Overview
The ZF 0750.119.970 Axial Needle Cage is a precision-engineered OEM genuine component designed to manage axial thrust loads within the planetary gear sets of ZF BP210 and BP230 series transmissions. This needle roller cage sits between rotating shafts and stationary housings, reducing friction and ensuring smooth power transfer under heavy torque. The SKU 0750.119.970 is a direct replacement part that maintains factory tolerances, preventing premature wear on adjacent components like the 4681101002: TRANSMISSION HOUSING and the 4681201007: HOUS.FRONT SECT.
Symptoms of Failure
- Gear slipping under load: When the axial needle cage wears, the planetary gear set loses proper spacing, causing intermittent gear disengagement during acceleration.
- Metallic grinding noise from the transmission: A high-pitched whine or grinding sound, especially when shifting between forward and reverse, indicates the needle rollers have flattened or broken.
- Oil contamination with metallic debris: Worn needle fragments mix with transmission fluid, often visible as silver particles on the dipstick or during an oil change.
- Increased axial play in the output shaft: Excessive end-float measured at the yoke or flange suggests the cage can no longer contain the thrust loads.

Compatibility
This axial needle cage is specifically engineered for the ZF BP210 and BP230 series transmissions. It is also used in the WG180, WG200, and WG250 models where the same planetary gear carrier configuration is employed. The part interfaces directly with the 4681201008: HOUSING REAR PART and the 4681298001: CASE to maintain correct axial clearance. Always verify your transmission model code before ordering.

Frequently Asked Questions
Q: Can I reuse the old axial needle cage if it looks intact?
A: No. The 0750.119.970 cage is a wear item that should always be replaced during any transmission overhaul. Even minor surface wear can lead to axial play and eventual gear damage.
Q: Does this part fit the ZF WG180 transmission?
A: Yes. The 0750.119.970 is compatible with WG180, WG200, and WG250 models that share the BP210/BP230 planetary carrier design. Always cross-reference your transmission serial number.
Q: What tools are needed to install this needle cage?
A: Installation requires a bearing press and a drift tool sized to the cage outer diameter. Never hammer directly on the cage as it may distort the polymer retainer.
