You could care less how you remove the old bearings.

The bearing puller shown is basic, but it also is all that is
needed to remove the old bearings.

Attempting to use the tool (bearing puller) to install the
new bearings is pure folly.

You will probably get the new bearings installed, but you are
almost guaranteed to brinnel the new bearings in the process
thus rendering them useless.

An arbor press exists for a reason.

I've had a set of these for about 5 yrs, used the small one once,
the neighbor
has used them a couple of times. They work great.

Here's a photo of a Unisaw arbor shaft with the bearing in place:

either ;-)

always nice to learn from other's mistakes...




You could also heat up the bearings by putting them on top of a radiator
and warm them up so they expand then drive them on.

They sell warming machines, but you don't have to buy one just use what
you have. if you can get them heated up to 140 You might be able to
drive them easily.
