ZF 0730.008.795 SHIM | OEM Genuine Part

Overview

The ZF 0730.008.795 SHIM is a precision-engineered OEM genuine component designed to establish critical axial clearance within heavy-duty ZF powershift transmissions. This thin, hardened steel shim sits between the transmission housing and the bearing support structures, ensuring correct preload and alignment of rotating assemblies. The SKU 0730.008.795 is specifically utilized in construction machinery transmissions to prevent gear train misalignment and to maintain optimal oil film thickness between moving parts. By compensating for manufacturing tolerances, this shim directly influences the longevity of adjacent components such as the 2094101012: TRANSMISSION HOUSING and the 2094301036: HOUSING.

Symptoms of Failure

• Excessive axial play in the transmission shaft: When the shim wears or compresses beyond tolerance, you will detect noticeable end-float in the main shaft, leading to “ZF transmission gear slipping under load” and erratic shifting behavior.
• Low-frequency bearing rumble: A worn shim allows bearing raceways to shift, producing a deep, rhythmic noise that intensifies with engine RPM—often described as “construction machinery transmission bearing noise.”
• Oil contamination from metal debris: As the shim surface degrades, microscopic steel particles enter the lubrication circuit, causing “transmission oil contamination symptoms” and accelerated wear on seals like the 0750111371: SHAFT SEAL.
• Intermittent loss of drive in forward gears: Misalignment caused by a collapsed shim can cause the clutch packs to partially disengage, resulting in “ZF transmission losing forward gears” during heavy excavation work.

Technical Specifications

Compatibility

This shim is engineered for ZF WG-series powershift transmissions commonly installed in wheel loaders, graders, and dump trucks. It is a direct fit for the ZF WG180, WG200, and WG210 transmission models. The 0730.008.795 shim is also used in certain variants of the ZF 4WG-200 and ZF 6WG-250 series, where it sits between the 2094298057: HOUSING and the 2094301071: COVER assembly. Always verify your transmission model tag before ordering, as shim stacks may vary by application.

“@type”: “Answer”,
“text”: “The 0730.008.795 shim adjusts axial clearance between the transmission housing and bearing assemblies. It ensures proper preload on the shaft bearings, preventing gear misalignment and reducing vibration in ZF WG180, WG200, and WG210 transmissions.”

“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “Key indicators include excessive shaft end-play, a low-frequency bearing rumble during operation, metal particles in the transmission oil, and intermittent loss of forward drive. Measuring axial clearance with a dial indicator confirms if the shim has worn beyond the 0.50 mm specification.”

“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “ZF recommends replacing all shims during a rebuild. The hardened steel can take a permanent set over time, and reusing it may lead to incorrect bearing preload. Always install a new OEM 0730.008.795 shim and verify clearance with the service manual.”
