The Multiquip M5K0404060 Key for Gear No. 3 is a genuine OEM component designed for the MB25H Rebar Bender. This small but critical drive key ensures Gear No. 3 is correctly locked to its shaft, maintaining proper power transmission through the bending mechanism. Sourced directly from Multiquip, M5K0404060 is the exact part specified for the MB25H and installs without modification into the original gear assembly.
Key Features
- Genuine OEM Specification — Manufactured to the exact material hardness and dimensional tolerances required for reliable gear-to-shaft engagement in the MB25H drivetrain.
- Direct Shaft-to-Gear Lock — Drops into the original keyway slot on Gear No. 3, restoring the positive mechanical connection between gear and shaft as originally assembled.
- MB25H Fitment Confirmed — Verified for the Multiquip MB25H Rebar Bender; use the model code to confirm compatibility before ordering.
- Preserves Bending Torque Delivery — A worn or missing key causes gear slip under load, leading to inconsistent bend angles and potential damage to surrounding drivetrain components; this replacement restores full torque transfer.
- Fast Service Return — Replacing a failed drive key is one of the quickest drivetrain repairs possible; having the correct OEM key on hand gets the MB25H back to bending rebar without extended teardown time.
A gear key is a small, precisely dimensioned piece of metal that fits into a keyway — a machined slot shared between a shaft and a gear — locking the two together so they rotate as a single unit. In a rebar bender like the MB25H, Gear No. 3 is part of the drive train that converts motor power into the controlled rotational force needed to bend steel reinforcing bar to accurate angles. When the key shears, wears, or goes missing, the gear can spin independently on the shaft, causing loss of bending force, erratic operation, or complete failure to drive the bending head. Replacing the key promptly with the correct OEM part restores the mechanical integrity of the gear assembly and protects surrounding components from further wear.
