Chainsaw Repair

Can I buy the fly wheel puller that is talked about in my service manual still? and also the seal driver and oil pump tool? Or are there other ways to skin this cat ? we used to pull the flywheel by giving the loosend nut a sharp rap with a hammer while prying up on the on the underside of the flywheel.As far as setting the seals I would have most likely used a socket of proper size? but the oil pump,.....Never seen one dont have a clue.
