ZF 2094.313.061 INNER DISK CARRIER | OEM Genuine Part

Overview

The ZF 2094.313.061 Inner Disk Carrier is a precision-machined component located within the clutch pack assembly of heavy-duty ZF powershift transmissions. This OEM genuine part functions as the structural hub that houses and aligns the inner friction disks, ensuring consistent torque transfer between the rotating drum and the gear train. The SKU 2094.313.061 is engineered to withstand extreme thermal and mechanical loads found in construction machinery such as wheel loaders, dozers, and graders. Without a properly seated inner disk carrier, the entire clutch pack loses its geometric integrity, leading to uneven wear across the transmission.

Symptoms of Failure

• Delayed gear engagement under load: When the 2094.313.061 carrier warps or develops spline wear, the inner disks cannot seat correctly, causing a noticeable lag when shifting from neutral to drive in heavy equipment.
• Metallic grinding noise during clutch modulation: A worn inner disk carrier allows the friction disks to oscillate radially, producing a distinct grinding sound that intensifies as the transmission oil temperature rises.
• Intermittent loss of forward or reverse drive: If the carrier’s locating lugs fracture, the clutch pack may slip intermittently, often misdiagnosed as a hydraulic pressure issue.
• Contaminated transmission oil with bronze or steel particles: Advanced carrier degradation sheds material into the lubrication circuit, which can be detected during routine oil sampling.

Compatibility

This inner disk carrier is primarily designed for ZF WG180 and WG200 series powershift transmissions commonly installed in construction machinery from manufacturers such as Liebherr, Caterpillar, and Volvo CE. It also fits select ZF 4WG-200 and 4WG-210 variants used in telescopic handlers and compact loaders. Always verify the spline count and clutch pack stack height against your transmission’s service manual before installation.

Installation Context

During a clutch pack rebuild, the 2094.313.061 Inner Disk Carrier is mounted directly onto the 2094104412 MAIN SHAFT and aligned with the 2094304054 MAIN SHAFT to ensure concentric rotation. The carrier interfaces with the 2094106010 SHIFT SYSTEM which actuates the clutch piston, while the 2094206001 GEARSHIFT SHAFT provides the mechanical linkage for gear selection. Proper torque sequencing of these components is critical to prevent axial play.

Frequently Asked Questions

Q: Can the 2094.313.061 Inner Disk Carrier be reused after a clutch burn?
A: No. Thermal damage from a burned clutch pack will distort the carrier’s spline geometry and hardening. Always replace the carrier when friction material has delaminated.

Q: What is the torque specification for the retaining nut on this carrier?
A: For the WG180 series, the main shaft nut should be torqued to 450 Nm ± 20 Nm, then rotated 60 degrees further. Always consult the ZF service bulletin for your specific transmission model.

Q: Does this carrier fit the ZF 4WG-210 transmission?
A: Yes, the 2094.313.061 is compatible with the 4WG-210, provided the clutch pack uses 6 inner disks. Verify your stack height with a dial indicator before assembly.
