Need sugestions on how to get the steeringwheel off my 8n. Have soaked in PB and tried every trick I know. Tried wiggling and pulling,tried beating with rubber hammer,tried blocks of wood and pinch bars,Thing will not budge. Was told not to use a puller on it that it could damage the spindle,only thing I haven,t tried is to heat it but didn't know if that could hurt anything. Anybody have any ideas?
