Multiquip 371334400 Crank Gear - OEM Replacement Part for Tamping Rammers

The crank gear is a critical power transmission component in the Mikasa MT-76D tamping rammer's gearbox assembly, converting circular motion into the vertical impact force that creates the 3,600 lbs. per blow compacting power at 700 blows per minute. This precision-machined gear works in conjunction with the centrifugal clutch system to deliver consistent tamping action when the throttle lever moves from IDLE to OPERATION position at the specified 3,300 rpm engine speed.

Located within the oil bath lubrication system of the rammer gearbox, this crank gear requires proper lubrication through the #10W-30 motor oil system (approximately 1.7 pt. capacity). Common symptoms indicating crank gear wear or failure include non-uniform amplitude during operation, inconsistent striking action even when the engine rotates properly, or unusual noise from the spring cylinder assembly. Regular inspection through the oil level sight glass at the rear of the tamper foot helps identify potential lubrication issues that can accelerate gear wear.

Compatible with the following Multiquip tamping rammer models:

• MT-76D2
