Question Lazy leveling jack

[Joe Hogan]

One of the rear jacks is very slow to retract and does not fully stow/retract.
Thoughts on how to correct this?

@Joe Hogan I had / have the exact same problem on both rear jacks on our DutchStar. Issue seems more prevalent when it's cold out i.e. 50 degrees or less. 1st attempted fix was to put some spacers (approximately 1") in the upper eye bolts that hold the top of the springs. The spacers raise the eye bolt and put a bit more tension on the spring, this helped some but ultimately HWH agreed to replace the jack. The test HWH required was to remove the hydraulic hose that goes to the jack and see if the ram goes in, in my case it did not thus eliminating a restriction in the line or the solenoid as a possible cause. My rear jacks are still slow but I find spraying WD40 and or a PTFE based dry lube and wiping the rams down occasionally does seem to help.

On another forum @Dutch Star Don mentioned using a strip of 35mm film to slide up the seal around the entire jack after cleaning to get rid of the junk that’s in the seal.

I have the film and have not yet tried myself.
