ZF 2095.346.101 SPUR GEAR for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.346.101 SPUR GEAR is a critical power transmission component engineered for the WG100, WG130, and WG131 series transmissions. This OEM genuine part functions as a precision-ground gear that transfers torque from the input shaft to the countershaft assembly, ensuring smooth engagement and consistent rotational speed under heavy loads. The SKU 2095.346.101 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn or damaged gears in these specific transmission models. When installed alongside a properly functioning 2095109013: DIFFERENTIAL, this spur gear maintains the correct gear mesh and load distribution across the drivetrain.

Symptoms of Failure

• Whining or howling noise during acceleration: A worn 2095.346.101 spur gear produces a distinct high-pitched whine that increases with engine RPM, often mistaken for differential noise. This occurs when gear teeth develop pitting or uneven wear patterns.
• Intermittent gear slippage under load: When the spur gear’s tooth profile degrades, the transmission may momentarily lose power delivery during uphill climbs or heavy towing, causing a brief “skip” sensation.
• Metallic debris in transmission fluid: Flakes or fine metallic particles found during oil changes indicate advanced wear of the spur gear surface, often accompanied by damage to the 0750117075: TAPER ROLLER BEARING that supports the gear shaft.
• Vibration through the gearshift lever: Excessive backlash from a worn spur gear transmits vibration directly into the cab, especially noticeable at cruising speeds between 45-55 mph.

Technical Specifications

Compatibility

This spur gear is specifically designed for ZF’s WG-series mechanical transmissions. It is a direct fit for the WG100, WG130, and WG131 models, which are commonly found in medium-duty trucks, agricultural tractors, and construction equipment. The gear also interfaces with the 2095209037: DIFFERENTIAL assembly in these transmissions. For WG180 or WG200 models, verify the tooth count and shaft diameter before installation, as these larger units may require the 2095309059: DIFF.HOUSING variant.
