Overview
The ZF 0735.301.584 ROLLER SET is a precision-engineered OEM genuine component designed for the planetary gear assemblies within heavy-duty ZF construction machinery transmissions. This roller set functions as a critical load-bearing element, reducing friction between rotating shafts and stationary housings while maintaining exact gear alignment under extreme torque conditions. The SKU 0735.301.584 is specifically calibrated to match the original factory tolerances for ZF powershift transmissions, ensuring consistent power delivery in wheel loaders, bulldozers, and excavators. When installed alongside the 4108101112: HOUSING and 4108201177: HOUSING, this roller set forms the core rotational support structure for the transmission’s intermediate shaft cluster.
Symptoms of Failure
- Transmission gear slipping under load: Worn rollers cause inconsistent gear engagement, particularly during heavy lifting or uphill operation, leading to sudden power loss.
- Metallic grinding noise from the transmission housing: Degraded roller surfaces produce a distinct scraping sound that intensifies with RPM, often misdiagnosed as bearing failure.
- Oil contamination with metallic particles: Flaking roller material mixes with transmission fluid, visible as silver or bronze debris on the dipstick or during oil changes.
- Vibration in the driveline during deceleration: Uneven roller wear creates harmonic oscillations felt through the chassis when the transmission downshifts.

Compatibility
This roller set is engineered for ZF WG180, WG200, and WG310 series powershift transmissions commonly used in construction machinery. It directly replaces the factory roller cage in the intermediate shaft planetary stage. The 0735.301.584 also fits select ZF 4WG-200 and 6WG-310 variants produced after 2005. For proper installation, always pair this roller set with a new 0636302056: SCREW PLUG to seal the housing access port, and verify the 4108301304: BEARING COVER is free of pitting before reassembly.
