The Multiquip 88022 is a genuine OEM Front Right/Left Rear Hydraulic Motor designed for RAMMAX walk-behind roller models including RW1403HF, RW1404, RW1404MR, RW1504HF, and P33/24 series machines. As a direct Multiquip OEM component, part 88022 is manufactured to the same specifications as the original unit, ensuring a correct, drop-in installation with no guesswork on fitment. DHS Equipment stocks this part to keep your roller running with the same hydraulic drive performance it left the factory with. Confirm your model and serial number against the fitment list below before ordering, as coverage varies by serial number range on select models.
Key Features
- Genuine OEM Hydraulic Integrity — Built to the same internal displacement and pressure tolerances as the original motor, maintaining consistent hydraulic drive output across the roller's full operating range.
- Direct-Fit Installation — Matches the original mounting configuration and port orientation for the front and rear drive positions on covered RAMMAX roller models, allowing straightforward removal and reinstallation.
- Broad RAMMAX Roller Coverage — Confirmed fitment for RW1403HF, RW1404, RW1404MR, RW1504HF (up to S/N 1534188), RW1404MR (S/N 326075 and up), and P33/24 HHMR-BD, FR/FC/FCR variants.
- Sustained Drive Performance — A correctly functioning hydraulic drive motor delivers even propulsion and compaction force across the drum; a worn or internally leaking motor causes sluggish travel, uneven drum speed, and reduced compaction consistency.
- Hydraulic System Safety — An OEM-spec motor maintains correct system pressure balance, reducing the risk of hydraulic fluid bypass, overheating, or uncontrolled roller movement on grades.
The hydraulic drive motor on a walk-behind roller converts pressurized hydraulic fluid from the machine's pump into rotational force, propelling the drum or wheels forward and in reverse. On RAMMAX-series rollers, both front and rear drive motors work in coordination to deliver controlled, consistent compaction passes — making the condition of each motor critical to overall machine performance. When a hydraulic motor begins to wear internally, the roller may lose traction, pull to one side, or fail to maintain consistent drum speed, directly impacting compaction quality and operator control.
