roll pin

[allredman 0]

on my c101 the collar at the bottom of the shife lever has a pin that holds the collar in place had broken and it moves around. after getting the set screw out that some had broke off. the pin looks like none i have seen. it looks like rolled up metal. i can not find one. my question is would a regular roll pin work and does the set screw extend into the collar to hold it in place. does someone know where i can get 1 or 2 of them. thanks so much. jim

the "rolled up piece of metal" you see could actually be a roll pin inside of another roll pin....drive the smaller one out first and then the bigger one....I've had a couple like this on some of the horses I have worked on in the past.

We have a privately owned auto parts store that has roll pins that are made like you are talking about but I dont think I have ever seen one smaller than maybe 1/4 inch in diameter.But the practice of doubling or tripling roll pins as mentioned inside one another is a very common practice.

I've welded a few of the collars to the shafts, just be carfull, not to get a weld on the rounded part.

The original 933168 roll or Spirol pin has been replaced by 32121-114 and is 5/32"x13/16".

The regular roll pin is normally called a split pin and these are the ones that sometimes get one or more drove inside to increase the strength.

If you do this, please be very careful to get the alignment right (use a screw or something through the hole to hold it while you weld). I owned a tractor that had a shaft welded like this and because it was a bit off caused wear. Eventually I replaced the shifter assembly but it was too late, the damage was done - if you did not shift with care the trans would jam.
