ZF 4699.300.105 SHIM RING | OEM Genuine Part

Overview

The ZF 4699.300.105 SHIM RING (SKU: 4699.300.105) is a precision-engineered OEM genuine component designed for critical axial clearance adjustment within ZF construction machinery transmissions. This shim ring sits between the 4699101002: HOUSING and the 4699301188: HOUSING assembly, ensuring correct preload on bearing sets and planetary gear stacks. By maintaining exacting tolerances, the 4699.300.105 prevents internal component contact and ensures smooth torque transfer under heavy loads. As an OEM genuine part, it guarantees material consistency and dimensional accuracy that aftermarket alternatives cannot match.

Symptoms of Failure

• Transmission gear slipping under load: When the shim ring wears or compresses beyond specification, axial play increases, causing gears to lose proper engagement during high-torque operations.
• Abnormal bearing noise or vibration: A worn 4699.300.105 allows bearing races to shift, producing a distinct rumbling or whining sound from the transmission housing.
• Oil leaks at housing mating surfaces: Excessive clearance forces the 0636015047: HEXAGON SCREW fasteners to bear uneven stress, distorting the housing seal and causing fluid seepage.
• Premature clutch pack failure: Incorrect shim thickness alters hydraulic pressure distribution, leading to clutch slippage and burnt friction plates.

Technical Specifications

Compatibility

This shim ring is engineered for ZF WG series transmissions commonly found in wheel loaders, graders, and heavy dump trucks. It is directly compatible with ZF WG180, WG200, and WG211 models. The part also fits select ZF 4WG-200 and ZF 6WG-250 power shift transmissions. Always verify your transmission serial number before ordering, as shim thickness requirements vary by assembly stack-up. The 4699.300.105 is installed in conjunction with the 4699301128: COVER to complete the bearing preload circuit.
