The Multiquip 36721 Hydraulic Motor Assembly (Service Only) is a genuine OEM component designed for the MTX80HDR rammer. Sourced directly from Multiquip, this part meets the exact specifications of the original unit installed at the factory, ensuring a direct, trouble-free replacement during service. It is confirmed for use on the MTX80HDR tamper — Multiquip's second-generation 80 lb rammer equipped with a GX120 Honda engine and diaphragm carburetor.
Key Features
- Genuine OEM Construction — Built to the exact hydraulic flow, pressure, and torque specifications of the original motor assembly, ensuring the rammer cycles with proper force and rhythm.
- Service-Only Assembly — Supplied as a complete, ready-to-install motor assembly, simplifying field or shop servicing without the need to source individual subcomponents.
- Confirmed MTX80HDR Fitment — Verified for use on the MTX80HDR rammer, Multiquip's 80 lb second-generation tamper with GX120 Honda engine and diaphragm carburetor.
- Sustained Compaction Output — A properly functioning hydraulic motor assembly maintains consistent stroke frequency and impact energy; a worn or failing unit leads to erratic blows, reduced compaction depth, and accelerated wear on surrounding components.
- Direct OEM Replacement — Matches the original mounting interface and hydraulic port configuration, allowing installation without machining or adaptation.
The hydraulic motor assembly is the core drive component in a hydraulic rammer, converting hydraulic pressure into the mechanical reciprocating force that drives the ram shoe into the ground. It regulates the frequency and power of each compaction stroke, directly determining how effectively the machine consolidates soil or backfill. When this assembly wears or fails, the rammer may lose stroke power, cycle erratically, or stop compacting altogether — making timely replacement critical to keeping compaction results within specification.
