How do I grease a bearing without grease zerts.

I doing more repairs to my old Allis-Chalmers rake and greasing. Looking at the bearing I see no way to grease them there are no grease zerts. I was thinking of taking the bearings lose to grease, but the bolts are on very tight. So do I hope they never wear out?

I learned something new sealed bearings, these must be sealed bearing. They move and sound good so I guess they will last another 60 years.

Thanks

life is about over, time for new ones.
 
They are sealed bearings that are greased for life but they don't say whose life. From the picture I would say they are still good. Occasionally I have extended the life of a sealed bearing that looks as if it has reached it's best before date by coating the outside with grease. I also have an adaptor for a grease gun that looks like a hypodermic needle with a grease nipple on one end. I snap the grease nipple onto the grease gun and then push the needle through the rubber seal of the bearing and pump grease into the bearing.
 
These bearings move easy, so how long do you think they will last? The rake is an oldie, but goody I think made in the 1940’s. Do you think these bearing will last 40 years? If you view the full picture you will see we have done some welding on the pulley hub, also we replace a cable? I suppose like people a little “TLC” and you last a little longer.

THANKS





 
I have this idea:

“Make all in power over others, live with a farmer for a year, repair machines and learn how to ask for help from fellow farmers to understand cooperation, and a real since of what is truth”.

Walk a mile in another ones shoes before you try stepping on their toes.

Thanks to all who help.




 
Shealray,

Liquid grease spray will work it's way out as easily as it worked it's way in unless you apply it regularly. Plan to remove the bearings. You can repack them again by hand. I've done many of them by popping out the seals using a seal pick. This can be done without damaging the seal so it can be reused. Many of these bearings still contain a small amount of grease so clean them well. After cleaning check by feeling for abnormal bearing surfaces and sound. If all is well you will get a lot more life from them.

That rake is much newer than the 40s. AC had the pto side delivery rake before they made this one, a parallel bar style. The Model 77 style was first introduced in 1958, and the Model 78 made from 1965-70. 78 had the sealed bearings, don't know about the 77.
 
Bearing 101
Got any pictures of a bearing pic and how to use it? We have and impact wrench hoping after socking with blast this will help loosed the nut holding the bearing on. By the time we do all this it is about like rebuilding the rake. The rake works well with my ford 850 tractor and I can turn both directions in a very tight turn.
Thanks for the information.

Its a very inferior hay rake, hardly worth scrap price, but if you
deliver it to me, I'd go $12/cwt, for it! Now that there is some
bigtime sarcasm, right there!
 

I file the Needle to a much sharper angle and narrow it all I can and it usually will slip under the edge of the seal, to inject grease..
Sometimes, even New bearings can hold a lot more grease than is in them from the supplier..
I think it is worth doing..

There is areason for some "room" in the bearing. Maybe not in the case of a hay rake, but I have seen bearings overheat and cause real problems when too much grease is added. The manufacturer has WAY more expertise in this than the farmer mechanic.
 

Oh sure...!!

Mass-Produced parts are seldom what they should be and if behoves the "Farmer Mechanic" to be SURE the new parts and/or Bearings are ready for extended service.
I bought a Ryobi Limber and found the grease was "IN" the bevel gear compartments but NONE was "ON" either gear..!!
Why would anyone think a "Farmer Mechanic" could not be an Aircraft Mechanic at the same time..??

Farmers have to be everything from medical to mechanical the back bone of how this great nation started. The willingness to say “Sure Why Not I will give it a try" is what set’s you apart from others. “Do not judge a book by its cover”, or be fooled into thinking those who ask questions are simple minded and have no skills. The best teacher is learning from others. Keep on teaching those who ask no matter how simple the question is to you. Your answers have value passing on knowledge which is lost to new generations. This forum works well when all pull together to help. Thank you all for the help.




 
The rake serves me well and will for many years to come. Remember “One person’s trash is another person’s treasure". Thanks but no thanks I will keep the rake
