ZF 0730.109.376 SHIM | OEM Genuine Part

Overview

The ZF 0730.109.376 SHIM is a precision-engineered OEM genuine component designed to establish exact axial clearances within heavy-duty ZF transmissions. This thin, hardened steel spacer sits between gear assemblies and bearing races, compensating for manufacturing tolerances and preventing unwanted lateral movement. Proper shimming is critical for maintaining correct gear mesh patterns and bearing preload. The SKU 0730.109.376 is a factory-specified part for construction machinery drivelines, ensuring that load distribution across the differential assembly remains within factory tolerances. When installed alongside a 5838109012: DIFFERENTIAL, this shim guarantees that the ring gear and pinion maintain their optimal contact pattern under high torque loads.

Symptoms of Failure

When the ZF 0730.109.376 SHIM wears or collapses, three distinct failure modes emerge. First, excessive driveline backlash becomes noticeable during directional changes, causing a clunking sound when shifting from forward to reverse. Second, premature bearing noise develops as the 0750117075: TAPER ROLLER BEARING loses its correct preload, producing a whining or growling sound that intensifies with vehicle speed. Third, uneven tire wear patterns appear on construction equipment, indicating that the differential carrier has shifted out of alignment. Fourth, metal particles in the transmission oil signal that the shim has been ground down, allowing gear teeth to contact improperly. These symptoms often prompt operators to inspect the entire 2093209023: DIFFERENTIAL assembly for collateral damage.

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 WG180 and WG200 series, as well as the WG211 and WG220 models used in wheel loaders, graders, and dump trucks. The shim also appears in the 4WG-200 and 6WG-200 transmission variants. When rebuilding these units, technicians should always pair this shim with a new 5838300626: DIFFERENTIAL HOUSING to ensure the bearing bores are perfectly aligned. The 0730.109.376 is also used in the differential carrier assembly of certain ERGO series transmissions for mobile cranes.

Frequently Asked Questions

Q: Can I reuse the ZF 0730.109.376 shim during a rebuild?
A: No. This shim is a single-use component. Once compressed during initial assembly, it loses its precise thickness. Always install a new 0730.109.376 shim and measure backlash with a dial indicator.

Q: How do I verify the correct shim thickness for my transmission?
A: Use a depth micrometer to measure the bearing bore depth in the 5838300626: DIFFERENTIAL HOUSING. Subtract the bearing width and target preload to determine if the 0.50 mm shim is appropriate. ZF offers shims in 0.10 mm increments for fine-tuning.

Q: Will a worn shim damage the taper roller bearing?
A: Absolutely. A collapsed shim allows the 0750117075: TAPER ROLLER BEARING to operate with zero preload, causing the rollers to skid rather than roll. This leads to rapid spalling and bearing cage failure within 50 operating hours.
