Pilot bearing or bushing???

[TEX29]

I am about to embark on an endless journey. In search of a destroyed flywheel starter ring gear on my '40 DeLuxe. In preparation I already had my machinist surface and install nos ring gear on an extra flywheel.

So what do you guys think I should install a newer rollerball bearing or a nos bronze bushing? I have both on hand. Let me know your thoughts and experiences. Thanks Ford Barn

I like the original style ball bearing. You can get a sealed one that will never need to be lubed. A bushing is OK but they can dry out and wear. That all being said I'm sure there may be others who prefer a bushing.

If you use a bronze bushing, just do not lube it with never seize compound! Saw that done once. Bushing destroyed in no time.

A sealed bearing should last forever, it only "works" when you shift,,,,

If your shaft is in good condition the bushing works fine, any signs of pitting rust or nicks that will wear the bushing out fast go for a bearing.
The bearing likes to stick to the shaft and is a pain when you need to remove the gearbox later.

just make sure you use a quality ball bearing.

The shelf life on most grease is about 4-years so sealed bearings don't last forever. The pilot bushing or bearing should be replaced anytime you have the flywheel out for service. Either one will provide good service if you follow that plan.
