ZF 0730.109.411 SHIM | OEM Genuine Part

Overview

Precision shimming is critical for maintaining proper gear mesh and bearing preload within heavy-duty ZF transmissions. The ZF 0730.109.411 SHIM is an OEM genuine part engineered to establish exact axial clearances in the differential assembly of construction machinery drivelines. This thin, hardened steel shim sits between the bearing race and housing to compensate for manufacturing tolerances and wear, ensuring that the 5838109012: DIFFERENTIAL rotates with zero unwanted play. The SKU 0730.109.411 is a factory-specified thickness shim that must be selected during rebuild to restore factory crush and load distribution. Without this precise spacer, the entire gear train experiences misalignment, leading to premature failure of adjacent components.

Symptoms of Failure

• Excessive differential backlash when turning – A worn or incorrect shim causes the ring gear to drift away from the pinion, producing a clunking noise during load reversal. This is a common long-tail search query for “ZF transmission clunking on turns.”
• Oil seepage from the axle housing seal – When the shim collapses or deforms, the 0750117075: TAPER ROLLER BEARING loses its preload, allowing the shaft to wobble and push lubricant past the seal. Technicians often search for “ZF differential oil leak repair.”
• Vibration under load at low speeds – A missing or crushed shim creates uneven tooth contact between the bevel gears, transmitting harsh vibration through the chassis. This symptom is frequently reported as “ZF WG transmission vibration in first gear.”
• Metal debris in the transmission oil filter – As the shim fails, the 2093209023: DIFFERENTIAL gears begin to wear against each other, shedding fine metallic particles into the sump.

Technical Specifications

Compatibility

This shim is designed for use in ZF heavy-duty powershift transmissions commonly found in wheel loaders, graders, and dump trucks. It is a direct fit for the differential carrier assembly in the following ZF models: WG180, WG200, WG210, and WG250. The 0730.109.411 shim is also used in certain ZF 4WG-200 and 6WG-250 transmissions where the 5838300626: DIFFERENTIAL HOUSING requires precise axial adjustment. Always verify the existing shim thickness before ordering; this 0.41 mm variant is one of several available thicknesses in the ZF shim kit.

Frequently Asked Questions

Q: How do I know if the 0730.109.411 shim is the correct thickness for my rebuild?
A: Measure the existing shim stack or the bearing preload gap with a dial indicator. The 0.41 mm shim is a common starting point for WG180/200 transmissions, but always compare against the factory service manual specification for your exact model.

Q: Can I reuse the old shim if it looks undamaged?
A: No. ZF recommends replacing all shims during a differential overhaul because the hardened steel can take a permanent set under load. A reused shim will not restore the precise preload required by the 0750117075: TAPER ROLLER BEARING.

Q: Will this shim fit the ZF 4WG-200 transmission?
A: Yes, the 0730.109.411 is compatible with the 4WG-200 differential housing. However, you must also inspect the 5838300626: DIFFERENTIAL HOUSING for wear at the shim seat before installation.
