Product Details

The Honda OEM K-Series Manual Transmission Countershaft Ball Bearing is a genuine factory replacement designed to provide smooth rotation, precise shaft support, and dependable performance in compatible Honda and Acura manual transmissions.

Manufactured to Honda's original equipment specifications, this precision-engineered bearing measures 30mm x 72mm x 17mm and is designed for the countershaft assembly in select K-Series manual transmissions.

Commonly used in Honda and Acura vehicles equipped with compatible 5-speed and 6-speed manual transmissions, this genuine Honda bearing is an excellent replacement for worn or damaged factory transmission components.

The countershaft plays an important role in transferring power through the manual transmission. Its bearings support the rotating shaft, reduce friction, and help maintain proper alignment between the transmission's internal gears.

Over time, transmission bearings can develop wear from high mileage, contaminated transmission fluid, excessive drivetrain loads, or performance driving. A worn countershaft bearing may contribute to transmission whining, vibration, abnormal shaft movement, or accelerated wear of surrounding transmission components.

Whether you're rebuilding a K-Series manual transmission, refreshing a high-mileage gearbox, or preparing a Honda drivetrain for a performance build, this genuine Honda OEM Countershaft Ball Bearing provides factory-correct dimensions and dependable construction.

Common Reasons for Replacement

Manual transmission bearings should be inspected whenever the gearbox is disassembled for maintenance or rebuilding.

Transmission whining or abnormal bearing noise
Rough or noisy countershaft rotation
Excessive transmission shaft movement
Worn or damaged bearing races
Pitting or deterioration of bearing surfaces
Contaminated or insufficient transmission fluid
High-mileage transmission rebuilding
Gear or synchronizer replacement
K-Series transmission restoration
Performance transmission assembly
Replacing a worn countershaft bearing helps restore proper shaft support and may prevent additional damage to surrounding transmission components.

Installation Notes

Proper installation is essential for maintaining correct transmission shaft alignment and bearing performance.
Before installation, inspect the transmission countershaft, bearing seating surfaces, and transmission housing for wear or damage.
Confirm that the replacement bearing matches the original component's dimensions and specifications.
Use appropriate bearing removal and installation equipment to prevent damage to the bearing races, shaft, or transmission housing.
Important: Apply installation force only to the appropriate bearing race according to the factory service procedure. Improper pressing techniques can damage a new bearing before the transmission is reassembled.
Inspect related transmission bearings, synchronizers, gears, and shaft components while the gearbox is disassembled.
Follow the Honda factory service manual for the correct installation procedures, transmission clearances, and reassembly specifications.
After reassembly, refill the transmission with the manufacturer-specified manual transmission fluid and verify proper operation.

Includes one genuine Honda OEM Countershaft Ball Bearing (30x72x17mm). Transmission shafts, gears, synchronizers, seals, and additional bearings are sold separately unless otherwise specified.

For Honda and Acura enthusiasts rebuilding a K-Series manual transmission, restoring a factory drivetrain, or preparing a performance gearbox, this genuine Honda OEM Countershaft Ball Bearing delivers factory-correct dimensions, precise shaft support, and dependable transmission performance.
