Got the belt pulley inards out. Bearing question...

:lol: Sometimes I make myself laugh. I guess I've been working around avionics and mission electronics too many years. In that respect, giving something a good yank when it gets stuck can be a very bad thing. In the case of Farmalls, I need to set that thinking aside.

The pulley inards got a little stuck, so I didn't try to muscle them out. Well, after reading comments about using wood and a hammer, I said to myself: Am I applying enough a** to this? Nope. I gave it a good tug and it popped right out. :roll:

Ok, bearing question. I don't know what to look for in determining if a bearing set is good or bad. I rolled these bearings and they feel fine. What would bad bearings show, or feel like?

Thanks to the folks who answered my original pulley question.
 
You can tell the bearings are bad if you see any chipped or broken balls or rollers. Also if there is any rust or corrsionin the races or on the balls/rollers themselves it should be replaced. Another way to tell is if there is any resistance or friction when you spin the bearings in your hand than theres either damage or foriegn matter in the bearing. If the spin smoothly and freely they are good to go.

Sorry for long answer but hope this helps you.

I make long posts. I welcome long answers that have as much information as yours does. Thanks! Looks and feels like my bearings are up to par.
 
It was seaping oil, so I want to get that stopped before I refill the tranny. PTO and tranny seals are getting the same treatment. Possibly one of the brakes as well.
 
Use some carb or brake cleaner on the bearing. then spin it by hand llistening for any strange noises. There should be no roughness as it rotates. Re-oil the bearing to prevent rust.
 
With all due respect, bearing manufacturers caution against spinning a clean (no oil) bearing because fatigue points and chips can be created which grow under service.
 
Also, there should not be any noticeable side or radial play. There has to be some or the bearing would not work, but you don't want the inner moving around in relation to the outer race. The seal will never hold the oil in if it is.

Bearings vary in specification so there will be more or less play in a new bearing, but it is very little. Wash out a new bearing and see how it feels. If yours are much looser....
