4629717 Original Excavator Oil Filter for ZX200-5A

The part number 4629717 you mentioned is the correct part number for the original oil filter provided by Hitachi for the ZX200-5A hydraulic excavator. This is usually the same series (such as ZX200-5G, ZX210, etc.) or different batches of oil filters. The universal model of this component clearly covers the ZX200-5A model and is the core maintenance part of the engine lubrication system. The use of non original parts is strictly prohibited to avoid poor oil filtration and abnormal engine wear.

This product is a rotary full flow oil filter with a metal outer shell and a high-performance composite filter material (such as a mixture of cellulose and fiberglass) used internally. It has high filtration accuracy (usually able to intercept particles of 20-30 microns) and high pollutant holding capacity. The filter is equipped with an integrated check valve (to prevent oil backflow after engine shutdown, which may cause oil shortage during startup) and a bypass valve (to open when the filter element is clogged or the oil is viscous at low temperatures, ensuring continuous oil supply). There is an oil resistant rubber sealing ring at the top end cover to ensure absolute sealing after one-time installation. Its working parameters are perfectly matched with the engine lubrication system, which is a key barrier to protect the engine and extend its lifespan.

Replacement cycle: Strictly follow the maintenance standard of replacing every 500 working hours or every 6 months, and shorten the cycle in harsh working conditions. Replacement steps: 1 Heat engine pressure relief: Start the engine to operating temperature and then turn off the engine to allow the oil to flow and remove impurities. 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 (4629717). 4. Installation: Use your hand to screw the new filter into the base until the sealing ring contacts the base, and then use a tool to tighten it by 3/4 turn (about 20-25 N · m).
