I just used a Jims tool to pull the INA caged bearing out of my 77 FX lower end. No scuffs in the journal, looked fine. I set up the cases on my press and the new B-138 Koyo went in with about ZERO effort or force. It is not tight at all....bought another one...same thing. I've pressed in about 200 ironhead torringtons and they are never went in without resistance...how tight do these fit in shovels??? I do not have another set of cases to measure the journal but I think it is about a .004 tight press fit. I have no experience with shovels so the "feel" of the fit is new to me.

Should have left that damn INA alone.....

 

the INA could have and might have taken the lower unit out --

the shovel is not as tight as the iron head - if you are stressing about the light fit

you could use a dab of red lock tite -

in extream cases a sharp pick to peck the the surface almost like knurling the surface of a shaft < but that is in the extream - put a few drops on red on it and forget it

 

okay, thanks. I just do not have experience with shovels so hearing that the B138 might not be real tight is good enough for me.....I'll finish this thing up and forget about it
