Hole size with tolerance for Shaft

[moiz19670309]

I have a shaft with size dia 260.355
A Shaft sleeve fits over the shaft with rectangular key
The sleeve got damaged
Now we have to manufacture a new sleeve
I am confused what should be the sleeve ID with tolerance that I should give to my machinist. So that the sleeve easily fits on the shaft with locating key
Please help

You told us nothing about the application, the precision, the load, any maintenance issues, etc. Don't try to over engineer this thing. If your machinist is experienced, make sure he understands the situation and rely on his judgment. Young engineers can learn a lot from older, experienced machinists.
