Sourcing ZF 4BP230 Power Take-Off (PTO) Components: Pump Shaft 4681.354.001

Introduction: The Auxiliary Power Source

The Power Take-Off (PTO) unit on a ZF 4BP230 (Assembly 4681.154.001) is a critical feature, allowing the machine to power auxiliary hydraulic pumps (e.g., for steering or implements). Failure of the PTO drive shaft can halt all auxiliary functions.

This guide from Tianjin XiaoHang Construction Machinery Co., Ltd. focuses on the procurement of key PTO internal components.

Section 1: Key PTO Components for Sourcing

Inside the PTO Assembly

The 4BP230 PTO is a high-torque component. When servicing this assembly, key replacement parts include:

1. PUMP SHAFT 4681.354.001: The main drive shaft for the auxiliary pump.
2. BALL BEARING 0735.372.298: The primary bearing supporting the shaft.
3. RETAINING RING 0630.502.040 and R-RING 0634.402.557: Critical for holding the assembly.
4. O-RING 0634.304.616: The main seal (130X3) for the cover plate.

Section 2: Sourcing for High-Torque Applications

Quality Assurance on Shafts and Bearings

The PUMP SHAFT 4681.354.001 must be made from high-strength, properly hardened steel to withstand continuous torque. XiaoHang Machinery Co.’s 20 years of expertise ensures that the PTO components we supply meet these rigorous metallurgical standards, preventing premature spline wear or shaft failure.

Section 3: The XiaoHang Advantage: Specialized Inventory
