Overview
The ZF 4699.801.092 GK10 is an OEM genuine gearset component engineered for heavy-duty construction machinery transmissions. This precision-machined part sits within the planetary gear assembly of ZF’s powershift transmissions, directly transferring torque from the input shaft to the output shaft under high-load conditions. The SKU 4699.801.092 is specifically designed to maintain gear mesh alignment and reduce vibration in demanding off-highway applications. When paired with the 4699001092: GK10 assembly, this component ensures seamless power delivery during digging, grading, or hauling operations. Its hardened steel construction resists pitting and wear, making it a critical element for long service intervals in wheel loaders and dump trucks.
Symptoms of Failure
- Intermittent gear slipping under load – A worn 4699.801.092 can cause the transmission to momentarily lose torque when climbing grades or pushing heavy material, often accompanied by a grinding noise.
- Metallic debris in transmission fluid – As the gearset teeth degrade, fine steel particles contaminate the oil, leading to accelerated wear of the 4699101094: HOUSING and other internal components.
- Oil seepage near the output flange – Excessive play in the gearset can distort the 0501329881: HOUSING COVER, causing hydraulic fluid to leak past the seal.
- Delayed engagement when shifting – Worn teeth reduce hydraulic pressure response, making the transmission hesitate before engaging forward or reverse gears.

Compatibility
This genuine ZF part is primarily used in the WG180, WG200, and WG210 series powershift transmissions found in construction machinery. It also fits select models of the 4WG-200 and 5WG-180 transfer cases. For proper installation, ensure the 4699103063: OUTPUT shaft is free of scoring and that the snap ring (part 0630513065: SNAP RING) is replaced simultaneously. Always verify the O-ring (0634306309: O-RING) and breather (0637885612: BREATHER) are in good condition to prevent contamination.
