. The second to the last link on the page is for the Coleman Lift Systems repair manual.Does it go up a few inches and the crank stops turning, or does it go up a few inches and the crank turns but nothing happens?There are several possibilities of what may be wrong... whiffletree shaft broken or jammed, pulleys out of whack, something broken stuck in the whiffletree housing...One suggestion: If you intent to take off the whiffletree cover, crank it up as much as you can, which will hopefully be higher than the bunkends. Pull the bunkends out a couple inches, then lower the roof until it is resting on the bunkends, then turn the crank a few more turns to slacken all of the cables. Otherwise you will never get the cover off with tension on the cables. You'll need a 7/16" open end wrench (I found it helpful to grind down one side a bit) and a 7/16" socket wrench with a couple different length extensions and maybe a "wobbly".It may also be helpful to get the tongue onto the ground. I put a scissor jack under the coupler, jacked the tongue up with the scissor, retracted the tongue jack, then lowered the tongue all the way down. This made it a heck of a lot easier to work under the aft end of the PUP. ***BUT*** You do not want to crank the roof up and down more than a couple inches like this... you would be putting a lot of strain on the liftarms by being so far off level.
