I have had an expirience where one jack was stuck somewhat extended. Extended it all the way and sprayed with silicone and it retracted quickly and fully afterwards.
The rear jack that's furthest from the tank was always slow retracting and in that case, I had the springs (2 ea jack) replaced on both rears. Now all four retract quickly...as long as I remember to spray them occasionally.
You do not have to spray anything on HWH jacks to get them to retract. Of course, that is cheaper than really fixing them, which involve either rebuilding or replacing the cylinders. Doug
That was on my way out of the Mexican RV park I was staying at, on the first day of my trip back to the US. The right front jack would not finish retracting and was about 2" exposed. I extended it a bit and tried to retract but it stopped at about 1". Tried to pry it with a 1"X2" but it wouldn't budge.
Extended it quite a way, sprayed it with lubricant, and pressed retract. That time in went all the way up. And off I drove. That was 700 odd miles ago and numerous stops extending the jacks. That one has gone up quite nicely each time.
I was able to use my '94 PowerGear jacks for 12 years without removing and rebuilding them, I'll probably be able to do the same with these HWH I have now. So far, so good, after a year and 2 months with them.
