very carefully. =-)
i use a little brass hammer and work my way around the race one rap at a time. also i taper the hub ever so slightyly with a fine file to allow the race to enter the hub a little more easily. make sure everything is squeaky clean. put the race in the freezer for 30 minutes beforehand. |

do you have access to a bench grinder?
if so, grind down the OD of your old races and use those to help press in the new ones....also, the largest diameter socket you have helps as well... freezing the new race and heating up the hub works as well |

So it's a light press fit I guess. I just want to do it right the first time.

It is tight. don't fool yourself you will need a hammer if u don't have a press. Use the old race and grind down the outside. flip it over so you have more to wack and don't stop until it is seated. If you don't have a grinder use a large socket. I froze my race and it still needed some hammer blows to get it in. Good luck.

Yup. Put the races in the freezer the night before, and tap them in gently using the old race between the hammer and the race. I try to not take the race out of the freezer until just before I'm going to put them in. I've never been lucky enough to have them drop in, but I've also never tried heating the hub.
Also, clean, clean, clean. Get all the old grease out, and don't pile in a ton more. Roller bearings don't need much lubrication, so just pack some into the cage and leave it at that. I've pulled apart hubs that literally had over a pound of grease shoved into them, to no good end. Also fit new seals, and lightly grease the lip of the seal... |
