Here’s what was just removed. (from left to right)
Nylon bushing, steel insert/bushing, counterweight, and bolt.
Parts are shown in appropriate installation/removal order.
I broke the bolt loose with a 3/8 ratchet, and then used a 1/4 ratchet to get it the rest of the way out.
Space is at a premium in this location. Not much room for your hands.
I also reinstalled the bushings and bolt, cause I just don’t like leaving holes in the transmission.
And, if I ever decide to put the counterweight back on, all the attaching hardware will still be ready to go.
