Regardless of which motor and transmission I swap into this machine ( 2 different good used transmissions and 3 different good used motors ) this 10yr WP will draw 12 ton13 amps when agitating with large load. Tub and basket clean and nothing jamming them, basket tube to shaft clean and lubed, and waterpump clear.
During spin cycle motor draws 8 to 9 amps with same load of clothes.
Also, if these motors are thermally protected, at what temp should it trip?
Each of these motors get too hot to touch, yet still keep running at 12 amps. There is no smell of electrical motor failure. And this process has been done outside with cabinet removed and ambient temp is 65 degrees.
Do these motors have a "service factor" amp draw? If so its not stated on motor along with their rating.
Perhaps I'm not getting a good connection to motor during agitation?? If so I m thinking of bypassing timer and wire harnest to motor switch,,,,but which wire combinations should I send a direct power source to for not hi and lo agitations?
Any help or thoughts is appreciated.

For high speed on a 2-speed motor connect hot to motor blue wire and yellow wire. Connect neutral to motor white and capacitor. Remove red wire coming from timer from capacitor and connect there (to the capacitor). For low speed, hot to motor orange and yellow.

I don't know the trip temp rating for the thermal overload but the motor is rated for max ambient surrounding air temp of 40°C (104°F) and winding insulation rating of 130°C (266°F). The thermal switch is mounted on the frame right next to the motor switch.
