ZF 0730.003.448 SHIM for WG150 | OEM Genuine Part

Overview

The ZF 0730.003.448 SHIM is a precision-engineered spacer component designed specifically for the WG150 series transmission. This OEM genuine part serves as a critical adjustment element within the planetary gearset assembly, ensuring correct axial clearance and load distribution between rotating components. By maintaining precise tolerances, the 0730.003.448 shim prevents metal-on-metal contact and supports optimal gear mesh alignment. This shim is typically installed during transmission rebuilds or when replacing adjacent components like the TRANSMISSION HOUSING or TRANSMISSION HOUSING, where end-play adjustments are essential for long-term durability.

Symptoms of Failure

• Excessive axial play or end float in the output shaft – When the 0730.003.448 shim wears or compresses beyond tolerance, noticeable movement develops in the driveline, causing vibration during acceleration.
• Low-frequency gear whine or rumbling noise – A worn shim allows gear teeth to misalign, producing a distinct hum that intensifies under load, often mistaken for bearing failure.
• Intermittent gear slipping under heavy torque – Insufficient shim thickness reduces clutch pack clamping force, leading to momentary power loss during uphill climbs or towing.
• Metallic debris in transmission fluid – As the shim deteriorates, fine steel particles contaminate the oil, which can clog the SCREEN SHEET and accelerate wear on other internal parts.

Technical Specifications

Compatibility

This shim is engineered for the ZF WG150 series, but its dimensional profile also suits the WG180 and WG200 models due to shared planetary carrier designs. It is frequently used in WG150-3, WG150-4, and WG150-5 variants. When servicing these transmissions, always pair the shim with a new GROOVED STUD and verify housing alignment using the TYPE PLATE for correct model identification. For WG200 applications, consult the service manual for possible thickness adjustments.
