Assembling a Complete Cummins KTA19 Cylinder Kit — Understanding the Liner Seals

For customers rebuilding a Cummins KTA19, the cylinder kit can be purchased separately from Diesel Pro Power as a ready-to-assemble package. Each kit contains the cylinder liner, piston with rings, wrist pin, connecting rod, and the full liner seal set. While most rebuilders choose our complete overhaul kit for better value when replacing multiple cylinders, individual cylinder kits are available for partial rebuilds or single-cylinder repairs.

In a recent demonstration, Dion from Imperial Diesel Service showed how to assemble one of these cylinder kits as a complete unit. His focus was on the liner seals — small but critical components that keep coolant and combustion pressures where they belong.

Why the Seals Matter

The liner seals keep the cooling system and oil system separate and allow the KTA19 to maintain its high compression. Skipping steps or installing the wrong seal in the wrong groove can lead to:

• Coolant leaks into the crankcase

• Oil contamination and bearing damage

• Loss of compression and power

• Premature engine failure

Following the correct assembly process ensures your KTA19 runs reliably after repair or partial overhaul.

Buy Individual Cylinder Kits or a Full Overhaul Kit

At Diesel Pro Power, we understand that every engine repair project is different. Some customers only need to replace a single damaged cylinder, while others are preparing for a complete engine rebuild. That’s why we make it simple to get exactly what you need — whether it’s one Cummins KTA19 cylinder kit or a complete overhaul kit designed to restore your entire engine.

Individual KTA19 Cylinder Kits — Perfect for Targeted Repairs

If you’re dealing with a single cylinder failure, scoring, or localized wear, replacing just that cylinder can be the most practical and cost-efficient solution. Our individual KTA19 cylinder kits come fully equipped with the core components required for one complete cylinder assembly. Each kit includes:

• A precision-machined cylinder liner

• A fully assembled piston with rings for proper combustion sealing

• Wrist pin and retainers for secure piston-rod connection

• A complete liner seal kit with all O-rings and gaskets needed to keep coolant, oil, and compression where they belong

These kits are engineered for direct fitment into Cummins KTA19 engines, ensuring dependable performance without the guesswork of sourcing each part separately. Purchasing an individual kit is ideal if the rest of your engine is in good condition and only one cylinder requires service.

Complete KTA19 Overhaul Kits — Maximum Value for Full Rebuilds

For customers rebuilding several cylinders — or refreshing an entire engine — our complete KTA19 overhaul kits are the smarter choice. Instead of buying six separate cylinder kits and sourcing additional components, a full overhaul kit gives you everything you need in one package. Each kit typically contains:

• All six cylinder kits — liners, pistons, rings, pins, retainers, and liner seal sets

• Main and rod bearings for a fresh bottom end

• A comprehensive gasket set to reseal the engine during reassembly

• Other essential top-end and lower-end components required for a professional-quality rebuild

Choosing the overhaul kit saves money compared to buying individual parts piece by piece, and it guarantees component compatibility — a major advantage when working on a high-output engine like the KTA19. You’ll also reduce downtime by ordering everything at once rather than tracking multiple part numbers and shipments.
