FAQ

Q1: Will this cylinder head fit my excavator model?
A: This cylinder head is specifically designed for the Mitsubishi 4D34 engine. To confirm fitment, please check your engine’s model plate. If your machine uses a 4D34 engine (e.g., in certain Mitsubishi excavators), it is compatible. For absolute certainty, provide your machine’s chassis or serial number to our sales team for cross-verification.

Q2: Are the valve seats and guides pre-installed?
A: This is a complete cylinder head assembly. The valve seats and guides are fully installed and machined to final specifications. The head is ready for installation after transferring your existing valves, springs, and retainers (or using new ones). No additional machining is required.

Q3: What maintenance is recommended after installation?
A: After installation, it is critical to follow the engine manufacturer’s torque specifications and tightening sequence for head bolts. We recommend using new head gaskets and bolts. After initial startup, re-torque the head bolts as per the service manual (typically after the first heat cycle). Regularly check coolant and oil levels post-installation to ensure proper sealing.
