The spindle bearings on my Dyna 2400 mill are shot. Anybody done this repair and have any advice on a source for the angular contact bearings and best way to do this?

I was quoted A$200.00 for the bottom matched pair here in Australia. Fitting is straight forward. The collar with the 3 holes has no thread just presses out. Werner
I am looking for software for this machine to do engraving Can you help?

I hadn't run my Dyna 2400 for about a year. When i ran the spindle I heard noises coming from the spindle. I took apart the quill with the spindle in it and first reinstalled the upper pulley bearing assemble I ran it and it was quiet . Then I jury rigged the spindle and pulley belt and ran it. It too was quiet. So spindle bearings wasn't the noise maker. After further in investigation the nylon drive ring was part of the problem. The other part was that there was a little debris stuck to the belt in one place, After cleaning it up and installing a new nylon drive ring all was well. It ran quiet. I will also install a new drive belt. Those P$ super precision bearing are really expensive and am glad I didn't have to replace them.
