Overview
The ZF 2093.310.148 SPUR GEAR is a precision-machined component engineered for the auxiliary drive and power take-off (PTO) gear train within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part transmits rotational force from the input shaft to the differential assembly, ensuring smooth torque distribution under heavy loads. The SKU 2093.310.148 is manufactured to ZF’s exacting tolerances, featuring case-hardened steel construction for extended service life in demanding industrial applications. When installed alongside a 2093109028: DIFFERENTIAL, this spur gear forms the critical link between the transmission’s main shaft and the final drive system.
Symptoms of Failure
- Whining or grinding noise during gear engagement: Worn teeth on the 2093.310.148 produce a high-pitched whine that intensifies under load, often mistaken for differential noise. This indicates surface fatigue or pitting on the gear flanks.
- Intermittent power loss in forward gears: A failing spur gear causes the transmission to “skip” or momentarily lose torque delivery, particularly when climbing grades or towing. This symptom is frequently reported alongside a failing 0750117075: TAPER ROLLER BEARING.
- Metallic debris in transmission fluid: Flakes or silver particles found during oil changes confirm gear tooth spalling. Left unaddressed, this can damage the 2093209094: DIFFERENTIAL and require a full rebuild.
- Excessive backlash in the driveline: A clunking sensation when shifting from neutral to drive indicates worn gear teeth or a damaged 2093309078: DIFF.HOUSING.

Compatibility
This spur gear is specifically designed for ZF WG-series transmissions with a 100-131 mm gear center distance. Confirmed compatible models include:
- ZF WG100 (all variants)
- ZF WG130 (including WG130C and WG130E)
- ZF WG131 (with 4.11:1 or 4.56:1 final drive ratios)
It is not compatible with WG180 or WG200 series transmissions, which use a larger 6-module spur gear. Always verify the gear tooth count and bore diameter before installation.

Frequently Asked Questions
Q: Can I replace the 2093.310.148 spur gear without removing the transmission?
A: No. The gear is located inside the main transmission housing and requires removal of the PTO cover and differential assembly. We recommend replacing the 0750117075: TAPER ROLLER BEARING simultaneously due to shared load paths.
Q: What is the torque specification for the retaining nut on this gear?
A: ZF specifies 180 Nm (133 ft-lbs) for the M20x1.5 retaining nut. Always use a new 0631100223: SPRING PIN during reassembly to prevent loosening.
Q: How do I identify a counterfeit 2093.310.148 gear?
A: Genuine ZF parts have a laser-etched part number and a matte finish. Counterfeits often show grinding marks and weigh 10-15% less. Verify the bore diameter with a micrometer—it must measure exactly 35.000 mm.
