I'm not sure if it would change how it floats. I will say that mine tends to bind up sometimes. It might be a good idea to Lube it up. Maybe some grease or dry graphite or something that won't collect dust.i looked at a parts breakdown. the bushing right below it is the same part. there is no way it could be out of round and fit the slot. i found one online and have ordered it. im kinda wondering if this may go back to some of the problems i was having learning to use the cutter, this unit may not have been floating correctly. i am sure it was like this new. sad that someone would put a part like this one a new unit.
