Banjo Gear oil Question. 1 Attachment(s)
I would appreciate it if a Fordbarner would give an explanation of what the little passageway on the end of the torque tube is for and how it functions.
I think it's related to rear gear oil flow. You can see the upside down "U" Shaped passageway in the upper right of center in the photo. Thank you. JIM |

Re: Banjo Gear oil Question. From what I gather it should be installed on the bottom and allows the gear oil to return to the diff when it passes thru the pinion double bearings.

Re: Banjo Gear oil Question. I understood the passage has to be kept open, gasket also aligned, to provide run-back of oil as well as venting up torque tube so wheel seals will not leak.

Re: Banjo Gear oil Question. Most rear axles have a vent built into them, the original Ford banjos got away without one because of the volume of air between the axle itself and the torque tube. One of the things that is often done with a quick change modification is the addition of a vent on the axle housing. Gears turning and heat can generate a lot of pressure and this pressure will tend to force the gear lube past the seals, thus the need for vents. But again, Ford relied on the volume of air in the torque tube to buffer the pressure in the axle housing.

Re: Banjo Gear oil Question. Mr. Seery, Thanks for adding that tid bit of helpful knowledge.

Re: Banjo Gear oil Question. Also if you install a Mitchell overdrive, you should vent the axle due to much shorter torque tube between the banjo and the Mitchell gearbox.
