We had a 99' Coleman PUP where I thought I was being proactive and sprayed lube into the crank area. The next time it wouldn't crank up...The crank box for my 99' was mounted just above the rear bumper. I was told by the dealer it was not meant to be lubed because it worked on a friction system where two cork washer like objects rubbed together and that what would cause the gears to in-gauge. By lubing it, the 2 discs would just keep slipping and not in gauge the crank gears. I had to drill out the rivets under the crank box and wipe off the lube I had applied. Now this "crank box" was mounted outside the trailer so it was easy to get to, but in later models I think the crank gear box was mounted higher on the back wall of the trailer.
I have a 05' brochure I'm looking at now and it has a picture of the construction of the PUP without and walls. And yes, The part you put the crank in is about 3' off the ground, then there is a chain that connects another gear at about bumper level...from there there is a rod about 2 feet long that goes under the floor and is then connected to a bunch of cables.
I wonder if that chain that goes from the crank handle to the bumper area gearbox broke. The length of the chain, that looks like a bike chain. would be about 1.5 feet. I wonder if you look under your bumper can you see the lower gearbox. On mine before I drilled out the rivet I was able to peek inside and see that the washer things were not in-gauging.
