ME011604 Cylinder Liner for Mitsubishi 4D31 4D31T Engine

ME011604 Cylinder Liner for Mitsubishi 4D31 4D31T Engine Repair

The ME011604 cylinder liner is used for Mitsubishi 4D31 4D31T diesel engine repair and sleeve replacement work. It is commonly requested by workshops rebuilding light truck engines, Fuso Canter-type applications, compact machinery engines and used equipment power units.

This page is focused on the ME011604 liner only. Old directory-style liner tables with Komatsu, Cummins, Caterpillar and unrelated Mitsubishi part numbers should be removed from this product page to keep the search intent clear.

Identification Data for ME011604 Cylinder Liner

Application Scene: Light Truck and Compact Diesel Engine Rebuild

The ME011604 liner is more suitable for a Mitsubishi 4D31-family engine page than an excavator-only page. Many buyers search this part from light truck repair, small diesel engine rebuild, compact machinery maintenance or Fuso Canter-type engine service.

For these engines, the old sleeve sample is usually more useful than the equipment name. A used truck, imported machine or rebuilt engine may have incomplete records, replacement blocks or previous machining history.

The recommended confirmation method is to compare the removed liner, engine model, bore, outer diameter, total length and finish type before shipment.

Why Finish Type Should Be Checked Before Ordering

Some liner references mark the ME011604 group as semi-finished. If the sleeve is semi-finished, the workshop may need final boring or honing after installation to achieve the correct bore size, roundness, surface finish and piston clearance.

If the buyer expects a finished liner but receives a semi-finished sleeve, the rebuild can be delayed. If a semi-finished liner is installed without proper machining, the engine may develop low compression, oil consumption, piston scuffing or early ring wear.

Before ordering, confirm whether the repair job needs a finished sleeve, semi-finished sleeve, single liner, four-piece set, or related piston and ring components.

Common Repair Situations for 4D31 4D31T Engines

Why the Old Product Directory Should Be Removed

The old Product Description lists many liner numbers for Komatsu, Cummins, Caterpillar and Mitsubishi engines. That kind of table belongs in a category guide, not inside a single ME011604 product page.

Keeping unrelated numbers such as 3904167, 3904166, 3919937, 3022157, 5I-7523, 2W6000, 211-7826 or ME041105 can make the page look like a general cylinder liner directory instead of a focused Mitsubishi 4D31 4D31T liner page.

For better SEO clarity, this page should focus on ME011604, Mitsubishi 4D31 4D31T, 100 mm bore reference, finish type, old sleeve measurement and repair verification.

Pre-Order Verification Checklist

Before ordering ME011604, confirm the engine model, old sleeve number, bore size, outer diameter, total length and finish type. If the old liner is available, measuring the removed sleeve is the safest method.

Send photos of the old sleeve body, top edge, lower edge, part number marks and measurement points. If the engine block has been machined before, provide the block bore measurement and rebuild history as well.

Topvelsun can help compare the supplied photos and measurements before shipment to reduce wrong-part risk for remote buyers, repair workshops and parts distributors.

Installation and Workshop Notes

Clean the cylinder block bore before sleeve installation. Rust, carbon, burrs, old machining marks or block distortion can affect liner seating and final bore accuracy.

If the sleeve is semi-finished, final boring and honing should follow the engine rebuild specification. Check bore size, taper, roundness, surface finish and piston-to-liner clearance before final assembly.

During rebuild, inspect pistons, piston rings, injectors, air intake filtration, lubrication condition and cooling performance together. A sleeve repair may fail early if the original cause was overheating, dust ingestion, poor lubrication or incorrect machining.

After assembly, monitor oil consumption, exhaust smoke, crankcase pressure, starting condition and operating temperature during the first operating period.

FAQ

What engine is ME011604 mainly used for?

ME011604 is mainly associated with Mitsubishi 4D31 and 4D31T cylinder liner applications. Final fitment should be verified by old sleeve dimensions and engine information.

Can this page mention ME011606 or ME011523?

Yes, they can be mentioned as related checking references in the same 4D31-family liner data. However, the main product focus of this page should remain ME011604.

Is this liner only for excavators?

No. ME011604 is better described as a Mitsubishi 4D31 4D31T engine liner. It may be used in light truck, compact machinery or small diesel engine repair depending on the actual engine configuration.

Does ME011604 require machining?

Some references list this liner group as semi-finished. Buyers should confirm whether they need a finished or semi-finished sleeve, and the workshop should complete machining if required.

Can Topvelsun help verify the correct sleeve before shipment?

Yes. Buyers can send old sleeve photos, engine information, block bore measurements and dimension photos. Topvelsun can help compare the information before order confirmation.
