ZF 2098.298.065 REPAIR KIT | OEM Genuine Part

Overview

The ZF 2098.298.065 REPAIR KIT (SKU: 2098.298.065) is a genuine OEM service assembly designed to restore sealing and bearing integrity within ZF heavy-duty transmissions used in construction machinery. This kit contains all necessary gaskets, O-rings, seals, and precision shims required to overhaul the differential housing and axle interface. It sits directly between the transmission output flange and the DIFFERENTIAL HOUSING, ensuring that lubricant remains contained under high torque loads. By replacing worn elastomers and metal components, this repair kit prevents contamination ingress and maintains correct gear mesh preload for the CROWN WHEEL assembly.

Symptoms of Failure

• Oil seepage around the differential housing flange: When the repair kit’s main seal degrades, transmission fluid escapes past the DIFFERENTIAL interface, leaving visible puddles under the machine.
• Gear whine or clunking during load shifts: Worn thrust washers inside the kit allow axial play in the DIFFERENTIAL assembly, causing misalignment of the bevel gear set.
• Contaminated transmission oil (metal particles): Failed seals permit dirt and moisture to enter the housing, accelerating wear on the crown wheel and pinion.
• Intermittent power loss under heavy load: Insufficient preload from degraded shims leads to clutch pack slippage in the transmission sump.

Technical Specifications

Compatibility

This repair kit is engineered for ZF WG180, WG200, and WG210 series powershift transmissions commonly found in wheel loaders, excavators, and telehandlers. It also fits select ZF 4WG-200 and 6WG-200 variants used in off-highway construction equipment. The kit is specifically designed to interface with the DIFFERENTIAL HOUSING (part 2098309009) and the AXLE BEVEL GEAR (2098309031). For complete differential overhaul, pair this kit with the AXLE BEVEL GEAR (2098309030) and DIFFERENTIAL BEVEL GEAR (2098309032).
