Brake/clutch pedal installation

We are trying to place the pin through the shaft collar on the end of the brake/clutch pedal shaft. The pin does not slide all the way through the hole. Is the only option drilling a hole through the opposite end of the collar? If we drill, the hole will be oblong on the opposite side.
 
I would either buy a new brake shaft collar or dill the old one out. If the hole is oblong the pin may still fit tight so that the collar does not move, or, if the collar moves a little bit it will not hurt anything. See https://www.snydersantiqueauto.com/product.htm?pid=979040&cat=41664

Is the hole in the shaft centered? It could be the fault of the shaft not the collar.

While you have the pedals out, add Zerk fitting if they do not already have them.
 
The collar pin hole may not be aligned on the center of the ID as it should be. The shaft may also have either misalignment or the end was damaged somehow that caused damage to the shape of the pin hole. A person could weld or braze the hole up on one side of the collar and redrill the collar using the shaft hole as a guide.
 
Unless the collar or the shaft are new, the pin had to have come out of there originally. I’d look further into this before welding and drilling. Of course, if one or the other are new, this doesn’t apply and the collar can be easily drilled using the shaft as a guide as suggested.

I agree with NK about adding grease fittings, fairly easy to do if the pedals are off. I drill and tap and use the 1/8-npt type. If you need to replace bushings a brake cylinder hone can be used to dial in the bushings rather than a reamer.
 
If you are not building a "show car", grind the end of the pin to slightly bevel the tip. It
need not be a sharp pencil point; just enough to ease the end of the pin's entrance into the collar's bottom hole. Once you feel the pin enter that hole, you can drive it the rest of the way home. The collar and the pin will be tight on the shaft and will not rotate. You will still be able to insert a cotter pin as long as you don't bevel the tip too much.

Best common sense solution I've heard in a long time. Good on you, Marshall!
