OEM Cross-Reference
This valve seat set directly replaces the following original equipment manufacturer part numbers:
Mitsubishi: 22114-42001 (Intake Valve Seat)
Mitsubishi: 22115-42001 (Exhaust Valve Seat)
These numbers correspond to the valve seat components used in Mitsubishi 4D56 series diesel engines. Always verify your existing part numbers before ordering to ensure correct application.
Compatibility
This valve seat set is specifically designed for the Mitsubishi 4D56 diesel engine platform. The 4D56 is a 2.5L inline-4 diesel engine commonly used in:
Construction equipment (excavators, compactors, loaders)
Industrial machinery and generators
Agricultural tractors and implements
Marine propulsion and auxiliary engines
Material handling equipment (forklifts, telehandlers)
Note: Fitment is based on engine model identification. Always confirm your specific engine serial number and valve dimensions before installation.

FAQ
Q1: How do I confirm these valve seats fit my specific engine? Verify your existing valve seat part numbers match 22114-42001 and/or 22115-42001. For engines without visible part numbers, measure the outer diameter, inner diameter, and thickness of your current valve seats and compare with OEM specifications for the 4D56 engine. We recommend consulting your engine service manual for exact dimensions.
Q2: What is the recommended installation procedure for these valve seats? Installation requires specialized valve seat cutting and pressing equipment. The cylinder head must be thoroughly cleaned and the valve seat bore must be within specification. Valve seats should be pressed or shrunk-fitted (heat the head, cool the seat) to the correct depth. After installation, valve seats must be cut to the proper angle (typically 45° for intake and exhaust) and lapped to ensure perfect sealing with the valve face.
Q3: How long do these valve seats typically last in heavy-duty applications? Service life depends on operating conditions, fuel quality, maintenance intervals, and valve adjustment. In well-maintained 4D56 engines used in construction or genset applications, these valve seats typically last 3,000-6,000 operating hours before requiring inspection. Regular valve clearance adjustments and using clean fuel with proper lubricity significantly extend service life. We recommend replacing valve seats whenever the cylinder head is overhauled.
