        Go here and get service manual.


        look at attached pic- note notches on cam ends pointing at each other and cam number markings- this is with crankshaft at TDC mark

          also, If you do have a 450 Try the Clymer manual from BassCliff's site. The Haynes is more for the 4valveperCyl 250,300,400s , not 2valvePerCyl 450s.

                  The "T" is the TDC mark - right under spring post. Staring at signal generator end, the crank spins clockwise- the "F" mark represents advance for ignition system. But reread manual or wait for 450 owner to chime in, as my 4 cylinder is different as to crankcase pointer.
                  When you count chain pins, remember that the one right over 2 mark is pin #1
