I have grease leaking from around the rear hub, I've bought new leather oil seals, felts, a sleeve puller and hub puller. In order to refurbish the hub are there any simple illustrations that would aid the task?
Use the new Neoprene inner seals, pull bearing and the sleeve put these on behind and reinstall what you took out.
John is right. Forget the leather seals and use neoprene. Here's a video showing installation with the axle out of the car. With it in the car, it's about the same.
I used the neoprene seals and standard 90 wt gear lube. No leaks yet!
Obviously I need to go down the Neoprene route, but what is the easiest way to get the old leather seal out without causing damage? The Youtube video is very helpful, many thanks.
Assume the old seal is toast. With the bearing and sleeve removed, hook the old seal and pull it out. I'd try a piece of wire coat hanger for a hook. If that's not a strong enough hook, heat the end of a junk screwdriver orange and make a hook of the blade. Your hook has to be small enough to get past the leather, but big enough to grab the other side of the seal.
Ian, We manufacture the neoprene seals. Mac's Antique auto copied our seal but they copied the old design. Our new design is better. The leather seals are ok but you have to shorten the metal spring fingers so they rest on the leather and not the axle.
I think the real issue is going to be how worn are your axles, bearings and sleeves. Most old T's have considerable wear at the outboard end of the axle. Slop out there makes it really difficult for any seals to do a good job (leather or neoprene).
After you have removed the wheel see how much movement vertically the axle can have. I have seen lots where there is 1/16" or more. This is tough for any seal to deal with well.
Personally I have found that the leather seals are more tolerant of less than perfect surfaces where the seal runs. Neoprene seals require a really good surface where the seal runs in my experience.
Often times as well people run too much oil in the rear axle which aggrevates the situation. I see you have a '23 with a small brake drum rear axle. On the 26-7 cars Ford relocated the oil fill hole lower down a good inch to reduce the amount of oil getting to the outboard bearings. I run the oil in my '13 at a level where I can just touch it with my finger tip if I dip it through the fill hole
Les -- That is all good advice. And I don't mean to seem too picky, but I believe the filler hole was lowered in the '19 model year.
Ian -- The Ford Service book says to use 1-1/4 pounds (pints) of lube in the rear end.
Mike is right. The filler plug is about 1 1/2" below the center line staring in 1919. Also the housing halves are machined for a gasket. Had to change out my 1919 roadster- had later rear end. So fill to the plug hole if it is below the center line.
