AMC360 Damper 36-1 Template 'tooth A' @ 40 DBTC

thingiverse

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/6lCV4Fa4oa6 This is a template for drilling an AMC V8 crankshaft damper for use as a crankshaft position sensor reluctor ring. This was used for converting an AMC 360 to wasted spark ignition after it was first converted to throttle body fuel injection using a megasquirt II engine control, although the reluctor may also be used on other engine management systems as it is designed to mimic a common '36-1' trigger wheel pattern. In this application, a sensor is mounted below the fuel pump mounting boss which is no longer used, the 'missing tooth' is achieved by bridging two of the 36 drilled holes with a dremel (or other tool of choice). This template is actually modeled with the wasted spark triggers 'A, B, C and D' indexed for position based on the notch in the damper, there is also a raised bump indicating the location of the sensor with the damper at top dead center or 'TDC'. If a different sensor location is selected you will need to 'bridge' a different set of holes such that the first 'non-holed' segment or 'tooth' is at the required trigger angle. In this case all 'triggers' are 40 degrees before piston top dead center. This template is a snug fit onto the damper, was printed in PLA with a 0.2 resolution.
