Honda 91051-VP8-003 Radial Ball Bearing (609LL)

The Honda 91051-VP8-003 Radial Ball Bearing (609LL) is a genuine OEM component designed for UMC425 and UMC435 trimmers. As a direct Honda OEM part, it is manufactured to the same specifications as the original, ensuring an exact fit within the drivetrain of these multi-tool units. Confirm your trimmer's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and this bearing is listed for specific production ranges.

Key Features

• Genuine OEM Ball Bearing — sourced directly from Honda, this bearing meets the same tolerances as the original installed at the factory, maintaining the smooth, low-friction rotation these trimmers depend on
• Correct 609LL Specification — the (609LL) designation identifies the exact bearing size and seal type; matching this to your unit's parts diagram ensures the right component goes in every time
• Fits UMC425 and UMC435 Trimmers — listed for both Honda UMC-series multi-tool trimmers; check your serial number against the compatibility table to confirm applicability to your unit
• Smooth Operation Restored — a worn or failed bearing causes increased friction, vibration, and noise in the rotating assembly; replacing it with this OEM part brings the trimmer back to proper operating condition

A radial ball bearing supports a rotating shaft by carrying the load through a ring of precision balls seated between an inner and outer race. In the UMC425 and UMC435 trimmers, this bearing keeps the shaft turning freely and concentrically, reducing friction and absorbing radial forces generated during operation. When the bearing wears out or its seals fail, drag increases, heat builds up, and the shaft can develop play — all of which degrade cutting performance and accelerate wear on surrounding components.
