L&W Lift Guide: Jayco, Coachmen & Viking

The L&W lift uses a main cable, a distribution block and individual corner cables to move push springs into the telescoping lift arms. It is associated with many Jayco campers and some Coachmen, Viking and other models. Confirm the installed mechanism; a brand name is not a universal parts specification.

Identify the cable path

The winch is often inside a cabinet or seat area. Its main cable reaches a distribution block, commonly called the harness square, where the corner cables connect. Pulleys and tracks route those cables to the push springs at the corners.

Photograph the complete route before any cable is removed. Label the four corners on a sketch and match each cable to its destination. Include whether it passes above or below each pulley and where its guides and retainers sit.

Diagnose the pattern before adjusting

• All corners resist: check setup and obvious obstructions, then assess the winch and shared drive path.
• One corner lags or binds: inspect that corner’s cable route, pulleys, spring track and lift arm. Adjustment alone will not fix a seized pulley or bent track.
• Cables twist near the harness: the bearing and distribution-block assembly need inspection. Do not keep winding a tangled cable bundle.
• The roof settles: stop operation and inspect the holding mechanism through the appropriate service procedure.

Check what supports the hardware

Floor and sidewall damage can allow pulley brackets or tracks to move. Examine their attachment points before buying a cable. If the structure is soft, split or pulling apart, plan that repair as part of the lift job.

Before disconnecting a cable, arm, winch or spring, establish independent roof support and the unloading method required for that installation. Do not lift a failed corner by hand while another person continues cranking.

Keep winch and lift instructions distinct

Read the winch’s exact model label. Dutton-Lainson brake-winch documentation warns against lubricating its brake components and requires its safety hardware to be assembled correctly. A camper extension hub can differ from the standard handle shown in a general manual; confirm the applicable installation instructions.

Use the camper’s specified roof-height references after component faults are repaired. Different arm configurations have different targets. Do not choose a number from a different Jayco or force the roof higher to stretch the canvas.

Verify the result

Confirm correct routing, secure brackets, restored covers and smooth movement at all corners. Check the door and roof closure through the proper setup sequence. Keep a record of the repaired component, cable specification and final measurements for future maintenance.
