ME011626 Cylinder Liner Sleeve for Mitsubishi 6D31 6D31T Engine

ME011626 Cylinder Liner for Mitsubishi 6D31 Engine

The ME011626 cylinder liner is used for Mitsubishi 6D31 and 6D31T diesel engine overhaul service. It is commonly searched as a cylinder sleeve, engine liner or cylinder liner replacement for heavy equipment engine repair.

This page focuses on the ME011626 cylinder liner signal. Compatible model references may include Kobelco SK200-1, SK200-3, Kato HD700-5 and HD700-7, but final fitment should be verified by the old liner number, engine model, bore size, outer diameter, overall length and cylinder block condition before ordering.

Technical Dimensions and Identification Notes

Cross Reference and Number Format

The main part number for this page is ME011626. Related Mitsubishi 6D31 cylinder liner references may include ME011523 and ME011605 in supplier listings.

ME011604 also appears in some broad 4D31 and 6D31 cylinder liner reference groups. However, because this website already has a separate ME011604 cylinder liner page, this page should keep ME011626 as the main part number and avoid using ME011604 as a second main signal.

Cylinder liners with related Mitsubishi numbers may still vary by finished status, outer diameter, liner height, flange shape, machining allowance or engine block requirement. Cross reference numbers should be used for identification support, not as automatic interchange confirmation.

Mitsubishi 6D31 6D31T Engine Application Notes

The ME011626 cylinder liner is mainly prepared for Mitsubishi 6D31 and 6D31T 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 6D31 engines may be used in excavators and other heavy equipment. Machine model is helpful for initial checking, but the removed liner and engine information are more reliable for final confirmation.

Kobelco SK200 and Kato HD700 Model References

This cylinder liner is often searched for excavator repair references such as Kobelco SK200-1, SK200-3, Kato HD700-5 and HD700-7. These model names are useful for buyer search and initial identification when the old liner number is not available at the first inquiry stage.

These model references should not replace engine and liner verification. Before ordering, compare the old liner dimensions, machine serial number, engine model and cylinder block condition to reduce wrong-part risk.

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 ME011626 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, dust 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 ME011626?

ME011626 is a Mitsubishi cylinder liner reference commonly used for 6D31 and 6D31T diesel engine overhaul applications.

Is ME011626 used for Mitsubishi 6D31 engine?

Yes. ME011626 is commonly listed with Mitsubishi 6D31 cylinder liner references. Final fitment should be verified by old liner number, engine model and measured dimensions.

Why not use ME011604 as the main number for this page?

ME011604 already has a separate product page on this website. To avoid duplicate part number competition, this page should focus on ME011626 and treat ME011604 only as a broad catalog checking reference.

Which excavator models are common references?

Common references include Kobelco SK200-1, SK200-3, Kato HD700-5 and HD700-7. These should be treated as model references, not guaranteed applications.

What dimensions should be checked before ordering?

Check bore diameter, outer diameter, overall length, liner finish type, flange shape and liner protrusion requirement before ordering.

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

For a six-cylinder engine overhaul, cylinder liners are often replaced as a complete 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.
