Repairing Lift Cylinder
I have just purchased a 2003 17' Hi-Lo. The previous owner was not maintenance minded and had a bent guide rod and a jammed cylinder in the up position. I have disassembled and the cylinder is being repaired. From review of this forum I have a good idea of how to get it reassembled. The comes the commissioning and getting it up and running. So here are some questions.
1. Bleeding: After filling the reservoir with ATF and running the unit up and down, is there any procedure to bleed air out of system. I have no components to do this, so all I can see is to run it a few times.
2. Lift cables: These need adjustment to get all level. What is a practical tolerence to get all measurments the same, front to back, and side ways. Say plus or minus 1/2" or 1/4". Seems like it can be somewhat loose. I want it right but why screw around if it can be a little loose.
3. Plastic Line: I have a plastic line, 1/2" dia from the cylinder back to the reservoir. Is this the return line for lowering the top? Or is it a line to bleed back any fluid that leaks around the piston ? Looks like it can't take a lot of pressure.
4. Tracks: My 17' unit has tracks on the outside at front and back of unit. On the door side there are two tracks along side the door. There is no track at the front of the unit. Looks weird but if everyone else with a 17' has this I can live with it.
Any answers appreciated. I am going over the entire unit, hitch to spare tire to get it shipshape. Fixing loose and corroded connections, cleaning, lubricating, etc. Retired aircraft maintenance man and the lift system looks like a low-tech landing gear system. Lots of fun!
Thanks, Ed Lansing
