ZF 4699.305.058 SHIM RING | OEM Genuine Part

Overview

The ZF 4699.305.058 SHIM RING is a precision-engineered OEM genuine component designed for critical axial clearance management within heavy-duty construction machinery transmissions. This shim ring, identified by SKU 4699.305.058, sits directly between the transmission housing and bearing assemblies to establish precise preload tolerances. By occupying this specific location, it prevents unwanted shaft movement and ensures that gear meshing remains within factory specifications. When paired with a 4699101086: HOUSING or a 4699301223: HOUSING, this shim ring becomes indispensable for maintaining the structural integrity of the gear train under extreme load conditions.

Symptoms of Failure

• Transmission oil seepage at housing joints — A worn 4699.305.058 shim ring allows housing faces to shift, breaking the seal and causing gradual fluid loss around the 0636302022: SCREW PLUG or 0501319149: SCREW PLUG locations.
• Intermittent gear slipping under load — When the shim ring loses its calibrated thickness, bearing preload drops, leading to momentary disengagement of drive gears during excavation or lifting cycles.
• Abnormal whining or grinding noise from the transmission case — Insufficient axial support causes gear faces to contact housing walls, producing a distinct metallic sound that worsens as the part degrades.
• Vibration during low-speed maneuvering — A collapsed or deformed shim ring permits lateral play in the main shaft, translating into perceptible chassis vibration when operating in first or reverse gear.

Technical Specifications

Compatibility

This shim ring is engineered for ZF WG-series powershift transmissions commonly deployed in wheel loaders, telehandlers, and excavators. Based on its dimensional profile and application in axial adjustment stacks, the 4699.305.058 is compatible with the following ZF transmission models: WG180, WG200, WG211, and WG310. It is also used in select ZF 4WG-200 and 6WG-310 variants where precise bearing preload is required. Always verify the existing shim stack thickness before replacement to maintain factory gear lash specifications.
