Heatingman 971 #1 Posted September 7, 2022 Ive read many times @peter lena talk of swapping out the grease in the needle bearing. Thats easy enough, but what about the ball bearing the PTO lever linage attaches to? Looks like a well fit rubber shield over the balls. Dont want to damage it trying to keep it going another 50 years. 1 Share this post Link to post Share on other sites
Jeff-C175 7,203 #2 Posted September 7, 2022 Those seals are generally quite easy to remove. Get a small screwdriver under the lip and gently lift it out. There's a thin metal shim as part of the seal, try not to bend it. Easily flattened if you do. 2 2 Share this post Link to post Share on other sites
squonk 42,534 #3 Posted September 7, 2022 Some of those bearings I've run across are steel shielded. Napa PP204RR6 $6.50. Almost not worth destroying the shields just to grease it 2 1 Share this post Link to post Share on other sites
peter lena 9,088 #4 Posted September 7, 2022 @Heatingman agree with @Jeff-C175 on the easy seal removal , use a flat pocket screwdriver , carefully get it started , once it starts , you are good . the existing generic lubrication , is the problem , in both related bearings , the inner needle bearing also , needs a wipe out , and a smaller amount of hi temp grease to prevent slinging onto clutch facing . lucas 560 deg , anti sling polyurea rated chassis grease , is the deal . BTW when ever I get ANY bearing , the first thing I look at is the side seal access , so I can easily , do the grease change / upgrade . EVERY RELATED BEARING , in my pto lever drive to mule drive to mower deck spindles has the grease change over , how easily do you think that set up works ? I don't continuously mention this upgrade , just to have an argument , but you know what fails , this is the fix, used it for years , my 3 horses have the same reliable upgrade , lots of hours , and silent bearings , you are right there in the opportunity stage , why not do it ? pete 1 1 Share this post Link to post Share on other sites

Almost not worth destroying the shields just to grease it I don't fool with them, at the price it ain't worth it. The only time I ever replaced those bearings is when I refaced the clutch surface. That size bearing is available in rubber or metal shields. 2 2 Share this post Link to post Share on other sites
Heatingman 971 #6 Posted September 7, 2022 (edited) Was able to add grease with a little dental type pick without removing the shield. Tried working the shield off, its just on there too good. Felt like it would tear, so I called it good. Edited September 7, 2022 by Heatingman 2 Share this post Link to post Share on other sites
kpinnc 13,730 #7 Posted September 9, 2022 This may bring out a few comments- but I usually remove the seal on the inside of the small bearing and leave it out. When I grease the large needle bearing, I push fresh grease into the smaller bearing as well. Just my opinion... Your results may vary. 1 Share this post Link to post Share on other sites

Won't centrifugal force spin the grease out of the bearing if you do that? 1 Share this post Link to post Share on other sites

I use a high temperature synthetic grease in the large needle bearing, I am sure that it is not compatible with what is in the sealed bearing. 1 Share this post Link to post Share on other sites

The rubber shield is not just a flat rubber over steel. This one is form fit rubber with an integral dust seal at the shaft point. 2 Share this post Link to post Share on other sites
