ZF 2094.247.026 MANIFOLD | OEM Genuine Part

Overview

The ZF 2094.247.026 MANIFOLD is a critical hydraulic distribution component within the valve body assembly of heavy-duty ZF powershift transmissions. This OEM genuine part precisely routes pressurized oil to clutches and lubrication circuits, ensuring proper shift timing and torque converter lock-up. The SKU 2094.247.026 is machined from high-tensile cast iron to withstand sustained hydraulic pressures exceeding 20 bar. When installed correctly, this manifold works in concert with the 2094104412: MAIN SHAFT and the 2094304054: MAIN SHAFT to maintain consistent oil flow across all gear stages.

Symptoms of Failure

• External hydraulic oil leaks around valve body: Worn sealing surfaces on the 2094.247.026 manifold cause pressurized ATF to weep past O-rings, leaving visible drips on the transmission housing. This is a common “ZF manifold oil leak” search query.
• Erratic or delayed gear engagement under load: Internal cracks or debris in the manifold passages starve specific clutch packs, leading to “ZF transmission slipping in forward gears” complaints.
• Torque converter shudder during lock-up: A failing manifold disrupts the pilot pressure to the lock-up valve, producing a “ZF torque converter vibration at highway speed” symptom.
• Elevated transmission operating temperature: Restricted oil flow through a damaged manifold forces the cooler circuit to work harder, triggering “ZF transmission overheating in excavator” warnings.

Technical Specifications

Compatibility

This manifold is engineered for ZF’s WG series powershift transmissions commonly found in construction machinery. It is a direct fit for the WG180, WG200, and WG210 models. The 2094.247.026 also appears in select 4WG200 and 5WG210 variants used in wheel loaders and telehandlers. Always verify your transmission serial number against the OEM parts catalog before ordering. For complete assembly, pair this manifold with the 2094106010: SHIFT SYSTEM and the 2094206001: GEARSHIFT SHAFT to restore full shift precision.

Frequently Asked Questions

Q: Can I reuse the old O-rings when installing the 2094.247.026 manifold?
A: No. Always replace all sealing rings and gaskets when swapping this manifold. Old elastomers will cause immediate external leaks and pressure loss, negating the benefit of a new manifold.

Q: How do I know if my ZF WG200 needs this specific manifold?
A: Check the casting number on the side of your existing manifold. If it reads 2094.247.026, this is the direct OEM replacement. If the number differs, consult your transmission model code to confirm compatibility.

Q: What causes internal cracking in this manifold?
A: The most common cause is thermal shock from rapid cooling after high-load operation, or overtightening of mounting bolts beyond the specified 45 Nm torque. Always use a calibrated torque wrench during installation.
