Crankshaft kit Yanmar 3TNV76 | 3D76E – John Deere X740 | Komatsu PC26MR | Landini 4630 | Wacker Neuson

Description

With this crankshaft kit, you can completely replace the crankshaft of the Yanmar 3TNV76 three-cylinder diesel engine in one go. Once the crankshaft comes out, the bearings, oil seals, and crankcase are all exposed — and anything you don't replace at that time means disassembling it all over again later. Therefore, in addition to the crankshaft, this kit also includes all four main bearings, the connecting rod bearings, new connecting rod bolts, the thrust washers, and the complete gasket set with both crankshaft oil seals.

✔️ Complete bearing kit — four main bearings, three connecting rod bearings, and thrust washers in standard size
✔️ Six new connecting rod bolts — these stretch during use and must not be reused
✔️ Includes complete gasket set with both crankshaft oil seals, oil pan and timing cover gasket
✔️ Exact OEM fit for all 3TNV76 and 3D76E variants

Kit contents

• 1× crankshaft Yanmar 3TNV76 — standard size (STD)
• 4× main bearing / bearing shell — STD
• 3× connecting rod bearing / bearing shell — STD
• 6× connecting rod bolt — 2 per connecting rod
• 1× thrust bearing kit (thrust washers)
• 1× complete gasket set — incl. head gasket, oil pan gasket, timing cover gasket, and front + rear crankshaft oil seal

Technical specifications

• Engine: Yanmar 3TNV76 (also Komatsu 3D76E)
• Cylinders: 3
• Bearing size: standard (STD) — the crankshaft is at standard size, so the supplied bearings are STD

Tip: the cause of crankshaft damage is almost always a lack of oil or contaminated oil. Check the oil pump and oil channels before installing the new shaft — a new crankshaft on a worn-out oil pump will not last long. During an overhaul, also replace the cylinder head bolts; just like the connecting rod bolts, they stretch and should not be reused.
