Probably would have been easier using a spare clutch drum during the install. I simply don't know as I have only seen one Dolmar saw in 14 yrs.
It is like resetting the Husqvarna chain brake on some models where the customer have pulled the cover off without setting the brake. I had my machinist to make me a tool that I use with a pull bar as I simply can't not reset these things without it. I designed it and he made it. Too bad I got to find myself another machinist as he is retired now.
Either way these brake springs are a pain to install. Spring rate is very high.
