For Caterpillar 3304 3306 Engine Cylinder Liner 371-5941 1105800 2P-8889

371-5941 1105800 2P-8889 Cylinder Liner for Caterpillar 3304 3306 Engine Repair

The 371-5941 1105800 2P-8889 cylinder liner is used for Caterpillar 3304 3306 engine repair and rebuild work. This liner group is commonly ordered for older Caterpillar 3300 Series engines used in loaders, dozers, scrapers, compactors, industrial engines and earthmoving equipment.

This page is focused on the 371-5941 1105800 2P-8889 liner group only. Before ordering, the old liner, engine arrangement, seal kit requirement and physical dimensions should be checked together, especially when the engine has previous rebuild history.

Identification Data for Caterpillar 3304 3306 Cylinder Liner

Application Scene: Older Earthmoving Equipment Engine Rebuild

This liner is usually not purchased for a new-generation electronic engine. It is more often needed when a repair shop is rebuilding an older mechanical Caterpillar 3304 or 3306 engine after long service hours, overheating, coolant neglect, dust ingestion or piston ring failure.

Typical machines using 3304 3306 engine references may include wheel loaders, track-type tractors, scrapers, compactors, articulated trucks and industrial power units. The correct liner should be selected by engine arrangement and old liner measurements, not by machine category alone.

For used equipment fleets, the engine may have been rebuilt or replaced during previous service. A machine model can help narrow the search, but the removed liner and engine nameplate are more reliable for final confirmation.

Why the Seal Kit Should Be Checked Together

For wet cylinder liner engines, the liner itself is only one part of the sealing system. If coolant leakage, coolant in oil or liner wall corrosion is found, the sealing rings and block sealing area should be inspected together.

Some buyers search by 371-5941, while others search by 1105800 or 2P-8889. These numbers may point to the same liner reference group, but the actual supply type can still vary by supplier. Confirm whether seals are included before ordering.

If the old engine has repeated coolant leakage after rebuild, do not replace the liner alone without checking liner protrusion, counterbore condition, seal grooves, coolant quality and block corrosion.

Common Repair Conditions

Pre-Order Verification Checklist

Before ordering 371-5941 1105800 2P-8889, confirm the engine model, engine arrangement, old liner part number and removed liner dimensions. Key checks include bore reference, total length, flange area, sealing area diameter and seal groove position.

If the liner is for a used Caterpillar machine, provide both the machine model and the engine information. For imported used equipment, the engine installed in the machine may not match the original factory configuration.

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

Installation and Rebuild Notes

Clean the cylinder block bore, counterbore and sealing area before installation. Rust, scale, burrs, carbon deposits or old seal residue can affect liner seating and sealing performance.

Check liner protrusion according to the service manual. Uneven liner height may lead to combustion leakage, head gasket failure, coolant leakage or repeated engine repair.

Use the correct liner seals and assembly lubricant. Do not force the liner into a dirty or damaged bore. If installation resistance is abnormal, stop and inspect the liner size, seal position and block condition.

After rebuild, monitor coolant level, oil condition, exhaust smoke, blow-by and engine temperature. For older earthmoving equipment, early checks after repair are important because secondary causes such as poor cooling, dirty intake air or injector problems can damage the new liner again.

FAQ

Are 371-5941 1105800 and 2P-8889 used for the same liner group?

Yes. These numbers are commonly listed together for Caterpillar 3304 3306 cylinder liner applications. Final fitment should still be verified by engine arrangement, old liner and dimensions.

What engines can this cylinder liner be used for?

This liner is commonly associated with Caterpillar 3304 and 3306 engine references. The exact match should be confirmed by engine data and removed liner measurements.

Is this product only for excavators?

No. Caterpillar 3304 and 3306 engines are used in many types of earthmoving and industrial equipment, including loaders, dozers, scrapers, compactors and industrial power units. Engine information is more reliable than machine category alone.

What should be checked before ordering?

Check the old liner number, bore reference, total length, flange area, sealing groove position and whether a liner seal kit is required. Measuring the removed liner is the safest method.

Can Topvelsun help verify the correct liner before shipment?

Yes. Buyers can send the old liner photos, engine nameplate, machine model and measurement photos. Topvelsun can help compare the information before order confirmation.
