 Topic: B Sealed Pilot Bearing
Posted: 02 Nov 2016 at 9:52am |
|
I have just completed the engine rebuild on my 1940 B and am realizing that the shop that reworked my crank removed the oil wick. I think I would like to use a sealed pilot bearing and plug the crank hole. Does anyone have a pilot bearing part number to do this?
Is there a direct replacement that doesnt involve machining the flywheel?

It's not going to happen! There is not enough room between the inside diameter and the outside diameter to put ball bearings in. The pilot bearing in your flywheel is actually a bushing. The only way would be to have the flywheel bored for a sealed bearing.

I just greased the stock bushing and reused it....not uncommon for old tractors and trucks........ The oil impregnated bushing sounds like a good idea.

Like them all, but love the "B"s.

This may sound dumb...I've heard of oil impregnated bushings before, but what are they? How do they work? Do you have to lube them?

Anyone have a source for oil impregnated bushings? I am having a hard time finding them.
Looks like I need a 1-1/8 od x 7/8 id x 1 length

For future reference, it looks like McMaster Part Number 6391K273 is what is needed for an oil impregnated bushing.
