Pinion Bushing Line Reamer Tool - JIMS USA

The JIMS USA 94805-57 Pinion Bushing Line Reamer Tool is designed for precise sizing and alignment of pinion bushings during gearcase and transmission service. Built for professional use, it helps ensure correct pinion shaft fit, smooth rotation, and long-term reliability in high-load applications.

Key Features

• Precision line reaming for accurate sizing and alignment of pinion bushings relative to the bore and shaft
• Professional-grade construction from JIMS USA, engineered to hold tolerance under repeated shop use
• Consistent bore finish helps reduce pinion shaft drag, premature wear, and noise
• Improves service accuracy compared to makeshift or generic reamers, reducing rework and comebacks
• Designed for drivetrain work where maintaining correct pinion geometry is critical to gear life and performance

Applications

The JIMS 94805-57 Pinion Bushing Line Reamer is intended for professional technicians and engine/transmission builders servicing pinion bushings in gearcases and similar housings. Typical uses include:

• Reaming new or replacement pinion bushings to final size after installation
• Correcting slight misalignment between bushing and bore to improve shaft support
• Preparing rebuilt gearcases to restore correct pinion shaft fit and running clearance
• Use in performance, restoration, and high-mileage service where pinion accuracy is critical

Always verify fitment and service procedures against the appropriate factory or JIMS service manual for the specific model you are working on.
