Needle Bearing Tool Needed

Most of the parts I needed to finish the tranny for my 3A came in today. However I have to press in the replacement needle bearings in the cluster gears. It became quickly clear that if I try the methods that I have used in the past I would probably crush the expensive little rascals and produce much heartburn. In Nelson Riedels article he talks about turning a piece of aluminum rod so that the smallest part just fits the inside of the bearing and the next bigger diameter just fit inside the first and reverse gear shaft.
I have attached a picture of his device. Apologize for the quality of the picture, Its a picture of a copy of a picture. If you have made one of these jigs I would be willing to pay for the privlege of borrowing it, or buy it outright. OR if you have a better way to do it, I would appreciate hearing about alternatives.

Thanks, Tinkerman

As I recall, for those bearings I just found something that fit, like maybe a socket. Been a long time since I've done a crash box, tho; and the later ones are different, so perhaps I'm mistaken.

But I've made similar tools by using the drill press as a lathe, with a sharpened file as the lathe bit. Looked ugly (couldn't control the chatter) but was effective. Drilled and tapped the end, then put a headless bolt into it to grip with the drill press chuck.

If all else fails, Dick, PM me and we'll see if we can work something out. If you can supply dimensions, I can knock one out on the lathe in a few minutes. Of course, then it will likely take weeks for me to get it to the post office (No, I haven't forgotten about you Paul ... Tomorrow for sure! :G)
 
Oh yeah, here's a better copy of Nelson's photo
 
Randall,thanks for the offer! You mentioned using a socket, while taking a break from the honey do list, I rummaged around in my sockets and found that a 9/16 fits very nicely into the bearing (keep it in shape) and a 3/4 socket fit well over the top without impacting the ID of the shaft. So, in theory the problem has been solved! Couple of small details to be worked out but no biggies.

Thanks, Tinkerman

I did the same thing including using the inner shaft to help keep the needle bearing true to the cluster gear shaft as I tapped it in.
 
The socket set thingy worked like a champ, I'm happy to say. Ray I just bolted the whole thing together using washers as spacers in the 9/16 socket. I liberly greased everything involved also. Tapped it in with a ball peen hammer.

Thanks to all, Tinkerman
