Multiquip 2843170121 Camshaft CP - OEM Replacement Part for Rammers

The camshaft controls valve timing and operation in the Robin EH09 series engine, directly affecting compression, power output, and fuel efficiency in your tamping rammer. This genuine OEM camshaft is engineered for Tier 2 compliant MTR40F series engines, designed to maintain the factory-specified 2.4 HP output at 3,600 RPM and deliver the 600-695 blows per minute impact rate required for optimal compaction performance.

In tamping rammer applications, camshaft wear manifests as reduced engine power, irregular jumping patterns, or failure to maintain the proper operating speed. The MT55F and MTR40F models rely on consistent engine speed to engage the centrifugal clutch and generate the 1,650-2,250 lbs. impact force needed for effective soil compaction. A worn camshaft compromises valve lift and timing, reducing the 2.4 HP output of the air-cooled 4-stroke OHV engine and preventing the rammer from achieving its rated 36 ft./min travel speed.

Compatible with the following Multiquip rammer models:

• MT55F
• MTR40F
• MTR40SF
