Four-Stroke diesel engine overhauling service
We perform engine overhauling projects on a case-by-case basis and as part of a comprehensive engine maintenance program.
Our engineers can provide diesel engine services for the maintenance of medium-speed four-stroke engines:
- Overhauling of cylinder covers including valves, rocker arms, and in situ grinding of seats with unique Chris marine tool
- Overhauling of pistons and inspection of connecting rods
- Renewal of main bearings
- Crankshaft inspection and overhauling
- Camshaft overhauling
- Fuel pumps and rollers overhauling and timing
- Engine block replacement
- Liner honing
To minimize machinery downtime, cost of onboard overhauling and avoiding uncertainties, and low quality of onboard or emergency repairs, Injegov has developed the four-stroke engine parts on exchange concept.
For this reason, for most common diesel generating engine types, we maintain complete cylinder covers, pistons with connecting rods, liners, and fuel pumps in our stock which can be provided on an exchange basis. All parts in our inventory are fitted with new consumables, inspected and tested by our workshop team, and ready for all diesel engine services.
On-exchange engine sets are available for the following engines:
- MAN B&W L23/30H
- MAN B&W L28/32H
- YANMAR N21
- YANMAR N18
- YANMAR EY18

Crankshaft Renewal
At Injegov, we undertake dozens of crankshaft overhauling projects every year. Whether marine or power generation applications at the port and en voyage, crankshaft renewal is a part of our diesel engine services for over 45 years. We have vast experience in preparation requirements and overhaul—inspection procedures, assembly, alignment, re-choking, and engine testing after repairs. By keeping a substantial stock of crankshafts and understanding all the complexities of a crankshaft renewal project, we can assist owners with diesel engine services from start to finish:
- procurement of a new crankshaft
- transportation
- inspection
- overhauling
- accessory and electrical works
- final assembly
- alignment
- testing
Because we understand minimizing asset downtime is critical, we ensure fast delivery times and trouble-free arrangements. Whether in need of a big crankshaft for the main engine, power plant engine, or a small auxiliary generator, we provide customized solutions.

Troubleshooting
You are in need of our diesel engine services!
As an interconnected system, various factors influence the smooth operation of an engine. Despite the effort, time, and resources used for main engines to run continuously, it is often inevitable for a breakdown to occur.
At Injegov, we have the capacity and know-how to trace the root of the breakdown and develop the most appropriate solution.
