ZF 6606.313.010 ADJUSTING SCREW for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 6606.313.010 ADJUSTING SCREW is a precision-machined OEM genuine component engineered for the WG100, WG130, and WG131 transmission series. This critical fastener governs the axial play and preload within the clutch pack or planetary gear assembly, ensuring consistent hydraulic pressure distribution and smooth gear engagement. As a Springs & Fasteners category item, the SKU 6606.313.010 directly interfaces with the 2094101012 TRANSMISSION HOUSING and the 2094301036 HOUSING to maintain precise alignment under high-torque loads. Without this adjusting screw, the entire shift timing sequence becomes unpredictable, leading to premature wear on adjacent components.

Symptoms of Failure

• Erratic gear engagement or delayed shifting: When the adjusting screw loses its set torque, internal clearances widen, causing clutch packs to slip during acceleration.
• Low hydraulic pressure warnings: A worn screw allows the valve body or piston to shift out of tolerance, triggering pressure drops that are detectable via diagnostic scan tools.
• Metallic rattling from the bell housing: Excessive axial play from a loose adjusting screw permits planetary gears to chatter against the 2094298057 HOUSING.
• Oil contamination with fine metal particles: As the screw threads degrade, micro-fragments circulate through the transmission fluid, accelerating wear on seals and bearings.

Technical Specifications

Compatibility

This adjusting screw is specifically validated for ZF WG-series transmissions including the WG100, WG130, and WG131 models. It is also commonly used in the WG180 and WG200 series where the same clutch housing geometry applies. Always verify that the 2094301071 COVER is properly aligned during installation to avoid cross-threading. For applications in WG150 or WG250 variants, consult the parts manual to confirm thread pitch compatibility.

“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “No. ZF recommends replacing the adjusting screw with a new OEM part (6606.313.010) during any rebuild because the threads stretch and lose torque retention after initial use.”
