First I would not just go with a bearing because that was what they had in it before.
First I would want to know what the crank was made of, because that determines what the bearing should be made of too.
And I have seen guys put the wrong bearing in things. Don Garlitts told me that.
Rule of thumb Steel crank, steel bearing, not the tri metal bearings.
Soft bearings on a soft crank or they bite in to each other and you'll spin a bearing,
it might last a while, but it will happen.
