620 reduction gear cover shaft

farmerjim72 · Feb 21, 2021

Finally got the crank back for my dads 620 and we are putting
it back together wondering is there a torque spec for the nut
on the shaft that comes threw the reduction gear cover.
Wondering if some one can help or is it just snug it up and
back it off that the cotterpin fits threw?

Good and tight without backing off preferably

I don't know the 620 personally but I'll share a tip I was given years ago for castle nuts, when you want to have them tight and not really back off. Tighten it and if the pin lines up, you're good, if it needs to go a little more to line up, but you don't want to strip anything, file the backside of the nut a little bit, try it, and repeat as necessary until it lines up at a torque you're comfortable with
