Replaced speed control and saw was still running backwards.
So next replaced field coil and saw now works properly.
I have model with gravity stand and to make repair I left saw in folded position which allows view of underside of table saw. 1. have new field coil present before starting repair to make referencing easier. 2. s

Next remove long black wire that goes to brush housing on right side. It is conjoined with red wire coming from field coil still in side housing. 8. Un plug both red wires. 9. Remove 4 phillips screws from motor housing at base and slide off housing from armature . The bearing will stay with armature , field coil is in housing. 10. Remove two long machine screws that hold field coil to housing, then use long flat blade screwdriver and gently tap field coil out of housing ( carefully go from side to side against solid part of field coil. You can suspend housing across 2 blocks of wood so coil has room to come out. 11. Now replace new field coil matching orientation of old one ( because of tight fit use a little dish soap on sides of field coil and make sure to align with threaded inserts in head of housing. Make sure to pull wires from field coil up through housing before completely seating field coil. 12. Replace 2 machine screws and reattach wires.( I reused wire crimps but it would be best to use new ones)
13. Reattach top housing and then attach complete motor housing to armature. replace table saw stand lever and rod assembly. Done

Speed was up & down, then when running the motor sparked
1) Replaced speed control - motor still sparked & ran poorly
2) Ordered field, armature, brushes & bearing
3) Disassembled motor, armature is pressed in, so either use puller or remove gear cover opposite the motor shaft & gently tap it out.
4) Inserted new armature, gently tapping it into pressed bearing (wood in betwee

5) Replaced field, soldered all wire connections & taped as the crimp nuts take too much space in the confines of the motor cover
6) Replaced with new brushes - old ones probably still OK.
7) Runs like a champ.
Very simple just opened up the motor and replaced the speed control closed the motor back up reinstall the housing and flip the switch. Not Very difficult if you have some common sense
Took off motor housing, marked wires to make sure they were replaced in correct order. Had to remove wire grommet that held the wires in the housing. Replaced controller. Put back together.
Remove the small cover on the end of the motor where the wires go in clip the wires replace the speed control reconnect the wires and replace the cover
Place table saw on its side. Take a minute and use compressed air to blow all dust from around the motor. Position saw/ blade in position to allow the easiest access to the rear of motor. Remove three screws in motor cover plate. This allows access to speed control. Speed control has three wire. Two wires are crimped on and the other alr

After pulling old speed controller out and replacing with new, reattach wires with two new wire connectors (not provided). When reattaching the motor cover plate, make sure all wires are positioned to allow the cover to be reinstalled without pinching and/or damaging the wires. Tighten the three screws holding the cover plate. Check work to make sure everything is tight. Check and make sure table saw starts and operates normally. Good luck!
Unplugged the saw. Tilted the motor to 45 degrees. Removed 3 screws to remove the cover off the motor. Cut one of the wires going to speed controller, removed one wire nut and unplugged third wire from the motor. Replaced the speed controller. reconnected the wires. replaced the motor cover.
