Overview
The ZF 2093.310.061 CYLINDER | OEM Genuine Part is a precision-engineered hydraulic actuation component designed for heavy-duty construction machinery transmissions. This cylinder plays a critical role in modulating clutch pack engagement within the transmission valve body, converting hydraulic pressure into linear mechanical force. As an OEM genuine part (SKU: 2093.310.061), it ensures factory-specified clearances and sealing integrity, directly influencing shift quality and torque transfer efficiency. This cylinder is frequently replaced alongside the 2093109006: DIFFERENTIAL and the 2093209095: DIFFERENTIAL during major transmission overhauls.
Symptoms of Failure
- Hydraulic fluid seepage around the transmission housing: Worn piston seals or bore scoring in the 2093.310.061 cylinder cause external oil leaks, often visible as drips near the valve body.
- Delayed or harsh gear engagement: Internal leakage reduces actuation pressure, leading to clutch pack slippage and a noticeable lag when shifting from neutral to drive.
- Erratic shift timing under load: A failing cylinder cannot maintain consistent stroke length, resulting in unpredictable shift points during excavation or grading operations.
- Increased transmission operating temperature: Slipping clutches generate excess heat; a defective 2093.310.061 cylinder is a common root cause in overheated ZF units.

Compatibility
This cylinder is engineered for ZF’s WG-series powershift transmissions commonly found in wheel loaders, telehandlers, and graders. It is a direct fit for the WG180, WG200, and WG211 models. The 2093.310.061 also integrates with the 2093309071: DIFF.HOUSING assembly and works in concert with the 0750117075: TAPER ROLLER BEARING to maintain axial load stability. Always verify your transmission serial number before ordering.

Frequently Asked Questions
Q: Can the 2093.310.061 cylinder be repaired with a seal kit?
While seal replacement is possible, the OEM cylinder bore is precision-honed. We recommend replacing the entire unit if bore wear is detected, as aftermarket seals often fail prematurely.
Q: What torque specification applies to the mounting bolts for this cylinder?
ZF specifies 45 Nm (33 ft-lbs) for the M8 bolts securing the 2093.310.061 to the valve body. Always use a thread locker rated for hydraulic fluids.
Q: Does this cylinder fit ZF 4WG-200 transmissions?
Yes, the 2093.310.061 is a direct replacement for the 4WG-200 series. However, confirm your transmission’s build date; units before 2010 may require the 0631100223: SPRING PIN adapter.
