IDT Lift System Identification & Parts Guide

The IDT lift can resemble a Goshen installation at the corner posts while using a different drive inside its central assembly. The reviewed IDT reference describes counter-rotating lead screws and travelling nuts that move the spring system. Treat that mechanical difference as decisive when selecting instructions or parts.

Confirm the drive, not just the winch position

A rear crank is a useful clue on some Viking, Coachmen and Palomino installations, but location alone is insufficient. There are other rear-winch systems. Photograph the drive and central assembly, record labels, and compare them with the applicable drawing before calling it IDT.

Do not apply Goshen’s central-tube greasing procedure to a lead-screw assembly merely because the corner posts look similar. Lubricant type and placement must come from the instructions for the installed mechanism, with friction and holding components treated separately.

Use the diagram as a parts map

The available L&W Engineering drawing is titled for a Palomino 1200 main-tube assembly. It identifies the drive and driven screw assemblies, bushings, brake components, endcaps and springs. Its callouts can help identify a component; they do not prove that every length or part revision fits another IDT-equipped camper.

Record the drawing number and revision alongside the camper details. Where a drawing has a later spring revision, confirm which version applies before ordering. Do not select a spring solely because it appears in the same numbered position.

Record the symptom before disassembly

• Crank movement without normal roof travel: document which drive parts visibly move, from a safe observation position.
• Jerky movement or one end lagging: inspect the route and attachments under the correct supported service conditions; damaged nuts, screws or guides need assessment.
• Failure to hold: stop operating and have the brake/holding mechanism evaluated. Do not compensate by changing roof-height settings.

Prepare a controlled repair

Keep upper and lower drive parts identified throughout the job. Counter-rotating components are not automatically interchangeable. Bag hardware by location and retain photographs of every assembly stack before separation.

Because the source drawing alone is not a complete service procedure, arrange the correct support, disassembly and adjustment instructions before opening the unit. After repair, verify controlled travel, holding, roof alignment and closure. Any recurring bind or movement at an anchor needs resolution before camping.
