Overview
The ZF 0730.006.265 SPACER RING is a precision-machined OEM genuine component engineered for the WG200, WG92, and WG98 transmission series. This critical shim sits between the TRANSMISSION HOUSING and the planetary gear set, ensuring correct axial clearance and load distribution. As an original ZF part, the 0730.006.265 maintains factory tolerances for optimal gear mesh and torque transfer. When paired with a PERIPHERALS kit, this spacer ring prevents metal-to-metal contact that can lead to premature wear in heavy-duty industrial applications.
Symptoms of Failure
- Oil leaks around the transmission housing joint – A worn spacer ring allows the HOUSING to shift, breaking the seal and causing fluid seepage.
- Gear slipping under load – Excessive axial play from a degraded spacer ring reduces clutch pack engagement, leading to intermittent power loss.
- Metallic grinding noise during shifting – When the spacer ring collapses, planetary gears contact the RANGE SELECTOR assembly, producing audible wear.
- Vibration in neutral or drive – Uneven spacer ring thickness creates imbalance that resonates through the driveline at specific RPMs.
