ZF 2094.346.009 END SHIM | OEM Genuine Part

Overview

Precision axial clearance is critical for the longevity of any heavy-duty transmission. The ZF 2094.346.009 END SHIM functions as a precision spacer, establishing the correct end-play for gear clusters and shafts within the planetary gear sets. This OEM genuine part, SKU 2094.346.009, is installed at the terminal end of a shaft assembly to absorb thrust loads and prevent lateral movement. Without this shim, the entire rotating assembly loses its dimensional stability, leading to accelerated wear on bearings and synchronizers. It is a non-negotiable component during any rebuild of a ZF construction machinery transmission.

Symptoms of Failure

When the ZF 2094.346.009 END SHIM wears or is omitted during service, specific mechanical failures emerge. Operators searching for “transmission end play noise” or “gear cluster wobble” will find the root cause here.

• Excessive Axial Play: A distinct clunking sound when shifting from forward to reverse, indicating the main shaft is moving beyond its tolerance.
• Premature Bearing Failure: Worn shims allow the shaft to hammer against the bearing races, causing a low-frequency rumble that escalates over time.
• Oil Contamination from Metal Debris: As the shim surface erodes, fine metallic particles enter the hydraulic circuit, clogging valves and reducing clutch pack pressure.
• Gear Slipping Under Load: Incorrect end-play allows gear engagement depth to change, resulting in partial disengagement and power loss during heavy digging operations.

Compatibility

This end shim is engineered for ZF’s heavy-duty powershift transmission series used in construction machinery. It is a direct fit for the WG180, WG200, and WG211 transmission models. These units are commonly found in wheel loaders, graders, and telehandlers from manufacturers such as Volvo, Case, and JCB. Always verify the stack height during assembly, as this shim is often paired with a SNAP RING (0630513070) to lock the assembly in place.

During a full rebuild, this shim works in concert with the MAIN SHAFT (2094104412) and the MAIN SHAFT (2094304054) to establish the correct running clearance. The SHIFT SYSTEM (2094106010) and GEARSHIFT SHAFT (2094206001) must also be inspected for wear when replacing this shim, as axial movement can damage their engagement forks.

Frequently Asked Questions

Q: Can I reuse the old ZF 2094.346.009 END SHIM during a rebuild?
A: No. This shim is a wear item that compresses over time. Reusing it will result in incorrect end-play, leading to premature bearing failure. Always install a new OEM shim.

Q: How do I measure the correct shim thickness for my WG200 transmission?
A: Use a depth micrometer to measure the housing bore depth, then subtract the shaft shoulder height. The difference must be between 0.10 mm and 0.25 mm. Select the 2094.346.009 shim that brings the stack into this tolerance.

Q: Is this shim compatible with the ZF 4WG-200 model?
A: Yes. The 2094.346.009 is used in the 4WG-200, 4WG-180, and 4WG-211 series. It fits the output shaft end-play adjustment location.
