## Description

##### Cummins QSL8.9 engine after overhaul — complete drop-in unit

Available **Cummins QSL8.9** engine after a full workshop ****Overhaul****, prepared for immediate installation or reconfiguration for a specific machine. A solution for companies that need reliability, minimal downtime, and complete documentation from **dynamometer** tests.

###### Scope of work and verification

- Block and crank-piston assembly measured and inspected: new liners, pistons, rings, pins, bearings; clearances and alignment checked.
- Cylinder head machined: resurfacing, leak/pressure test, new guides, valves, and stem seals.
- Lubrication and cooling systems: new oil pump, serviced water pump, thermostat, oil cooler cleaned and pressure-tested.
- Fuel system fully verified: pump/injectors refurbished or replaced, flow and return tests; clean fuel system.
- Boost and intake: turbocharger inspected or rebuilt, leak-free intercooler, new sealing hardware.
- Final loaded test on the **dyno**: pressures, temperatures, smoke, and operating parameters confirmed with a test report.

###### Configurations and conversions

We match the accessory configuration (timing gear housing, flywheel/clutch housing, alternator, air compressor, wiring harness, ECU, manifolds) to your machine. We can install ancillaries from the old engine and adapt the harness — we minimize modifications so the installation is plug-and-play.

###### Applications

- Engine for excavators, wheel loaders, dumpers, rollers, screeners, crushers, and generator sets.
- Common cooperation with machines from JCB, Doosan, Terex, Volvo, Case, and New Holland.

###### What you get

- Available off the shelf — fast replacement keeps downtime to a minimum.
- Fully overhauled — operating parameters and compression within spec.
- Flexibility — conversion for a specific application and ECU maps according to the machine’s requirements.
- Warranty and **dyno** report — full documentation from commissioning and tests.

###### Service and support

**Stationary** and **mobile service**: **Diagnostics** (computer and mechanical), **Repair**, **Overhaul**, selection of **Parts** (OEM and aftermarket). We serve including **Kraków**, **Lesser Poland (Małopolska)** and **Podhale**; shipping and installation available across Poland, the EU, and worldwide.

Our headquarters is in Kojszówka, Lesser Poland Voivodeship.

###### FAQ

- Does the engine deliver full power? — Yes. Every overhauled unit undergoes a loaded dyno test and calibration of idle and system pressures.
- Will you match the ancillaries? — Yes. We transfer or supply compatible ancillaries and prepare the installation for the specific frame/driveline.
- What about warranty? — Workshop warranty with the option to extend after completing scheduled ****Service**** inspections.
