Head gasket Mitsubishi K3B | Iseki TU140 | TU145 | TU1500 | TX155 | TX1510 | TX2160 | Mitsubishi D1550 | Satoh | Bolens | Pel Job

Description

New head gasket for the Mitsubishi K3B, the three-cylinder diesel engine from the Iseki TU140 to TU1500 and the TX-series, the Mitsubishi D1550 and MT1401, and a significant number of mini excavators and generators. The gasket creates a seal between the cylinder head and engine block, keeping compression, coolant, and oil strictly separated.

✔️ Bore 68 mm — exclusively for the K3B, not interchangeable with K3A, K3C, or K3D
✔️ Direct 1-to-1 replacement for Mitsubishi MM408452 / Iseki 5650-040-845-20
✔️ Also available as part of our complete gasket set for the K3B

Technical specifications:

• Engine: Mitsubishi K3B, 3 inline cylinders, water-cooled, indirect injection
• Bore x stroke: 68 x 78 mm
• Displacement: 849 cc
• Variants: K3B, K3B-31DS, K3B-31NSA

Please note: the K3A, K3B, K3C, and K3D look very similar externally, but each has a different bore (65 – 68 – 70 – 73 mm). Check the engine type on the nameplate before ordering; a head gasket from an adjacent type will not fit.
