HECO E-Z Up Lift & Hinge Guide

The HECO E-Z Up system uses manually raised external round arms with folding hinges. It appears on some Palomino, Krown and Sunlite campers. It is not the HECO/Harmony crank-driven torsion-bar mechanism used on some truck campers.

Identify every part of the hinge

Think of the assembly as more than two tubes joined by a pin. The upper and lower hinge portions, pivot hardware, bushing and locking sleeve all have a job. A sleeve that will not fully seat, a worn pivot or a distorted tube can compromise the assembly even when the arm appears straight.

With the roof in the safe condition specified for inspection, photograph each complete arm and each hinge. Record missing hardware, cracks, oval pivot holes, bent sleeves and movement at the roof and body attachments. Compare matching positions without assuming that different-looking hardware is an acceptable repair.

Separate a hardware fault from tube damage

• Missing or damaged locking sleeve: identify the correct sleeve and pivot arrangement. Do not treat a straight arm as locked merely because it stays in position briefly.
• Loose pivot: determine which part is worn. Tightening a substitute bolt may bind the hinge without repairing an enlarged hole.
• Broken hinge or bent tube: record the tube size, condition and hinge orientation before selecting a repair approach.
• Loose mounting point: inspect the structure receiving the fastener; the arm cannot correct a failing roof sideboard.

Understand the limits of insert repairs

Some aftermarket repairs replace a damaged hinge end with an insert inside the existing tube. That does not make every tube suitable, or make drilling, riveting and welding interchangeable. The insertion depth, remaining tube condition, joint method and final arm geometry need an approved specification for the particular repair.

Do not cut an original arm until those requirements have been established. Preserve its length and orientation in photographs and measurements. For a structural hinge repair, use a technician who can assess the tube and the proposed connection; this overview does not specify a fabrication method.

Check the finished assembly

Follow the camper’s setup sequence and verify that every lock engages fully without forcing. Inspect the mounting points under normal operation and stop if the roof shifts, an arm bows or a sleeve moves out of position. Keep hands outside the hinge’s folding path. Roof support for service must be independent of the component being repaired.
