The Multiquip 355447200 Pinion is a genuine OEM component designed for MT-75H and MT75HS rammers. As a direct OEM replacement, it is manufactured to the same specifications as the original part, ensuring proper mesh engagement within the drivetrain. Verified fitment covers the MT-75H and MT75HS tamper models, so you can order with confidence knowing this pinion is the correct part for your machine.
Key Features
- Genuine OEM Gear Geometry — Machined to exact tooth profile and pitch specs, maintaining proper meshing contact and load transfer within the rammer drivetrain.
- Drop-In Drivetrain Replacement — Engineered to install directly into the original gear housing position with no modification to surrounding components.
- Confirmed Fitment for MT-75H and MT75HS — Validated against Multiquip rammer model codes MT-75H and MT75HS for accurate parts sourcing.
- Sustained Compaction Force Delivery — A correctly sized and seated pinion ensures full reciprocating stroke output, keeping impact energy consistent across every compaction cycle.
- Wear-Resistance Under High-Cycle Loads — Rammer drivetrains operate under repeated percussive stress; an OEM pinion is built from materials rated for that duty cycle, resisting premature tooth wear and fatigue.
The pinion is a small-diameter gear that meshes with a larger gear in the rammer's internal drivetrain to transfer rotational power from the engine into the reciprocating motion that drives the foot up and down. It plays a direct role in determining stroke rate and impact energy — if the pinion teeth wear down or the gear fails, the rammer will lose compaction force or stop cycling altogether. Replacing a worn pinion promptly restores full drivetrain function and prevents secondary damage to mating gear components.
