Kelly,


A photo is attached.  The offset washer was used to activate the sensor and the flat one was the counterbalance.  With enough offset or mounting one on the front of the flexplate and the other on the rear of the damper, one sensor location could be used for two sensors giving 180 degrees crank angle difference for ignition purposes.

needed to activate the sensor.........a photo is worth a thousand words...........<:)

Joe,


When performing a dynamic balance of the engine and RD-1C, a CAS was mounted in the flexplate area as a position reference.  A washer with an extended portion was placed on one of the bolts holding the damper plate to the flexplate to activate the sensor.  A washer of equal weight without the extended portion was placed on the opposite bolt to maintain balance.  This required no modification of the original parts.
