Introduction: What Your Transmission is Telling You

The ZF 4BP230 transmission’s electronic control unit (TCU) monitors for faults and reports them via codes on the display. Understanding these codes is the first step to fast, accurate repair. As a 20-year technical expert, Tianjin XiaoHang Construction Machinery Co., Ltd. explains the most common fault codes.

Section 1: The Most Common Fault Codes

A Guide for Technicians

If your machine shows a fault, check this list:

Code “BA” (Filter Clogged): This code indicates that the transmission fine filter is clogged or the sensor circuit has failed. This is a critical warning; you must replace the filter immediately (e.g., Part No. [0501.298.690]) to prevent oil starvation and pump damage.

Codes “B1” through “B6” (Clutch Slippage): These codes indicate that a specific clutch pack is slipping. For example:

B1: Clutch K1 slippage

B2: Clutch K2 slippage

B3: Clutch K3 slippage

B4: Clutch K4 slippage

B5: Clutch KV (Forward) slippage

B6: Clutch KR (Reverse) slippage

Code “3E” (Speed Sensor Failure): This indicates the output speed sensor signal has failed. This requires checking the sensor (e.g., [0501.328.675]) and its wiring.

Introduction: The Precision of Hydraulic Control

The ZF 4BP230 transmission achieves its smooth shifting by using 6 proportional solenoid valves (Y1-Y6)⁴². These valves, located in the HCU (Hydraulic Control Unit), precisely control the 16+2 bar system pressure to engage the 6 clutch packs. Failure of a single solenoid leads to harsh shifting or complete gear loss.

As a 20-year technical expert in ZF transmission repair, Tianjin XiaoHang Construction Machinery Co., Ltd. provides this guide for diagnosing and sourcing these critical electronic parts.

Section 1: Technical Specifications and Diagnosis

Key Data for Technicians

Our 20 years of repair data confirm these key specifications for the 4BP230 solenoids:

• Type: Proportional Solenoid Valve
• Operating Voltage: 24 V
• Resistance (at 20°C): 19 $\Omega$ (Ohms)
• Operating Current: 100 – 500 mA

A technician can diagnose a faulty solenoid by checking its resistance. If the value is far from 19 $\Omega$, the solenoid is damaged and must be replaced⁴⁷.

Section 2: Sourcing Verified Solenoid Valves

The XiaoHang Quality Guarantee

The 4BP230 HCU (part of assembly [4660.159.024]) requires high-quality replacement solenoids. XiaoHang Machinery Co., Ltd. supplies verified proportional solenoid valves that meet the exact 19 $\Omega$resistance and current specifications.

• Fast Lead Times: We maintain a strong inventory of these high-demand electronic components.
• Cost Efficiency: Our China-based supply chain ensures competitive pricing for these high-tech valves.

Conclusion: Restore Your Shifting Quality

Don’t let a faulty solenoid stop your machine. Trust Tianjin XiaoHang Construction Machinery Co., Ltd. for verified 4BP230 proportional solenoids and the technical data to support your diagnosis.

ZF 4BP230 Speed Sensor Failure: A Sourcing Guide for Engine, Turbine, and Output Sensors

Introduction: The Electronic Feedback Loop

The ZF 4BP230 transmission relies on a set of speed sensors to provide crucial data to the TCU (Electronic Control Unit) for smooth shifting and fault detection³⁴. Failure of these sensors is a common fault point that can halt a machine.

This guide from Tianjin XiaoHang Construction Machinery Co., Ltd. helps you accurately source the correct replacement speed sensors for your 4BP230.

Section 1: The Four Critical Speed Sensors

Identifying the Correct Sensor

The 4BP230 system uses four key sensors to monitor speeds:

1. Engine Speed Sensor (B1)
2. Turbine Rotary Sensor (B2)
3. Middle Gear Speed Sensor (B3)
4. Output Speed Sensor (B4)

These are often inductive sensors, and for specific BOMs like 4681.084.018, the part number is [0501.328.675].

Section 2: Technical Specifications and Testing

Expert Verification

Our 20 years of technical expertise confirms that these magnetic-electric (inductive) sensors should have a resistance at 20°C of approximately 1050 $\Omega$ (Ohms) $\pm$10%⁴¹. When troubleshooting, a technician can test the sensor’s resistance to confirm failure before ordering.

Section 3: Sourcing Verified Electronic Components

Servicing CASE Construction Equipment: Sourcing ZF Transmission Spares for Loaders

Introduction: The CASE and ZF Partnership

Many CASE Construction wheel loaders are trusted globally for their performance, which often relies on the durability of an integrated ZF transmission. For distributors and service technicians, identifying the correct ZF model within a CASE machine is the first step to successful parts procurement.

This guide from Tianjin XiaoHang Construction Machinery Co., Ltd. helps you identify and source the correct ZF spares for your CASE equipment, leveraging our 20 years of industry experience.

Section 1: Identifying the ZF Model in Your CASE Loader

Look for the Nameplate

While CASE has its own part numbering system, the transmission itself will have a ZF nameplate (data plate). This plate contains the two most important pieces of information for sourcing:

• Type (Model): e.g., 4BP230, 4WG210, etc.
• Parts List No. (BOM): e.g., 4681.084.018.

You must use these ZF numbers, not the CASE part number, to guarantee accurate aftermarket sourcing.

Section 2: Common Spares for ZF-Equipped CASE Machines

High-Wear Items for Loader Applications

Based on our 20 years of repair data, loaders (like the CASE model shown in ZF training) put heavy stress on:

• Torque Converters: Sourcing the correct unit (e.g., [0501.009.431] for a 4BP230) is vital.
• Clutch Packs (K1-K4, KV, KR): Constant forward-reverse shifting causes wear.
• Sensors and Solenoids: Electronic controls are critical for smooth operation.

Section 3: The XiaoHang Advantage for OEM Brands

China Supply Chain Speed for Global Brands

XiaoHang Machinery Co. is a premier supplier based in China, offering a significant advantage for sourcing ZF parts used in major OEMs like CASE. We provide:
