1112810380 Original Excavator Oil Radiator Cap for ISUZU ENGINE 6BG1

The original oil radiator cap (part number 1112810380, also commonly written as 1-11281038-0) is designed specifically for Hitachi excavators equipped with the ISUZU 6BG1 engine to seal the end cap of the oil cooler (radiator). This component is mainly suitable for Hitachi EX200-5, EZX200-5, ZX200, ZX230, ZX270 and other 20-27 ton medium-sized excavators. As a genuine original accessory, its universal number 1112810380 is the only identifier that ensures a perfect match with the oil cooler housing, gasket, and fixing bolt holes. Please provide the specific model and engine number of the host for verification when placing an order.

This product is usually cast from high-strength aluminum alloy or cast iron, with an internal oil passage and a precision machined surface to ensure flatness and sealing with the cooler housing. Its core function is to cooperate with sealing gaskets (mostly oil resistant rubber or metal gaskets) to seal the oil chamber of the oil cooler, prevent high-pressure oil leakage, and guide the oil to flow through the cooling core for heat exchange. The cover is usually designed with bolt mounting holes and fixed with bolts of a specified torque (usually 40-60 N · m). Its material needs to withstand the high temperature of engine oil (about 100-130 ° C) and system pressure (usually 0.3-0.6 MPa), and have good corrosion resistance to adapt to the harsh working environment of construction machinery.
