ZF 2094.298.064 REPAIR KIT | OEM Genuine Part

Overview

The ZF 2094.298.064 REPAIR KIT (SKU: 2094.298.064) is an OEM genuine service assembly designed to restore the internal sealing and actuation integrity of ZF construction machinery transmissions. This kit contains all critical wear components—including gaskets, O-rings, and specialized seals—that interface directly with the main shaft housing and shift rail bores. When installed, it prevents hydraulic fluid bypass between the clutch packs and the gearshift mechanism, ensuring consistent pressure delivery. This repair kit is a mandatory replacement item whenever the transmission is opened for overhaul, as it directly mates with the 2094104412 MAIN SHAFT and the 2094106010 SHIFT SYSTEM to maintain a leak-free environment.

Symptoms of Failure

When the ZF 2094.298.064 repair kit deteriorates, operators will notice distinct operational issues. Look for these specific failure modes:

• External oil seepage at the shift housing joint – A common long-tail search query: “ZF transmission oil leak between main case and shift cover.” This occurs when the included seals lose elasticity.
• Erratic gear engagement or delayed shifting – Worn seals inside the kit allow cross-port leakage, causing the 2094206001 GEARSHIFT SHAFT to receive inconsistent pilot pressure.
• Low hydraulic pressure readings on the clutch circuit – Internal weeping past the repair kit’s piston seals reduces overall system pressure by 15-20%.
• Contaminated transmission fluid with metallic debris – As the kit fails, fine wear particles from the 2094304054 MAIN SHAFT can bypass the filtration path.

Technical Specifications

Compatibility

This repair kit is engineered for ZF’s heavy-duty powershift transmission series used in construction machinery. It is a direct fit for the following models:

• ZF WG180 – All variants (WG180, WG180C, WG180E)
• ZF WG200 – Standard and high-torque versions
• ZF 4WG-180 – Four-speed countershaft designs
• ZF 4WG-200 – With integrated torque converter

Always verify the serial number of your transmission housing before ordering. The kit replaces the original seal set and is not backward-compatible with pre-1990 WG series units.
