most motors have two red plugs or brown plugs either side of the motor , usually 4 philips scews on undersid to undo and remove old bushes and renew same way, either way the motor has to be removed from machine first , easy jof if you remove the back cover and lay machine face down on a cushion UNPLUG first
good luck, ps might be better to get a second hand motor for a fiver like i did from your local breakers yard , but try to get the same model or make
