Mitsubishi 6D22T Engine Cylinder Liner Sleeve ME051500

ME051500 Cylinder Liner for Mitsubishi 6D22T Engine

The ME051500 cylinder liner is used for Mitsubishi 6D22 and 6D22T diesel engine overhaul service. It is also commonly searched as a cylinder sleeve, engine liner or wet cylinder liner for Mitsubishi heavy duty engine applications.

This page focuses on the ME051500 cylinder liner signal. Related references such as ME051217, ME051501, ME051502 and ME051503 are included as cross reference support, but final fitment should still be verified by the old liner number, engine model, bore size, outer diameter, liner height and cylinder block condition before ordering.

Technical Dimensions and Identification Notes

Cross Reference and Number Format

The main part number for this page is ME051500. Some catalogs also list ME051217, ME051501, ME051502 and ME051503 in the same Mitsubishi cylinder liner reference group.

Additional reference numbers such as 51-05669-000 and 5669000 may appear in catalog data for related Mitsubishi 6D22 and 6D24 cylinder liner applications. These numbers should be used for identification support, not as automatic interchange confirmation.

Cylinder liners with similar Mitsubishi numbers may still vary by machining status, flange height, outer diameter, liner protrusion requirement or engine block specification. Before quotation, compare the removed liner and confirm the engine build information.

Mitsubishi 6D22 6D22T Engine Application Notes

The ME051500 cylinder liner is mainly prepared for Mitsubishi 6D22 and 6D22T diesel engine overhaul work. It is used when the cylinder bore is worn, scratched, pitted, cracked or out of service limit after long engine operation.

Mitsubishi 6D24 and 6D24T references may appear in cross reference catalogs, but they should be treated as engine reference information only unless the old liner dimensions and engine block configuration are confirmed. For repair accuracy, use the old liner number and measured dimensions together.

Common Failure Symptoms

Low compression after long engine running hours.

Blue smoke or increased oil consumption caused by poor piston ring sealing.

Coolant leakage into the cylinder or crankcase when liner sealing is damaged.

Vertical scoring, pitting or corrosion marks on the cylinder liner surface.

Abnormal knocking, overheating or poor combustion after cylinder wear becomes severe.

Repeated gasket failure caused by incorrect liner protrusion or uneven cylinder block seating.

Troubleshooting Before Replacement

Before replacing the ME051500 cylinder liner, inspect the complete cylinder block, piston, piston ring, cooling system and lubrication system. Liner damage is often related to overheating, poor coolant maintenance, dirt entry, incorrect assembly clearance or worn piston components.

Measure the old liner bore and compare it with the replacement liner specification.

Check cylinder block counterbore condition and liner seating surface.

Inspect piston, piston rings and piston pin condition before reassembly.

Check coolant passages for rust, scale or cavitation damage.

Inspect for overheating history, lubrication failure or air filter leakage.

Confirm the correct liner protrusion after installation according to engine service requirements.

Installation and Maintenance Notes

Clean the cylinder block bore and liner seating area before installation.

Do not install a new liner into a damaged or corroded block seat without inspection.

Use the correct seals, O-rings or packing parts if the engine design requires them.

Check liner protrusion after installation and keep all cylinders within service tolerance.

Install matching piston rings and confirm ring end gap before final assembly.

Use clean engine oil during assembly to reduce dry-start wear.

After overhaul, check coolant level, oil condition, exhaust smoke and compression performance during initial running.

FAQ

What is ME051500?

ME051500 is a Mitsubishi cylinder liner reference commonly used for 6D22 and 6D22T diesel engine overhaul applications.

Is ME051500 the same as ME051217?

ME051217 appears in the same cylinder liner reference group in some catalogs. It should be treated as a cross reference and confirmed by the old liner dimensions before ordering.

Can this liner be used for Mitsubishi 6D24 engine references?

Some catalogs connect ME051500 with Mitsubishi 6D24 and 6D24T references. The final decision should be based on the removed liner number, engine build and measured dimensions.

What dimensions should be checked before ordering?

Check bore diameter, outer diameter, overall length, collar diameter, collar thickness and liner protrusion requirement before ordering.

Should cylinder liners be replaced as one piece or as a full engine set?

For engine overhaul, cylinder liners are often replaced as a complete engine set to keep wear and sealing conditions consistent. Single-piece replacement should be confirmed by repair condition and stock policy.

What causes early cylinder liner failure after replacement?

Early failure can be caused by poor block cleaning, incorrect liner protrusion, overheating, coolant cavitation, wrong piston ring clearance, dirt entry, lubrication failure or incorrect assembly procedure.
