8941332075 Original Excavator Oil Filler Cap for ISUZU ENGINE 4JG1 6WG1

The original fuel cap (part number 894133075) is designed specifically for excavators equipped with ISUZU 4JG1 and 6WG1 series diesel engines. It is mainly used to seal the engine crankcase or oil filling port to prevent foreign objects such as dust and moisture from entering. This component is commonly found in small and medium-sized excavators equipped with these two engines, such as Hitachi ZX60, ZX70, ZAX60, ZAX70, and Sany SY75C-9 models. As a genuine original accessory, its universal number 894133075 is the only identifier that ensures it matches perfectly with the threads and gaskets of the engine cylinder head or oil pan filling port. Please provide the specific model and engine number of the host for verification when placing an order.

This product is usually made of high-strength engineering plastics (such as fiberglass reinforced PA66) or die cast aluminum alloy, with oil resistant rubber or fluororubber sealing rings embedded inside to ensure reliable sealing even in high engine temperatures (about 100-120 ° C) and vibration environments. Its structure is mostly threaded or snap in type, with anti slip rolling patterns or protruding ears on the surface, making it easy to manually tighten. Some models may integrate pressure/vacuum valves to balance the air pressure inside and outside the crankcase, preventing oil leakage or dust inhalation. The cover is often labeled with the "OIL" or engine brand logo, and the material should be resistant to oil, diesel, and UV aging, suitable for the dusty and humid working environment of construction machinery.

It is recommended to check the sealing ring of the fuel cap for hardening, cracking, or deformation every 250 hours of work or once a month, and clean the oil and soil on the cap body and threads. Special wrenches or manual operations should be used during disassembly to avoid damaging the threads with excessive force. Before installation, a small amount of engine oil should be applied to the surface of the sealing ring, and then tightened according to the torque specified in the maintenance manual (usually 15-25 N · m) to ensure a seal but not too tight. If the sealing ring loses its elasticity or the cover has cracks or thread wear, it should be replaced with 894133075 original parts in a timely manner. Avoid using sharp tools to pry open the cover in daily life, and keep it dry and away from light during storage. Regular maintenance can prevent oil pollution and leakage, ensuring the cleanliness of the engine interior.
