Maintenance and spare parts

The good operation of a diesel engine requires the cooperation of all parts, but some parts are more important to the operation ability of the diesel engine. Frame, frame, cylinder head, connecting rod, piston and crankshaft are usually called large parts because their performance has the greatest impact on the performance of diesel engine, and is the most core, complex and expensive. Therefore, we are consistently exploring fast and more economic ways to maintain these components, including preventive testing technology.

ENGINE REPAIR


The company provides solutions for the technical requirements and application problems of various ships, and can provide professional, fast and reliable technical support and maintenance services for the main engine and auxiliary equipment of the ship and the factory. We provide minor overhaul services, solve electrical problems, replace crankshaft, cylinder block, even the whole engine, test, inspect and repair fuel system components, and replace worn parts before they are damaged.
In the past ten years, we have been specialized in the overhaul and maintenance of man B & W man, Wartsila, Wartsila, Yanmar, Yama, Daihatsu, cat Carter, Mak mark, Cummins Cummins and other famous brands. We also provide original parts and OEM spare parts for field engineers.

Cylinder Cover Welding

The company restored the cylinder head to standard size by welding the corroded or worn sealing seat surface and sealing surface, and promoted the repair of four stroke cylinder head to a higher level.
After using for a period of time, the cylinder head will be corroded by the exhaust socket groove, and the cooling water will start to leak to the engine, and the exhaust gas will enter the cooling system.
For mild corrosion, machining enlarges the grooves until the first, second, or third increase, but eventually ends.
If handled properly, the repair area is liquid and gas sealed. We have successfully applied water pressure of up to 12 bar (174 psi) to specimens repaired by metal stitching.
We have developed a program for welding grooves to restore them to their original size and have full functionality.

Line Boring


We can drill almost any cylindrical or tapered inside diameter, from 100 mm to 500 mm. We are able to drill to a maximum depth of about 3 meters, which means that we can handle almost any type of four stroke cylinder liner because there is no line drill that is as versatile, accurate and efficient as we require to provide the highest quality. Our tools are very advanced, compact, low transportation costs, and can work in very tight places.

Crankshaft Straightening/Peening
We can drill almost any cylindrical or tapered inside diameter, from 100 mm to 500 mm. We are able to drill to a maximum depth of about 3 meters, which means that we can handle almost any type of four stroke cylinder liner because there is no line drill that is as versatile, accurate and efficient as we require to provide the highest quality. Our tools are very advanced, compact, low transportation costs, and can work in very tight places.


When the crank pin or main journal of a four stroke engine crankshaft is overheated, it may bend under the influence of the thermal stress contained in the bearing failure. The correctness check of the crankshaft will show if the crankshaft is bent.
It is usually possible to straighten the crankshaft locally without removing it from the crankcase. This process is called "shot peening";. This is a cold working process in which a small force is repeatedly applied in the correct position to return the shaft to its original straightness.

In addition, we can also provide maintenance and overhaul of main engine and auxiliary engine
Disassembly and assembly of all engine units
Exchange and measurement of main bearing
Overhaul and repair of turbocharger
Inspection and repair of fuel pump
Inspection and test of fuel injector
Inspection and repair of engine components Horning (also on site) cylinder liner diameters range from 100 mm to 500 mm.
Seat machining (also on site)
Shock absorber maintenance
Governor overhaul (on board or workshop)
Maintenance of air cooler and oil cooler
Ultrasonic cleaning of parts weighing up to 6000kg
Laser controlled calibration
Electrical engineering, troubleshooting and maintenance Complete crankshaft condition assessment (also on site)
Including hardness test and straightness of pin

SPARE PARTS

We provide all kinds of original and OEM specified spare parts for man B & W man, Wartsila, Wartsila, Yanmar, Yama, Daihatsu, cat Carter, Mak mark, Cummins Cummins and other famous marine engines. We keep some stock of vulnerable goods and buy them directly from licensed engine manufacturers. This service provides our customers with spare parts whenever and wherever they are needed in the world.
 In addition, we are responsible for all the logistics required to transport spare parts from the warehouse to the ship. No matter where the ship is, we can provide service day and night. For all domestic and foreign transportation, we pack all heavy and large parts in wooden cases to ensure that the parts will not be damaged during transportation. All of these boxes are handled in accordance with the international standard ispm-15. If you have any special questions, please contact the sales representative in our office.
