J 901306 BUSH - CAM SHAFT DCEC

The Camshaft Bush is a precision engine internal bearing component used in the engine block camshaft support system of CASE 580 E, K, L, and M series backhoe loaders equipped with Cummins diesel engines.

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

As a DCEC Original Cummins component, this camshaft bush is manufactured to meet Cummins engine specifications for material strength, dimensional accuracy, and wear resistance. It is commonly replaced during engine overhaul, camshaft replacement, or engine block reconditioning, especially when wear, noise, or oil pressure issues are detected.

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 low-friction bearing surface for smooth rotation

• Maintains correct oil clearance and lubrication flow

• Ensures accurate valve timing and reliable engine performance
