Overview
The ZF 0730.260.653 SPACER RING is a precision-engineered OEM genuine component designed specifically for the WG 200 Series transmission. This critical shim maintains exact axial clearance between rotating assemblies, ensuring proper load distribution and alignment within the gear train. The SKU 0730.260.653 is factory-machined to ZF’s strict tolerances, preventing metal-to-metal contact that can lead to premature wear. When installed alongside the 4460165051: CONSOLE and 4460368311: CONSOLE, this spacer ring creates the necessary preload for optimal gear engagement.
Symptoms of Failure
- Oil leaks near the transmission housing: A worn spacer ring allows axial movement, breaking the seal between the 0636011429: HEXAGON SCREW and housing, leading to fluid seepage.
- Gear slipping under load: When the spacer ring loses its thickness, gear stack preload drops, causing intermittent disengagement during torque transfer.
- Abnormal whining or grinding noises: Insufficient clearance from a collapsed spacer ring creates metal-on-metal contact, producing high-pitched sounds from the WG200 gearbox.
- Vibration during shifting: A deformed spacer ring allows shaft wobble, transmitting vibration through the 0730100365: WASHER and into the driveline.
