ZF 0750.115.237 ROLLER CAGE for WG150 | OEM Genuine Part

Overview

The ZF 0750.115.237 ROLLER CAGE is a precision-engineered component designed for the WG150 series transmission. This OEM genuine part functions as a critical bearing retainer, ensuring that needle rollers remain evenly spaced and securely positioned within the planetary gear set. By maintaining correct roller alignment, this cage reduces friction and distributes load evenly across the gear train. The SKU 0750.115.237 is factory-specified for direct replacement, guaranteeing exact fitment and original performance standards. It sits directly within the planetary carrier assembly, interfacing with the TRANSMISSION HOUSING (4642101108) and the TRANSMISSION HOUSING (4642301208) to form a sealed, high-torque environment.

Symptoms of Failure

When the roller cage wears out, operators may notice distinct operational issues. “Transmission whining noise during acceleration” often indicates that the cage has lost its structural integrity, allowing rollers to shift out of alignment. Another common symptom is “intermittent gear slipping under load”, which occurs when the cage no longer holds rollers in their correct positions, leading to momentary torque loss. “Metallic debris in transmission fluid” is a telltale sign of cage fragmentation, as broken cage segments contaminate the oil. Finally, “hard shifting between forward gears” can result from increased friction and binding within the roller assembly, placing additional strain on the TYPE PLATE (0730365125) and surrounding components.

Technical Specifications

Compatibility

This roller cage is specifically engineered for the ZF WG150 transmission series. It also fits select variants of the WG180 and WG200 models where the planetary gear set shares identical roller spacing. For precise cross-referencing, always verify the transmission serial number against the OEM parts catalog. The cage works in conjunction with the GROOVED STUD (0631311009), which secures the assembly to the carrier. Additional compatible models include the WG120 and WG250 when equipped with the same planetary stage.
