ZF 0730.110.740 SHIM | OEM Genuine Part

Overview

This OEM genuine ZF 0730.110.740 SHIM is a precision-engineered spacer component designed to establish critical axial clearances within the differential and final drive assemblies of heavy-duty construction machinery transmissions. Positioned between the bearing race and the housing, this shim ensures correct preload on the 0750117075 TAPER ROLLER BEARING, preventing excessive end-play that leads to premature wear. The SKU 0730.110.740 is manufactured to exact OEM tolerances, guaranteeing a precise fit when installed alongside the 5838109012 DIFFERENTIAL assembly. Without this shim, the entire drivetrain geometry is compromised, resulting in accelerated component fatigue.

Symptoms of Failure

• Excessive differential backlash: When the 0730.110.740 shim compresses or wears, you will notice a clunking sound during direction changes, indicating lost preload on the 2093209023 DIFFERENTIAL gears.
• Oil seepage at the housing joint: A worn shim alters the clamping force on the 5838300626 DIFFERENTIAL HOUSING, creating gaps that allow transmission fluid to escape.
• Vibration under load: As the shim thickness degrades, the taper roller bearing loses its preload, causing driveline vibration that is most noticeable during low-speed maneuvering.
• Gear tooth pitting: Incorrect shim stack height forces the ring and pinion gears out of their ideal contact pattern, leading to rapid surface fatigue and eventual tooth breakage.

Technical Specifications

Compatibility

This shim is engineered for use in ZF WG180, WG200, and WG211 series powershift transmissions commonly found in wheel loaders, graders, and excavators. It specifically fits the differential carrier assembly where the 0750117075 TAPER ROLLER BEARING seats against the housing. The 0730.110.740 is also compatible with select ZF APL-300 and APL-400 series axles used in agricultural tractors. Always verify your transmission model number before ordering, as incorrect shim thickness will alter the preload on the 5838109012 DIFFERENTIAL assembly.

Frequently Asked Questions

Q: How do I know if the 0730.110.740 shim needs replacement?
A: Measure the differential bearing preload using a torque wrench. If the rotating torque of the differential falls below the OEM specification of 2.5-4.5 Nm, the shim has likely compressed and must be replaced.

Q: Can I stack multiple 0730.110.740 shims to adjust clearance?
A: No. This shim is designed as a single-use, single-layer spacer. Stacking shims will create an unstable assembly and cause the 0750117075 TAPER ROLLER BEARING to overheat. Use the correct thickness shim for your application.

Q: Is this shim compatible with the ZF WG180 transmission?
A: Yes, the 0730.110.740 is the factory-specified shim for the differential carrier in WG180, WG200, and WG211 transmissions. Always confirm your housing part number against the 5838300626 DIFFERENTIAL HOUSING to ensure fitment.
