ZF 5838.300.417 GEAR SHIFT FORK for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 5838.300.417 GEAR SHIFT FORK is a precision-machined component engineered for the WG100, WG130, and WG131 heavy-duty transmission series. This OEM genuine part directly actuates the sliding sleeves on the main shaft, enabling clean engagement and disengagement of gear ratios within the transmission housing. The SKU 5838.300.417 is forged from high-strength alloy steel to withstand repeated axial loads and friction during shift cycles. When installed alongside the 5838022003: REAR AXLE and the 5838109001: DIFFERENTIAL, this shift fork ensures synchronized power delivery from the gearbox to the driveline.

Symptoms of Failure

• Hard shifting or grinding gears: A worn shift fork cannot properly align the synchronizer hub, causing metal-on-metal contact during gear changes. This often manifests as a distinct grinding noise when moving from neutral into first or reverse.
• Gear pop-out under load: When the fork tines wear down, the sliding sleeve loses retention force, allowing the transmission to unexpectedly jump out of gear during acceleration or deceleration.
• Excessive transmission oil contamination: Fractured fork material can shed metallic debris into the gear oil, which accelerates wear on the 0750117075: TAPER ROLLER BEARING and other rotating assemblies.
• Stiff or notchy shift lever feel: A bent or cracked shift fork creates binding in the shift rail mechanism, requiring abnormal force to move the lever through the gate pattern.

Technical Specifications

Compatibility

This genuine ZF shift fork is specifically designed for the WG100, WG130, and WG131 transmission models. It also fits select variants of the WG180 and WG200 series when used with the correct shift rail assembly. The fork interfaces directly with the 5838300128: DIFFERENTIAL HOUSING mounting points. Always verify your transmission serial number before ordering.
