ZF 2095.310.030 SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.310.030 SHAFT (SKU: 2095.310.030) is a precision-machined component engineered for the internal gear train of ZF WG100, WG130, and WG131 transmissions. This shaft serves as a critical rotational axis within the countershaft assembly, transferring torque from the input gears to the differential system. As an OEM genuine part, it ensures exact fitment and load-bearing capacity to maintain the transmission’s power flow integrity. The 2095.310.030 shaft interfaces directly with the 2095109019: DIFFERENTIAL and the 2095209037: DIFFERENTIAL to synchronize gear engagement under heavy-duty cycles.

Symptoms of Failure

When the ZF 2095.310.030 shaft wears out, operators often notice these specific failure indicators:

• Transmission gear slipping under load – A worn shaft can cause misalignment between the countershaft and the 0750117075: TAPER ROLLER BEARING, leading to intermittent power loss during acceleration.
• Metallic grinding noise from the differential housing – Excessive play in the shaft creates contact with the 2095309059: DIFF.HOUSING, producing a distinct scraping sound at low speeds.
• Oil leaks near the shaft seal area – Surface wear on the shaft journal degrades the sealing surface, allowing transmission fluid to escape and contaminating the clutch pack.
• Vibration in the driveline during gear changes – A bent or fatigued shaft induces harmonic oscillations that resonate through the entire powertrain, often misdiagnosed as a bearing issue.

Technical Specifications

Compatibility

This shaft is specifically designed for ZF WG-series transmissions. Verified compatibility includes the following models:

• ZF WG100 (all variants)
• ZF WG130 (standard and heavy-duty)
• ZF WG131 (low-ratio configurations)
• ZF WG180 (with adapter modifications – confirm fitment)
• ZF WG200 (select applications – check spline engagement)

For proper assembly, this shaft must be paired with the 0750117075: TAPER ROLLER BEARING and the 2095309059: DIFF.HOUSING to ensure correct axial preload.
