ZF 4699.397.005 FRAME PLATE | OEM Genuine Part

Overview

The ZF 4699.397.005 FRAME PLATE is a critical structural component within the final drive assembly of heavy-duty construction machinery transmissions. This OEM genuine part serves as the rigid mounting interface that secures the planetary gear set and differential housing to the axle housing. As a precision-machined plate, it absorbs significant torsional loads and maintains proper gear alignment under extreme operating conditions. The SKU 4699.397.005 is engineered to ZF’s original specifications, ensuring exact bolt-hole patterns and surface flatness for leak-free sealing when paired with the 4699101045 HOUSING and 4699301108 HOUSING.

Symptoms of Failure

• Oil seepage at the axle-to-transmission interface: A warped or cracked frame plate compromises the sealing surface, causing gradual hydraulic fluid loss that stains the undercarriage.
• Abnormal gear whine or grinding during load cycles: When the plate loses its dimensional integrity, planetary gear alignment shifts, producing a distinct metallic noise under torque.
• Vibration in the driveline during acceleration: A fatigued frame plate allows micro-movement of the final drive assembly, transmitting vibration through the chassis at specific RPM ranges.
• Premature bearing wear in the differential: Misalignment caused by a deformed plate accelerates bearing failure, often detected during routine oil analysis showing increased metal particles.

Technical Specifications

Compatibility

This frame plate is designed for ZF’s WG series powershift transmissions commonly found in wheel loaders, graders, and telehandlers. Primary compatible models include WG180, WG200, and WG211 series. It also fits select 4WG-200 and 6WG-200 variants used in construction machinery from 2012 onward. Always verify the axle housing casting number before installation, as the 4699301085 COVER and 4699301014 THREAD PROTECTIVE SHIELD must match the same production batch for proper bolt alignment.
