6222-31-1110 Crankshaft for S6D108 Engine

6222-31-1110 Fitment Checklist

Original part number: Compare the old crankshaft marking, parts book reference or supplier label with 6222-31-1110.

Engine model: Confirm the engine reference is S6D108 before ordering.

Journal size: Measure the main journal and rod journal diameter before ordering.

Gear end: Check the gear mounting side, keyway and timing gear structure.

Flywheel end: Check the bolt pattern and flywheel-side structure.

When Should the Crankshaft Be Replaced?

Journal scoring: Deep scratches or heat marks on the main journal or rod journal may indicate that the crankshaft is no longer suitable for reuse.

Bearing failure: Damaged main bearings or connecting rod bearings can quickly affect crankshaft surface condition and engine stability.

Low oil pressure: Poor lubrication can damage the crankshaft, bearings, oil pump and other rotating engine parts.

Abnormal engine noise: Heavy knocking, metallic noise or vibration should be checked before the engine returns to work.

Engine overhaul: During an S6D108 engine rebuild, the crankshaft should be measured and inspected together with the bearing set and lubrication system.

Replacement and Inspection Notes

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

Use the correct service manual for torque values, bearing clearance and assembly sequence.

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

Inspect the oil pump, oil pickup tube and oil filter if the previous failure was related to low oil pressure or oil contamination.

After installation, confirm oil pressure, engine noise and initial running condition before returning the machine to heavy-duty operation.

Ordering Information

For faster 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 6222-31-1110 matches your S6D108 engine application.

FAQ

What is 6222-31-1110 used for?

6222-31-1110 is listed on this page as a crankshaft reference for S6D108 engine applications. Final fitment should be verified by original part number, engine model and dimensional comparison.

How do I confirm if 6222-31-1110 fits my S6D108 engine?

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

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, oil contamination or low oil pressure 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.
