I'm having trouble again with my HWH leveling system. Specifically, the front right and rear left jacks will not retract. I called HWH and talked to tech support and was told how to trouble shoot the problem. I went out and put the jacks down, then tried to raise them. They retracted without trouble. We went to Mexico for the winter and would try to retract the levelers the night before we were to move and they never failed to retract. Not once!! Last weekend, I had a hard time getting the rear leveler up, but the front right would not budge. I had to dig under the leveler and use my Jeep tire change jack to get the leveler back in place. I decided that enough is enough and want to get new cylinders for these two levelers. The two rear units are both model AP-19670, as I would suspect. However, the two front units have different model numbers. One is AP-18813 and the other is AP-953**. The last part is unreadable, but it is NOT the same model as the other front unit. Any ideas why this would be so?

It may be a replacement jack. Here is the HWH parts catalog link.
the front jack cylinders will be the same. the AP number is for the whole jack assembly. there may be a sight difference in the configuration of the assembly, thereby causing a different ap number being used on the assembly. go to the hwh website and look in the customer assistance ares. there is a quick reference guide for jacks that give a cross reference to all the replacable parts related to that jack. just look up the ap number on the left side of the page, and there will be a rap number for the cylinder to the right
I went to the HWH site and found that AP-18813 is the replacement for the older AP-953 series. I guess one of the previous ownwers already changed the front left one. HWH was a bit slow getting back to me and by the time they did, the cylinders were at the hydraulic shop. Talking to the owner over the phone, he seemed to know exactly what I had, including the micro-switch that shows the jack all the way up.
Removing the front jack was easy, after taking off the right front tire. With the rear jack I was not so lucky. I had to remove the rear wheels to get to the jack, but still could not get at the fitting. When I tried to loosen the connection, it would twist the pressure line and I didn't want to replace that. There is a swivel connection that was stuck. I applied a sawsall to the fitting coming off the cylinder. Then, with two wrenches I was able to loosen up the swivel connection, so it should go back fairly easily. I hope. I'll have the refurbished jacks back next week.
