Overview
The ZF 0634.307.367 SCRAPER is a precision-engineered sealing component designed to prevent contaminants from entering the transmission housing while retaining critical lubricants. Positioned at the output shaft interface of heavy-duty construction machinery transmissions, this OEM genuine part ensures a tight seal against abrasive debris, moisture, and dust. The SKU 0634.307.367 is specifically calibrated for high-torque applications, working in concert with the 5838109012: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING to maintain drivetrain integrity. Without this scraper, the internal components—including the 2093209023: DIFFERENTIAL—face accelerated wear from particle ingress.
Symptoms of Failure
- Transmission oil seepage at output shaft: A worn scraper allows thin oil films to escape, often visible as wet spots around the flange. This is a common “ZF transmission oil leak at output shaft” issue.
- Gravel or dirt buildup near seal area: When the scraper loses its wiping edge, abrasive particles accumulate, leading to “construction machinery transmission contamination” and scoring on the shaft.
- Whining or grinding noise during operation: Loss of seal integrity permits debris to reach the 5838300626: DIFFERENTIAL HOUSING, causing metallic wear sounds under load.
- Premature bearing failure: Contaminated lubricant accelerates taper roller bearing degradation, often misdiagnosed as a “ZF gearbox bearing noise” problem.

Compatibility
This scraper is engineered for ZF WG-series powershift transmissions commonly used in wheel loaders, graders, and dump trucks. Compatible models include WG180, WG200, WG210, and WG240 series. It also fits select ZF 4WG-200 and 6WG-200 variants. Always verify the output shaft diameter matches the 65 mm inner dimension before installation. For differential assembly work, pair this scraper with the 5838109012: DIFFERENTIAL and 0750117075: TAPER ROLLER BEARING for optimal sealing and load support.

Frequently Asked Questions
Q: Can I reuse the old scraper if it looks intact?
No. The elastomer hardens over time, losing its wiping ability. Always replace with the ZF 0634.307.367 scraper during any differential or bearing service.
Q: Does this scraper fit ZF 4WG-200 transmissions?
Yes, it is compatible with 4WG-200 and 6WG-200 models, provided the output shaft diameter is 65 mm. Verify by measuring the shaft before ordering.
Q: What torque should I apply to the retaining bolts?
Use 25 Nm for the scraper housing bolts. Over-tightening can distort the scraper lip and cause premature failure.
