howdy everyone!!
today we're swapping out the spindle bearings in the Grizzly G7945 drill press. chinese bearings are baaaad, very, very bad and so i got ahold of some SKF bearings to upgrade the machine.
some of the bolts and screws have been swapped in the assembly process and so we are skipping that portion of the upgrade. unfortunately the belt pulley spindle bearing are on so tight that taking them off without a press or a proper fitting mandrel would damage the spindle beyond repair. so until i can get access to a proper press, they will just have to do. since they don't contribute to the accuracy of the chuck, they can stay in the machine until they fail.
Grizzly has a great tech data base on their machines and so i was able to identify all the parts and their respective sizes before tackling this project and had the parts on hand before getting started
