## Description

##### Liebherr D834 A7 engine after overhaul – ready-to-install unit

We offer a fully refurbished **Liebherr D834 A7** engine after a complete **overhaul**, prepared as a complete power unit for immediate installation or adaptation to a specific machine. This offer is intended for users who know exactly which engine they need and expect repeatable performance parameters while keeping downtime to a minimum.

###### Scope of overhaul work

- **Comprehensive engine block overhaul** – replacement of pistons, liners, rings, bearings, seals and auxiliary components with new or factory-refurbished **parts**.
- **Fuel injection system** – injectors and fuel pump inspected, overhauled or replaced and calibrated to Liebherr D834 A7 engine specifications.
- **Cylinder heads** – reconditioning of seats, replacement of valves and guides, leak testing and matching to the new **parts**.
- **Crankshaft** – measurement, grinding, balancing and assembly with new bearings, with verification of operating clearances.
- **Engine auxiliary equipment** – tested turbocharger, pumps, cooling system and filtration based on available high-quality replacement **parts**.

###### Dynamometer testing

Every overhauled Liebherr D834 A7 engine is started and loaded on an engine **dynamometer**. Dynamometer tests make it possible to confirm power output, torque and the stability of temperatures and pressures. On the customer’s request we provide a **dynamometer** test report documenting the course of the test.

###### Applications in machines

The **Liebherr D834 A7** engine can be used as:

- **engine for an excavator**, crawler or wheeled,
- **engine for a dump truck**,
- **engine for a Liebherr wheel loader**,
- **engine for an industrial or specialist machine**.

It is possible to adapt the engine to a specific model – adjusting the timing case, additional hydraulic pumps, brackets and auxiliary equipment so that installation in the machine is possible without any modification of its structure.

###### Why choose a ready overhauled engine?

- **Time savings** – the overhauled engine is **available** as a complete unit, with no need to wait for your old engine to be repaired.
- **Cost control** – fixed, known price of the unit with no unexpected surcharges for additional **parts**.
- **Risk reduction** – performance parameters confirmed on a **dynamometer**; the overhauled engine is prepared for operation under full load.
- **Configuration flexibility** – possibility to transfer selected auxiliary equipment from the old engine, where technically justified.

###### Liebherr service, repair and diagnostics

In addition to supplying the complete engine unit, we offer **service** for Liebherr engines: on-site engine repairs at the customer’s location or in our workshop, complete **overhaul**, ongoing **repairs** and computer and measurement **diagnostics**. We provide **construction machinery service** with call-out – our **mobile service** enables fault verification, first start-up of the engine after installation and selection of suitable consumable **parts**.

###### Liebherr engines – brand characteristics

**Liebherr** is a manufacturer of construction machinery and combustion engines, present in many market segments – from excavators and loaders, through cranes, to industrial and specialist machines. Liebherr engines are designed for operation in harsh conditions, with an emphasis on durability, stable performance parameters and straightforward **service** procedures.
