need a final drive identification number

[boldpsi]

i have to replace my right-side final drive (see post for "broken implement bolt holes"), and JP Salvage has returned my email. however, they've asked for the "350..." number off the final. thare ain't no sech numba! see below:



from the pictures i've seen elsewhere on the forum and 'Net, it should appear in the upper right-hand side of this picure (or final, for that matter)... am i confused, or is this just a little test of the forum's brain-trust?! let me know if y'all have any ideas on how to identify this part for the boys at JP Salvage (or anyone else for that matter!).
thanks!

Since you have a late model cub it will be the housing for the toggle style brakes. You might try looking on the left side final drive casting and see if the part number is on that one.

Maybe this will help you?




There were changes on them, hence the suffix at the bottom of the second page that refer's to the SN's?

I have two 1949 cubs and the number on all the final drive housing is 350806 with a R2 below the number. The number is located above the IH on the right side of the photo you have shown. Your's does not have the number where mine are located.

Hope this helps.

Big Dog hit the nail on the head (as usual).

Just look for a toggle-style and you would be all set. No left-right issue. they are all the same.

Probably the only fussy detail you could get into is a casting date to have one that matched your original, but that is not a functional issue and the chances of matching a casting date for this year of limited production is ultra-slim. The casting code on my old ones that I replaced was a plate held on by screws on the left side when facing from the transmission and as Jim said the number is cast into the right side from the same view. But this is non-toggle.
My toggle finals on my 74 don't have either just an "8 8 X" cast into the left inside view. This could be a casting date code as it is not uncommon to attach a date code number plate to the mold so the lot number is cast in. It is less work down the line so someone does not have to screw on an ID plate.

In my opinion, potential confusion arises from posting any number other than the exact one for the application. Earlier it was twice mentioned that the housing must be for the later style brakes. Any of these Cub parts sellers should be able to work with just that information. The TC-37F catalog lists 350 806 R51 as the housing required.

Thanks for the astute observations! i didn't know that all they needed to know was "they're toggle-style brakes", buy i will.

also, the number on the left side of the photo is "11 27 B", which i guess is the casting date of Nov 27 in some year which went from A to Z, then back to A again, etc., and probably represents 1978 in my case...

additionally, there are what looks like 2 little plates attached with screws in the spot that the "350...R..." number would be, but i don't understand or know their function...

but i'll contact them and let'em know... thanks for all your help!

The 11 27 B indicates a casting date of Nov 27, 1978. What appears to be plates attached with screws is just part of the casting and it is where the part number should be. Have you checked the casting on the other side to see if the part number is on it? It appears that the part number just never got stamped into this piece.

Folks:

i just spoke with John at JP Salvage; he indicates that even on Toggle-Style brake-final drives, there's an R#. mine seems to have had a bad casting experience, in his opinion. he says that with a 1979 IHCub tractor, that means an "R8"...

so, i guess that's what i'm ordering!

the next question is: as a mediocre mechanic with some pretty good tools, how the heck to i do this job?!?! i guess i'm hoping for some directions to other posts or 'Net pages which i can learn from and use as a guide to doing this. i suppose the first thing i need is a taller jack and some taller jack-stands! i guess there's an IH part specifically designed for these tractors? any help above and beyond what you've already done will be graciously received...
thanks, again!

Dave, as BD said:

Check the other one for the part number suffix, odd's are that one will be there.

[boldpsi]

yep, i did check it, but forgot to tell y'all... it's just like the right-side, with the funny screwed-on blank plate looking thingys... oh, well!

Dave,
If you have a trailer and can wait until CubFest Northeast 10/19-20-21 in Kinderhook at Cecil's place, I'm sure we could have the final changed out in no time. There are some seals and gaskets that you probably should get. I'll let the pros chime in on that item.
Oh yea, whenever you jack the rear end of a Cub - WEDGE BLOCK the front axle.

boldpsi,

You're only about 2.5 hours from Cubfest Northeast on 19, 20 & 21 October in Kinderhook, NY. Give some thought to loading up your Cub and replacement final and coming for the weekend. Even if you can't bring the Cub, come anyway. You'll have a great time and learn a few things, to boot.

Hope to see you there.

To add just a bit to this comment. Whenever looking in the Parts Catalog, never use a catalog edition that is older than the tractor. The pages shown above are from TC-37A (1949). The correct final drive housing for a '79 Cub isn't in that catalog.

[Bus Driver]

Since the present plan is to change the housing, I suggest saving the old one if storage space permits. Newer repair techniques may appear, the owner may later acquire new tools and skills. Repairing that housing is not at all out of the question. And the broken one has the "correct" casting date code.
Catalog TC-37F was issued 8/79. As far as I know, it is the latest print edition that exists. I do know that some part numbers have changed since then and some have been deleted. The dealer has always found the numbers that I presented from the TC-37F to be useful and has found later information, if any, by virtue of those part numbers.
The newer brakes were introduced during the 1953 model year. My assumption has been that any housing originally used for the toggle brakes could be substituted on any tractor that was so originally equipped. If this assumption is incorrect, it would be helpful to know.
Obviously the Lo-Boy housing is different and not interchangeable.
