Overview
The ZF 2094.306.029 GEAR SHIFT FORK is a precision-engineered component designed to actuate the sliding sleeves within the WG100, WG130, and WG131 transmission assemblies. This OEM genuine part, identified by SKU 2094.306.029, sits directly on the gearshift shaft and interfaces with the synchronizer hubs to engage specific gear ratios. By transferring lateral motion from the shift system to the synchronizer, this fork ensures smooth, positive gear engagement without binding. It is a critical wear item in heavy-duty ZF gearboxes, often replaced alongside the 2094104412: MAIN SHAFT and 2094106010: SHIFT SYSTEM during a major overhaul.
Symptoms of Failure
- Hard shifting or gear clash: When the fork pads wear unevenly, the synchronizer cannot align properly, causing grinding noises during engagement.
- Transmission jumping out of gear: A bent or worn fork fails to hold the sliding sleeve in position, leading to unexpected disengagement under load.
- Excessive shift lever play: Worn fork pivot points or a cracked fork body create slop in the shift linkage, making precise gear selection difficult.
- Oil contamination from metal debris: As the fork wears, fine metallic particles enter the transmission fluid, accelerating wear on the 2094304054: MAIN SHAFT and other internal components.

Compatibility
This gear shift fork is engineered for the ZF WG series of manual transmissions. It is a direct fit for the following models: WG100, WG130, WG131, WG150, WG180, and WG200. It is also compatible with certain variants of the ZF Ecomid and Ecolite series that share the same shift rail spacing. When replacing this fork, always inspect the mating 2094206001: GEARSHIFT SHAFT for wear, as a worn shaft will quickly damage a new fork.

Frequently Asked Questions
Q: How do I know if my ZF WG100 needs a new shift fork?
A: Listen for a metallic scraping sound when shifting into 3rd or 4th gear. Also check for excessive lateral movement in the shift lever when the transmission is in neutral—this indicates worn fork pads.
Q: Can I reuse the old snap ring when installing this fork?
A: No. Always replace the 0630513070: SNAP RING during installation. A reused snap ring may lose tension and allow the fork to slide off the shaft, causing catastrophic internal damage.
Q: Is this fork compatible with the ZF WG180?
A: Yes, the 2094.306.029 is a direct fit for WG180 transmissions, provided the shift rail diameter matches 28 mm. Always verify by measuring the existing fork bore before ordering.
