Detailed Description

InMotion RB6201-ZZ is a generator commutator end bearing intended for alternator rebuild and repair work. Its compact dimensions and ball-bearing construction make it a direct-service component for maintaining stable shaft support in charging-system assemblies. The RB6201-ZZ is listed for a broad range of older import vehicles, including Audi S6, Audi 100, and Toyota Corolla applications with the specified alternator amperage ratings.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems It Can Address

• Alternator bearing noise during engine operation
• Rough or inconsistent generator shaft rotation
• Excess friction inside the charging system
• Wear-related alternator instability
• Service needs on rebuildable alternators for Audi, Toyota, and Mitsubishi platforms

Installation Notes and Tips

• Verify alternator amperage and bearing dimensions before installation.
• Inspect the commutator end housing, shaft, and adjacent bearing surfaces for wear or scoring.
• Press the bearing in evenly to avoid damage to the race or seal surfaces.
• Confirm the alternator spins freely after assembly and before returning the vehicle to service.
• Compatible vehicle examples include Fits 1995-1997 Audi S6, N/A, with 110 Amp Alternator; Fits 1978-1987 Toyota Corolla, N/A, with 50, 55 Amp Alternator; and Fits 1983-1986 Mitsubishi Montero, N/A, with 45, 50 Amp Alternator.
