Eagleharm 101: Our Engine Reconditioning Process

Any industrial engine mechanic can take an engine apart and put it back together, but what about reconditioning an engine to an almost ‘good as new’ level? When it comes to industrial engines, down time equals money lost. Want to see how an industrial engine should be reconditioned? Here’s our Eagleharm Engineering engine reconditioning process…

Step 1: Engine Dismantle

The first step in our engine reconditioning process is one of the most important. This is where we carefully dismantle the industrial engine, looking at the condition of each and every engine part as it is removed. Once the engine has been stripped, each individual part is carefully stored for step two – the cleaning process.

Step 2: Cleaning Engine Parts

Once the industrial engine parts have been assessed for wear and damage, they are ready for the cleaning phase. Each part is placed in our Eagleharm Ultrasonic Cleaner which utilises Ultrasonic technology to remove oil, dirt and grime – leaving each part almost good as new. Once thoroughly cleaned, the industrial engine parts are assessed once more.

Step 3: Bearing Clearances

The next phase in the engine reconditioning process is to check bearing clearances. Here, our qualified artisans inspect the engine parts and compare them to the manufacturer’s factory specifications. Parts that are too damaged to salvage are discarded and replaced, and parts that can be saved are machined back to factory specification.

Step 4: Engine Reassembly

Once we’ve machined the salvageable parts to factory spec, and replaced the non-salvageable parts with new ones, it’s time to put the industrial engine back together again. Before this happens, each part is assessed once more to ensure they meet the manufacturer’s requirements.

Step 5: Testing the Engine

Probably the most important step in our engine reconditioning process, the final phase is to test the reconditioned engine. Here we listen carefully for any irregularities and run the engine to ensure it is functioning optimally. If nothing serious comes up, the industrial engine is ready for work once more!
