you can't just slide the cambelt off without removing the pulley first. you could just cut the belt, but that's a bit pointless cos you will still need to remove the pulley to get the belt back on later.
you will definitely need to remove the pulley to get the belt on regardless of if you can remove the belt with it still on.
i've done a few of these and i made a tool that holds the pulley in position while i remove the bolt, but you will need a welder if you what do do that. i used a bit of rectangular steel tube, with some small pieces of metal welded in a hexagon on it so that it holds the pulley in place when trying to turn the bolt. drill a hole through the middle of the bar so that you can get a socket onto the bolt.
having said all that i can't remember the reason why i didn't just chock the flywheel. you can normally get access to it by removing the starter motor, and i think the h22 has an access bung that provides access to the flywheel. it's normally not recommended cos there is a chance of breaking the crank if the pulley is really tight.
these engines have a balancer shaft that also has a belt on it that needs alignment
