PTO roller bearing removal

[Jeff-C175 7,202]

I just finished replacing the roller and ball bearings on the PTO bell for my 'new to me' C-125.

 

None of my pullers were able to reach inside and grab a hold of the roller bearing.  I ended up using a punch and went round and round until I got it out.  I was as careful as possible not to knacker up the bore but I did have to clean it up afterward to get the nicks out.

 

The tools that I have made easy work of reinstalling the two bearings.

 

What is the 'correct' tool to use for getting the old roller bearing out?

 

I'm thinking a 'Pilot Bearing Puller' would do the job?

Like you, I had to 'improvise' the removal of the old bearing.  CAUTION... when installing the NEW bearing, DON'T seat it in too deep in the PTO bell.  If you do, the bell won't uniformly ride on the bearing race.  The new bearing should be installed just far enough to get the NEW seal seated inside the rim of the PTO bell...no further.

I measured the depth before I removed the old one.

 

Upon removing the old one I discovered that there's a 'land' inside there and you can't install it too deep.

 

Did yours not have the land?

I might have a good puller for that, I will send you a picture as soon as I can.

I used it as well to remove tranny bearings. 

 

EDIT:

here it is; We have them in difference sizes. Look how little is left of that bearing and still managed to pull it out.

I just did one and it could be installed only about 1/8" deeper than necessary, so not an issue.

 

There was a pair of notches behind the bearing to punch it out, I just used a brass punch and hammered the old one out by alternating notches.

I ,spect those notches are intended for removal of the ball bearing, but that's what I did also.  That roller bearing is a tight fit!  If I used a brass punch there wouldn't be much left of it!  I 'modified' the tip of a steel punch with a slight angle so it didn't slip off quite as easily.

 

I have an antique wheel bearing race installer that worked perfectly for reinstalling it.

 

Had that not worked I would have had to go to my friends house and use his press.

 

I would never, ever install a roller bearing such as this with a hammer and drift.  You would ruin the bearing for sure!

That's a type of pilot bearing puller I think.

 

What's the bottom look like?  Does it somehow expand to grab the bottom of the bearing?

100% correct, by turning the lower nut, the underside expands to your need and then you but on the rest and turn the top nut to pull the assembly up.

I punched out the small bearing first by using a punch on the center since it was going to be replaced anyway.  The notches can then be used to punch out the roller bearing, mine was not hard to move.

 

To install the bearings, I used a stud, washers and clamps from a milling machine set like this:

I had washers and spacers to draw the bearings in to the final position.

Here is how I do it.
