The Multiquip 21-1201 Square Key 3/16" x 25 MM is a genuine OEM replacement component designed for TB12SE and TB12PE power buggies. Sourced directly from Multiquip, this key meets the exact dimensional and material specifications required for proper drivetrain engagement on these machines. If you are servicing a TB12SE or TB12PE and need a confirmed OEM fit, the 21-1201 is the correct part for the job.
Key Features
- OEM-Spec Dimensional Accuracy — Manufactured to the exact 3/16" x 25 MM specification required for correct shaft-to-hub engagement, preventing slippage and ensuring positive power transfer.
- Drop-In Replacement — Matches the original keyway geometry on TB12SE and TB12PE power buggy driveline components, seating flush without grinding or modification.
- Confirmed Fitment — Directly compatible with Multiquip TB12SE and TB12PE power buggies; part number 21-1201 cross-references the original OEM specification.
- Drive Integrity — A correctly seated square key locks rotating components to their shafts, maintaining torque transmission and preventing premature wear on mating keyways.
- Genuine Multiquip OEM Part — Supplied by an authorized Multiquip dealer, this is not a generic hardware substitute — it is the same key supplied in original production.
A square key is a small but critical drivetrain component that locks a rotating shaft to a hub, sprocket, pulley, or gear, ensuring they turn together as a single unit. When the key shears, deforms, or goes missing, the driven component spins freely on the shaft, causing a complete loss of power transmission to that driveline point. Replacing a worn or failed key promptly with a correctly sized OEM piece restores full torque transfer and prevents secondary damage to the keyway slots on both the shaft and the mating hub.
