Cummins QSK 2008 Technical Manual – ReCon Engine Handbook for Parts & Core Data

Ever had a customer bring in a QSK that’s been swapped with parts from three different engines, and you’re stuck trying to figure out what ECM calibration it actually needs? That’s where aftermarket data fails you. The factory Cummins QSK 2008 Technical Manual is the only document that spells out the ECM and Fuel Pump Calibration Policy, the core acceptance standards, and the exact part number cross-references. 54 pages, direct from Cummins ReCon. No guesswork.

ECM and Fuel Pump Calibration Policy – Why It Matters

Most techs skip checking ECM calibration compatibility when installing a ReCon engine. They throw the engine in, fire it up, and wonder why the fuel system acts up. This manual’s Introduction Tab clearly states the ECM and Fuel Pump Calibration Policy on page K/QSK-A-3. You get the official policy on when a recalibration is required and how to handle pump swaps. Without it, you’re flying blind. That policy alone can save you from a comeback. If you work on marine engines, check the Cummins Marine Engine Handbook for additional coverage.

Core Inspection Procedure and Acceptance Standards

Returning a core that gets rejected because you missed a crack or didn’t follow packaging specs costs you money. The Core Information Tab gives you the Core Inspection Procedure, Core Acceptance Standards, and even Core Packaging Illustrations. Page numbers? The core conversion charts for KT19, KTA19, KTTA19, and QSK19 are all there. You get the visual references for what a acceptable core looks like. No more arguing with the distributor over a borderline return. For a full parts catalog, the Cummins FD40 Technical Manual – OEM Parts Catalog 434 Pages covers part numbers in depth.

Part Number and Engine Model Details for the K19 and QSK19 Families

This isn’t a generic list. You get separate construction breakdowns: KT19, KTA19, KTTA19, KTA19 Gen-Set, KT19 Marine, KTA19 Marine, and QSK19. Each has its own part number listing. If you’re trying to order a ReCon engine and need to verify the engine model from the dataplate, this section eliminates the confusion. Cross-reference tables link shop orders to part numbers. For older military-spec engines, the Cummins NTA-855-L4 1986 Technical Manual – OEM Army Specs covers the NTA series.

Options Information – What You Might Be Missing

Six pages of options (K/QSK-D-3 to 7) list every configuration Cummins offered for these engines. That includes accessories, mounting variations, and special-order items. If you’re putting a ReCon engine into a non-standard application, you need to reference this section to confirm the options match your build. Missing an option can mean drilling holes in the wrong spot or ordering the wrong turbo. This manual focuses on the engine, not the Manual Transmission, so keep your drivetrain docs handy.

54 Pages – What’s Actually in This Manual

Cover to cover: Introduction Tab (ReCon engine considerations, selling points, calibration policy), Part Number/Engine Details Tab, Cross Reference Information Tab, Options Information Tab, Core Information Tab, Warranty Tab (including Extended Coverage Plans), and Literature Tab (none included). No fluff. No reprints of generic data. It’s a distributor handbook designed for parts identification and core management. If you’re pairing this engine with a manual transmission, refer to the OEM transmission documentation. Manual Transmission specs are separate.

Does This Manual Cover the Fuel System?

Yes, but only from a calibration and policy standpoint. The ECM and Fuel Pump Calibration Policy tells you the rules. If you need fuel system service procedures, that’s a different book. This manual exists to get the right engine, with the right calibration, and the correct core return – nothing more, nothing less.

Does this manual contain torque specifications for assembly?

No. This is a parts and core reference, not an engine overhaul manual.

Can I use this to rebuild my QSK engine?

Not for step-by-step assembly procedures. It covers ECM calibration policy, core inspection, and part numbers only.

How do I find the correct part number for my KTA19 ReCon engine?

Open the Part Number/Engine Details Tab. Locate the KTA19 Construction section (page K/QSK-B-3). Cross-reference your engine serial number with the shop order information in the Cross Reference Tab. If you have a shop order number, use the Shop Order To Part Number Cross Reference (page K/QSK-C-3). The manual lists all part numbers for KT19, KTA19, KTTA19, KTA19 Gen-Set, KT19 Marine, KTA19 Marine, and QSK19. Match your engine model and build configuration to the correct ReCon part number. Don’t skip the Options Information tab – that tells you if your engine had special-order parts that affect the part number.

Is the manual specific to the 2008 model year?

Yes, the revision date is March 2008 (REV: 03-08). It covers the QSK19 and K19 family engines as of that date. Later revisions may exist, but this is the official Cummins document for that period.

If you’re dealing with Cummins ReCon engines, having the factory data saves you from sending back the wrong core or ordering the wrong calibration. Access the Factory Manual and get the exact reference documentation Cummins intended.
