Multiquip 22339 Rear Engine Mount Assembly - OEM Replacement Part

The rear engine mount assembly secures and isolates the Yanmar 4TNV84T diesel engine in ride-on power trowels, absorbing vibration and maintaining proper engine alignment during high-speed finishing operations. This critical mounting component ensures the 55 hp turbocharged diesel engine remains stable under the dynamic loads generated during concrete finishing work, where rotor speeds reach up to 160 rpm and blade tip speeds of 1,924 ft./min.

Failed or worn engine mounts can cause excessive vibration, misalignment of drive components, and premature wear on hydraulic and mechanical systems. Signs of mount failure include increased vibration at the operator station, unusual engine movement during startup or speed changes, and visible deterioration of the mounting hardware. Given the operating weight of 2,165 lbs and the high-output engine performance requirements, maintaining secure engine mounting is essential for safe operation and equipment longevity.

This rear engine mount assembly is specifically engineered for the demanding environment of diesel-powered ride-on trowels, designed to withstand the combination of engine torque, machine weight, and continuous vibration exposure during extended finishing operations.
