ZF 0635.470.190 ROLLER for WG92/WG98 | OEM Genuine Part

Overview

The ZF 0635.470.190 ROLLER is a precision-engineered component designed for the planetary gearset assembly within the WG92 and WG98 series transmissions. This OEM genuine part functions as a critical load-bearing element, reducing friction between rotating shafts and stationary housings during torque transfer. The SKU 0635.470.190 is specifically machined to maintain exacting clearances within the gear train, ensuring smooth power delivery in heavy-duty industrial applications. When installed alongside the TRANSMISSION HOUSING, this roller supports the axial and radial forces generated during high-torque operations, directly influencing the transmission’s overall efficiency and service life.

Symptoms of Failure

• Intermittent gear slipping under load: Worn rollers cause uneven pressure on planetary gears, leading to momentary loss of torque transfer during acceleration or climbing.
• Metallic grinding noise from transmission housing: Degraded roller surfaces create audible friction against the HOUSING II, particularly noticeable in neutral or low-gear operation.
• Increased operating temperature: Failed rollers generate excessive heat due to metal-on-metal contact, often triggering thermal warning systems in WG92/WG98 units.
• Oil contamination with metallic particles: Worn roller fragments circulate through the hydraulic system, accelerating wear on seals and valves.

Technical Specifications

Compatibility

This roller is engineered for ZF WG series transmissions, specifically the WG92 and WG98 models. It is also compatible with WG180, WG200, and WG210 variants that share the same planetary carrier design. The part interfaces directly with the CYLINDRICAL PIN that secures the roller within the gearset, and its proper installation is verified via the TYPE PLATE specifications. Always cross-reference your transmission’s serial number with the OEM parts catalog before ordering.
