Key Features
- Genuine OEM Material Spec — machined to the precise dimensional tolerances required for a square drive key, ensuring full torque transfer without slippage or deformation under load.
- Drop-In Shaft Fit — sized to seat directly into the keyway on the CRT48I drivetrain shaft, aligning mating components without modification to the shaft or hub.
- CRT48I Power Trowel Compatibility — purpose-built for the CRT48I ride-on trowel, so you can order with confidence knowing this key matches the machine's original design.
- Restored Drive Engagement — a worn or sheared square key causes the driven component to slip on the shaft, losing rotational force; replacing it with this OEM key restores positive drive engagement immediately.
A square key is a small but critical drivetrain component that sits in a machined slot — the keyway — between a rotating shaft and a mating hub or gear. Its job is to lock those two parts together so torque is transferred from one to the other without relative slipping. When a square key shears or wears down, the driven component loses its mechanical connection to the shaft, resulting in loss of power transmission and potential damage to the keyway itself. Replacing a failed key promptly with the correct OEM part protects the surrounding shaft and hub from further wear.
