Overview
The ZF 0730.002.162 SHIM is a precision-engineered spacer component designed for the WG92 and WG98 transmission series. This OEM genuine part sits between the main transmission housing and the rear cover assembly, where it establishes the critical axial clearance for the planetary gear sets and bearing preload. By maintaining exacting tolerances, the shim ensures that rotating assemblies remain properly aligned under load. The SKU 0730.002.162 is manufactured from high-strength steel to resist deformation during thermal cycling and high-torque operation. When installed alongside the 4660101015: TRANSMISSION HOUSING, this shim prevents metal-to-metal contact that would otherwise accelerate wear on adjacent components.
Symptoms of Failure
- Transmission oil seepage at rear cover joint — A worn or crushed shim allows the housing faces to shift, breaking the seal and causing slow oil leaks that leave puddles under the bell housing.
- Intermittent gear slipping under load — When the shim loses its original thickness, planetary gear end-play increases, leading to momentary loss of torque transfer during uphill climbs or heavy hauling.
- Metallic grinding noise from transmission center — Excessive axial movement from a collapsed shim causes gear teeth to contact housing walls, producing a distinct grinding sound that worsens in lower gears.
- Delayed engagement when shifting from Neutral to Drive — Insufficient shim height reduces clutch pack clamping force, creating a hesitation of 2-3 seconds before the transmission responds.

Compatibility
This shim is engineered for the ZF WG92 and WG98 transmission families, which include the WG180, WG200, WG210, and WG250 models. It is also used in certain WG120 variants produced after 2005. The part directly interfaces with the 4660301054: HOUSING II and must be paired with the correct 0631306174: CYLINDRICAL PIN to ensure proper alignment during reassembly. For identification purposes, the 0769123894: TYPE PLATE should be consulted to verify the exact transmission variant before ordering.
