Multiquip 2842030101 Crankshaft CP - OEM Replacement Part for Rammers

The crankshaft is the core rotating component that converts circular motion into the powerful vertical impact force required for soil compaction in Multiquip tamping rammers. This genuine OEM crankshaft is engineered specifically for MTR40F Tier 2 engine configurations, maintaining the precise balance and tolerances needed to deliver 600-695 blows per minute at optimal performance levels.

In tamping rammer operation, the crankshaft works with the centrifugal clutch system to transfer engine power through the gearbox and spring cylinder assembly, creating the impact force that compacts soil. Common symptoms indicating crankshaft failure include erratic jumping, excessive vibration, loss of impact force, or complete operational failure. The MT55F rammer develops 1,650-2,250 lbs. per blow of impact force—performance that depends entirely on crankshaft integrity.

This crankshaft is designed for air-cooled 4-stroke single cylinder OHV horizontal shaft gasoline engines operating at 3,600 RPM. Proper installation requires adherence to factory torque specifications and alignment procedures outlined in the Multiquip service manual.

Compatible with the following Multiquip rammer models:

• MT55F
• MTR40F
• MTR40SF
