Dan,
I can remember for sure but, it seems to me, that you can pull the inertia weight along with the transfer bar by slipping the retaining clip off the safety switch and removing the safety assembly, then remove the "C" clip from the pin holding the clevis on to the fitting that attaches to the back of the frame, push the pin all the way up and slide the clevis off. You may have to hold the weight back and the transfer bar up.
