Overview
The ZF 2093.368.116 SPUR GEAR is a precision-engineered component designed for the auxiliary drive train within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part transfers rotational force between parallel shafts, ensuring smooth power delivery in heavy-duty industrial applications. As a critical element of the gear train, the spur gear (SKU: 2093.368.116) works in concert with the 2093101052 HOUSING to maintain correct gear mesh alignment. Its straight-cut teeth provide high efficiency and durability under constant load, making it indispensable for maintaining transmission integrity in demanding environments.
Symptoms of Failure
- Whining or grinding noise during operation: Worn teeth on the 2093.368.116 spur gear produce a distinct metallic sound, often mistaken for bearing failure. This noise intensifies under load and indicates advanced wear.
- Intermittent gear slipping or power loss: As tooth profiles degrade, the gear fails to maintain positive engagement, causing momentary loss of drive torque. This symptom is especially noticeable during acceleration or hill climbs.
- Metallic debris in transmission fluid: Flaking or chipped gear teeth shed particles that contaminate the oil. Inspecting the fluid for silver or bronze specks is a reliable diagnostic indicator of spur gear failure.
- Vibration through the gear lever or chassis: Uneven tooth wear creates rotational imbalance, transmitting vibrations that worsen as the gear continues to operate.

Compatibility
This spur gear is specifically engineered for ZF WG-series transmissions, including the WG100, WG130, and WG131 models. It is also compatible with the WG180 and WG200 series when used in auxiliary drive positions. The gear interfaces directly with the 2093298063 TRANSMISSION HOUSING and the 2093301069 TRANSMISSION HOUSING to ensure proper alignment. Always verify the 4475280015 SCREW PLUG is torqued correctly during installation to prevent oil leaks from the housing bore.

Frequently Asked Questions
Q: How do I confirm the 2093.368.116 spur gear is compatible with my WG130 transmission?
A: Check the transmission serial number plate (often the 0730365092 TYPE PLATE) to verify the model. This gear fits WG100, WG130, and WG131 units, but always measure the bore diameter (35 mm) and tooth count (28) against your existing gear.
Q: Can I replace just the spur gear without replacing the housing?
A: Yes, provided the 2093101052 HOUSING shows no cracks or wear. However, inspect the 0634304731 O-RING and replace it if hardened or flattened.
Q: What torque specification applies to the screw plug during installation?
A: Use 45 Nm for the 4475280015 SCREW PLUG. Over-torquing can distort the housing bore and cause premature gear wear.
