[Farmall] H water pump pulley

[szabelsk at gdls.com]

It's called a Grooved Pin. The one that Farmall used on the pump for the H 
is 1/8 inch diameter by 1 inch long, Type A.  The part number is 142488. 
The concept in that the pin is slightly smaller than the hole it goes 
into, however the pin has been slightly enlarged at the grooved end. The 
groove allows the pin to be squeezed a little so that it fits snugly into 
the hole and stays in place. They're supposed to be great for vibration.

You can find info on them by doing a search on the internet using "GROOVED 
PIN".

Wow, wish I could see this thing. I can't recall ever seeing a pin of this 

type, anybody know the proper name for this type of pin? I'd love to 
figure 
out what it is and look it up in my machinist handbook.

Thanks for the help guys.

John

If they've got the pulley assembly off the pump, they can remove the
bearings, clean it up well, and drive that pin into the center hole of the
hub. Then the real fun begins  - the pulley and hub have probably been
together over 50 years and might not want to be separated...
