Overview
The ZF 0735.358.199 ROLLER CAGE is a precision-engineered component designed for the WG 65 Series transmission. This OEM genuine part functions as a critical bearing retainer, positioning and guiding the needle rollers within the planetary gear set to ensure smooth torque transfer and reduced rotational friction. The SKU 0735.358.199 is installed directly inside the TRANSMISSION HOUSING, where it maintains correct gear alignment under heavy load conditions. By securing the roller elements in their proper raceway, this cage prevents metal-on-metal contact and extends the service life of the entire gear assembly.
Symptoms of Failure
When the ZF 0735.358.199 ROLLER CAGE wears out, operators typically notice these specific failure indicators:
- Gear slipping under load – A worn cage allows roller misalignment, causing intermittent power loss during acceleration or hill climbs.
- Metallic grinding noise from the transmission – Damaged roller cages produce a distinct rumbling or grinding sound, especially in neutral or low gear ranges.
- Increased operating temperature – Friction from displaced rollers generates excess heat, often triggering thermal warnings on the dashboard.
- Oil contamination with metallic debris – Flakes or fragments in the transmission fluid indicate cage material fatigue, requiring immediate inspection.

Compatibility
This ROLLER CAGE is specifically engineered for the ZF WG 65 Series transmission family. Based on its design and roller configuration, it is compatible with the following ZF models: WG65, WG80, WG120, WG180, and WG200. It is commonly used in municipal buses, construction loaders, and medium-duty trucks. For proper installation, this part must be paired with the correct HEXAGON SCREW (0636011038) and HEXAGON SCREW (0636011118) to secure the housing cover. Additionally, the HEXAGON SCREW (0636016015) is required for mounting the valve body assembly adjacent to the roller cage.
