Hi everyone, I recently purchased a 2005 Coachmen 1272ST popup and after poking around the Internet a bit, including the previous posts on this site, I discovered that there was a safety retrofit on the IDT lift system that it came with. I don't think my camper was fitted with the add-on clutch mechanism that was part of the upgrade, although it does have the round crank socket rather than the square one. There is no sticker on the bumper indicating that the upgrade was done. I called Viking and was told that no records exist anymore of the upgrades that were performed and there seems to be amazingly little information on the web about the IDT lift mechanism and its operation. Does anyone have any pictures of the add-on clutch and its location, or a picture of the part that fails that prompted the recall on the lift? I have a machine shop, so if it is a matter of replacing a broken part with a better one, that's not a problem. If you have pictures or diagrams of the lift mechanism itself and a disassembly prodedure for the master shaft I would greatly appreciate if you could post them.
