Overview
The ZF 2093.352.047 ORIFICE is a precision-engineered hydraulic flow control component designed to regulate oil pressure and volume within ZF powershift transmissions. Positioned within the valve body or clutch circuit, this OEM genuine part ensures consistent lubrication and cooling for planetary gear sets. The SKU 2093.352.047 acts as a calibrated restrictor, maintaining optimal hydraulic balance during load shifts. When paired with a 5838109012: DIFFERENTIAL, it stabilizes torque distribution across the driveline, reducing thermal stress on internal components.
Symptoms of Failure
- Erratic clutch engagement: A worn orifice causes delayed or harsh shifting, often described as “transmission hesitation” during acceleration.
- Oil starvation whine: Reduced flow leads to a high-pitched noise from the differential housing, especially under load.
- External seepage at valve body: Cracks in the orifice bore allow ATF to weep, leaving visible residue on the transmission casing.
- Overheating in low-range operation: Insufficient lubrication accelerates wear on the 0750117075: TAPER ROLLER BEARING, causing localized hot spots.

Compatibility
This orifice is primarily used in ZF WG180, WG200, and WG211 series transmissions found in construction machinery such as wheel loaders and telehandlers. It also fits select ZF 4WG-200 and 6WG-200 variants. For complete driveline restoration, consider replacing the 2093209023: DIFFERENTIAL and 5838300626: DIFFERENTIAL HOUSING simultaneously to prevent contamination from debris.

Frequently Asked Questions
Q: Can a clogged orifice cause transmission overheating?
A: Yes. A blocked 2093.352.047 restricts oil flow to the differential, leading to inadequate cooling of the 0750117075: TAPER ROLLER BEARING and subsequent thermal failure.
Q: How do I verify the orifice is genuine ZF?
A: Check for the etched “ZF” logo and part number 2093.352.047 on the hex shoulder. Counterfeits often have inconsistent thread pitch.
Q: Should I replace the differential housing gasket when installing this part?
A: Absolutely. Always install a new 5838300626: DIFFERENTIAL HOUSING seal to prevent debris ingress during orifice replacement.
