Overview
This genuine ZF 2093.310.176 SPUR GEAR is a critical power transmission component engineered specifically for the WG100, WG130, and WG131 series transmissions. Situated within the gear train assembly, this spur gear directly transfers rotational force from the input shaft to the intermediate shaft, ensuring smooth torque delivery under heavy industrial loads. The SKU 2093.310.176 is precision-machined to OEM tolerances, guaranteeing exact mesh alignment with mating gears and shafts. When installed alongside a 2093109029: DIFFERENTIAL, this spur gear forms the backbone of the transmission’s primary reduction stage, optimizing both fuel efficiency and driveline durability.
Symptoms of Failure
- Whining or howling noise during acceleration: Worn gear teeth create irregular contact patterns, producing a distinct high-pitched whine that intensifies under load. This often signals pitting or spalling on the tooth flanks of the 2093.310.176.
- Intermittent gear slipping under heavy torque: As the spur gear loses tooth profile integrity, it may momentarily lose engagement with the counter-shaft, causing sudden RPM surges without corresponding speed increase.
- Metallic debris in transmission oil: Flakes or fine silver particles in the fluid indicate advanced wear of the gear surface, often accompanied by scoring on the 0750117075: TAPER ROLLER BEARING that supports the gear shaft.
- Vibration through the gearshift lever: Excessive backlash from a worn spur gear transmits harmonic vibrations into the transmission housing, felt distinctly at cruising speeds.

Compatibility
This spur gear is designed for ZF WG-series transmissions, specifically the WG100, WG130, and WG131 models. These are commonly found in medium-duty trucks, agricultural tractors, and industrial material handlers. The 2093.310.176 also integrates with the 2093209094: DIFFERENTIAL assembly in WG131 variants, and its housing mates directly to the 2093309078: DIFF.HOUSING. While primarily for WG100/WG130/WG131, it may also fit WG180 and WG200 transmissions with minor shimming adjustments—always verify tooth count and shaft spline compatibility before installation.

Frequently Asked Questions
Q: How do I know if the 2093.310.176 spur gear is compatible with my WG130 transmission?
A: Verify your transmission’s serial number and gear ratio. This spur gear fits WG100, WG130, and WG131 models with a 34-tooth configuration. If your unit uses a different tooth count, consult the OEM parts catalog for the correct variant.
Q: Can I replace this spur gear without removing the entire transmission?
A: In most cases, partial disassembly of the gear train is required. You must remove the PTO cover and intermediate shaft to access the 2093.310.176. Always replace the 0750117075: TAPER ROLLER BEARING simultaneously to prevent premature wear on the new gear.
Q: What torque specification should I use for the retaining nut on this spur gear?
A: The recommended tightening torque is 180 Nm ± 10 Nm for the shaft nut securing the 2093.310.176. Always apply thread-locking compound (Loctite 243) and check backlash after installation—target 0.08–0.15 mm clearance.
