Overview
The ZF 2093.368.094 SPUR GEAR is a precision-engineered component designed for the auxiliary drive and power take-off (PTO) gear train within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part transfers rotational force from the input shaft to the differential assembly, ensuring smooth torque distribution under heavy loads. The SKU 2093.368.094 is machined from case-hardened alloy steel to withstand continuous high-stress operation in commercial vehicles and off-highway equipment. When installed alongside the 2093109002: DIFFERENTIAL, this spur gear forms the critical link between the main shaft and the final drive reduction set.
Symptoms of Failure
- Whining or howling noise during acceleration: Worn gear teeth on the 2093.368.094 produce a distinct high-pitched whine that intensifies under load, often mistaken for differential noise. This indicates pitting or spalling on the tooth flanks.
- Intermittent PTO engagement failure: If the spur gear’s splines or teeth become chipped, the power take-off unit may fail to engage or disengage properly, causing erratic operation of hydraulic pumps or auxiliary systems.
- Metal particles in transmission oil: Advanced wear of the spur gear generates fine metallic debris visible during oil changes. This contamination accelerates damage to the 0750117075: TAPER ROLLER BEARING and other rotating elements.
- Vibration in neutral or low gear: A damaged spur gear creates uneven rotational mass, causing noticeable driveline vibration that worsens as the transmission warms up.

Compatibility
This spur gear is specifically engineered for the ZF WG100, WG130, and WG131 series transmissions used in medium-duty trucks, buses, and agricultural machinery. It is a direct replacement for the original gear in the auxiliary drive shaft cluster. While primarily designed for these three models, the 2093.368.094 may also be compatible with select WG180 and WG200 variants that share the same gear train architecture—always verify tooth profile and spline count before installation. For complete differential rebuilds, pair this gear with the 2093209095: DIFFERENTIAL and the 2093309071: DIFF.HOUSING to ensure proper alignment and load distribution.

Frequently Asked Questions
Q: Can the ZF 2093.368.094 spur gear be used in a WG180 transmission?
A: While the WG180 shares the same gear module, the tooth count and shaft diameter may differ. Always compare the bore diameter (35 mm) and tooth profile with your existing gear. We recommend consulting your ZF parts manual for WG180-specific applications.
Q: What torque specification should I use when installing this gear?
A: The spur gear itself does not require torque—it is press-fit or spline-mounted. However, the retaining nut on the shaft should be torqued to 180–220 Nm (depending on shaft size). Use a new 0631100223: SPRING PIN to lock the gear in place.
Q: How do I identify a worn spur gear without removing the transmission?
A: Listen for a rhythmic clicking sound that increases with engine RPM, and check the oil filter for metallic glitter. A borescope inspection through the PTO port can reveal tooth chipping without full disassembly.
