Procedure for filling a rebuilt columbia axle
 

Hi everyone. Can anyone please explain the procedure for filling a Columbia axle that has been rebuilt and is completely empty. I can’t seem to find the instructions, it was a real safe spot I put them in! Thanks Dan.

"LUBRICATION INSTRUCTIONS – IMPORTANT

With rear wheels off of floor fill rear axle through filler hole in Two-Speed Axle housing with 4½ Pints of standard Ford rear axle lubricant. (DO NOT USE CUP GREASE ) Start motor, shift transmission into high, and Two-Speed Axle control valve in high, depress clutch pedal to floor board, which completes shift in rear axle. Allow clutch pedal to return and run five minutes in this position. This is for the purpose of circulating oil through the entire Two-Speed Axle Unit. Next remove jack and with wheels on floor, BE SURE to refill axle to new oil level plug."

I just changed my fluid. For the refill it took 4 pints however I am not able to run it as above to see if it needs to be topped off.

The internal planetary gears get lubed only by the oil slung off the rotating assembly ,guided by ridges, baffles into the planet gearcase this is the reason for running it no load when first installed and rechecking, once it has been run and filled it won’t drain during a oil change unless it has been modified somehow

So guys is all the oil only added into the Columbia side and no need to add anything into the ford side of the axle?

Correct, don’t use the filler plug in the banjo , use the filler plug in the Columbia unit. The only exception to this is for the Lincoln with the Hypoid rear. A true Zephyr A-6 housing has no filler plug like the Ford unit. But the two will interchange. If a Zephyr A-6 is to be used on a Ford then a filler hole needs to be drilled but a Ford on a Zephyr just don’t use the plug. Here’s a couple I have. Note the difference.
