# Installation of Perkins Engine (CAT C4.4) in PowerScreen Screener

> Installing an engine in the PowerScreen Warrior 1800 screener in Slovakia was a challenge that required precise diagnostics and unconventional solutions. Discover how the operation unfolded, which components were replaced, and how long-lasting machine efficiency was ensured.

### Challenges and Solutions

Installing the engine in a machine that had been standing for several months and was left in a partially disassembled state by the previous company is quite a challenge. This time we moved to Slovakia, where we took on the task of restoring the functionality of the **PowerScreen Warrior 1800** screener from 2009. How did the entire operation go?

### Pre-assembly Diagnostics – Machine Condition Matters

Before we proceeded with the actual engine installation, **it was necessary to thoroughly check the engine compartment, verify the condition of the screws, filter housing, hydraulic pump, and tank.** In such a situation, there is no room for oversight – **every component must be prepared with the utmost care.** The machine had been without an engine for six months, which had been disassembled by the previous team. Unfortunately, the cost of repairs turned out to be higher than purchasing a new unit, so **the client decided to buy a brand new engine**, which we properly reconfigured.

### Perkins Engine in CAT C4.4 Configuration – Reconfiguration and Installation

**The new engine required reconfiguration** because its flywheel housing and front with the hydraulic pump attachment differed from the version used in the machine.

**We replaced the necessary components:**

- flywheel,
- front housing
- and clutch

**All to ensure long and trouble-free operation of the screener.** For the installation of the clutch, we utilized the space in the truck – access there was much easier than in the machine compartment. The screws were secured with adhesive to prevent loosening during operation.

### Tight Spaces – Access and Installation Problems

Due to the limited space under the screener's frame and the lack of appropriate equipment, **the engine installation required unconventional solutions**. Strapping belts and additional maneuvers were employed – all to precisely seat the engine on the mounts and fit it to the brackets.

**The hydraulic pump was installed while adhering to all cleanliness principles** – cutters, screw holes, seals, and sealing mass played a key role here.

In the next stage, we installed the fuel lines, electrical system, and auxiliary hydraulic pump.

### Air Filtration and Final Tests

We also did not forget about the intake system – **the air filter housing was thoroughly cleaned, and then a new filter was installed.**

Depending on the machine's operating conditions, **the filter should be cleaned or replaced even daily** – its efficiency directly affects the engine's durability.

Finally, we topped up the hydraulic oil and checked the battery voltage. **After cleaning the terminals and connecting all systems, the engine was started.**

**All screener functions – driving, belts, feed hopper – worked correctly.**

### Summary

At first glance, the installation of the new engine turned out to be a significant technical challenge, especially due to the lack of prior disassembly in our scope.

**Despite the difficulties, the machine was started, tested, and handed over to the client fully operational** – without leaks and problems.
