The Multiquip 451423230 Shifter Shaft Collar R400G/D is a genuine OEM component designed for the R-400G roller. Sourced directly from Multiquip, this collar matches the exact specifications of the original part — ensuring correct shaft engagement and reliable gear shifting performance. Confirmed fitment for the R-400G series makes this a straightforward, confidence-inspiring replacement for operators and service technicians alike.
Key Features
- Genuine OEM Collar Integrity — Machined to the same dimensional tolerances as the original, ensuring proper collar-to-shaft contact and consistent shifter actuation.
- Direct Drop-In Replacement — Mounts to the shifter shaft using the original hardware and connection points, requiring no rework of surrounding components.
- Confirmed R-400G Fitment — Engineered specifically for the Multiquip R-400G roller; use part number 451423230 to verify compatibility before ordering.
- Maintains Precise Gear Engagement — A correctly fitted shaft collar holds positional accuracy on the shifter assembly, preventing slippage or misalignment that can cause erratic or failed gear selection.
- Operational Safety Consideration — A worn or loose shifter shaft collar can compromise transmission control on a ride-on roller; replacing it promptly keeps drive response predictable and safe for the operator.
The shifter shaft collar is a precision retention component that locks the shifter shaft in its correct axial position within the transmission or drive assembly. It works in conjunction with the shifter mechanism to ensure clean, positive gear engagement — when the collar wears, cracks, or loses its grip on the shaft, the shifter can slip out of position, leading to missed gear changes, drive loss, or unpredictable machine behavior. Replacing a failed collar restores the mechanical reference point that the entire shift linkage depends on.
