Perkins 02202950 Rocker Shaft Assembly

The 02/202950 rocker shaft assembly is a critical valve train component designed for Perkins 1104C and 1104D 4.4-liter four-cylinder diesel engines. It integrates the rocker shaft, rocker arms, brackets, and adjustment screws into a single service unit. Manufactured from forged alloy steel with induction-hardened contact surfaces, the assembly withstands high cyclic loads and thermal stress in heavy-duty construction equipment applications. The shaft features precision-machined journals for consistent lubrication clearance. Rocker arms are phosphate-coated for corrosion resistance and break-in protection. This assembly replaces Perkins OEM part numbers 02/202950, 02-202950, and 02202950. It is engineered for direct installation on JCB backhoe loaders (3CX, 4CX, 214-2, 217-4), wheel loaders (411, 416, 407ZX, 408ZX, 409ZX), and telehandlers (520-50, 525-50, 535-125, 540 series) equipped with the specified Perkins power units.
