The crankshaft is the absolute heart of the engine, converting the linear motion of the pistons into rotational motion. For the Yanmar 4TNV94 engine, which powers various compact construction equipment, a reliable, high-quality crankshaft is non-negotiable. Our replacement Crankshaft P/N 129900-35500 (12990035500) is manufactured to meet or exceed OEM specifications, ensuring perfect balance, optimal strength, and a long service life. This is the definitive answer to engine issues caused by a compromised crankshaft, often indicated by abnormal vibration or excessive engine noise.
We focus on providing the most durable engine bearing sets, connecting rod bearings, and thrust washers to support the rotation of this critical component. Choosing our high-quality aftermarket engine components helps fleet managers and repair shops globally in maintaining top performance, minimizing downtime, and effectively solving high oil consumption in Yanmar 4TNV94 engines caused by poor component alignment.
From complete engine assemblies to the smallest seals, we cover every component.

LIKE US ON FACEBOOKUnderstand the critical spare parts that keep your heavy machinery running smoothly.
Liner Kit (Cylinder Liner): The replaceable sleeve inside the engine block that the piston moves within. Komatsu PC200-8 6D107 Liner Kit.
Piston Ring: Rings fitted into grooves on the piston. They seal the combustion chamber and regulate oil consumption. Caterpillar 320D C6.4 Piston Ring.
Gasket Head (Cylinder Head Gasket): A critical seal between the engine block and the cylinder head, containing combustion pressure and coolant. Isuzu 4HK1 Gasket Head.
Nozzle (Fuel Injector): Delivers finely atomized fuel into the combustion chamber. Installed in the cylinder head. Cummins QSB6.7 Injector Nozzle.
Engine Bearing (Main Bearing): Supports the crankshaft within the engine block. Essential for smooth rotation. Yanmar 4TNV98 Engine Bearing Set.
Valve Guide: A bushing in the cylinder head that supports and guides the movement of the engine valve stem. Kubota V3307 Valve Guide.
Flameout Solenoid: An electrical device that cuts off the fuel supply to stop the diesel engine. Located near the fuel pump. Weichai WP6 Flameout Solenoid.
Turbocharger: An air compressor driven by exhaust gases to force more air into the engine, increasing power. Mounted to the exhaust manifold. Komatsu 6D102 Turbocharger.
Water Pump: Circulates coolant through the engine block and radiator to regulate temperature. Mounted on the front of the engine block. Caterpillar 330D C9 Water Pump.
Pressure Switch (Oil Pressure Switch): Monitors engine oil pressure and alerts the operator to low pressure. Screwed into the engine block or oil filter housing. Isuzu 6BG1 Oil Pressure Switch.
Common Fault: Excessive Oil Consumption on Cummins B5.9-C Engine
Symptom: The Cummins B5.9-C engine is consuming oil at an alarming rate, leading to frequent top-ups and blue smoke from the exhaust.
Processing Solution: 1. Inspect the piston rings and cylinder liner for wear or damage. High oil consumption is often due to worn rings failing to seal the combustion chamber. 2. Check the turbocharger seals for oil leaks into the intake or exhaust. 3. Verify the valve stem seals are intact. If internal components like the piston rings are severely worn, a heavy equipment engine total overhaul with a high-quality engine overhaul kit is the most effective permanent solution.
Routine Oil & Filter Change: Always use the specified engine oil type and genuine filters to protect critical components like the Crankshaft and Engine Bearings.
Cooling System Check: Regularly inspect the radiator and coolant for leaks. Overheating drastically reduces the life of Gasket Head and other internal seals.
Fuel System Health: Use clean fuel and replace the fuel filter (essential for protecting Injector Nozzles) according to manufacturer schedules.
Belt Tension: Check and adjust the tension of the engine belt to ensure the Water Pump and alternator operate correctly.
