I need to replace a badly worn JD7663R bearing. It looks like someone has replaced this bearing before by dropping the shaft out
the bottom, but didn't replace the washers under the eccentric gear on top. That led to a lot of vertical travel which beat the
hell out of the races on this bearing.
I've seen old discussions about this that include different brand bearings that will work; Fafnir 7209FT, new departure E30209A,
etc, but when I search for those numbers, Google always sends me back to those discussions. When I do a search for 7209FT,
Fafnir no. 7209B comes up. IT's only $30, the dimensions are identical, same type of bearing, but no explanation as to what the
difference is.
This tractor won't get worked like it was in the 50's, 60's and 70's, but I don't want to have a failure either. Have you gotten
away with using a cheaper bearing? Do you know the difference?
