ZF 2098.346.016 END SHIM | OEM Genuine Part

Overview

The ZF 2098.346.016 END SHIM is a precision-engineered OEM genuine component designed to establish the correct axial clearance within the differential assembly of heavy-duty construction machinery transmissions. This hardened steel shim sits between the differential housing and the bearing race, ensuring that gear mesh patterns remain within factory tolerances. The SKU 2098.346.016 is critical for maintaining the preload on the differential bearings, directly influencing torque distribution and drivetrain longevity. Without this end shim, the entire differential assembly—including the 2098109042: DIFFERENTIAL and the 2098309011: CROWN WHEEL—cannot achieve the precise end-play required for smooth operation under load.

Symptoms of Failure

• Excessive differential bearing noise during turns: A worn or collapsed end shim allows the 2099209001: DIFFERENTIAL to shift axially, producing a distinct rumbling or growling sound when the machine maneuvers under load.
• Premature crown wheel and pinion wear: Incorrect shim thickness causes misalignment of the ring gear, leading to uneven tooth contact patterns and accelerated failure of the 2098309010: DIFFERENTIAL HOUSING.
• Oil leaks from the axle housing seals: Axial play from a degraded end shim forces the differential carrier to push against the seal lip, resulting in lubricant seepage around the output flanges.
• Intermittent gear slipping in high-torque applications: When the shim compresses beyond its elastic limit, the differential bearings lose preload, causing momentary loss of traction during excavation or grading operations.

Technical Specifications

Compatibility

This end shim is primarily used in ZF WG180, WG200, and WG250 series transmissions found in wheel loaders, graders, and telehandlers. It also fits select ZF 4WG-200 and 6WG-200 variants where the differential carrier uses a shim-adjustable bearing preload system. Always verify the existing shim stack thickness before replacement, as the 2098.346.016 is often used in combination with other shims to achieve the final clearance.
