Overview
This OEM genuine ZF 2093.009.029 T 7226 L is a precision-engineered internal component designed for heavy-duty construction machinery transmissions. It functions as a critical load-bearing and torque-transfer element within the planetary gear set of ZF’s advanced powershift systems. The part number 2093.009.029 identifies a specific hardened steel gear or shaft assembly that ensures smooth power delivery from the engine to the final drive. When installed alongside a 5838109009: DIFFERENTIAL, this component helps maintain precise gear alignment and reduces internal stress on the drivetrain.
Symptoms of Failure
- Intermittent gear slipping under load – Worn teeth on the 2093.009.029 can cause the transmission to momentarily lose torque when climbing grades or carrying heavy payloads.
- Metallic grinding noise from the transmission housing – As the part degrades, loose metal fragments may produce a distinct scraping sound during gear changes, especially in cold-start conditions.
- Oil contamination with fine metallic particles – A failing unit often sheds debris into the hydraulic circuit, which can be detected during routine fluid analysis and may clog the filter prematurely.
- Delayed engagement when shifting from neutral to drive – Excessive play in this component can cause a noticeable lag before power is transmitted to the wheels.

Frequently Asked Questions
Q: How do I confirm that the 2093.009.029 is the correct replacement for my ZF transmission?
Check the stamped identification tag on your transmission housing. If the model number begins with WG180 or WG200, this part is a direct fit. Always verify the spline count and tooth profile against your existing component before installation.
Q: Can I reuse the old thrust washers when installing this new part?
No. ZF recommends replacing all 5838300811: THRUST WASHER and 5838300753: THRUST WASHER components simultaneously to prevent uneven wear and premature failure of the new gear set.
Q: What is the typical service life of this OEM part in a wheel loader application?
Under normal operating conditions with proper lubrication and regular filter changes, the 2093.009.029 can last 6,000 to 8,000 hours. Harsh environments with heavy dust or shock loads may reduce this interval by up to 30%.
