Super A axle seal, more help needed

RJV · Dec 16, 2009

I now have the right rear axle tube off the lower unit. Next step is to get the brake drum off the axle. How do you do that? I have the square set screw backed out. I see the woodruff key. The drum doesnt budge. How am I going to rig a puller for this? Do they make special ones? Do I pull the drum off with the key in or try to tap the key out? Im so close!!! Once the drum is slid off the axle, everything should push out the outside end, correct??

Thanks for all your help.

The key wont come out without removing brake drum first. Those drums can be a bitttttch i have had to cut some with a torch to remove. You are correct the drum has to come off first. Ifn you need any parts i would have them.

YOu're gopin at it right, Ron. Once the drum is off, it make take a light bump on the iside in to start it, but the shft will come out the outside end.

As far as the drum, Gene's got it right. In my experience if they don't come right off, they're a pain. Prybars, whatever ya got. Liquid Wrench might help, too, after ya clean off the gunk. Turn it and work your way around it it may be stuck harder in one spot than another. I had some luck with one heating at the inside end of the spokes so the heat went to the hub without heating the shaft. If you're handy with oxy acetylene, you'll have a sense of how much to use. If not, a bottle of Mapp gas on your propane torch would be good.

I have a puller i put through the slots on the drum and was able to pull it off. It was on a B but the brake drum is the same.

Removed mine a couple of weeks ago, came right off with a puller. As to being tight, mine had ample seal leaks to keep it lubricated. There is no "special" puller, I used a medium sized 2 jaw.

ScottyHOMeY · Dec 18, 2009

Now you've got me curious. I can see it on the left-side shaft, but what are you and Zach using for a jaw-type puller on the long, right-side shaft? I could see a home-built rig built on a pattern similar to the sleeve puller that's pictured now and then, but I'm thinkin' those would have to be some awful long jaws!

I cheated -- I used a large 2 jaw puller and extension parts from another one. It barely fit, but it worked. The long jawed sleeve puller would be better, as my combination is pretty sloppy.

In my previous post I said "medium size" puller, it's all relative. I need a bigger one.

ScottyHOMeY · Dec 18, 2009

Whew! Okay. That's probably a 20" reach or so when you take the length of the splined end of the shaft into consideration. Elegant method, but there's nothin' near that size for pullers in my tool heap or even in the chests.

Who makes the puller you used that offers extensions of the type you're talking about? I'm not in a tool buyin' situation of late, but wouldn't mind doin' my own online lookin' up to get a better picture of it in my feeble (alleged) mind. I might have to put it on my wish list. ;8^)

Thanks!

I don't know the name of the parts, they are the four flat metal pieces with bolt holes in each end that are on most all pullers. I simply borrowed them from another puller and added them to the existing ones, giving twice the depth. Now I don't remember what went with what.
Now if I could just get that nice axle "pin" out so I can get my front axle loose from the steering mechanism. I have used a puller (as a pusher) and a sledge hammer, afraid I'm going to break the cast iron it goes through, the pin and bushings are junk anyway.
