Multiquip 506442930 Cap - OEM Replacement Part for Vibratory Rollers

This cap is a genuine OEM component designed for Multiquip MRH601DS and MRH800GS vibratory rollers. Based on the component diagram reference (item #15), this is the coolant radiator cap used to service and fill the radiator with coolant on these walk-behind compaction machines. The radiator cap maintains proper cooling system pressure and provides access for coolant fills during routine maintenance of the Kubota EA330-E3 diesel engine.

The MRH601DS is a 1,215 lb double drum vibratory roller with 2,428 lbf centrifugal force, operating at 3,300 vpm (55 Hz) vibration frequency. Proper cooling system maintenance is critical for these machines, which feature a 13.98-inch drum diameter, 25.59-inch compaction width, and can handle grades up to 35% (20°). Regular inspection and replacement of cooling system components like this radiator cap helps prevent engine overheating during demanding compaction operations.

Compatible with the following Multiquip vibratory roller models:

• MRH601DS
• MRH800GS
