Overview
The ZF 0730.113.217 SHIM is a precision-engineered OEM genuine spacer component designed to establish critical axial clearances within heavy-duty ZF powershift transmissions. This shim sits between the differential housing and the crown wheel assembly, ensuring that gear mesh patterns remain within factory tolerances. The SKU 0730.113.217 is specifically calibrated for use in construction machinery drivelines, where even a 0.1mm deviation in end-play can lead to premature component fatigue. By maintaining exact preload specifications, this shim directly supports the longevity of the 2099109002: DIFFERENTIAL and the 2099364014: CROWN WHEEL in the final drive assembly.
Symptoms of Failure
- Excessive differential backlash — A worn or incorrectly selected shim causes the 2099209001: DIFFERENTIAL to shift axially, resulting in a clunking noise during load reversals.
- Oil contamination from metal debris — When the shim collapses, the 2098309010: DIFFERENTIAL HOUSING can contact rotating gears, generating fine metallic particles in the transmission fluid.
- Intermittent gear slippage under load — Loss of proper shim thickness alters the preload on the bevel gear set, causing momentary power loss when excavating or grading.
- Vibration at the axle housing — Uneven shim wear leads to misalignment of the differential carrier, transmitting harmonic vibrations through the driveline during high-torque operations.

Compatibility
This shim is engineered for ZF WG-series powershift transmissions commonly found in wheel loaders, telehandlers, and graders. It is a direct fit for the following ZF models: WG180, WG200, WG210, and WG250. The 0730.113.217 is also used in certain ErgoPower and Ecolite drivelines where the differential housing requires a 2.17 mm spacer to achieve correct bearing preload. Always verify the existing shim stack thickness before replacement, as selective fitment may require combining this shim with the 12883200682: THRUST WASHER to achieve the specified end-play.
