We had not planned on using the brake on the motor. In fact, I didn't know it had a brake on it. Does that brake have to be disabled? How do we go about doing that? We had simply planned on using the motor to drive our swing arm. Is there another motor that would be stronger/better to use?

<R85> allows you to remove the pin but you are not allowed to "file, machine or abrasively remove any part of an air cylinder".

So you cannot enlarge or machine for a key. You can bush if the original hole is larger than the motor shaft. You cannot machine the hole larger if it is too small. Pressing the cylinder onto the shaft 'as is' could fall under the "abrasively remove" clause.

Make a mounting bracket to fit onto the pin then have a larger hole.
