ZF 2094.322.027 BUSH | OEM Genuine Part

Overview

This OEM genuine ZF 2094.322.027 BUSH is a precision-engineered wear component designed to provide a durable bearing surface within the planetary gear sets of heavy-duty construction machinery transmissions. Positioned between rotating shafts and stationary housings, this bushing absorbs radial loads and maintains critical alignment to ensure smooth power transfer. The SKU 2094.322.027 is manufactured to ZF’s exacting tolerances, making it a direct replacement part that restores factory-specified clearances and prevents premature wear on adjacent assemblies. When installed alongside a 5838109009: DIFFERENTIAL, this bushing supports the differential carrier’s rotational stability, reducing vibration and extending service life in demanding off-highway applications.

Symptoms of Failure

When the ZF 2094.322.027 bushing wears beyond its service limits, operators will notice distinct performance degradation. Look for these specific failure indicators:

• Transmission gear slipping under load — Worn bushings allow excessive shaft play, causing intermittent disengagement of clutch packs and planetary gears.
• Metallic grinding noise from the differential area — As the bushing wall thins, metal-to-metal contact occurs between the shaft and housing, producing a distinct scraping sound during acceleration or deceleration.
• Oil seepage around the transmission housing seals — Increased radial clearance from a degraded bushing distorts seal alignment, leading to gradual hydraulic fluid leaks that contaminate the undercarriage.
• Abnormal heat buildup in the transmission sump — Friction from a failing bushing generates excess thermal energy, often triggering over-temperature warnings on the machine’s dashboard.

Compatibility

This bushing is engineered for ZF’s WG series powershift transmissions commonly used in wheel loaders, graders, and material handlers. It is a direct fit for the following transmission models:

• ZF WG180
• ZF WG200
• ZF WG211
• ZF WG310

In these transmissions, the bushing works in concert with a 0750117075: TAPER ROLLER BEARING to manage axial and radial forces within the differential housing. For complete assembly restoration, pair this bushing with a 2093209023: DIFFERENTIAL and a 5838300626: DIFFERENTIAL HOUSING to ensure all mating surfaces meet OEM clearance specifications.

Frequently Asked Questions

Q: How do I know if the 2094.322.027 bushing is the correct replacement for my transmission?
Verify your transmission model against the WG180, WG200, WG211, or WG310 series listed above. Additionally, measure the inner diameter of the existing bushing; if it exceeds 45.10 mm, replacement is necessary to avoid damage to the shaft and differential housing.

Q: Can I reuse the old bushing if it shows only minor wear?
No. ZF bushings are designed as single-use wear items. Even minor ovality or scoring will accelerate wear on the 0750117075: TAPER ROLLER BEARING and the differential assembly. Always replace the bushing during any transmission overhaul to maintain factory tolerances.

Q: What torque specifications apply when installing this bushing?
This bushing is press-fit into the housing; no torque is applied directly to it. However, when reinstalling the differential housing, tighten the housing bolts to 120 Nm (88 lb-ft) for WG180 and WG200 models, and 150 Nm (110 lb-ft) for WG211 and WG310 models.
