Learn how endoscopy of MWM engines helps you to save your money and time

Engines are a key component of MWM gas gensets. Their maintenance is time-consuming, while downtime and unplanned breakdowns may involve expenses on repairs.

Using an endoscope allows for a thorough inspection of hard-to-reach areas and engine parts as well as quickly locate hidden internal defects.

Remote visual-optical inspection reveals carbon building up, scratches, scuffs, corrosion, cracks, leakages, deposits on the components without disassembling them.

We use two types of endoscopes for this purpose: optical and videoscope. The devices send a clear image of the damage to the screen, which helps to assess the condition of the engine without any distortions or without having to disassemble it.

What are the consequences of negligence towards MWM engines and how are they identified with the help of an endoscope:

1. Inspection of combustion chambers of engine cylinders during E40 maintenance to assess the condition of the cylinder liner, piston, cylinder head surface, valves.

During engine operation, there is a chance of the formation of carbon deposits. Its untimely removal leads to knocking and high temperatures in the engine: carbon buildup falls off and leaves scratches on cylinder liner and piston.

Failure to replace the liner and piston rings on time may result in their critical wear and tear. This leads to the formation of heavy oil deposits on the surface of the engine piston.

2. Failure hunting and engine monitoring.

Piston ring destruction resulted in damage to the surface of the cylinder liner, which caused scuffs on it (TCG 2032 engine)

3. Engine condition assessment following a long-term storage, downtime or transportation.

Improper engine storage is accompanied by rapid change of temperatures, causing condensation to appear in the cylinder, which leads to corrosion on the surface of the liner and in the engine mixture cooler.

Storage of the engine unprotected in the open air leads to rainwater entering the cylinders through the exhaust pipe.  As the result, initiation of corrosion on the cylinder head and liner surfaces.

4. Search for other malfunctions of the engine and plant components in hard-to-reach areas: coolant or oil leakages, contamination of oil cooling radiators, damage to camshaft cams, catalyst damage.

Due to the use of low-quality oil and nonobservance of its replacement intervals, the catalyst becomes clogged with soot, melts and cracks.

Exhaust heat exchanger pipe breaks and leaks due to exceeding its expected service life.

A leaking clamp causes the liquid to drip onto the flywheel and flange for a long while: eventually corrosion will form and the bolts will break.

Using coolant of poor quality results in oil overheating and the formation of deposits on the engine oil cooling radiator.

Using an endoscope allows you to assess the condition of the engine with a high level of accuracy as well as helps you to detect malfunctions without a time-consuming and expensive procedure for dismantling the components of the engine.

By entrusting the repair of engines to Motorwerk-SGU, LLC – an official Service Partner of MWM in Russia, you get a high-quality result thanks to a team of qualified engineers and mechanics, as well as considerable savings in time and money.
