Multiquip 040006307 Bearing 6307 Ball - OEM Replacement Part for Tamping Rammers

The 6307 ball bearing provides critical rotating support within the drive system of Mikasa MT-86D and MT-86D2 tamping rammers. This precision bearing enables smooth power transmission from the engine through the centrifugal clutch system that converts circular motion into the powerful consecutive impact force these diesel rammers deliver to soil surfaces.

Designed for the demanding conditions of soil compaction work including road construction, embankments, reservoir preparation, and utility backfilling applications, this bearing must withstand continuous high-impact operation. Regular inspection of rotating components is essential to maintain the optimum compacting performance these rammers are known for. Signs that bearing replacement may be needed include unusual noise during operation, increased vibration, or reduced impact efficiency.

The MT-86D series tamping rammers use an oil bath lubrication system, and proper maintenance of rotating bearings directly affects the longevity of the gearbox and spring cylinder assembly. Always verify oil levels through the sight glass at the rear of the tamper foot before operation.

Compatible with the following Mikasa tamping rammer models:

• MT-86D
• MT-86D2
