Multiquip 91005KS4003 Radial Ball Bearing - OEM Replacement Part

This radial ball bearing is a critical rotating component in Multiquip tamping rammer power transmission systems, supporting the engine's power transfer through the centrifugal clutch mechanism. The MT77HFR rammer series uses a circular motion conversion system to generate impact force at the tamper foot, and this bearing ensures smooth, consistent power transmission from the Honda GXR120RT engine through the drive assembly.

The bearing operates within the oil bath lubrication system that characterizes these rammer models. Regular inspection of bearing condition should coincide with oil level checks through the sight glass at the rear of the tamper foot. Failed or worn bearings typically present as increased vibration, unusual noise during operation, or inconsistent impact force delivery. Given the tremendous compacting forces these rammers generate, maintaining bearing integrity is essential for both performance and operator safety.

Compatible with the following Multiquip rammer models:

• MT77HFR
• MTX70HDR
• MTX80HDR
