Im having trouble taking apart what I believe to be an Elgin 2.5 HP. The problem is in the gear case but I can't get at it. The gear case housing is jammed and from the top the leg of the motor will not separate from the lower gear case section. I know that on some of these motors there was a cap that could be removed to get at a screw but on this one there is no cap. At the bottom of the swivel tube their is a pin but the only way I can think of removing it is by drilling it out as it is flush on both sides of the motor. Any help world be great. Thanks<br /><br />Mike
