ZF 0730.062.240 SPACER RING for WG65 | OEM Genuine Part

Overview

The ZF 0730.062.240 SPACER RING is a precision-engineered component designed for the WG 65 Series of heavy-duty transmissions. This OEM genuine part functions as a critical axial spacer, ensuring correct clearance and alignment between rotating assemblies within the gear train. By maintaining precise positioning, the 0730.062.240 prevents metal-on-metal contact and supports proper load distribution across planetary gears. This spacer ring is installed directly against the TRANSMISSION HOUSING, where it acts as a wear-resistant buffer. The SKU 0730.062.240 is manufactured to ZF’s original tolerances, guaranteeing a perfect fit for your WG65 transmission overhaul.

Symptoms of Failure

• Transmission oil leaks at the housing joint: A worn spacer ring can cause misalignment, leading to gaps that allow ATF to seep past the O-RING seals.
• Gear slipping under load: When the spacer ring loses thickness, axial play increases, causing clutch packs to engage incompletely and resulting in power loss during acceleration.
• Metallic grinding noise from the bell housing: A collapsed spacer ring allows gear teeth to contact the housing, producing a distinct scraping sound during gear changes.
• Erratic shift timing: Worn spacers alter hydraulic pressure paths, leading to delayed or harsh shifts in the WG65 transmission.

Technical Specifications

Compatibility

This spacer ring is specifically engineered for the ZF WG 65 Series, including models such as WG65, WG120, WG180, and WG200. It is also compatible with certain ZF Ecomat 4HP and 5HP variants that share the same planetary carrier architecture. Always verify your transmission model before ordering. The 0730.062.240 is typically replaced during a full rebuild alongside the HEXAGON SCREW (M8x20) and HEXAGON SCREW (M10x25) that secure the housing assembly. For torque-critical applications, use the HEXAGON SCREW (M12x30) to ensure proper clamping force.
