ZF 0730.007.002 SHIM | OEM Genuine Part

Overview

The ZF 0730.007.002 SHIM is a precision-engineered OEM genuine component designed to establish exact axial clearances within heavy-duty ZF transmissions. This shim sits between the differential housing and the bearing race, ensuring that the gear train maintains proper preload and alignment under extreme torque loads. As a critical adjustment element, the SKU 0730.007.002 directly influences the longevity of surrounding rotating assemblies. When installed correctly, it prevents unwanted movement that can lead to premature wear on adjacent components such as the 5838109012: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING.

Symptoms of Failure

• Excessive differential backlash – When the shim compresses or wears, you will notice a clunking noise during gear engagement, particularly in construction machinery operating under heavy loads.
• Oil leaks near the differential housing – A degraded shim alters the seal compression, causing transmission fluid to seep past the 5838300626: DIFFERENTIAL HOUSING gasket surface.
• Premature bearing failure – Incorrect shim thickness leads to improper preload on the taper roller bearing, resulting in overheating and metallic debris in the oil.
• Gear slippage under load – As axial play increases, the 2093209023: DIFFERENTIAL assembly loses its positional stability, causing intermittent power loss.

Compatibility

This shim is primarily utilized in ZF WG series transmissions commonly found in construction machinery. It is compatible with the following transmission models:

• ZF WG180
• ZF WG200
• ZF WG210
• ZF WG310 (early variants)

Always verify the shim stack height when replacing the 5838300626: DIFFERENTIAL HOUSING or the 0750117075: TAPER ROLLER BEARING to maintain factory tolerances.

Frequently Asked Questions

Q: Can I reuse the ZF 0730.007.002 shim after disassembly?
A: No. This shim is a single-use component. Reusing it can result in incorrect preload and accelerated wear of the 0750117075: TAPER ROLLER BEARING.

Q: How do I measure if I need a different shim thickness?
A: Use a dial indicator to measure the end float of the differential assembly. The target clearance is typically 0.05–0.15 mm. If the measurement falls outside this range, select a shim with the appropriate thickness.

Q: Is this shim compatible with the ZF WG310 transmission?
A: Yes, but only for early production models. Verify the differential housing part number; if it matches 5838300626: DIFFERENTIAL HOUSING, the shim is suitable.
