I was working on my brakes today - I need to replace the support plate (the pin is broke off) and the dust shield (broken pin caused cam to rip a wide, jagged hole in it)

I figured since I'm waiting for parts I might as well take the brake cam shaft out so I can strip/prime/paint it properly. I started looseing the nuts and bolts that hold the assembly together and once again, find that someone has been here before and monkeyed things up.

There are 6 bolts that I'm talking about - they correspond to holes in the support plate. The top and bottom holes had hex head bolts, which came from the axle side. They threaded into something inside the assembly, cause there was no nut on the backing plate. The bottom hole has another bolt on the plate side, but it's not threaded into anything - just sitting in the hole.

Three of the other four holes had flat studs in them (with splines under the head) the heads were on the support plate and lock washers and nuts on the axle side. The hole in the 10:00 position had a bolt and nut.

Looking at the NH Parts page, it looks like these are all supposed to be bolts, but it isn't clear in the picture what is supposed to go where.

I really want to post a picture of this mess. I've tried numerous time to upload photos to photobucket, but it never gets further than 0%. :twisted:
I'm also trying to figure out what seals and gaskets are supposed to be here. There is nothing on top of the support plate other than the hub, and it's leaking grease there. Is there supposed to be another seal here?

Thanks again Hobo. I think I got it now.
My engine is a 51, but the rectangular lift arms and bump in the tranny says those parts, at least, are from 52.
Whatever outer seal I have is leaking pretty good. Part of the problem was an overfull tranny, which I took care of already.

I just went out and looked again - the support plate doesn't show any sign of ever having the round retainer on it - I'll take that to mean that it never had one.
Thanks for your help and patience!

If the hub is loose on the axle you will never stop the leak,,, if the axle is loose from a bad bearing same deal

You should see the seal Behind the brake support plate you are replacing,,, it goes in the end of the bearing support

Thank you Hobo! The part in your picture with the yellow LH on it is what I'm missing - I believe its the outer seal?

The springs are practically new - the P.O. put new brake shoes on less than a year before I bought it. Of course, the practically new shoes are now junk because when the pin broke on the support plate it wedged the cobbeld "wing thingy" and the stub of the pin between the cam shaft and the shoes, which bent and severly gouged the half round pivot part of the shoes. I'll probably get new springs with the new shoes. I might try beating them back straight, but I dunno how well that will work.

One more question - the bolts at the 12:00 and 6:00 position - do they thread into something inside the assembly, or go all the way through and get nuts like the studs?

The 2 hex bolts at 12 and 6 o-clock on the rear retain the bearing support,,, if they did not the hole deal would fall off when servicing the outer seal...

"One more question - the bolts at the 12:00 and 6:00 position - do they thread into something inside the assembly, or go all the way through and get nuts like the studs?"

The outer bolts at 12/6

NO they do not go all the way through and get nuts like the studs?

Somewhere around late 51 or only 52's they did not have the seal retainer as seen in the pix,,, don't matter tho,,, you can use the seal retainer on either BUT not both the seal retainer and the seal made for a 52,,, confusing BUT use only one outer seal on either application

Me,,, if its a 51 and like the pix,,, use the seal and retainer,,, I think John Smith has a how 2 on his site

I also tried to remove the big axle nut today, and was turning both back axles (tractor is on jack stands). The tires spun wether the tractor was in gear or not. Am I missing something here? If the tractor is in gear, shouldn't the wheels be locked? The tractor ran fine when I parked it - just had the brake problem.

Her's a pix of what you should have,,, this is my own tractor sooooo ooo I used all the good used parts I had in my stash,,,, For the record if I were do'n a brake job on your tractor (customer pay) it would git NEW sprangs,,,, most of the brake problems I see here are (my bet) the sprangs are worn out and will not retract the shoes as they should,,, worst case the left side would git new hardware,,, Never will the left brake B as aggressive as the right brake,,, the left brake mechanism does not have the mechanical advantage the right brake has....

You can waist you time as you please,,,, keep in mind the sprangs are 50 years old,,, new hardware will perform as designed,,, on your tractor car or truck.....

If you need a better pix you can Zoom in on email me

The big axle nuts is supposed to be torqued at 450 Foot pounds. You need the wheel on and setting on the ground to get it off. Also to torque it back on. There are cap bolts at noon and six o'clock on both sides. The others are splined bolts that go all the way through and have nuts on the back side.
