ZF 4WG310 Input Assembly: Sourcing High-Precision Input Shaft 4646.302.106 and Taper Roller Bearings

Introduction: The Core of the Driveline

The Input Assembly of the ZF 4WG310 (Assembly 4646.102.045) contains the most critical rotating components, including the input shaft and high-precision tapered roller bearings. Misalignment or bearing failure here causes complete transmission destruction.

This sourcing guide from Tianjin XiaoHang Construction Machinery Co., Ltd. helps you secure the correct, high-tolerance components for this high-stress assembly.

Section 1: Key Rotating Components

The Input Shaft and Its Supports

The input assembly, often paired with powerful engines, requires precision parts:

1. INPUT SHAFT 4646.302.106: The main power input.
2. HELICAL GEAR 4646.302.128: Transmits drive to the internal gearing.
3. TAPERED ROLLER BEARING 0735.371.862: Two of these precision bearings are required to support the shaft.

Section 2: Sourcing High-Tolerance Bearings

The XiaoHang Precision Standard

Bearing tolerance is paramount. The TAPER ROLLER BEARING 0735.371.862 must meet precise dimensional and load specifications. XiaoHang Machinery Co.’s 20 years of repair expertise ensures our supplied bearings guarantee the long-term rotational integrity of the input shaft.

Section 3: Essential Sealing and Plug Components

Don’t Forget the Small Parts

This assembly also requires specific sealing parts: O-RING 0634.313.867 and various HEXAGON SCREWS (e.g., 0636.015.129) for sealing and mounting the OIL FEED FLANGE 4646.302.140. XiaoHang Machinery Co. provides all these minor parts alongside the major components.
