Interested in this answer also.

 

There are two bearings back to back in it. I have the Pit Posse bearing tool, which I believe is essentially the same as the Jim's, and it removes and installs those bearings easily. There is no spacer between the bearings so you just seat one directly on top of the other.

 

 

 

I have the eBay install tool and removed the sprocket bearings with it. After my wheels and pulley were powder coated, I used the installer disk and tapped them in. I took my dremel with a sanding barrel to the inside of the pulley bearing surface first. Tight fit but they went in without an issue. Probably could have put the bearings in the freezer for a while first to aid in the install.

 

Some Brands of Tools have a "Receiving Cup" (Bridge) that are out on the edge (or slightly larger) than the Machined flat Area (silver).

Did the tool leave any marks in the Black area?

 

Mine did not. Are you worried about looks or damage. I assume you're talking about the part that has the forks/legs. Put some duct tape on the bottom of the legs. I was originally worried about it but then was like, nobody is ever going to see it if it makes a mark. Don't overthink it.

 

yeah, I got that ... I was just asking out of curiosity


And yes ghoulardo, use your "Installers" to eliminate the unthreaded portion

Btw, here's how you "pull in" your bearings without Tapping ... (using the 3/4" Installer in the "Receiving Cup" helps)
Although "driving in" the bearings "works" for this application ...

I am exactly doing this job right now. I was able to remove the top bearing, but the second or bottom bearing is so low that my George's tool is at it's max. The flat spot on the shaft is not visible. I did notice just before I quit, that the bottom of the expander has a 5/16 hex socket. So tomorrow, I was thinking that I could hold the expander using an allen wrench, and remove the second bearing. I will try this tomorrow.

I was reluctant to set the removal tool on the sprocket, so i took an old brake disc and set it on top of the sprocket. That is probably why my tool is just too short.
Does this make any sense? .
