ZF 0730.112.572 SHIM | OEM Genuine Part

Overview

The ZF 0730.112.572 SHIM is a precision-engineered OEM genuine part designed to establish critical axial clearances within the differential assembly of heavy-duty construction machinery transmissions. This shim sits between the differential housing and the bearing race, ensuring optimal preload on the 0750117075: TAPER ROLLER BEARING and the 5838109012: DIFFERENTIAL assembly. By maintaining exact tolerances, the SKU 0730.112.572 prevents gear backlash and ensures uniform load distribution across the drivetrain. Without this specific shim, the entire differential unit risks misalignment, leading to accelerated wear on adjacent components.

Symptoms of Failure

When the ZF 0730.112.572 SHIM wears or is incorrectly installed, operators will notice distinct performance issues. Look for these specific failure symptoms:

• Excessive differential backlash — A clunking noise during direction changes indicates the shim has lost its thickness, allowing the 2093209023: DIFFERENTIAL gears to move beyond their designed clearance.
• Premature bearing failure — Worn shims cause incorrect preload on the taper roller bearing, resulting in overheating and metallic debris in the transmission oil.
• Oil seepage at the differential housing — A collapsed shim alters the housing alignment, breaking the seal between the 5838300626: DIFFERENTIAL HOUSING and the transmission case.
• Vibration under load — Uneven shim wear creates axial play that translates into driveline shudder during acceleration or heavy digging operations.

Frequently Asked Questions

Q: Can I reuse the 0730.112.572 shim during a rebuild?
A: No. ZF recommends replacing this shim with a new OEM part every time the differential is disassembled. The shim compresses and work-hardens over time, so reusing it will not restore proper preload.

Q: How do I measure the correct shim thickness for my application?
A: Use a depth micrometer to measure the bearing bore depth in the differential housing, then subtract the bearing width. The resulting gap determines the required shim thickness. Always install the shim with the ground side facing the bearing race.

Q: Will this shim fit the ZF 4WG-180 transmission?
A: Yes. The 0730.112.572 shim is compatible with all WG180, WG200, and 4WG/6WG series transmissions that use the 5838300626 differential housing. Verify your housing part number to confirm fitment.
