Product Features & Engineering Advantages
Critical Component for Valve Timing Control
The camshaft controls the opening and closing of valves, regulating the intake of air and fuel and the expulsion of exhaust gases for combustion. Precise valve timing is essential for optimal engine performance, fuel efficiency, and power output in heavy-duty excavator and crane applications.
Premium Alloy Steel Construction
Manufactured from high-grade alloy steel with induction-hardened cam lobes for exceptional wear resistance. The material ensures long-term durability under extreme combustion pressures and temperatures in demanding construction and mining environments.
Induction-Hardened Cam Lobes
Cam lobes are induction-hardened to HRC 55-60, providing superior resistance to wear and pitting even under continuous heavy-load operation. This hardness rating exceeds standard industry requirements for diesel engine camshafts used in heavy equipment.
Precision-Ground Profiles
Each camshaft is CNC ground to exact OEM specifications with precision lobe profiles ensuring accurate valve lift and duration. This optimizes combustion efficiency and power delivery for both naturally aspirated and turbocharged 6D22 engine variants.
Gear Drive Compatibility
Engineered specifically for gear-driven timing systems used in Mitsubishi 6D22 engines. The timing gear mounting surface is precision-machined for perfect alignment and timing accuracy.
Heavy-Duty Industrial Design
Designed to withstand extreme operating conditions in heavy equipment applications. The camshaft endures immense contact stress from valve springs and lifters in these high-load environments.
OEM-Equivalent Performance
Manufactured to meet or exceed original Mitsubishi specifications for the 6D22 engine series. Ensures compatibility with Kato cranes, Kobelco excavators, and other equipment brands using this engine platform.
Upgraded Durability
Manufactured using materials and processes that meet the higher specifications required for turbocharged 6D22T engines, providing increased durability even when installed in naturally aspirated applications.

Installation Note (Technical Reference)
The camshaft is a precision component that requires careful installation. When installing a new camshaft on a Mitsubishi 6D22 engine, follow these critical guidelines:
Always verify correct timing marks alignment - improper timing can cause valve-to-piston contact and severe engine damage.
The timing gear is typically sold separately and must be properly installed onto the new camshaft.
Always inspect the flat tappets when replacing the camshaft. Worn or concave lifter faces will damage new camshaft lobes within hours of operation. Replacing the tappets simultaneously is strongly recommended for proper durability.
Lubricate cam lobes and journals with assembly lube or clean engine oil before installation.
Follow factory torque specifications and tightening sequences for bearing cap bolts.
Rotate engine manually after installation to ensure no binding occurs.
Professional installation is recommended due to the precision required for proper alignment and timing.
Warning: Never operate the engine without verifying proper valve timing after camshaft replacement. Incorrect timing can result in catastrophic engine failure.
