No pullers required and actually pretty easy, just kind of intimidating is all. Since the machine is new to you I'm going to assume there is nothing wrong with the machine other than 25 yr old clutch parts. Personally, I'd replace the primary and secondary springs. You might as well replace the helix buttons while you are inside the secondary, seeing as they are also probably 25 years old. Inspect the primary clutch weights for wear, same as the helix in the secondary. I'm sure that would make a huge improvement for you.
