InMotion WT30205 Manual Transmission Countershaft Bearing

Manual Transmission Countershaft Bearing Overview

The InMotion WT30205 manual transmission countershaft bearing is built for manual gearboxes that need stable rotation, reduced friction, and consistent support under load. With cylindrical construction and taper-bearing geometry, it serves a wide range of transmission applications, including Mitsubishi KM-series units used in Ford Ranger, Mitsubishi Mighty Max, and Dodge Ram 50 drivetrains.

Use WT30205 when servicing a manual transmission that calls for a countershaft bearing with a 25 mm inside diameter, 52 mm outside diameter, and 16.3 mm set width. The compact bearing design supports smooth operation in center, front, front outer, and upper positions depending on the transmission application.

Detailed Product Description

InMotion WT30205 is a manual transmission countershaft bearing intended for service work on a broad range of older import and compact truck applications. The listed dimensions and bearing profile make it suitable for transmission rebuilds where precise shaft support is critical. This part number WT30205 appears in applications for Mitsubishi KM132, KM145, FM155, and FM146 transmission variants, along with select Toyota Land Cruiser manual steering and upper-position uses.

Compatible vehicle coverage includes Mitsubishi Mighty Max, Dodge Ram 50, Ford Ranger, Mazda B2200, Mazda B2600, Ford Bronco II, Mitsubishi Montero, Chrysler Conquest, Dodge Raider, Plymouth Conquest, and Toyota Land Cruiser. For technicians and DIY rebuilders, WT30205 provides a direct-fit bearing solution where the original countershaft bearing has worn, become noisy, or lost smooth operation.

What This Bearing Helps Solve

• Transmission noise caused by worn countershaft bearings
• Excessive shaft play in manual gearboxes
• Rough shifting linked to bearing wear or drag
• Heat and friction buildup inside the transmission case
• Loss of rotational stability in rebuild or repair work

Installation Notes and Tips

Confirm the transmission code before ordering, since WT30205 is listed across multiple Mitsubishi-based manual transmissions with different positions and notes. Match the inside diameter, outside diameter, and set width to the original bearing specification during teardown. Clean the bearing seat, inspect the shaft and race surfaces, and verify the position callout for the vehicle and transmission combination before assembly.
