It's actually not a bad job.... Take the motor off, then remove the 4 bolts that attach the stand.... Have someone help you turn it over onto sawhorses...
Remove the 3 bolts that hold the housing to the top... Remove the tilt adjusting wheel, and you'll have to jockey the housing it to get it around the shaft....
I set the pulley just so the end of the shaft was flush with the outside of the pulley.... You can fine tune the alignment from there using the motor mount slots...
A couple of years ago, the motor pulley came off and went inside the saw... So, we need to watch these things more closely in the future....
Sent to y'all offen' a iPad thing......
