Broken Casting

Postby goxu1 » Sun Jul 05, 2020 3:20 pm

Over the weekend I noticed a part of the casting on my cub was broken
Obviously been done for a while as its been painted over
Just wondering how hard it is to change this casting ?
Is the hole used to mount a drawbar ?

Which side is that? Or more specific, is that a front or rear implement hole? The housings are the same, left and right, so if you are only using the rear holes (for a drawbar, for example) and that is one of the rear holes, you CAN swap the housings, so that the bad hole is in the front.

Hi,
Your pic doesn't show if the broken hole is at the front or rear of the final drive.
The drawbar mounts on the 2 lower rear holes.
But, if you use a Cub 193 Plow, the drawbar has to mount on the 2 lower front holes.

It is some work to change the final drive.
Below is a post by Dale Finch, showing removing a final drive to repair the brake. It has lots of pics, you can see how to do it.
The Cub in the post has the 1st style of brake, which is different than your 1957 Cub would have.
The brake band, rod, and linkage at the final drive are different, but both are band brakes.

Whenever you remove a final drive, the oil seals near the brake should be replaced, so they don't leak oil onto the brake lining. There is another seal behind the brake drum, in the final drive housing also. :)

Hi,
The drawbar normally mounts on the rear holes to pull things at the rear of the tractor, so the front holes are not used, except for the plow, like I wrote above, or some other implements.

Below is a page from the 1955 Cub operator's manual, showing the drawbar.

It looks like the final drives have been changed to the opposite sides already, the Seed Plate Drive, is originally on the right side of a Cub. Yours is on the left side in your pic.
The left side originally has a cap over the end of the axle.
Look and see if the rounded cap is on the right side.

Below is a page showing the Seed Plate Drive, it is used to run planters.

If the rear holes are good, and the threads are good, it will work for using a drawbar at the rear. :)

OK , if the drawbar still works , it can stay as it is until it needs to be fixed.
Thanks for all the replies

Make sure if/when you install the drawbar that you use the tapered bolts, and they are the correct length (1"):

Heat the threads and hole with a torch to clean it, weld it up, with castiron arc rod then redrill it and face it off.

I had a local guy here rip out all the bolt threaded holes. I told him about the tapered bolts, he drilled and tapped them for a Ford 350 front spindle threads andvhe used the ford tapered nuts. I’m not sure if he welded up the holes and redrilled them first.
I'm technically misunderstood at times i guess its been this way my whole life so why should it change now.
