Overview
The ZF 2093.310.038 SPUR GEAR is a precision-machined helical gear designed to transfer torque and rotational speed within the differential assembly of ZF’s heavy-duty transmission series. This OEM genuine part (SKU: 2093.310.038) sits directly on the differential side shaft, meshing with the ring gear to convert input shaft rotation into axle output. It is a critical component for maintaining smooth power delivery and load distribution in WG100, WG130, and WG131 gearboxes. When paired with a 2093109002: DIFFERENTIAL assembly, this spur gear ensures consistent gear mesh under high-torque conditions.
Symptoms of Failure
- Whining or grinding noise during acceleration – Worn gear teeth produce a high-pitched whine that intensifies under load, often indicating pitting or chipping on the spur gear face.
- Intermittent gear slipping under heavy torque – A failing 2093.310.038 spur gear can cause momentary loss of drive, especially when climbing grades or hauling heavy loads.
- Metal debris in transmission oil – Flakes or fine metallic particles found during oil changes point to advanced wear of the spur gear teeth or its mating 0750117075: TAPER ROLLER BEARING.
- Vibration through the driveline – Uneven tooth contact creates cyclical vibration felt in the chassis, often accompanied by a rhythmic “clunk” during deceleration.

Compatibility
This spur gear is engineered for ZF WG-series transmissions, specifically the WG100, WG130, and WG131 models. It is also compatible with the WG180 and WG200 series when used in conjunction with the correct 2093209095: DIFFERENTIAL carrier. For proper installation, always verify the spline count and shaft diameter against your existing 2093309071: DIFF.HOUSING to ensure a precise fit.

Frequently Asked Questions
Q: Can I use the ZF 2093.310.038 spur gear in a WG200 transmission?
A: Yes, it is compatible with WG200 models when paired with the correct differential housing (part 2093309071). Always check spline alignment before installation.
Q: What causes premature wear on this spur gear?
A: Common causes include insufficient lubrication, misalignment of the differential carrier, or a failing taper roller bearing (0750117075) that allows excessive gear movement.
Q: Is the 2093.310.038 supplied with a spring pin?
A: No, the spur gear is sold individually. You will need a separate spring pin (0631100223) to lock it onto the differential axle shaft.
