Back to square one

I have given the rear end a good inspection. K9 128-40-HD casting number. I have pulled one hub, and I need some new shoes. I am also missing one axle spacer. I have a really fine crack in the pumpkin, but that's a pretty easy weld. What year is it. I have searched for topics on this board, but came up empty. I think there will be some photos, and questions to follow, as long as I can get pics on the computer. I will try tonight, but right now I'm watching the Hurricane, make a B line towards some family.

Re: Back to square one

Thanks, My oldest son is in Jackson, MS. I called him last night and he was at a friends house. I told him to get home and stay home. He's 15. Immortal still.

I plan to post some pictures later tonight. I have a new camera, so I need to install the program on the PC. What do the casting numbers mean? I am figuring that it was made in 40. Am I right on this? I have to get some studs to pull off the other hub. I had a few yesterday, but every one I tried would not thread, so did not force the issue. I'll find the right thread, and pull it Wednesday. The hub I removed has another hub for car wheels, welded to it, so I used my gear puller on that.

The good news, is that other than brake shoes, I am in good shape so far. The only thing I am missing is an axle spacer. I can make one of those. I am going to strip the paint off of the pumpkin, so the aluminum finish shows. I need to weld the crack, and I think a good polishing will be in order. When I was dreaming last night, I was making plans for it. I had the coolest dream! Now if I can put my mental notes on paper, I'll be fine!

Re: Back to square one

K=December 9=49,59,69. Obviously there were no juice brakes in 49 so that rules that one out. That leaves us with 59 and 69 and as far as I know there is no major difference between them. Being made in December that are the following year model. So you either have a 60 or 70 rearend.

Re: Back to square one

This unit is mechanical, so it's a 49. I appreciate it. But why is there a 128 40 HD What does that mean?

What bolt thread will screw into this hub, so I can pull it off? There are five of them, I guess they were lugs.

That is the factory casting number. It show this part went into production in 1940.

Re: Back to square one

Cool! Thanks again. Do you know anything about what thread pattern the bolts to fit the hub would be?

Like everything else on a Harley they are a bastard thread size. 3/8-20.
How did you wind up with half of a hub?

Re: Back to square one

Well, I'm just lucky like that. On the other hub an adapter was welded, and if you look closely you can see where one was removed from the hub in the picture. I'm just trying to look at the brakes, as I am hoping that will be all I really need to rebuild.

Re: Back to square one

Yeah, My boy is fine, but still dodging tornados. I'll be making some bolts to pull the second hub today. I called around yesterday to find some, but when i arrived they said, Oh! We only have 3/8 24's. So Three parts houses later.........I get the pleasure, of doing what I should have done in the first place.

Re: Back to square one

1. Okay folks, I need opinions please. My second drum is pulled, and as the other I am missing a break lining. No big deal. As, stated before, I really believe this to be the only problem I have. On the other hand, You never truly know until you get in there. My housing is cracked, so would you repair from the outside, and hope for the best, or just dive in, disassemble, and reassemble?
2. Are the grease alamites gonna be a bastard thread as well? I played hell getting the bolts to pull the drum, so if I can't find replacements, I'll just re tap for newer standards. No big one there either.
3. Please share with me any information. from experience, any problems that I may encounter, special tools, etc.

Re: Back to square one

Hey Bro. Pretty sure the grease fittings are 5/16"-32 UNEF straight thread. Can you post a clear photo of the crack and add dimensions of it ? The skilled welders on here could advise you best with that information. Oh yeah, the taps are available from several vendors. Kurt has them. Harbor Vintage has them. Most machine tool supply companies have them also. Pa
