1677252371 Original Loader Oil Seal for ZW150

Part number 1677252371 is a genuine oil seal produced by Hitachi Construction Machinery in Japan. This component is an oil seal for the rotating shaft of the lubrication system. Its universal models usually cover ZW150 series wheel loaders such as ZW150-5, ZW150-6, ZW160-5B, which may be suitable for key rotating shaft parts such as engine crankshafts, transmission output shafts, and wheel reducers that require prevention of oil or gear oil leakage.

This product is an oil seal for exposed skeleton type rotating shafts. The main body is made of black elastic material (usually nitrile rubber NBR or fluororubber FKM), with a sturdy metal skeleton built in to maintain shape stability and provide support after being pressed into the installation hole. There is a spiral or wavy oil return line at the lip, which can pump the leaked oil back into the box, thereby improving the sealing effect. The inner diameter, outer diameter, and thickness are customized according to the specific installation position. For example, the inner diameter of the oil seal suitable for the drive axle hub is usually in the range of 80-120mm. The working temperature range is about -30 ℃ to+150 ℃, which can withstand long-term immersion in engine oil, gear oil, and lubricating grease, and has a certain ability to resist abrasive wear.

Installation specifications: 1 Cleaning: Before installation, the shaft neck, bearing seat hole, and oil seal installation groove must be thoroughly cleaned with non-woven fabric and cleaning agent to ensure that there are no metal burrs, oil stains, or residual old seals. 2. Lubrication: Apply an appropriate amount of lubricating grease compatible with the system between the main lip and dust lip of the oil seal. 3. Positive pressing: A dedicated installation sleeve or core shaft must be used to ensure that the oil seal is absolutely vertically and smoothly pressed into the installation hole until it is fully in place. It is strictly prohibited to directly strike the metal frame of the oil seal with a hammer to avoid deformation.
