Overview
The ZF 0630.000.190 SHIM RING is a precision-engineered OEM genuine component designed for critical axial clearance adjustment within ZF heavy-duty construction machinery transmissions. This shim ring sits between the planetary gear set and the bearing cover assembly, ensuring correct preload and alignment of rotating elements. As part number 0630.000.190, it functions as a selective-fit spacer that compensates for manufacturing tolerances, preventing unwanted axial movement that can lead to premature wear. When installed alongside the 4108101112: HOUSING and the 4108201177: HOUSING, this shim ring maintains the precise end-play required for optimal gear mesh and bearing longevity.
Symptoms of Failure
- Transmission gear slipping under load – A worn or incorrectly sized shim ring allows excessive axial play, causing gears to lose proper engagement during high-torque operations in excavators and loaders.
- Abnormal bearing noise during deceleration – When the 0630.000.190 loses its dimensional integrity, tapered roller bearings develop looseness, producing a distinct rumbling or grinding sound when the machine slows down.
- Oil contamination from metal particles – A failing shim ring can fracture or wear thin, releasing fine metallic debris into the transmission fluid, often detected during routine oil analysis on construction equipment.
- Intermittent driveline vibration at specific RPM ranges – Loss of proper shim thickness creates harmonic imbalances that manifest as chassis vibration between 1500-2000 RPM during grading or digging operations.

Compatibility
This shim ring is engineered for ZF WG180, WG200, and WG210 series transmissions commonly found in wheel loaders, graders, and dump trucks. It directly interfaces with the 4108301304: BEARING COVER and the 0636302056: SCREW PLUG during assembly. The 0630.000.190 is also compatible with ZF 4WG-180, 4WG-200, and 5WG-210 variants used in Volvo, Liebherr, and Caterpillar construction machinery. Always verify the existing shim thickness before replacement, as selective-fit adjustments may require a different thickness variant.
