ZF 0730.112.571 SHIM | OEM Genuine Part

Overview

Precision shimming is critical for maintaining correct axial play and gear mesh within heavy-duty ZF drivetrains. The ZF 0730.112.571 SHIM is a genuine OEM component designed to fill the exact clearance between bearing races and gear faces in the differential assembly. This shim, identified by SKU 0730.112.571, sits directly behind the bearing cup to preload the differential carrier, ensuring that torque transfer remains smooth under extreme loads. Without this specific shim thickness, the entire rotating assembly can shift, leading to premature wear on surrounding components such as the 5838109012: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING.

Symptoms of Failure

When the ZF 0730.112.571 shim wears or collapses, the transmission exhibits distinct failure modes that operators should recognize immediately:

• Excessive differential backlash – A clunking noise when shifting between forward and reverse, indicating the shim has lost its original thickness.
• Oil leaks at the axle housing seal – Worn shims allow the differential to walk laterally, pushing oil past the seal. This is a common “ZF transmission oil leak” search query.
• Premature bearing failure – Incorrect shim stack height causes the taper roller bearing to run at improper preload, generating heat and metallic debris in the oil.
• Gear tooth pitting or chipping – Misaligned ring and pinion gears due to a collapsed shim create uneven contact patterns, often flagged as “differential whine under load.”

Technical Specifications

Compatibility

This shim is engineered for ZF heavy-duty powershift transmissions commonly found in construction machinery. It is a direct fit for the following transmission models: ZF WG180, ZF WG200, ZF WG210, and ZF WG310. These units use the shim to set the preload on the differential carrier assembly. When rebuilding the differential, always pair this shim with a new 2093209023: DIFFERENTIAL and inspect the 5838300626: DIFFERENTIAL HOUSING for wear on the shim seat surface.

Frequently Asked Questions

Q: Can I reuse the ZF 0730.112.571 shim during a rebuild?
A: No. Shims are single-use components because they crush and conform to the bearing seat during initial torque. Reusing a shim will result in incorrect preload and rapid bearing failure.

Q: How do I know if I need a thicker or thinner shim?
A: Measure the differential housing face-to-bearing cup distance with a depth micrometer. The shim thickness (0.50 mm) is the starting point; adjust by ±0.10 mm increments until the rotating torque of the differential falls within the ZF service manual specification.

Q: Is this shim compatible with the ZF WG180 transmission?
A: Yes. The 0730.112.571 is the standard service shim for the WG180, WG200, and WG210 differential carriers. Always verify the part number against your transmission’s serial number plate.
