SKF HM89411 Transfer Case Idler Shaft Race

SKF HM89411 is a transfer case idler shaft race built for smooth bearing operation in drivetrain service. With a 3.000 in outside diameter and 1.156 in width, this race is sized for precise support in transfer case bearing assemblies used across applications such as Chevrolet and GMC truck drivetrains.

Key Features

• Transfer case idler shaft race for bearing service
• 3.000 in outside diameter for proper race seating
• 1.156 in width for dimensional match-up
• Logarithmic roller raceway profile for smooth rolling contact
• Fine surface finish to reduce noise during operation
• SKF HM89411 engineered to meet or exceed common application requirements

Detailed Description

The SKF HM89411 race is manufactured for transfer case bearing assemblies where consistent roller guidance and stable support matter. SKF uses a tapered roller race design with a smooth raceway profile to promote quiet operation and long service life. For drivetrain repairs on Chevrolet and GMC models, this part number HM89411 provides a direct replacement option when the original race is worn, scored, or out of specification.

This part cross-references 3N4967 and 15586568 for the same application.

What It Helps Fix

• Transfer case noise caused by worn race surfaces
• Rough or uneven bearing rotation in the idler shaft area
• Excessive play from damaged bearing race dimensions
• Metal wear marks from pitting or scoring inside the transfer case
• Drivetrain vibration related to bearing support wear

Installation Notes and Tips

Inspect the mating bearing, shaft, and transfer case bore before installation. Press the race into place using proper bearing service tools to avoid distortion or surface damage. Confirm the 3.000 in outside diameter and 1.156 in width match the original specification before assembly. For Chevrolet and GMC transfer case repairs, verify the original part number HM89411 against the removed component.

Quality Assurance

SKF has more than 100 years of engineering and manufacturing experience in bearing technology. HM89411 is produced to high quality standards for durable service in drivetrain applications.
