When your 5th wheel's power landing gear stops responding, the motor is often the culprit. This is the OEM-spec standard-speed replacement motor for compatible Lippert and Venture power landing gear assemblies -- restoring full electric operation without replacing the entire jack assembly.
Lippert part number 142178 (vendor reference 71-3764) is the correct standard-speed drive motor for Venture-brand power landing gear systems found on a wide range of 5th wheel RVs. It replaces the original motor when the gear no longer extends or retracts under power, runs sluggishly, makes grinding noises, or fails to respond to the control switch altogether.
This is a direct drop-in unit designed to mate with the existing Venture landing gear gearbox and mounting configuration -- no drilling, no adapter brackets, and no re-wiring a different motor family. The motor's output shaft, bolt pattern, and electrical connector are matched to the original Venture standard-speed assembly specification.
Engineered to the same shaft, bolt pattern, and connector spec as the original Venture standard landing gear motor.
Matches the standard-speed motor designation -- not the high-speed variant -- for correct operation with compatible gear assemblies.
Runs on the RV's 12-volt DC house/chassis power, consistent with all Lippert and Venture power landing gear motor designs.

This motor is the direct service replacement for the drive motor in Venture-branded standard-speed power landing gear assemblies as used on many 5th wheel trailers. If your landing gear was originally powered and operates at the standard (not high-speed) rate, and the gearbox/jack assembly itself is mechanically sound, replacing this motor restores electric operation without sourcing a complete new jack assembly.
Common failure symptoms that point to the motor rather than the switch, wiring, or gearbox:
Lippert and Venture produced both standard-speed and high-speed landing gear motor variants. Part 142178 is the standard-speed motor. Check the label on your existing motor or the sticker on your landing gear assembly for the speed designation before ordering. Installing the wrong speed motor can result in mismatched operation with the control electronics.
Replacing the landing gear motor is a manageable DIY job for most 5th wheel owners with basic hand tools. The process generally involves:
This listing is for the replacement motor only. The landing gear gearbox, leg tubes, mounting hardware, wiring harness, and control switch are not included. If your gearbox is also damaged or seized, a complete landing gear assembly may be required.
Replacing the motor restores electric drive capability but does not change the rated load capacity of the landing gear assembly itself. Always observe the original weight rating of your Venture landing gear system. Never use landing gear as the sole support when working under the trailer -- use rated jack stands.
