take the other poster's advice and just drop it off at a hydraulic repair shop, assuming there is one in my area. The front seal is leaking.

Thanks to all who replied!

My hydraulic system for the genny slide was an HWH. I got it out and took it apart. Had to machine a spanner wrench to get the head loose. I had planned to order the seals from McMaster but checked with a hydraulics shop about 30 miles from my house. They replaced all the seals in the cylinder head--O-ring for the head-to-cylinder seal, piston lip seal, and rod wiper for $6 and installed them in the head!! Everything is working again.

Thanks for the replies!

I have an external fuel filter on my 7500 quiet diesel and it’s time to change it. I extended the generator to verify the p/n and after retracting it I found hydraulic fluid beneath the coach. I’m on the road so I won’t be able to lol at it until I get home. This post helps a lot. Thanks Van and Jim.

It looks like it’s the ram itself that’s leaking rather than a hose.
