The way I was able to repair mine was to drill out the dented area to get access the the back of the pin area. Care must be taken drilling straight down through the formed metal. Once through the outer piece, you must then drill or use an end mill to carefully clear out plug. You are then able to push the spring and pin out.
Before you can replace the old parts with the new ones you bought. You will have to have 3 new plugs with center nib made up and pressed back in and welded place. These plugs with the center nib are what your new spring must seat it's self on before loading the hollow push pin onto the spring and up into the hole before loading the dogs that actually grab onto the gear.
One small caution about your new replacement parts. I tried for over an hour to load the gear onto the clutch by pushing back the 3 dogs and was unable to do it. Just before giving up for the night, I decided to check the old dogs against the new ones. Pulled my 0 - 1 " mic out and the new dogs were .030" bigger than the old dogs. The old dogs looked good with no marks or damage of any kind. So I loaded the old dogs and tried the gear again. To my surprise, the gear fit in place and locked up in one direction and free wheeled in the other direction.
Hooray success. If you don't have the holes punched through like I did, you should be able to just use a drill or counter sink to remove the 3 pressed dimpled areas. The formed sheet metal would then slide off allowing you to do repairs as needed. Then just replace and weld the sheet back into the the 3 dimpled areas.
Sorry for the long winded explanation, but as parts become scarcer, the need for work arounds and rebuilds will become the norm. Feel free to PM me if you do have questions.
