Overview
The ZF 0730.008.813 WASHER is an OEM genuine shim designed specifically for the WG 200 series transmission. This precision-engineered component sits between the planetary gear set and the clutch housing, functioning as a critical thrust washer to maintain axial clearance and absorb operational loads. As part number 0730.008.813, it ensures proper gear alignment and prevents metal-on-metal contact within the rotating assembly. This washer is often replaced alongside the 4460165051 CONSOLE and the 4460368311 CONSOLE during a full overhaul, as both consoles support the washer’s seating surface.
Symptoms of Failure
- Transmission oil leaks near the bell housing: A worn 0730.008.813 washer can distort the seal surface, allowing ATF to seep past the output shaft area.
- Gear slipping under load: When the washer loses its precise thickness, axial play increases, causing clutch packs to engage inconsistently and slip during acceleration.
- Metallic grinding noise during shifting: Excessive wear on this washer leads to direct gear-to-housing contact, producing a distinct grinding sound in 2nd and 3rd gears.
- Delayed engagement from Neutral to Drive: A collapsed washer reduces hydraulic pressure in the forward clutch circuit, resulting in a noticeable lag when selecting Drive.

Compatibility
This washer is engineered for the ZF WG 200 series transmissions, including the WG180, WG200, and WG210 models. It is also found in select off-highway and marine variants of the WG family. For proper installation, always pair this washer with a new 0636011429 HEXAGON SCREW and the 0730100365 WASHER to ensure correct torque retention and load distribution. The WG200 series typically uses two of these washers per assembly—one on the input shaft and one on the output shaft.
