ZF 2093.298.068 PTO SH.CLUTCH for WG100/WG130/WG131 | OEM Genuine Part

Overview

This genuine OEM ZF 2093.298.068 PTO SH.CLUTCH is a critical power take-off shift clutch designed specifically for the WG100, WG130, and WG131 transmission series. It serves as the primary engagement mechanism for the PTO system, allowing operators to seamlessly transfer engine torque to auxiliary hydraulic pumps or driven equipment. The SKU 2093.298.068 sits directly within the transmission housing, interfacing with the differential assembly to control power distribution. When this clutch engages, it locks the PTO shaft to the transmission output, enabling reliable operation of dump bodies, winches, or other hydraulic systems. As an OEM genuine part, it ensures exact fitment and factory-specified clamping force for consistent performance in heavy-duty industrial applications.

Symptoms of Failure

• PTO engagement slippage under load: When the shift clutch wears, the friction material loses grip, causing the PTO to slip or disengage unexpectedly when operating hydraulic pumps or heavy equipment. This often manifests as a loss of hydraulic pressure or slow implement response.
• Grinding or harsh engagement noise: A worn 2093.298.068 clutch produces metallic grinding sounds during PTO activation, particularly when shifting from neutral to engaged position. This indicates damaged splines or worn friction surfaces.
• Oil contamination from clutch debris: As the shift clutch deteriorates, friction material particles contaminate the transmission fluid, visible as dark metallic sludge in the oil filter or drain plug. This accelerates wear on adjacent components like the 2093109013: DIFFERENTIAL.
• Intermittent PTO failure to engage: A failing shift clutch may require multiple attempts to engage, or the PTO lever may feel loose or unresponsive, indicating broken return springs or seized clutch plates.

Technical Specifications

Compatibility

This genuine ZF 2093.298.068 PTO shift clutch is engineered for direct installation in the following transmission models: WG100, WG130, WG131. It is also compatible with WG180 and WG200 series transmissions when used with the appropriate 2093309073: DIFF.HOUSING adapter. The clutch interfaces with the 2093209096: DIFFERENTIAL assembly and requires proper shimming with a 0750117075: TAPER ROLLER BEARING for correct end-play. Always verify your transmission serial number before ordering to ensure exact fitment.

Frequently Asked Questions

Q: Can I install the 2093.298.068 clutch without replacing the differential bearings?
A: It is strongly recommended to replace the 0750117075: TAPER ROLLER BEARING simultaneously, as worn bearings cause misalignment that accelerates clutch wear. Always inspect the 2093309073: DIFF.HOUSING for scoring before reassembly.

Q: What is the expected service life of this PTO shift clutch?
A: Under normal operating conditions with proper lubrication, the 2093.298.068 clutch typically lasts 3,000-5,000 hours. Frequent PTO cycling under full load reduces this interval. Monitor for the failure symptoms listed above to schedule proactive replacement.

Q: Does this part include the necessary shims and snap rings?
A: The 2093.298.068 is sold as the clutch assembly only. You will need to order the 0631100223: SPRING PIN and 0730300820: THRUST WASHER separately for complete installation. Refer to your ZF service manual for shim specifications.
