remove the rocker arms

set engine to 'Lobes Down' and the crankshaft at TDC

remove the spring in the tensioner on the passenger side of the head.

mark the sprocket to the chain (for safe keeping).

Measure 180* around the sprocket and mark the corresponding tooth.

remove the sprocket from the cam.

flip the washer!!

spin the camshaft to meet the sprocket and line up the markers for TDC / lobes up.

replace the cam sprocket.

you should have only a very slight variance between the TDC readings on the cam and the TDC readings on the crank... Less than 6* of difference.

button up.
