4009220 4024767 Cylinder Liner for Cummins K19 QSK19 Engine

4009220 4024767 Cylinder Liner for Cummins K19 QSK19 Heavy-Duty Rebuilds

The 4009220 4024767 cylinder liner is used for Cummins K19 QSK19 KTA19 engine overhaul and heavy-duty service repair. This liner group is commonly selected when a high-displacement Cummins engine shows liner wear, coolant-side cavitation, low compression, piston scuffing, coolant contamination or repeated sealing failure.

This page is focused on the K19-family liner reference group only. The old cylinder liner, liner kit type, engine serial number, CPL and physical dimensions should be checked before ordering because K-series engines may be used in different power ratings, machine types and rebuild histories.

Large Engine Liner Identification

For K19 engine repairs, the buyer should first confirm whether the order requires a bare cylinder liner, a liner with seals, or a full liner kit. In many aftermarket references, 4009220 appears as the cylinder liner reference, while 4024767 is commonly used in the same K19 liner service group.

Where This K19 Liner Is Usually Needed

K19-family engines are often found in applications where downtime is expensive: mining machines, generator sets, marine auxiliary engines, oilfield equipment, pump drive engines and heavy construction machinery. In these environments, the liner is not only a wear part; it is part of the engine's combustion sealing and cooling boundary.

A worn wet liner can cause compression loss, combustion gas leakage, coolant migration, coolant-side pitting, piston ring wear and repeated head gasket problems. If the engine has operated under continuous load, all liners should be measured during teardown instead of replacing only the visibly damaged cylinder.

For standby generator engines, liners may also suffer from coolant neglect, corrosion, long idle periods and delayed maintenance. For mining and oilfield engines, dust ingestion, overheating and heavy load cycles can accelerate bore and piston ring wear.

Bare Liner, Liner With Seals, or Liner Kit

Before purchasing 4009220 4024767, confirm what the workshop actually needs. Some repair jobs require only the liner. Others require seals, O-rings or a complete service kit. Ordering the wrong supply type can delay the rebuild even when the liner size is correct.

Inspection Points During K19 Engine Teardown

During disassembly, inspect the liner bore surface, upper wear ridge, lower sealing area, outer coolant wall, flange seating surface and block counterbore. Wet liner engines are sensitive to coolant condition, liner protrusion and sealing ring installation.

If there is cavitation on the coolant side, the cooling system should be checked together with the liner replacement. Coolant chemistry, poor grounding, trapped air, corrosion, incorrect coolant additives or long service intervals can contribute to repeated wet liner failure.

If there is piston scuffing or deep scoring, also inspect piston cooling, injector condition, lubrication quality, air filtration and turbocharger condition. A new liner may fail early if the root cause is not corrected.

Pre-Order Confirmation for 4009220 4024767

Before ordering, confirm the complete engine model, engine serial number, CPL, removed liner number and actual measurements. Key dimensions include bore, total length, flange outer diameter, flange width, sealing area diameter and O-ring groove position.

If the liner is for a generator set or marine engine, the engine nameplate is usually more useful than the equipment name. If the liner is for a mining machine or heavy construction machine, provide both the machine model and engine information.

Topvelsun can help compare the old liner photos, engine information and measurement photos before order confirmation to reduce wrong-part risk.

Installation Notes for K19 Wet Cylinder Liners

Clean the cylinder block liner bore, counterbore and sealing area before installation. Any rust, burr, scale, carbon deposit or pitting can affect liner seating and O-ring sealing.

Check liner protrusion according to the service manual. On heavy-duty wet sleeve engines, uneven protrusion can affect fire ring loading, cylinder head gasket sealing and combustion pressure retention.

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

After rebuild, monitor coolant level, oil condition, exhaust smoke, crankcase pressure and operating temperature. Early checks are important for engines working under continuous load or remote-site operation.

FAQ

Are 4009220 and 4024767 used for the same K19 liner group?

Yes. These two numbers are commonly listed together in K19 cylinder liner and liner kit references. The final supply type should still be checked because some listings may refer to a bare liner, while others may refer to a liner with seals or a kit.

What engines can this liner be used for?

This liner is commonly associated with Cummins K19, QSK19 and KTA19 engine references. Final fitment should be confirmed by engine serial number, CPL and removed liner dimensions.

Is this product only for excavators?

No. K19-family engines are used in mining equipment, generator sets, marine engines, oilfield engines, industrial engines and heavy construction machinery. Engine information is more reliable than machine category alone.

What should be measured before ordering?

Measure the bore, total length, flange outer diameter, flange width, sealing area diameter and O-ring groove position. Comparing the removed liner is the safest method before shipment.

Can Topvelsun help check the correct liner before shipment?

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