I just bought a 1988 HiLo and LOVE IT!
We got it home and raised the roof to demonstrate to the family some of the features. While we were taking a look I noticed a few details that I either overlooked during the pre-buy inspection or that weren't present then:
1. The upper/lower seal is not being made...the top doesn't raise enough to come into contact with the seal. The pump runs, the top half lifts until the safety lock engages with a 'thunk' and then the pump squeals like the owners manual says...but the top doesn't lift all the way to make the seal.
2. When I folded out the top bunk and propped it up on the legs, it was out of level...further confirming my suspicion that the top half is only telescoping to within about 3" of 100%.
When I went outside and inspected the exterior, I found an alarming puddle of hydraulic fluid underneath the cylinder.
Whoops.
So, I'm looking for the most efficient way to repair this.
It looks like the pulley plate that slides on the guide rod during extension has moved further than it presently is. I'm thinking that maybe the hydraulic system, if it's leaked during several lower/lift cycles, may be low enough in fluid to not have enough to complete the last 3" of roof extension.
I can see the pin that mounts the cylinder on the stationary end and that the other end (the piston) is threaded to the pulley plate. I can envision how you might lower the top onto 2x4s on end to take some tension off the cables and remove the cylinder...it probably just needs new seals.
Has anyone here been through this before or have any input?
