Overview
The ZF 2094.359.048 SPUR GEAR is a precision-machined component engineered for the auxiliary drive and power take-off (PTO) circuits within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part transfers rotational force from the main shaft to the oil pump and hydraulic system, ensuring consistent lubrication and clutch actuation pressure. The SKU 2094.359.048 is manufactured to ZF’s original tolerances, featuring case-hardened alloy steel for long service life under continuous load. When paired with the 2094104412 MAIN SHAFT and the 2094304054 MAIN SHAFT, this spur gear maintains precise gear mesh alignment critical for smooth power delivery.
Symptoms of Failure
- Whining or grinding noise from transmission housing — Worn gear teeth produce a high-pitched metallic sound during acceleration or deceleration, often mistaken for bearing failure.
- Intermittent oil pressure drops — A chipped or worn spur gear reduces pump efficiency, causing erratic hydraulic pressure and delayed clutch engagement.
- Metal debris in transmission fluid — Flaking or pitting on the gear face introduces ferrous particles into the oil, visible during routine drain intervals.
- Hard shifting or gear slippage — Insufficient hydraulic pressure from a failing gear leads to sluggish shifts and momentary loss of drive torque.

Compatibility
This spur gear is specifically designed for the ZF WG100, WG130, and WG131 series transmissions. It also fits select variants of the WG180 and WG200 models where the auxiliary drive configuration matches the 20 mm bore and 28-tooth count. Always verify the existing gear’s tooth profile and bore dimensions before ordering. The gear interfaces directly with the 2094106010 SHIFT SYSTEM and the 2094206001 GEARSHIFT SHAFT assembly to synchronize hydraulic flow with shift commands.

Frequently Asked Questions
Q: Can the 2094.359.048 spur gear be used in a ZF WG180 transmission?
A: Yes, it is compatible with WG180 models that share the same auxiliary drive layout. Confirm the bore diameter and tooth count match your existing gear before installation.
Q: What tools are needed to replace this spur gear?
A: A standard puller set, snap ring pliers, and a torque wrench are required. The gear is retained by a snap ring (part 0630513070) and sits on the main shaft assembly.
Q: How often should this gear be inspected?
A: Inspect during every major transmission overhaul (typically every 500,000 km or 10,000 operating hours). Look for pitting, chipping, or uneven wear patterns on the tooth flanks.
