Multiquip 2522250120 Connecting Rod Assembly - OEM Replacement Part for Rammers

The connecting rod assembly is a critical internal engine component that converts the reciprocating motion of the piston into rotational force, transferring power to the crankshaft in your tamping rammer. This genuine OEM part is engineered specifically for the Robin EH12-2D engine, which produces 3.5 hp at 3,600 rpm and powers the MT74FAF to deliver 640-680 impacts per minute with 3,100 lbs of compacting force.

The MT74FAF uses an oil bath lubrication system with 10W30 motor oil to protect internal engine components including the connecting rod assembly. Regular monitoring of the oil level sight glass at the rear of the tamper foot is essential to prevent premature wear or catastrophic failure of this component. Signs that this assembly may need replacement include unusual knocking sounds from the engine, loss of power output, excessive vibration beyond normal tamping operation, or visible damage during routine maintenance inspections.

This connecting rod assembly is designed to handle the demanding conditions of soil compaction work, including road construction, embankment building, and backfilling applications where the rammer operates continuously at 4,000 rpm.

Compatible with the following model:

• MT74FAF Tamping Rammer
