Overview
The ZF 2093.310.151 SPUR GEAR is a precision-engineered component designed for the auxiliary drive and power take-off (PTO) systems within the WG100, WG130, and WG131 transmission families. This OEM genuine part transfers rotational force from the input shaft to the differential assembly, ensuring smooth torque distribution under heavy loads. The SKU 2093.310.151 is manufactured to ZF’s exacting tolerances, featuring case-hardened steel construction that withstands continuous high-stress operation in industrial and agricultural machinery.
Symptoms of Failure
- Whining or grinding noise during PTO engagement: Worn gear teeth produce a distinct metallic sound, especially under load, indicating the 2093.310.151 spur gear requires replacement.
- Intermittent power loss to auxiliary systems: A damaged spur gear causes slippage in the driveline, leading to inconsistent hydraulic pump or winch performance.
- Metal debris in transmission fluid: Flaking or chipped teeth contaminate the oil, often visible during routine drain intervals, signaling imminent gear failure.
- Vibration through the gearshift lever: Uneven tooth wear creates harmonic oscillations that transmit into the cab, worsening as the gear degrades.

Compatibility
This spur gear is engineered for ZF WG-series transmissions, specifically the WG100, WG130, and WG131 models. It also integrates with the WG180 and WG200 variants when used in auxiliary drive configurations. The 2093.310.151 interfaces directly with the 2093109029 DIFFERENTIAL and the 0750117075 TAPER ROLLER BEARING to maintain axial alignment. For complete rebuilds, pair it with the 2093209094 DIFFERENTIAL and the 2093309078 DIFF.HOUSING to restore full driveline integrity.

Frequently Asked Questions
Q: How do I confirm the 2093.310.151 spur gear fits my WG130 transmission?
A: Verify your transmission serial number and check the gear count (18 teeth). This part is a direct OEM replacement for WG100, WG130, and WG131 models; for WG180 or WG200 units, confirm the auxiliary drive housing matches the 25.4 mm bore.
Q: Can I replace just the spur gear without replacing the differential?
A: Yes, but inspect the mating 2093109029 DIFFERENTIAL for wear. If the differential shows scoring or pitting, replace both components to prevent premature failure.
Q: What torque specification should I use for the retaining nut?
A: For the 2093.310.151 spur gear, tighten the retaining nut to 120 N·m (88 lb-ft) using a thread-locking compound. Always consult your ZF service manual for exact values.
