On old Sevens evidence of a cold chisel having been used on some large nuts is not uncommon. It was not to gain special tightness etc but simply because tools were relatively very expensive and few had the range of large shifting spanners, special spanners, sockets etc necessary. Unfortunately many omitted to grind the chisel blunt first!

If there is any hint of indents in the expensive front bearings, these are ruined. If angular contact, normally otherwise reusable indefinitely with shims.
