It's a metal tap somekind, but how long? If i make new like cutting a drill bit?

I don’t have one apart anymore to measure it. I will look in my book to see if it has a measurement I’m thinking you’ve lost your oil pump drive pin. The washer will have part it rides in will have a cut out for it you don’t want it super tight but you don’t want it to disengage either.

Thanks Honky Kong jr! I think i can make one.
Merry Xmas all!
