I have always found these to be a PITA to install. I have tried installing the rear bearings after freezing them and cant see any difference.
If expansion and contraction are proportional to the temperature then dry ice at -109 F should make a big difference. Used in combination of putting the 911 front hub in the oven at 250-300 degrees I am hoping the races will drop right in. Anyone tried it or have an easy method without the proper too size puller tools? |

Nothing beats getting them in smoothly than a little grease and use a threaded rod and nut / race adapter to pull them in slowly and straight . . the trick is starting them straight and flush before starting so there is no galling which occurs when they race walls are not parallel to the hub walls. Once you get a gouge and chip started it only gets worse.

The oven heat to 250 on the hubs and freezer on the bearing races made no difference. I pulled them in with the tool using the complete bearing and had them done quickly. Thanks to all who replied. |
