J 901306 BUSH - CAM SHAFT ( GENUINE )

The Camshaft Bush is a precision engine internal bearing component designed for use in the engine block camshaft support system of CASE 580 E, K, L, and M series backhoe loaders.

Installed in the camshaft bore of the engine block, this bush provides a smooth, low-friction bearing surface that supports camshaft rotation while maintaining correct alignment and oil clearance. Proper camshaft bush condition is essential for accurate valve timing, stable engine operation, and long engine service life.

As a CNH Genuine Original part, this camshaft bush is manufactured to strict OEM specifications for material quality, dimensional accuracy, and wear resistance. It is commonly replaced during engine overhaul, camshaft replacement, or engine block reconditioning, especially when excessive wear, noise, or oil pressure issues are present.

Correct installation helps prevent abnormal camshaft wear, lubrication loss, timing irregularities, and premature engine damage.

Key Functions:

• Supports and aligns the camshaft within the engine block

• Provides a durable bearing surface for smooth rotation

• Maintains correct oil clearance and lubrication flow

• Ensures accurate valve timing and engine reliability
