reverse elec motor

Trying to reverse shaft rotation on 1hp elec single phase motor. I can read the schematic on the frame but not the numbers on the wires. Any help?

Their should be printed on the wires markings similar to what is on the schematic (on the motors I work with, the start
winding is marked T5 and T*, which you swap to reverse direction).

If nothing is marked, mark everything, and where it is connected,
disconnect everything, and test continuity of each wire to each other (using a DC continuity tester). Each run winding will have continuity to itself. The start winding will not have continuity, on account of the capacitor not conducting DC.

Can the motor wired for either 110 or 220?---Do you have "loose" leads or threaded terminals studs for the line connections?

Gary Tait's reply did it. Checked the resistance and found start winding wires, switched them and the motor changed directions. Thanks for the help.
