Construction machinery parts Crankshaft 3432010011 For Engine S6K S6KT

3432010011 Crankshaft for S6K / S6KT Engine

This 3432010011 crankshaft is supplied for S6K / S6KT engine repair and overhaul applications. The crankshaft is a core rotating component that works with pistons, connecting rods, main bearings, connecting rod bearings, thrust bearings, flywheel and timing components.

Crankshaft fitment should not be confirmed by engine name only. Before ordering, compare the original part number, journal size, gear-end structure, flywheel-end structure and engine configuration with the old crankshaft.Short answer: 3432010011 is a crankshaft reference for S6K / S6KT diesel engine applications. It should be confirmed by the original part number, engine model, main journal size, rod journal size, gear end, flywheel end and machine serial number before ordering.

What to Check Before Ordering

Original part number: Check the old crankshaft marking, parts book reference or supplier label against 3432010011.

Engine model: Confirm whether the engine reference is S6K or S6KT before ordering.

Main journal and rod journal size: Measure journal diameter and confirm whether the crankshaft is standard size or has been reground.

Gear end and flywheel end: Compare the gear mounting side, keyway, bolt pattern and flywheel-side structure.

Related parts: Main bearings, connecting rod bearings, thrust bearings and oil pump condition should be checked during crankshaft replacement.

Common Reasons for Crankshaft Replacement

Bearing damage: Main bearing or connecting rod bearing failure can scratch, overheat or deform crankshaft journals.

Low oil pressure: Poor lubrication may damage journals, bearings and other rotating engine components.

Abnormal engine noise: Knocking, heavy metallic noise or vibration may indicate bearing or crankshaft wear.

Overhaul inspection: The crankshaft should be inspected carefully when rebuilding an S6K / S6KT engine.

Visible cracking or scoring: Cracks, deep scratches, heat marks or journal damage require careful inspection before reuse.

Installation and Maintenance Notes

Clean the engine block, oil passages and bearing seats before installation.

Use the machine-specific service manual for torque values, bearing clearance and assembly sequence.

Check main bearings, connecting rod bearings and thrust bearings before final assembly.

Inspect the engine oil pump, oil pickup tube and oil filter if the old crankshaft failed because of lubrication problems.

After installation, confirm oil pressure and abnormal noise during initial start-up before returning the machine to heavy work.

Ordering Information

For a fast confirmation, please send the engine model, machine model, original part number, crankshaft photos, journal measurements, gear-end photo and flywheel-end photo. This helps confirm whether 3432010011 matches your S6K / S6KT engine application.

FAQ

What is 3432010011 used for?

3432010011 is listed on this page as a crankshaft reference for S6K / S6KT engine applications. Final fitment should be verified by the original part number and engine configuration.

Can this crankshaft be confirmed by engine model only?

No. Crankshafts should be confirmed by engine model, original part number, journal size, gear end, flywheel end and machine serial number.

Should bearings be checked when replacing a crankshaft?

Yes. Main bearings, connecting rod bearings and thrust bearings should be checked during crankshaft replacement. Bearing wear or oil contamination can damage a new crankshaft quickly.

What photos should I send for confirmation?

Please send photos of the old crankshaft, visible part marking, main journals, rod journals, gear end, flywheel end and engine model plate.

How do I confirm if 3432010011 fits my S6K or S6KT engine?

Confirm the engine model, original part number, main journal size, rod journal size, gear end, flywheel end and machine serial number. Photos of the old crankshaft and engine plate are recommended before ordering.

What parts should be checked when replacing a crankshaft?

Main bearings, connecting rod bearings, thrust bearings, piston and connecting rod condition, engine oil pump, oil passages and oil filter condition should be checked during crankshaft replacement.
