ZF 4460.308.114 SHIM RING for WG200 | OEM Genuine Part

Overview

The ZF 4460.308.114 SHIM RING is a precision-engineered spacer component designed for the WG 200 series of heavy-duty automatic transmissions. This OEM genuine part, identified by SKU 4460.308.114, sits between the planetary gear set and the output shaft housing to establish critical axial clearance. By maintaining exact end-play tolerances, the shim ring prevents gear train binding and ensures smooth torque transfer under high-load conditions. When installed alongside the 4460165051 CONSOLE and the 4460368311 CONSOLE, this shim ring completes the bearing preload assembly that governs rotational stability.

Symptoms of Failure

• Transmission gear slipping under load — A worn or collapsed shim ring allows excessive axial movement, causing clutch packs to lose engagement pressure during acceleration.
• Low-frequency rumbling from the output housing — When the shim ring degrades, planetary gears contact the case wall, producing a distinct metallic grinding noise at highway speeds.
• Oil leaks at the rear seal interface — Incorrect shim thickness shifts the output shaft position, distorting the seal lip and allowing ATF to weep past the 0636011429 HEXAGON SCREW fasteners.
• Erratic shift timing — Axial play from a failed shim ring disrupts governor pressure signals, causing delayed or harsh shifts between forward gears.

Technical Specifications

Compatibility

This shim ring is engineered for the ZF WG200 transmission family, including the WG180, WG200, and WG210 variants used in municipal buses, fire trucks, and off-highway equipment. It also fits select ZF Ecomat 4HP and 5HP series where the output shaft bearing preload specification matches the 1.14 mm thickness. Always verify clearance using the 0730100365 WASHER as a reference gauge during installation. For WG200 rebuilds, this part must be paired with the correct 4644105418 DISCONNECTION sleeve to prevent oil starvation.
