4697283 Excavator Filter element for EX2600-6

Part number 4697283 is a genuine oil filter produced by Hitachi Construction Machinery Co., Ltd. in Japan. This component is the core filtering unit of the engine lubrication system. Its universal model is mainly suitable for Hitachi's ultra large mining equipment equipped with high-power diesel engines. This filter is highly suitable for EX2600-6, EX3600-6, EX2600-7 and other series of ultra large mining excavators. To ensure that everything is foolproof, it is strongly recommended that you verify the final compatibility with Hitachi official or authorized dealers through the device body serial number before procurement and installation.

This product is a rotary type full flow oil filter, with a prominent bright yellow engineering plastic shell and a brown metal end cap on the top. The surface is printed with the "HITACHI" brand logo, the words "OIL Filter", and part number 4697283. Internally, high-performance composite filter paper (a mixture of cellulose and fiberglass) is used to increase the filtration area with a star shaped folding structure. The filtration accuracy is usually 20-30 microns, which can efficiently intercept metal debris, carbon deposits, and gum in engine oil. The filter element is equipped with a check valve (to prevent oil backflow after engine shutdown) and a bypass valve (to open when the filter element is clogged or the oil is viscous at low temperatures, ensuring continuous oil supply). Top integrated oil resistant rubber sealing ring ensures 100% sealing after one installation. Its working pressure range is usually 0.1-1.0 MPa, and its temperature resistance range is -30 ℃ to+120 ℃, which can meet the lubrication needs of large diesel engines under harsh working conditions.

Replacement cycle: Strictly follow the maintenance standard of replacing every 500 working hours or every 6 months (whichever comes first). In mining, dusty, and continuous heavy load conditions, it is recommended to shorten the working hours to 300. Replacement steps: 1 Heat engine pressure relief: Start the engine to normal operating temperature and then turn off the engine to allow oil flow and release system pressure. 2. Disassemble old parts: Place an oil pan under the filter and use a special filter wrench to unscrew the old filter counterclockwise. 3. Cleaning and preparation: Wipe the installation surface of the filter seat on the engine with a clean cloth. Apply a uniform layer of new engine oil on the rubber sealing ring at the top of the new filter. 4. Installation: Use your hand to screw the new filter into the base until the sealing ring contacts the base, then use a tool to tighten 3/4 to 1 turn (approximately 20-25 N · m). Excessive tightening is strictly prohibited.
