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.
