Part Number Check: Confirm 5I7523 or 5I-7523 from the old record, supplier record or removed sample.

Engine Check: Confirm whether the engine is Mitsubishi S6KT, S6K or a related 3066 application.

Old Sample Check: Provide clear photos of the removed cylinder block sleeve from multiple angles.

Repair Check: Check the piston, piston rings and cylinder block condition together before rebuilding the engine.

Cylinder Block Sleeve Replacement Notes

When replacing the 5I7523 cylinder block sleeve, the piston, piston rings, cylinder block condition and engine overhaul requirements should be checked together. If the sleeve type or repair condition is unclear, the old sleeve sample and measurements should be confirmed before shipment.

For Mitsubishi S6KT / S6K engine repair, the sleeve should be selected together with the piston and ring condition. If the old sleeve has abnormal wear, scoring, overheating marks or poor sealing traces, the related piston and ring set should also be inspected before rebuilding the engine.
