Overview
The ZF 0750.115.361 NEEDLE CAGE is a precision-engineered OEM genuine component designed to reduce rotational friction and support radial loads within the planetary gear sets of heavy-duty ZF transmissions. This needle cage sits directly between the main shaft and the gear assembly, ensuring smooth torque transfer and maintaining correct gear alignment under high-stress conditions. As a critical wear item, the SKU 0750.115.361 must be replaced with factory-spec parts to prevent premature failure of adjacent components such as the 2094104412: MAIN SHAFT and the 2094304054: MAIN SHAFT.
Symptoms of Failure
- Gear slipping under load: A worn needle cage allows excessive axial play, causing the gear train to lose engagement during operation.
- Metallic grinding noise from transmission: Failed needle rollers create debris that contaminates the oil, producing a distinct grinding sound during shifting.
- Oil contamination with metallic particles: As the cage deteriorates, small steel fragments appear in the transmission fluid, visible during routine oil changes.
- Hard shifting or gear lockout: Increased friction from a collapsed cage prevents the 2094106010: SHIFT SYSTEM from engaging gears smoothly.

Compatibility
This needle cage is primarily used in ZF WG180, WG200, and WG211 series construction machinery transmissions. It is also found in certain off-highway and agricultural drivelines where the 2094206001: GEARSHIFT SHAFT assembly requires low-friction support. Always verify your transmission model number before ordering.

Frequently Asked Questions
Q: How do I know if the 0750.115.361 needle cage is failing?
A: Listen for a high-pitched whine or rattle from the transmission housing, especially in neutral. Check your oil filter for metallic debris—this is a strong indicator of cage degradation.
Q: Can I reuse the old needle cage during a rebuild?
A: No. The needle cage is a single-use component. Reusing it risks uneven roller wear, which can damage the main shaft and shift system. Always install a new OEM 0750.115.361 part.
Q: Does this part fit ZF WG180 transmissions?
A: Yes, the 0750.115.361 is compatible with WG180, WG200, and WG211 models. However, we recommend cross-referencing your transmission serial number with the 2094304054: MAIN SHAFT to confirm fitment.
