ZF 0730.108.465 SHIM | OEM Genuine Part

Overview

The ZF 0730.108.465 SHIM is a precision-engineered OEM genuine component designed to establish critical axial clearances within heavy-duty ZF transmissions used in construction machinery. This thin, hardened steel shim sits between the differential housing and the bearing race, allowing technicians to fine-tune gear mesh and preload during assembly or rebuild. The SKU 0730.108.465 is a factory-specified part that ensures the differential assembly maintains proper alignment under extreme loads. When installed alongside a 5838109012: DIFFERENTIAL, this shim prevents lateral movement that would otherwise accelerate wear on adjacent components.

Symptoms of Failure

• Excessive differential backlash causing driveline clunking: When the 0730.108.465 shim compresses or corrodes, clearance increases between the differential and its housing, producing a metallic knock during acceleration or deceleration.
• Premature taper roller bearing failure from improper preload: A worn shim alters the crush load on the 0750117075: TAPER ROLLER BEARING, leading to overheating and spalling of the bearing rollers.
• Oil leaks at the differential housing seal interface: As the shim thickness decreases, the housing shifts, breaking the seal contact pattern and allowing transmission fluid to weep past the gasket.
• Intermittent gear slipping under load in construction equipment: Loss of shim integrity allows the 2093209023: DIFFERENTIAL to walk axially, causing momentary disengagement of the pinion from the ring gear.

Technical Specifications

Compatibility

This shim is a factory-fit component for ZF heavy-duty powershift transmissions commonly found in wheel loaders, dozers, and graders. It is specifically used in the WG180, WG200, and WG310 series transmissions. The 0730.108.465 shim also appears in certain ZF 4WG-200 and 6WG-200 variants where the 5838300626: DIFFERENTIAL HOUSING requires precise shimming to accommodate the differential assembly. Always verify your transmission model tag before ordering.

Frequently Asked Questions

Q: Can I reuse the 0730.108.465 shim during a transmission rebuild?
A: No. ZF specifies that this shim must be replaced with a new OEM part during any differential or bearing service. The shim work-hardens and loses its original thickness, making accurate preload impossible to achieve with a used part.

Q: How do I know if I need a 0.50 mm shim or a different thickness?
A: The required shim thickness is determined by measuring the clearance between the differential housing and the bearing outer race using a depth micrometer. The 0730.108.465 is the standard service shim; if your clearance differs, you may need a thicker or thinner shim from the ZF 0730 series.

Q: Will this shim fit a ZF 4WG-310 transmission?
A: Yes, the 0730.108.465 is compatible with the 4WG-310 series, provided the differential housing part number matches the 5838300626 specification. Always cross-reference your housing casting number before installation.
