ZF 4BP230 HCU Repair: Sourcing Internal Valve Block Components (Pressure Regulator 0501.335.152)


Introduction: Deep Repair of the Hydraulic Control Unit (HCU)
When a ZF 4BP230 suffers from hydraulic control issues, the fault often lies within the Valve Block (part of Assembly 4660.159.024). Instead of replacing the entire expensive assembly, a skilled technician can repair it by replacing the internal components.
As a 20-year technical expert, Tianjin XiaoHang Construction Machinery Co., Ltd. supplies the high-precision internal components required for HCU overhaul.
Section 1: Key Internal Components for HCU Repair
Sourcing Beyond the Solenoid
The HCU contains numerous precision parts that wear over time:

- CONTROL PISTON 4660.359.015: (Quantity 6)
- COMPRESSION SPRING 0732.300.232: (Quantity 6)
- O-RING 0634.306.522: (Quantity 6, size 11X2)
