ZF 0630.004.069 SHIM RING for WG150 | OEM Genuine Part

Overview

The ZF 0630.004.069 SHIM RING is a precision-engineered adjustment component designed for the WG 150 series transmissions. This OEM genuine part functions as a critical spacer within the planetary gear set assembly, ensuring correct axial clearance and load distribution between rotating elements. The SKU 0630.004.069 sits directly against the transmission housing to maintain proper gear mesh alignment and prevent metal-to-metal contact during high-torque operations. When installed alongside the 4642101108: TRANSMISSION HOUSING or the 4642301208: TRANSMISSION HOUSING, this shim ring establishes the foundational spacing required for reliable power transfer.

Symptoms of Failure

When the ZF 0630.004.069 SHIM RING wears beyond tolerance, operators typically encounter these specific failure indicators:

• Excessive axial play in the output shaft – A worn shim ring allows the gear train to shift laterally, producing a noticeable clunking sound during acceleration or deceleration.
• Premature bearing fatigue – Incorrect clearance forces bearings to operate outside their designed load zone, leading to rough rotation and metallic grinding noises.
• Intermittent gear slipping under load – As the shim ring compresses unevenly, gear engagement depth fluctuates, causing momentary power loss during hill climbs or heavy hauling.
• Contaminated transmission fluid with metallic particles – Abrasion between the shim ring and adjacent components generates fine steel debris visible during oil changes.

Technical Specifications

Compatibility

This shim ring is primarily specified for the ZF WG 150 series, but its dimensional profile also suits the WG 180 and WG 200 transmission families when used in conjunction with the correct 0730365125: TYPE PLATE for model verification. The part interfaces directly with the 0631311009: GROOVED STUD to secure positioning within the gear cluster. Applications include ZF 4WG-150, 5WG-150, and certain 6WG-150 variants used in municipal trucks, construction loaders, and agricultural tractors. Always cross-reference the transmission serial number against the type plate before installation.
