Multiquip 371447640 Drum Clutch - OEM Replacement Part for Tamping Rammers

The drum clutch is a critical component in the automatic centrifugal clutch system that transmits engine power to the ramming mechanism at the proper operating speed. This OEM part engages when engine speed reaches 3,300 rpm to deliver the 700 blows per minute impact force required for effective soil compaction. When the clutch slips or fails, you'll experience non-uniform amplitude or complete loss of striking action even though the engine rotates normally.

According to Multiquip service documentation, proper clutch engagement is essential for the MT-76D2's operational characteristics. The throttle lever must be moved quickly from IDLE to OPERATION position to prevent clutch damage. Operating above the recommended 3,300 rpm creates unwanted resonance rather than effective tamping and accelerates clutch wear. The clutch works in conjunction with the oil bath lubrication system (1.7 pt capacity, 10W-30 motor oil) and spiral spring to convert circular motion into the 3,600 lbs. per blow impact force at the rammer foot.

This drum clutch is compatible with the following Multiquip tamping rammer models:

• MT-76D
• MT-76D2
• MT-86D
• MT-86D2
