Multiquip 363456410 Pinion - OEM Replacement Part for Tamping Rammers

The pinion is a critical drive component in the MT-65H rammer's gearbox assembly, transferring power from the centrifugal clutch to the tamper mechanism. This gear component operates within the oil bath lubrication system and must maintain precise tolerances to ensure proper ramming action and prevent premature wear of surrounding drivetrain components.

The MT-65H rammer uses a centrifugal clutch engagement system that activates by increasing engine speed, making the pinion gear essential for reliable power transmission during compaction operations. Regular inspection of the gearbox oil level through the sight glass at the rear of the tamper foot helps protect this component from excessive wear. Signs that pinion replacement may be needed include unusual grinding noises from the gearbox, inconsistent ramming action, or visible wear patterns on gear teeth during routine maintenance.

This pinion is compatible with the following Multiquip rammer models:

• MT-65H
• MT-65HA
