The Multiquip 366345170 Pinion Drum MTX 70 is a genuine OEM component designed for MTX70HF, MTX70HDR, MTX70HD, and MTX80HDR rammers. As a direct OEM replacement sourced from Multiquip, this drum is manufactured to the same specifications as the original part it replaces. Verified fitment across the MTX70 and MTX80HDR rammer series means you can order with confidence that 366345170 will install correctly without guesswork.
Key Features
- Genuine OEM Construction — Manufactured to the same dimensional and material tolerances as the original pinion drum, ensuring correct gear mesh and drive engagement within the rammer's impact mechanism.
- Direct Drop-In Replacement — Engineered to mount and align exactly as the factory drum does, working with existing drive components in the MTX70 and MTX80HDR rammer assemblies.
- Confirmed Rammer Fitment — Compatible with MTX70HF, MTX70HDR, MTX70HD, and MTX80HDR Multiquip tamper models.
- Sustained Impact Performance — A properly functioning pinion drum transfers power from the crankshaft into the rammer's ramming mechanism consistently; a worn or damaged drum leads to erratic blow frequency and loss of compaction force.
- Long-Term Drive Train Integrity — OEM-spec tolerancing on the pinion teeth prevents accelerated wear on mating components, preserving the overall drive assembly over extended service cycles.
The pinion drum is a core power-transfer component inside the rammer's drive mechanism. It meshes with the crankshaft drive to convert rotational engine output into the up-and-down ramming action that delivers compaction force into the soil. When the pinion drum becomes worn, chipped, or damaged, the rammer loses impact consistency, produces irregular blow rates, or may stop cycling altogether — all of which compromise compaction quality and increase operator effort.
