Overview
The ZF 0730.111.800 SHIM is a precision-engineered OEM genuine part designed to establish the correct axial clearance and preload within ZF heavy-duty transmission assemblies. This shim sits between the differential housing and bearing races, ensuring that gear meshing remains within factory tolerances. The SKU 0730.111.800 is critical for maintaining the structural integrity of the differential unit, preventing unwanted movement that can lead to accelerated wear on adjacent components such as the 2093109029 DIFFERENTIAL and the 0750117075 TAPER ROLLER BEARING. Without this shim, the entire axle assembly risks misalignment, leading to costly downtime in construction machinery.
Symptoms of Failure
- Oil leaks from the axle housing: When the ZF 0730.111.800 shim wears or compresses beyond spec, the differential housing shifts, breaking the seal at the gasket interface and causing visible fluid seepage.
- Gear slipping under load: A worn shim allows excessive end-play in the differential, causing the ring and pinion gears to lose proper contact. This results in intermittent slipping or clunking during acceleration.
- Abnormal whining or grinding noise: Incorrect shim thickness alters the preload on the 0750117075 TAPER ROLLER BEARING, generating a high-pitched whine that worsens as the bearing fails.
- Vibration in the driveline: Loss of shim integrity creates lateral play in the 2093209094 DIFFERENTIAL, transmitting vibration through the axle shafts and into the vehicle chassis.

Compatibility
This shim is engineered for use in ZF WG series powershift transmissions commonly found in construction machinery. It is directly compatible with the following ZF transmission models: WG180, WG200, WG210, WG250, and WG310. It also fits select differential assemblies in the ZF 4WG-200 and 5WG-300 series. Always verify the shim stack height against the 2093309078 DIFF.HOUSING to ensure proper preload on the 2093109029 DIFFERENTIAL assembly.

Frequently Asked Questions
Q: How do I know if the ZF 0730.111.800 shim needs replacement?
A: Measure the differential end-play with a dial indicator. If clearance exceeds 0.15 mm, or if you observe oil weeping from the housing joint, the shim has likely compressed beyond service limits.
Q: Can I stack multiple 0730.111.800 shims to adjust preload?
A: Yes, but only if the total stack height does not exceed 1.6 mm. Always use a new 0631100223 SPRING PIN to secure the stack, and verify that the 0750117075 TAPER ROLLER BEARING rotates freely after assembly.
Q: Is this shim compatible with aftermarket differential housings?
A: The 0730.111.800 is machined to OEM ZF tolerances. For non-OEM housings, we recommend comparing the inner diameter against the 2093309078 DIFF.HOUSING specs to avoid binding.
