I use a 10" impact extension with my snap-on gun.It only take a quick tap to knock it loose.before doing that get a few cans of brake clean and scrape as much of the poo off the area and then clean it all up and then spray it spotless clean before you remove the recoil pulley.this way no dirt will gone in when you remove the seal.it's somewhat of a pain to get in there to change it but it can be done.the last one i did i had done it while i had the swingarm off because it was ALOT easier.
when tightening the bolt back up don't hold the gun on it hammering away.just give it a few taps to lock it down.
