Replacing hub races 101
Not really a 101 project but what the heck....
On occasion you'll come across hub races that need replacing. Obtaining the races themselves can be an issue but if you happen to have one around here's the procedure.
Get everything ready. Its important to find a socket that the same diameter as the hub opening and race. Have this socket ready to go!!!
Pic 1. Obtain replacement race. I obtained mine from an donor Record hub.
Pic 2 & 3 . Install race removing tool. These are actually called 'bearing pullers'. I bough a complete set from Harbor Freight
Pic 4 & 5. Decide how your going to remove the race. You can either use a slide hammer or come in from the backside and tap the puller (I guess at this point it a pusher) with a drift (I used an axle) and hammer
Pic 6. Heat hub shell. It doesnt take much, 3 or 4 seconds is all.
At this point remove the race with the desired mothed as seen in pics 3 or 4. Let race cool completely before removing race from bad hub. This is important as you want to shrink back down to ease installation.
Now you remove the bad race. Follow the same steps as you did when removing the donor race. As soon as the bad race is removed immediatly install the donor race. My donor race dropped right in because it was cold and the hub shell was still hot from removing the bad race. As the hub shell cools it tighten around the cold donor race. If the race doesnt drop right in heat the shell a touch more and drive it into the place the socket.
