ZF 2093.078.045 T 7226 | OEM Genuine Part

Overview

The ZF 2093.078.045 T 7226 is a precision-engineered OEM genuine component designed for the differential assembly within heavy-duty ZF transmissions. This part, identified by SKU 2093.078.045, functions as a critical internal gear or shaft element that manages torque distribution between the drive wheels in construction machinery. It sits directly within the differential housing, working in concert with the 2093109024 DIFFERENTIAL to ensure smooth power transfer under extreme loads. As an OEM genuine part, it guarantees exact fitment and metallurgical consistency for ZF transmissions operating in excavators, loaders, and graders.

Symptoms of Failure

• Intermittent gear slipping under load: When the 2093.078.045 wears, you may notice the transmission hesitates or loses drive torque during heavy excavation, often accompanied by a grinding noise from the differential area.
• Metallic debris in transmission oil: A common sign is finding fine metal shavings or larger fragments in the fluid during routine changes, indicating surface fatigue on the gear teeth or splines.
• Oil leaks near the differential housing: Worn seals or a compromised mating surface on this part can cause hydraulic fluid to weep from the housing, leading to low oil levels and eventual overheating.
• Vibration during straight-line travel: As the part degrades, uneven rotational forces create a persistent shudder felt through the chassis, especially when the machine is under partial throttle.

Technical Specifications

Compatibility

This OEM genuine part is engineered for ZF WG180, WG200, and WG250 series transmissions commonly used in construction machinery. It is also compatible with select ZF 4WG-180 and 4WG-200 variants found in wheel loaders and telehandlers. For precise fitment, always cross-reference your transmission serial number with the 2093.078.045 designation. The part integrates directly with the 2093209095 DIFFERENTIAL and the 2093309071 DIFF.HOUSING to form a complete differential assembly.

Frequently Asked Questions

Q: Can I install the 2093.078.045 without replacing the 0750117075 TAPER ROLLER BEARING?
A: It is strongly recommended to replace the taper roller bearing simultaneously, as worn bearings accelerate gear wear and can cause premature failure of the new part.

Q: What is the typical service life of this OEM genuine part in a wheel loader?
A: Under normal operating conditions with proper lubrication, the 2093.078.045 typically lasts 4,000 to 6,000 hours. Harsh environments or frequent heavy loads may reduce this interval.

Q: How do I verify this part fits my ZF WG200 transmission?
A: Check the transmission serial number plate and confirm the housing code matches the 2093.078.045 specification. The part is designed for WG200 series with a 28-spline differential input.
