2W-6000 2W6000 Cylinder Liner for Caterpillar 3406 3408 3412 Engine

2W-6000 2W6000 Cylinder Liner for Caterpillar 3406 3408 3412 Engine Rebuilds

The 2W-6000 2W6000 cylinder liner is used for Caterpillar 3406 3408 3412 and related 3400 Series engine rebuild applications. It is commonly requested when a heavy-duty engine shows bore wear, coolant-side corrosion, low compression, piston scuffing, coolant contamination or repeated sealing failure.

This page is focused on the 2W-6000 liner group only. The old page title uses E137 Excavator, but the stronger technical direction is Caterpillar 3400 Series engine service. Final fitment should be verified by engine arrangement, old liner dimensions and seal requirements before ordering.

Identification Data for 2W-6000 2W6000 Cylinder Liner

Application Scene: Heavy-Duty Caterpillar 3400 Series Fleet Maintenance

The 2W-6000 liner is more suitable for a heavy-duty Caterpillar 3400 Series engine page than an excavator-only page. These engines may appear in trucks, generator sets, wheel loaders, dozers, marine engines, industrial engines, quarry trucks, scrapers and other large equipment applications.

For truck and equipment fleets, this liner is usually ordered during scheduled overhaul, coolant leakage repair, compression loss diagnosis or high-hour rebuild. For generator and industrial engines, the buyer should check whether the engine has long standby periods, coolant neglect, corrosion, or previous rebuild history.

Because the same liner reference can appear across multiple machine categories, the safest confirmation method is engine information plus removed liner measurements, not the equipment model alone.

Why This Page Should Not Keep the Old Cylinder Liner Directory

The old Product Description lists many liner numbers for Komatsu, Cummins, Caterpillar and Mitsubishi engines. Those numbers may be useful in a category guide, but they should not remain inside a single 2W-6000 product page.

Keeping unrelated numbers such as 3904167, 3904166, 3919937, 3022157, 5I-7523 or ME013366 can make this page look like a general cylinder liner catalog instead of a focused page for Caterpillar 3400 Series wet liners.

For better SEO clarity, this page should focus on 2W-6000 2W6000, Caterpillar 3406 3408 3412, wet liner dimensions, seal requirements and engine rebuild checks.

Common Repair Situations for 3406 3408 3412 Engines

Seal Package and Supply Type Check

Before purchasing 2W-6000 2W6000, confirm whether the order requires a bare liner, liner with seals, or a complete cylinder kit. Some buyers search by the liner number, while the workshop may expect sealing rings or related rebuild parts to be included.

A correct liner number with the wrong supply type can still delay the overhaul. This is common in remote purchasing when the buyer, mechanic and supplier use different descriptions for the same repair job.

If the old liner is available, send photos of the liner body, flange area, lower sealing area and measurement points before shipment. Topvelsun can help compare the supplied information before order confirmation.

Pre-Order Verification Checklist

Before ordering 2W-6000 2W6000, confirm the engine model, engine arrangement, old liner number and physical dimensions. Key checks include bore, outer diameter, total length, flange area, sealing area diameter and seal groove position.

If the liner is for a truck engine, generator set, marine engine or heavy equipment engine, provide the engine nameplate and machine information together. Engine data is more reliable than machine category alone.

If the engine has been rebuilt before, provide the rebuild history or removed liner measurements. Mixed aftermarket parts or previous machining can change the final confirmation process.

Installation and Maintenance Notes

Clean the cylinder block liner bore, counterbore and sealing area before installation. Rust, scale, old seal residue, burrs or coolant-side pitting can damage the sealing rings and cause coolant leakage after assembly.

Check liner protrusion according to the engine service manual. Uneven liner height can affect fire ring loading, cylinder head gasket life and combustion sealing.

During overhaul, inspect pistons, piston rings, injectors, cooling system, lubrication quality, turbocharger air path and air filtration together. A liner replacement can fail early if the original cause was overheating, dust ingestion, poor lubrication or injector-related piston damage.

After rebuild, monitor coolant level, oil condition, crankcase pressure, exhaust smoke and operating temperature during the first operating period.
