Rieco-Titan's four-corner mechanical jacks and manual convertible jacks both raise and lower a truck camper with a crank, but their drive-head and mounting arrangements differ. Identify whether your jack is a fixed mechanical design, a removable convertible gearbox or an electric powerhead before choosing replacement parts.

Factory exploded mechanical jack parts diagram

The Rieco-Titan four-corner mechanical jack exploded drawing (PDF) identifies the gearbox cover, two bevelled gears, shaft, bearings, nylon bushings and inner/outer jack tubes by factory part number. The illustrated mounting version is C-clamp; fixed-plate components may differ.

For the separately designed convertible jack, see Rieco-Titan's convertible jack installation and operation drawings (PDF).

Which jack design is installed?

Mechanical four-corner jack

Manual crank gearbox attached to the jack post, with fixed-plate or C-clamp mounting options. For electric operation, Rieco-Titan specifies the mechanical-jack conversion kit, not the convertible-jack upgrade kit.

Convertible four-corner jack

Designed with a removable manual gearhead and jack post that accepts the specified electric powerhead upgrade. The 14032 set is two black jacks, rated at 2,000 lb each; the crank and mounting brackets are not included in that listing.

Crank, drill adapter or electric conversion?

The 14334 crank handle is for Rieco-Titan manual four-corner and convertible gearboxes, while the 11094 drill adapter operates compatible manual crank heads through a drill. Converting to power operation requires the kit intended for your mechanical or convertible design. Rieco-Titan's factory installation guides show the gearhead removal and motor drive connection.

Safe operation and mounting checks

Check bracket design, camper-wall reinforcement, jack load ratings and ground contact before operating. Rieco-Titan's instructions call for raising the front corners in small increments, then bringing the rear level without ever raising the rear above the front. Keep the camper stable, disconnect truck tie-downs before unloading and avoid extending jacks against their built-in travel stops.

For bracket sizing and swing-clearance options, use the Rieco-Titan bracket guide. If your jack has a 12V electric powerhead, use the electric camper jack parts guide. See also the heavy-duty tripod jack guide, which covers a different mounting system.
