My CL360 has and endless cam chain as do all of the 360´s I believe (someone correct me if I´m wrong) on the front of the motor near the bottom you will find a bold and locknut, with the Number 1 Cylinder at top dead loosen the locknut and loosen the bolt... this will allow the auto adjuster to take up the slack in the chain, then tighten the bold and locknut, done.. to replace you will have to pull the top end apart, break your old chain, the new chain you get should be open then you can link them together and fish the new chain through your crank case, then remove old chain and rivet your new chain together, of course you will need a chain breaker/riveter and pin set, gaskets etc.
