The Multiquip 21-1200 Square Key 3/16" x 40mm is a genuine OEM component designed for TB11E and TB11G power buggies. Sourced directly from Multiquip, this key delivers the exact dimensions and material grade required to maintain a secure, torque-transferring fit between shaft and hub. It is a direct replacement for worn or damaged keys on TB11E and TB11G units, with no rework or fitting required at installation.
Key Features
- Genuine OEM Dimensional Accuracy — Precision-cut to exact 3/16" x 40mm specification, ensuring full contact across the keyway for proper torque transmission without slop or fretting.
- Direct Drop-In Replacement — Matches the original keyway geometry on TB11E and TB11G power buggy driveline components, seating cleanly without filing or shimming.
- Compatible with TB11E and TB11G Power Buggies — Confirmed fitment for both the electric-start and gasoline-powered variants of the TB11 series.
- Maintains Drive Engagement — A correctly fitted square key locks rotating components in phase, preventing slippage under load that would otherwise cause erratic drive behavior or component damage.
- Durable Material Construction — Manufactured to OEM hardness and shear-strength standards, resisting the cyclic loading and impact stresses common in power buggy operation.
A square key is a small but critical drivetrain component that sits in a machined slot — the keyway — between a shaft and a mating hub, pulley, or sprocket. It prevents relative rotation between the two parts, transferring torque from the power source to the driven component. When a key shears or wears, the shaft spins freely inside the hub, causing a complete loss of drive to that assembly. Replacing a damaged key promptly restores full drivetrain integrity and prevents secondary wear to the keyway itself.
