On a 39 1.5 ton
I removed the 5 lug nuts and the wheel, this left me with what looked like a spacer with six lug nuts holding it to the brake drum. I removed the 6 lug nuts. I could not get the spacer off by tapping it with a hammer. I thought maybe there was a spindle nut cover in the center of the spacer, but it wouldn't come off with a tap either.
My 47-54 shop manual does not seem to apply. any help is appreciated.
Thanks,

Scott | | | | | Joined: Oct 2003 Posts: 363 Member | | Member Joined: Oct 2003 Posts: 363 | Scott, does your 48 have this spacer like thing on it? What looks like the spindle nut cover has flats on it for a wrench or giant socket. Do I have to lock the drum up in some way to turn the spindle nut cover? | | | | | Joined: Jan 2005 Posts: 364 Shop Shark | | Shop Shark Joined: Jan 2005 Posts: 364 | 4.3, My '48 has the hub you describe as a spacer. It has 6 bolts that hold it to the drum? Do not remove those 6 bolts. Mine requires the removal of the spindle nut under the dust cap. You shouldn't have to lock up the drum, because the spindle is stationary. Just remove the nut,(check for a cotter pin through the spindle) and the hub should slide off. You might have to back off the brakes in order to get the drum to slide over the shoes.
That's how a '48 works, don't know how much help it will be on a '39?

If it were easy they'd have grade schoolers doing it!

Do you mean don't remove the 6 lug nuts that hold it to the drum? Is the 6to5 spacer removable? | | | | | Joined: Jan 2005 Posts: 364 Shop Shark | | Shop Shark Joined: Jan 2005 Posts: 364 | On mine the dust cover is held on by six 1/4in. bolts, sounds like the '39 must be a little different.
The spacer should be removable, but isn'nescesary to remove the drum.

I think the six lugs are press through the spacer, if anyone knows how to separate the spacer, let me now. I have an idea about a disc brake setup for stock big truck axles.
