Tilt shaft broke on the end at the hammer blow coupling. coupling is fine got replacement shaft I can't figure how to get the old one out.I took the motor out and I removed clutch pack, I still can't get to it because the big gear that is driven by the worm gear won't come out. I took the C clip off the cover on the intermediate housing at the end of the shaft but that cover didn't budge either. Anyone got any ideas?
