ZF 0730.010.747 SHIM | OEM Genuine Part

Overview

The ZF 0730.010.747 SHIM is a precision-engineered OEM genuine part designed to establish the correct axial clearance and preload within ZF heavy-duty transmissions. This thin, hardened steel component sits between the differential housing and the bearing race, compensating for manufacturing tolerances to ensure optimal gear mesh and load distribution. The SKU 0730.010.747 is critical for maintaining the structural integrity of the differential assembly, directly influencing torque transfer efficiency in construction machinery. When installed alongside a 5838109012: DIFFERENTIAL, this shim prevents lateral movement that would otherwise cause premature wear on adjacent components.

Symptoms of Failure

• Excessive differential backlash — A worn or collapsed shim allows the differential to shift axially, producing a distinct clunking noise during acceleration or deceleration. This is a common “differential shim failure symptoms” search query.
• Oil seepage at the housing joint — When the shim loses its calibrated thickness, the housing seal gap widens, leading to “ZF transmission oil leak between housing” issues.
• Gear tooth pitting or chipping — Incorrect preload from a degraded shim causes uneven contact patterns on the bevel gears, resulting in “construction machinery gear wear” that accelerates failure of the 2093209023: DIFFERENTIAL.
• Vibration at the drive axle — Operators may feel a low-frequency shudder through the chassis, indicating the shim can no longer stabilize the 0750117075: TAPER ROLLER BEARING against axial forces.

Technical Specifications

Compatibility

This shim is specifically engineered for ZF’s WG series powershift transmissions commonly found in wheel loaders, graders, and telehandlers. It is a direct fit for the ZF WG180, WG200, and WG211 models. The 0730.010.747 is also used in the differential section of the ZF 4WG-200 and 5WG-210 transmissions. For proper assembly, always pair this shim with a new 5838300626: DIFFERENTIAL HOUSING to ensure the seating surface is free of burrs.

Frequently Asked Questions

Q: Can I reuse the 0730.010.747 shim during a rebuild?
A: No. ZF specifies that this shim must be replaced whenever the differential is disassembled. The shim compresses plastically during initial torqueing and will not provide accurate preload if reused.

Q: How do I measure the correct shim thickness for my ZF WG200?
A: Use a depth micrometer to measure the bearing bore depth in the differential housing, then subtract the bearing height. The difference indicates the required shim thickness. The 0730.010.747 is a 0.75mm baseline; you may need to stack it with other shims.

Q: Will this shim fit a ZF 4WG-310 transmission?
A: No. The 4WG-310 uses a larger differential housing (part 5838300626) and requires a shim with a 92mm outer diameter. Always verify your transmission model before ordering.
