Could someone tell me how long these bolts are. I have all 4 broken off and need to be drilled out. Thanks
 
If you hit water, you went too far.

Look at the bolt call-out (part number 110 500) under items 18 and 19:

Be sure you don't get a real sharp drill bit :oops: . No you can't ask what I mean by that :cry: :shock: , Pete
 
Sawmill,
Step 1: Carefully grind existing screws flush to the bolster.
Step 2: Carefully center punch the screws.
Step 3: Mark a #25 drill bit about 5/8" up from the tip by wrapping with a bright colored tape (i.e. masking tape or electrical tape).
Step 4: Carefully drill out the "offending" screw.
Step 5: Carefully chase the threads with a lubricated 10-24 tap using a manual tap holder. The left side (looking from drivers seat toward front) is easy. The right side is a challenge. The front screw is difficult. The rear screw can only be done with a long tap.
Take your time and you'll be fine.

After you drill out the screws, be careful with the tap. I know whereof I speak. I broke one off in the hole. No drill bit I tried could drill out that hardened steel. I finally got it out with a Dremel diamond dust covered tip. But then the hole was too big; so I threaded the hole for a quarter inch screw. Then I drilled the proper sized hole in the screw and threaded it. It worked, but you don't want to have to go through all that!

In my opinion, this has to be towards the top of the list of flawed designs of IH. Along with the teeth design of the throttle. I like the AC B design thicker steel all around the throttle assembly.

The main problem with the IH throttle teeth is people sliding them instead of pulling them out of the notches to move, then setting back in at the spot needed. I have worn out some myself before I learned that.
 
This is true, but should be expected that people would do the opposite, especially after many years of production. I would assume that the farmers had their complaints back then about it.
 
Remember the design life of the Cub was only 7 years. No one envisioned that they would be so viable 61 years later :!: :big say what:

Who knew huh :?: :?: :big smile:
