    rotary valve timing

    Hi is there any way of timing the rotary valve on a 787 without the degree wheel ? If so how ? Thanks

    there is an index pointer on the crankcase that the edge of the rotary valve needs to align up with, when the mag piston is top dead center..

    The process is outlined in the service manual.. If you do not have one, you can download one here www.seadoomanuals.net
