Overview
This ZF 0730.110.744 WASHER is an OEM genuine component engineered to maintain precise axial clearance and load distribution within heavy-duty construction machinery transmissions. Positioned between rotating assemblies and housing surfaces, this hardened steel washer prevents metal-on-metal contact that can lead to premature gear wear. The SKU 0730.110.744 is specifically designed to withstand high torque loads in ZF power shift transmissions, ensuring consistent oil film thickness between mating parts. When installed alongside a 2094104412: MAIN SHAFT, this washer stabilizes shaft end-play and reduces vibration transfer through the drivetrain.
Symptoms of Failure
- Transmission oil seepage around shaft seals – A worn 0730.110.744 washer allows excessive axial movement, distorting seal lips and causing fluid migration past the output flange.
- Intermittent gear slipping under load – When this washer loses its original thickness, the 2094304054: MAIN SHAFT can shift out of alignment, reducing gear engagement depth during excavation cycles.
- Metallic grinding noise during clutch engagement – Degraded washer material permits contact between the 2094106010: SHIFT SYSTEM components and housing, creating audible friction sounds in low-range gears.
- Increased backlash in the driveline – A collapsed washer creates measurable free play between the 2094206001: GEARSHIFT SHAFT and its bore, causing delayed power delivery when reversing direction.

Frequently Asked Questions
Q: Can I reuse the 0730.110.744 washer during a transmission rebuild?
A: No. This washer is a single-use component because it compresses slightly during initial torque application. Reusing it can cause incorrect end-play and accelerate bearing failure.
Q: How do I know if my ZF transmission needs this specific washer?
A: Measure the axial clearance between the main shaft and housing using a dial indicator. If clearance exceeds 0.15 mm, the 0730.110.744 washer likely requires replacement. Always compare with the 2094306019: WASHER for thickness differences.
Q: Does this washer fit both WG180 and WG200 transmissions?
A: Yes, the 0730.110.744 is a shared part across these series. However, verify that the 0630513070: SNAP RING groove depth matches your housing to avoid installation issues.
