FAQ

Q1: Is this cylinder head a direct bolt-on for my Mitsubishi 6D31T forklift engine?

Yes, this is a direct replacement part. It is designed to the same specifications as the original Mitsubishi head. However, we strongly recommend checking your current head’s part number (ME081541, ME997159, or ME997168) to confirm 100% compatibility before installation.

Q2: Does the cylinder head come with valves, springs, and seals installed?

This listing is for the cylinder head casting. It typically includes pre-installed valve guides and seats. Valves, springs, retainers, and seals (valve stem seals) are generally not included and should be transferred from your old head or purchased separately as a valve train kit.

Q3: What is the recommended procedure before installing this new cylinder head?

Before installation, ensure the engine block deck surface is perfectly clean and flat. Use a new head gasket and head bolts (torque-to-yield bolts are recommended for the 6D31). Lubricate the cylinder head bolts and tighten them in the correct sequence and torque specifications as per the Mitsubishi service manual. Always check valve clearance after installation.
