4275360880 Original Loader Propelleer Shaft for ZW310-5B

Part number 4275360880 is the original transmission shaft provided by Hitachi Construction Machinery for the ZW310-5B wheel loader. Its universal models usually cover ZW310 series same platform loaders such as ZW310-5A, ZW310-6, ZW330-5B, etc. As the core transmission component of the original factory, its length, spline specifications, and universal joint phase are completely matched with the layout of the vehicle transmission system. It is strictly prohibited to use non original or non matching transmission shafts to avoid transmission noise, vibration, or damage to the gearbox/drive axle.

This product is a transmission shaft assembly with a central spline expansion sleeve. The main body is made of black alloy steel pipe, with universal joint forks welded at both ends, and connected to the flange flange through a cross shaft universal joint. The middle section is integrated with a telescopic sleeve with external splines to compensate for the relative displacement between the axle and gearbox during vehicle operation. The universal joint is lubricated with grease and equipped with an oil injection nozzle. Its core parameters are designed based on the power and load of ZW310-5B: rated torque ≥ 500 N · m, working angle ≤ 15 °, and maximum working speed of about 3000 rpm. The spline pair has undergone high-frequency quenching treatment, resulting in good wear resistance; The overall dynamic balance accuracy is high, ensuring smooth high-speed operation.

Installation specifications: 1 Alignment installation: Before installation, ensure that the transmission output flange is parallel and aligned with the drive axle input flange (deviation ≤ 1.5 °). During installation, ensure that the phase of the universal joint forks at both ends is consistent (i.e. in the same plane). 2. Torque tightening: A torque wrench must be used to tighten the bolts connecting the flanges in a staggered order to the specified torque (usually 120-150 N · m). 3. Lubrication: Immediately add lithium based grease to the universal joint through the oil nozzle after installation, until the old grease is squeezed out of the sealing ring.
