« Part 4: Cutterhead Cleaning Part 5 of Jet JJ-6CSX series Part 6: Long Time Coming but it's cutting nice and square! »

Having obtained new bearings, I am now faced with how to reinstall without a shop press. Even before I could use it, I would have to come up with some type of sleeve that would only press on the inner ring and not on the shields. How about a 1/2” impact socket? . So if it’s an “Impact Socket”, why not try to “Impact” it into place?

A little grease to ease the installation.

Place the bearing on the shaft.

1/2” Drive Impact Socket


Rinse & Repeat

A millwright showed me a little secret to putting bearings on shafts, this was in the middle of one of Montana’s
mild winters, only about minus 10 degrees. He put the big electric motor armature outside to cool off at the
beginning of the shift, the cold shrunk the metal shaft, then he put the bearing on a hot plate, it had metal
dust shields on it, do not do this with plastic dust shields. When the bearing was very warm, not hot enough
to hurt the grease, he used a heavy pair of welding gloves and slid it onto the shaft with no trouble. You
can substitute your freezer and the hot sun with the same result.
