Overview
This genuine ZF 0730.108.547 WASHER is a precision-engineered component designed to maintain critical axial clearances within the transmission assembly. Positioned between rotating shafts and stationary housings, this OEM washer prevents metal-on-metal contact and ensures proper load distribution during high-torque operations. The SKU 0730.108.547 is commonly found in heavy-duty construction machinery transmissions, where it supports the main shaft assembly and helps maintain oil pressure integrity. Without this washer, gear alignment can shift, leading to premature wear on adjacent components.
Symptoms of Failure
- Transmission oil leaks near the shaft housing – When the 0730.108.547 washer wears thin, sealing surfaces lose contact, allowing hydraulic fluid to escape. This is a common search query for “ZF washer oil leak repair.”
- Gear slipping under load – A degraded washer increases axial play, causing the 2094104412: MAIN SHAFT to shift position during operation. Operators often search for “transmission slipping when accelerating.”
- Metallic grinding noises from the transmission – Insufficient washer thickness allows the 2094304054: MAIN SHAFT to contact the housing, producing a distinct grinding sound. This symptom is frequently queried as “ZF transmission grinding noise fix.”
- Difficulty engaging gears – Worn washers disrupt the 2094106010: SHIFT SYSTEM alignment, making gear changes stiff or impossible. Technicians often look for “hard shifting ZF transmission solutions.”

Frequently Asked Questions
Q: How do I know if my ZF 0730.108.547 washer is worn out?
A: Measure the washer thickness with a micrometer. If it measures less than 2.3 mm, replacement is recommended. Also check for uneven wear patterns or burrs on the surface.
Q: Can I reuse this washer during a transmission rebuild?
A: No. ZF specifies that the 0730.108.547 washer must be replaced with a new OEM part during any major transmission service. Reusing it risks oil leaks and gear misalignment.
Q: Does this washer work with the WG180 transmission?
A: Yes, the 0730.108.547 is a standard fitment for WG180, WG200, and WG210 models. Always cross-reference your transmission serial number with the parts catalog for confirmation.
