ZF 0732.612.008 BREATHER for WG65 | OEM Genuine Part

Overview

The ZF 0732.612.008 BREATHER is a critical ventilation component engineered for the WG65 series of heavy-duty transmissions. This OEM genuine part equalizes internal pressure within the transmission housing, preventing contaminant ingress while allowing hot air and vapor to escape. Installed on the upper casing, the breather maintains a clean operating environment for internal gears and clutches. The SKU 0732.612.008 is a direct replacement designed to restore factory-spec performance in ZF WG65 gearboxes.

Symptoms of Failure

• Oil leaks around the transmission housing: A clogged or failed breather causes pressure buildup, forcing lubricant past seals and gaskets. If you notice oil weeping near the top of the TRANSMISSION HOUSING, inspect the 0732.612.008 breather immediately.
• Milky or contaminated transmission fluid: When the breather cannot vent properly, moisture and debris are drawn into the gearbox. This leads to emulsified oil and accelerated wear on internal components.
• Whining or overheating transmission: Restricted airflow from a blocked breather raises internal temperatures, causing gear noise and potential slipping under load.
• Visible dirt or sludge near the breather cap: A failed valve allows road grime to enter the assembly, often accompanied by a sticky residue around the vent port.

Technical Specifications

Compatibility

This breather is specifically validated for the ZF WG65 series, including models WG65, WG80, WG120, WG150, WG180, and WG200. It also fits select off-highway transmissions in the Ecomat 4HP and 5HP families. Always verify thread compatibility with your TRANSMISSION HOUSING before installation. For secure mounting, use a HEXAGON SCREW (M8) and HEXAGON SCREW (M10) for adjacent brackets, plus a HEXAGON SCREW (M12) for the main cover plate.
