Yanmar YM2202 | YM2220 head gasket – 3T84 engine | Komatsu PC20 – PC38 | Takeuchi TB025

Description

Premium head gasket for the Yanmar 3T84 three-cylinder diesel engine — one of the most widely used engines in compact tractors and mini excavators. Komatsu builds this engine under its own designation as the 3D84-1, so this gasket fits directly on a long line of Komatsu PC excavators. The gasket is a 1-to-1 OEM replacement — gas- and liquid-tight seal between cylinder head and block.

✔️ Snel Parts Premium quality — gas- and liquid-tight seal

Pro tip from experience: when replacing a head gasket, always check the cylinder head bolts — stretched bolts will cause immediate leakage on the new gasket.
