Description
Product Overview
Under long-term high-temperature, high-pressure, and heavy-load operating conditions of the heavy-duty C15/C18 diesel engine, the rubber sealing rings in the injector components will harden, shrink, and crack, resulting in diesel leakage at the cylinder head installation position, continuous pressure loss inside the cylinder, and difficulties in cold start, insufficient power, black smoke from the exhaust, and increased carbon deposits in the cylinder. This set of repair kit integrates all the sealing points of the injector exterior and interior components. During disassembly and major repair, the entire set is replaced, eliminating the cumbersome process of separately matching gaskets and rubber rings, significantly reducing the repair time and being suitable for the maintenance of C15/C18 power injectors in mining machinery, heavy trucks, and large power generation units.
Unique Accessories of the Exclusive Set
Black sealing rubber ring with an irregular wave contour, providing a complete seal on the end face of the injector housing
One-piece irregular-shaped rubber pad, precisely matching the contour of the upper cover shell of the injector, with no assembly gap after assembly, and preventing high-pressure fuel from leaking from the joint surface of the housing after locking, resistant to high temperatures and not prone to aging and cracking.
Multiple-sized colored high-temperature and oil-resistant O-rings, meeting the sealing requirements of all points
The kit includes red, brown, and blue O-rings of various sizes, respectively suitable for all sealing points such as the valve stem, oil circuit connector, and installation base of the injector; made of fluororubber material, resistant to long-term high-temperature and diesel corrosion in high-pressure conditions, and less prone to shrinking and leaking.
Red integrated plastic oil circuit protection plug, preventing dust and impurities during maintenance
Complementary red solid plastic plug, sealing the precise micro-pores of the injector nozzle during maintenance and disassembly, preventing sand, metal debris from entering the valve core and causing jamming, protecting the precise nozzle during assembly and storage, and reducing the probability of installation faults.
The entire set of accessories has precise dimensions that match without the need for grinding and adaptation
All sealing components are produced according to the mold standards of the C15 and C18 engine injector cavities and installation slots, directly replacing and installing without any size deviations or assembly不到位 rework issues， making the repair simple and easy.
Fluororubber material is resistant to aging and suitable for heavy-load and high-temperature conditions
All colored O-rings are made of high-temperature-resistant fluororubber raw materials， with stronger high-temperature and diesel corrosion resistance than ordinary nitrile rubber， significantly extending the service life in 24-hour continuous heavy-load conditions in the mining area. Applicable scenarios
This product is suitable for heavy-duty freight trucks equipped with C15 and C18 diesel engines, large mining excavators, heavy loaders, high-power stationary diesel generators. It is applicable to mining areas and construction sites for 24-hour full-load operation under high temperature and high dust conditions. It is suitable for major overhauls of heavy-duty diesel fuel injection systems.
