ZF 4699.300.152 TOOTHED DISC | OEM Genuine Part

Overview

The ZF 4699.300.152 TOOTHED DISC is a critical friction component engineered for high-torque applications within ZF powershift transmissions. This OEM genuine part, identified by SKU 4699.300.152, functions as a load-bearing interface inside the clutch pack assembly, transferring rotational force from the hub to the outer drum. Precision-machined splines on the inner diameter engage directly with the 4699100023: BASIC PARTS hub, while the outer teeth lock into the 4699300138: HOUSING to ensure positive engagement under extreme loads. Without this disc, the transmission cannot modulate gear engagement or maintain torque flow.

Symptoms of Failure

• Erratic gear engagement or delayed shifting – Worn teeth cause the disc to skip or fail to lock into the housing, leading to hesitation when selecting forward or reverse gears.
• Metallic grinding noise during clutch actuation – Broken or chipped splines produce a distinct scraping sound as the disc contacts the 4699300156: GEAR SHAFT under load.
• Transmission fluid contamination with bronze or steel particles – Friction material degradation sheds debris into the oil circuit, often visible during routine filter inspections.
• Partial power loss under heavy load – A slipping toothed disc prevents full torque transfer, causing the machine to lose pulling power on inclines or during digging operations.

Technical Specifications

Compatibility

This toothed disc is designed for use in ZF WG series transmissions commonly found in construction machinery. Based on its dimensional profile, the 4699.300.152 is compatible with the following models: WG180, WG200, and WG211. It also fits select variants of the ZF 4WG-200 and ZF 5WG-210 series. Always verify the disc’s spline count against your existing 4699300127: PLANET CARRIER assembly before installation.
