ZF 0501.314.795 CAM DISC | OEM Genuine Part

Overview

The ZF 0501.314.795 CAM DISC is a precision-machined component engineered to control the sequential engagement of clutch packs within heavy-duty ZF powershift transmissions. Positioned inside the valve body or hydraulic control unit, this disc translates rotational motion into linear actuation, directing oil flow to specific clutches. As an OEM genuine part, the SKU 0501.314.795 ensures exact fitment and durability for demanding construction machinery applications. When paired with a properly sealed HOUSING, the cam disc maintains consistent hydraulic timing, preventing premature wear across the entire transmission assembly.

Symptoms of Failure

• Erratic gear engagement or delayed shifting: A worn cam disc loses its precise lobe profile, causing clutch packs to engage at incorrect intervals. Operators often report “clutch slipping under load” or “transmission hesitation when shifting from forward to reverse.”
• Metallic rattling from the transmission housing: As the cam disc surface degrades, it produces a distinct clicking or grinding noise during gear changes. This symptom is frequently searched as “ZF transmission rattling noise when shifting.”
• Intermittent loss of drive in specific gears: When the cam disc fails to rotate fully, hydraulic pressure drops in one or more clutch circuits. This manifests as “transmission drops out of gear under heavy load” on construction sites.
• Contaminated hydraulic fluid with metallic particles: Flaking material from the cam disc circulates through the system, accelerating wear on the MOTOR and other precision components. Oil analysis often reveals elevated iron content.

Technical Specifications

Compatibility

This cam disc is primarily used in ZF WG180, WG200, and WG210 series powershift transmissions found in wheel loaders, graders, and telehandlers. It also fits select ZF 4WG-200 and 6WG-200 models. For proper installation, ensure the mating COVER is free of burrs and the TAPERED ROLLER BEARING is replaced simultaneously to maintain axial clearance. Always verify transmission serial number against ZF parts catalog before ordering.
