Overview
This OEM genuine ZF 0750.109.322 OIL TUBE is a critical fluid delivery component engineered specifically for the BP210 and BP230 series transmissions. Positioned within the valve body and main control assembly, this precision-machined tube channels pressurized hydraulic oil to the clutch packs and torque converter circuits. The SKU 0750.109.322 ensures a factory-spec fit, maintaining the exact flow rate and pressure required for smooth gear engagement. It works in concert with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to create a sealed hydraulic circuit, preventing cross-contamination between lubrication and control circuits.
Symptoms of Failure
- External hydraulic oil leaks: Cracks or corrosion on the tube surface cause visible drips near the bell housing or oil pan gasket area.
- Delayed or harsh gear engagement: A compromised oil tube reduces line pressure, leading to “flare shifts” or a noticeable lag when shifting from Neutral to Drive.
- Transmission overheating: Insufficient oil flow to the torque converter due to a restricted or damaged tube raises operating temperatures beyond normal limits.
- Low fluid level without visible external leaks: Internal cracking allows oil to bypass into the HOUSING REAR PART cavity, causing intermittent low-pressure warnings.

Frequently Asked Questions
Q: Can I install this oil tube without removing the transmission?
A: In most BP210/BP230 applications, the oil tube is accessible after dropping the oil pan and removing the valve body. However, on WG180 models, you may need to separate the HOUS.FRONT SECT for full access.
Q: What torque specification should I use for the retaining bolts?
A: Use 12 Nm for the cap screws (part 0636100801) and 25 Nm for the main housing bolts. Always replace the O-rings on the tube ends.
Q: Is this part interchangeable between BP210 and BP230 series?
A: Yes, the 0750.109.322 oil tube is physically identical for both series. However, verify the length against your existing tube if your transmission has a modified CASE from a previous rebuild.
