Another HWH slide and jack problem
HWH leveling jacks and 4 slide hydraulic mechanism. On a trip and for last 4 months the system has been working flawlessly. A couple days ago one slide wouldn't come in. Pump was running but sounded like no pressure, the same sound when relief valve is open on a control valve. I extended the jacks, did a retract and the slide came in. That situation repeated itself earlier today when we changed parking sites and when I went to level, the jacks wouldn't extend. Same pump running but no pressure sound. I had started extending one slide, the problematic one earlier, and when the sound was wrong and it was slow stopped and tried to retract. It slid in an inch but is now out about 1 inch. Left front slide. Checked fluid, a bit low, added a quart, no change. Opened relief valve on control valves, cycled extend/retract switches, closed valves, no change. Checked all wiring, all OK. I tried the manual retract on the one slide and the 2 13/16ths nuts spin freely and don't provide any resistance to crank the slide in. I crawled under and nothing to see where that rod connects on the inboard side.
At this point we are going to head home and I'll work on it there or take it to be fixed. We've been on the road for 3 1/2 months and were planning to head back next week anyway. If anyone has any additional thoughts, I'm all ears. My tools are limited unfortunately. Looks like a 2 day, 550 mile drive back with no slide or leveling. Thanks in advance
