Overview
The ZF 0730.006.267 SPACER RING is a precision-machined component engineered for the WG200, WG92, and WG98 series transmissions. This OEM genuine part functions as a critical axial spacer within the planetary gearset assembly, ensuring correct clearance between rotating elements and the TRANSMISSION HOUSING. By maintaining precise end-play tolerances, the spacer ring prevents metal-on-metal contact and supports proper oil flow through the clutch packs. The SKU 0730.006.267 is manufactured to ZF’s original specifications, guaranteeing exact fitment and long service life in heavy-duty industrial applications.
Symptoms of Failure
- Transmission oil leaks at the housing joint: A worn or deformed spacer ring can allow pressurized oil to bypass the O-RING seal, leading to external drips or puddles under the bell housing.
- Gear slipping under load: When the spacer ring loses its dimensional integrity, clutch pack clearance increases, causing intermittent slipping during torque converter lockup or range shifts.
- Abnormal whining or grinding noise: Insufficient axial support from the spacer ring allows planetary gears to contact the HOUSING, producing a distinct metallic whine that worsens with RPM.
- Delayed engagement from Neutral to Drive: Worn spacers reduce hydraulic pressure in the forward clutch circuit, resulting in a 2-3 second lag before the transmission engages.

Compatibility
This spacer ring is designed for ZF WG-series transmissions with modular planetary gearset architecture. Verified compatible models include WG180, WG200, WG90, WG92, WG94, and WG98. It also fits select WG150 variants when used with the RANGE SELECTOR assembly. For installations involving the PERIPHERALS kit, always verify axial stack-up using the latest ZF service bulletin. The part is not backward-compatible with pre-1990 WG80 series transmissions.
