I would be fine with the bushing, it is only in motion when the clutch is open, should last a long time in a hobby machine.
The pilot bearing assembly in the flywheel, 1B3755 consists of a 1B3757 and the roller assembly 1B3756 which was used in the steering clutch of some later tractors and could be available.
The Hyatt numbers for the parts are:
1B3755, Hyatt #17059
1B3757, " #31262
1B3756 " #00531
And an old thread on the subject: http://www.acmoc.org/bb/archive/index.php/t-17223.html

Hi Steve,
I hadn't thought about that, the bearing is only active when the clutch is depressed. this tractor will never see the hard use it has had in it's younger days
Josh, thanks for those numbers The number on the outer race jives but the Hyatt number on my bearing is 7788. I'll go back to the bearing distributor with this new number and see where it leads
Thanks for the help.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
