Bob Doh Posted April 8, 2021 Share Posted April 8, 2021 I have a hydraulic leak on one of the pistons that operate the living room slide. I’ve traced the leak to the tube that houses a piston. Cannot see the piston, but have oil dripping out next to the outboard side of the slide. Has anyone attempted to pull the piston out , and is it repairable? My coach is an 2003 Dynasty Before I get up the gumption to pull it, any advice would be appreciated. Bob D Link to comment Share on other sites More sharing options...

Bob Doh Posted April 9, 2021 Author Share Posted April 9, 2021 Wow!!! Thanks for the story! that’s good insight,,, not to happy about cutting a notch in the trim. Bob Link to comment Share on other sites More sharing options...
Twomed Posted April 10, 2021 Share Posted April 10, 2021 (edited) Just did one on a friends 2003 Safari Panther on the RR10S chassis and the cylinders came out the pass side...no trimming of anything. A four slide config may not allow this, but check it out. Also very important that you synch the new cylinder(s) before operating, or the slide will come in crooked and jam. HWH online manual has the procedure. Edited April 10, 2021 by Twomed Link to comment Share on other sites More sharing options...
Ivylog Posted April 10, 2021 Share Posted April 10, 2021 Shade tree here...if leak is minimal, put a diaper on to catch the leak and oil is cheap. After moving, bump the opposite direction to take the pressure off. I’ve had good luck putting Lucas transmission seal additive in the hoses going to a leaking cylinder on a machine.

Rob M cKeown Posted April 10, 2021 Share Posted April 10, 2021 I have replaced the slide cylinders on both HWH Slides on my 2003 Signature and had the Slide Cylinder seals replaced by a local Hydraulic repair shop. If I remember rightly it was about $40 per cylinder. Synchronizing the cylinders is important and the HWH Manual has the procedure Link to comment Share on other sites More sharing options...
wamcneil Posted April 10, 2021 Share Posted April 10, 2021 Also, consider having the sync cylinder rebuild while you’re in there. Mine started weeping shortly after I had all the rams done cheers Walter Link to comment Share on other sites More sharing options...

Bob Doh Posted April 11, 2021 Author Share Posted April 11, 2021 Thanks to all for your input. It’s been a great help. Tomorrow, we go to work and pull the cylinder,, and may do the other side if all goes well. Considering the sync cylinder as well, assuming it’s the one on the basement ceiling wit a long exposed rod , that runs north/south..

Rob M cKeown Posted April 11, 2021 Share Posted April 11, 2021 As a matter of interest, on my 2003 Signature with 3 slides, the two front slides extend different lengths, the Driver Side extends further than the Passenger Side. Both sets of cylinders are the same length physically but do not extend the same length. The passenger side Cylinders have an internal spacer to eliminate the possibility of extending too far. When you remove them make sure you identify where they came from if you are doing them all at once. Link to comment Share on other sites More sharing options...
Bob Doh Posted April 11, 2021 Author Share Posted April 11, 2021 Good point! I have the same configuration. thank you for your input. Bob Link to comment Share on other sites More sharing options...
Tufffish Posted April 14, 2021 Share Posted April 14, 2021 We just had ours fixed. mobile rv man took cylinder off for us and we took it to a hydraulic shop to be reworked. it cost $119.00. Mobile rv man put it back on and it works perfectly. Large slide now works like it was brand new!!! The trick is to take the cylinder to a hydraulic shop for repairs. We tried three different repairs guys before we made the right choice! tufffish 2001 Monaco Signature Link to comment Share on other sites More sharing options...
