As a direct Honda OEM part, it is manufactured to the same specifications as the original, ensuring correct fit without alteration or adaptation. Honda supersedes parts at serial breaks, so confirm your unit's serial number against the fitment table before ordering to be certain part number 91557-764-L31 is the right listing for your machine. The 3/4 qualifier identifies the specific variant — verify it matches your application before purchase.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this Taper Lock Bush Assembly meets the same standards as the part originally installed on the MM60 compact tractor.
- Variant Accuracy — the (3/4) designation identifies this as a specific size variant; match it carefully to your unit to ensure correct fitment.
- Serial Number Verification Advised — Honda updates part fitment at production serial breaks, so cross-reference your machine's serial number with the compatibility table before finalizing your order.
- Secure Locking Function — a correctly fitted taper lock bush grips the shaft with even radial clamping force; a worn or failed bush allows slippage that degrades power transfer and accelerates wear on mating components.
A taper lock bush is a split, tapered sleeve that clamps onto a shaft when fastened into a matching tapered bore on a hub or sprocket. As the fasteners are tightened, the taper draws the sleeve inward, creating firm, concentric clamping around the shaft without the need for keyways alone. This design transmits torque effectively and allows for straightforward removal during service. When the bush wears or loosens, the resulting shaft slippage causes uneven power transmission and can damage both the shaft and the hub it seats in.
