Overview
The ZF 2093.310.060 CYLINDER (SKU: 2093.310.060) is a precision-machined hydraulic actuation component engineered for heavy-duty construction machinery transmissions. This OEM genuine part functions as the primary force-transmission element within the clutch pack assembly, converting hydraulic pressure into linear motion to engage or disengage gear sets. Positioned directly inside the transmission valve body, the cylinder interfaces with the 2093109002: DIFFERENTIAL to ensure smooth torque distribution under extreme loads. Manufactured to ZF’s exacting tolerances, the 2093.310.060 cylinder guarantees leak-free operation and consistent shift quality in demanding environments like excavators and wheel loaders.
Symptoms of Failure
- Hydraulic oil leaks around the transmission housing – Worn cylinder seals cause visible fluid seepage, often mistaken for gasket failure. This is a common “ZF transmission oil leak” issue.
- Delayed or harsh gear engagement – A failing cylinder cannot maintain proper pressure, leading to “transmission slipping when shifting” or abrupt clutch application.
- Erratic clutch pack operation – Internal scoring on the cylinder bore results in “intermittent power loss under load,” particularly during low-speed maneuvering.
- Increased operating noise from the differential area – A collapsed cylinder can cause misalignment, producing a “whining noise from ZF differential” during turns.

Compatibility
This cylinder is designed for ZF’s WG180, WG200, and WG211 series powershift transmissions commonly found in construction machinery. It is also compatible with select ZF 4WG-180 and 4WG-200 variants used in telescopic handlers and graders. For proper fitment, verify your transmission serial number against the OEM parts catalog. The cylinder works in tandem with the 2093209095: DIFFERENTIAL and the 2093309071: DIFF.HOUSING to maintain drivetrain integrity.

Frequently Asked Questions
Q: Can the ZF 2093.310.060 cylinder be rebuilt instead of replaced?
A: While seal kits exist, the hardened bore surface is prone to wear. For construction machinery under heavy loads, we recommend OEM replacement to avoid recurring failures.
Q: How do I confirm this cylinder fits my ZF WG200 transmission?
A: Check the casting number on your transmission housing. The 2093.310.060 is standard for WG200 models built after 2015. Always cross-reference with the 0750117075: TAPER ROLLER BEARING compatibility chart for your specific unit.
Q: What torque is required for the cylinder mounting bolts?
A: ZF specifies 45 Nm for M8 bolts. Overtorquing can distort the cylinder bore, leading to piston seizure. Always use a calibrated torque wrench.
