Overview
This OEM genuine ZF 0730.110.732 WASHER is a precision-engineered component designed to maintain critical axial clearances within the planetary gear sets of heavy-duty construction machinery transmissions. Positioned between rotating shafts and stationary housings, this hardened steel washer prevents metal-to-metal contact and ensures proper load distribution under extreme torque conditions. The SKU 0730.110.732 is an exact factory-spec replacement that matches original ZF tolerances for reliable long-term operation in demanding environments such as wheel loaders, graders, and dump trucks.
Symptoms of Failure
- Transmission oil leaks at the differential housing interface: A worn 0730.110.732 washer can cause misalignment, leading to seal failure and visible fluid seepage around the 5838300626: DIFFERENTIAL HOUSING.
- Gear slipping under load: Excessive axial play from a flattened washer reduces clutch pack clamping force, causing intermittent power loss during heavy lifting or climbing.
- Metallic grinding noises from the transmission sump: When the washer fractures, debris contaminates the oil system, accelerating wear on the 0750117075: TAPER ROLLER BEARING and adjacent planetary gears.
- Vibration during directional shifts: Worn clearance allows the 5838109012: DIFFERENTIAL assembly to shift axially, producing noticeable shuddering when engaging forward or reverse.

Compatibility
This washer is engineered for ZF WG series powershift transmissions commonly used in construction machinery. It directly fits the WG180, WG200, and WG250 models. It also appears in certain ZF 4WG-310 and 6WG-260 torque converter transmissions. Always verify clearance requirements when replacing the 2093209023: DIFFERENTIAL assembly, as shim stacks may need recalibration.

Frequently Asked Questions
Q: Can I reuse the 0730.110.732 washer during a rebuild?
A: No. This washer is a single-use component that deforms plastically during initial torque application. Always install a new OEM washer to maintain proper preload on the differential assembly.
Q: What tools are needed to replace this washer?
A: You will need a bearing puller for the 0750117075: TAPER ROLLER BEARING, a dial indicator to measure end-play, and a torque wrench calibrated to ZF specifications for the differential housing bolts.
Q: Does this washer fit the ZF 6WG-260 transmission?
A: Yes, the 0730.110.732 is used in the 6WG-260 planetary carrier assembly. However, always cross-reference your serial number because later production runs may use a thicker shim variant.
