Multiquip 515650 Engine Mount - OEM Replacement Part

The engine mount secures and isolates the Briggs & Stratton DM850D liquid-cooled diesel engine on ride-on compaction rollers, preventing excessive vibration transfer to the frame while maintaining proper alignment of the drive system. This component is critical for protecting the engine from shock loads during high-amplitude compaction operations and ensuring reliable performance of the 23.6 hp powerplant rated at 3,600 rpm.

Engine mounts deteriorate over time due to constant exposure to vibration, hydraulic fluid contact, and thermal cycling during operation. Failed or degraded mounts can cause misalignment of drive components, excessive engine movement, unusual vibration patterns, and potential damage to hydraulic lines or electrical connections. Regular inspection of engine mounts should be performed during routine maintenance intervals, particularly on units operating in demanding asphalt paving and granular soil compaction applications.

This mount is engineered to handle the operational demands of ride-on tandem drum rollers with operating weights up to 3,437 lbs and centrifugal forces exceeding 3,100 lbs at standard compaction speeds. Proper installation ensures the engine remains securely positioned while maintaining the specified ground clearance of 11.5 inches.
