Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I'm trying to remove the chain from my 1970 ariens snowblower. How do you do this? I can see that the connecting  link  retainer can be spread apart slightly , but I'm not sure if you push the pin thru while it's slightly spread apart or if you remove the link somehow.  Is the retainer reusable? At this point I'm using 2 screwdrivers to spread the retainer just slightly. It seems if you use only one screwdriver the retainer is not fully disengaged from the groove in the pin. Am I on the right path or is ther another technique.  Thanks Rich B.
