Unable to turn motor

[steplift20]

what you should do next is
1st pump grease into the fitting on the shaft[then try to move the motor] still dont move
2nd get out the tourch and heat the shaft and as your heating it rock the motor left and right until it breaks loose, it might take some time and also shoot some penertrating oil on the top of the shaft, what i did was install another grease fitting on the top cause no grease would ever come out from the top bot you have to be careful because when i turned the motor it hit the fitting but i had a flush mount fitting that i installed and everything worked out+
