Full gasket set Yanmar 3TNM68 – Stage V successor 3TNV68 | AJ217 combine | IHI 12NXE | Kato 12VXE | Ferris IS2000 | JCB | Linhai LH300

New full gasket set suitable for the Yanmar 3TNM68 three-cylinder diesel engine — the modern Tier 4 Final / EU Stage V successor to the well-known 3TNA68 / 3TNE68 / 3TNV68 engines (same 68 mm bore × 72 mm stroke, indirect injection). This set contains all gaskets, oil seals, and seals required for a complete engine overhaul or major service.

✔️ Complete set — all gaskets, oil seals, and seals for a full overhaul
✔️ Suitable for all 3TNM68 sub-versions (-ALH, -ASA, -HA, -HDW, -HGE, -AFS, -GHFCG, -GGEP)
✔️ Includes head gasket (OEM 119125-01330) and front + rear crankshaft seals

Kit Contents:

• Cylinder Head Gasket
• Valve cover gasket
• Valve stem seals
• Intake manifold gasket
• Exhaust manifold gasket
• Sump gasket (oil pan gasket)
• Timing cover gasket
• Water pump gasket
• Thermostat housing gasket
• Crankshaft seals (front + rear)
• Various smaller gaskets, copper washers, and O-rings

Mechanic’s tip: always replace all gaskets during an overhaul to prevent leaks and loss of compression after the rebuild. Don’t forget the valve stem seals — these often harden and cause blue smoke.

Please note: the 3TNM68 shares the bore × stroke (68 × 72 mm) with the older 3TNA68 / 3TN68 / 3TNE68 / 3TNV68 engines, but uses a different head gasket OEM (119125-01330 instead of 119651-01340) due to the Stage V version. Do you have an older TNV/TNE/TNA engine? Then order our gasket set SKU-80080 instead of this one.
