6D34 Valve Seat ME013297 ME013188 for Mitsubishi Engine Parts Excavator Truck Loader

Product Details

Product Overview

This premium aftermarket valve seat, identified by part numbers ME013297 and ME013188, is engineered specifically for the Mitsubishi 6D34 diesel engine. As a critical component of the cylinder head, this valve seat ensures a proper seal for intake and exhaust valves, directly impacting engine compression, fuel efficiency, and overall performance.

Manufactured to original equipment (OEM) size specifications, this component is commonly used in a variety of heavy-duty applications, including excavators, trucks, forklifts, bulldozers, buses, and loaders. It is a direct replacement part designed to restore the cylinder head to factory specifications, making it an essential item for engine rebuilders and maintenance professionals.

Key Features & Benefits

• OEM Specification Fitment: Machined to precise OEM dimensions (ME013297 / ME013188) for a direct, drop-in replacement, eliminating the need for modifications.
• High Durability Material: Constructed from wear-resistant alloy material to withstand high temperatures and pressures, providing a long service life in demanding diesel applications.
• Improved Engine Compression: A precise valve-to-seat interface ensures optimal sealing, maximizing cylinder compression for better power output and fuel economy.
• Reliable Valve Cooling: Proper thermal transfer from the valve head to the cylinder head helps prevent valve burning and premature failure.
• Cost-Effective Solution: Offers a significant price advantage over genuine OEM parts while maintaining the quality required for professional engine rebuilds.
• Rigorous Quality Control: Each valve seat undergoes dimensional inspection and material verification to ensure consistent quality across every batch.

FAQ

Q: How do I know if this valve seat fits my specific 6D34 engine head?
A: This valve seat is manufactured to standard OEM size for the 6D34. However, cylinder heads may have been reconditioned with oversized seats in the past. We recommend measuring the valve seat counterbore diameter (OD of the old seat) and the valve head diameter to confirm compatibility. If your engine requires an oversized seat, please contact us with your specific dimensions.

Q: Do I need to machine the valve seat after installation?
A: Yes. While the outer diameter (OD) is pre-machined for a press fit, the inner seat face (where the valve contacts) must be cut with a valve seat cutter or grinder to match the valve face angle (typically 45° or 30°). This ensures proper concentricity and a gas-tight seal. We recommend having this done by a qualified engine machinist.

Q: What is the recommended installation procedure for this valve seat?
A: Installation typically involves heating the cylinder head to 150-200°C (302-392°F) in an oven or using a hot plate, then pressing the chilled valve seat into the counterbore. Never strike the seat directly with a hammer. Use a suitable driver tool and an arbor press to ensure the seat is fully seated and flush with the head surface. Allow the head to cool slowly to avoid cracking.
