ADDING GREASE TO SEALED BEARINGS

[grsr3]

OK---here's the final result. Received my grease gun from Chip (which I didn't need) with the special "tip" on it. Unscrewed the tip on put it on my gun which was already loaded with a grease cartridge. The tip worked beautifully, absolutely perfect. I am happy I waited for it before I brought the thing to be split.
The tip fit perfectly into the little hole on the outside cover of the bearing. I wasn't sure if it was really getting in there until I saw grease starting to come out of the edges of the bearing. I hand turned the bearing several times and greased again. Cleaned up excess grease as best I could. Started tractor and slowly by hand put pressure on the pedal. Beautiful---it spun free. The tractor shifted better than it ever did before---which tells me the **** thing was never adjusted right to begin with. No grinding like I would usually get. My PTO also shifts much better and pedal is firmer and more responsive.

NOW------the bearing DOES make a little noise and the pedal DOES vibrate some. I KNOW this is a sick bearing. But I am going to use it and keep my eye on it until it starts to really complain. That bearing ONLY gets used when you push the clutch pedal down (assuming the clutch is adjusted right). Time will tell. I will order a new bearing and fingers and have them ready for that day (hope I'm still here). George

Food for thought. You can over grease a bearing. To much grease will cause vibration and high heat. In industrial applications they actually use a ultrasonic monitor when they grease bearings. They only apply enough grease to the bearing to quiet it down, adding any more grease will start to cause the bearing to vibrate again. The additional grease also raises the operating temperature. I have seen many bearing failures in industrial plants over the years that failed because of to much grease. More is not alway's better.

If you're not in some hi-tec situation like most agricultural applications a bearing is'nt turning that fast so any kind of lubrication is better than a dry sealed bearing , Different if it is in a combine or forager and is running at high speeds but a sealed bearing is rareley fitted to a high speed application and on a disk harrow or wheel bearing it does'nt matter even if the seals are gone , if its full of grease it'll be ok just do it every day ?
