Anyone with a P40 engine lying around? Need measurements.

[David_S]

I am proposing to fit an EDIS ignition system to the P40 engine on my old MQ to complete my engine modification programme. Would be nice to get rid of the dizzy, and the Megasquirt ecu is easy to set up for EDIS. However EDIS requires the fitting of a trigger wheel to the crankshaft. I hope to get or make a trigger wheel which I can bolt to the rear flange of the alternator/water pump pulley. I can't get at mine easily to get exact measurements and don't really want to pull it apart unless I have to. Thought someone might have a P40 sitting out in the shed somewhere which could provide the measurements I need.

They are:-

1) Outside diameter of crankshaft alternator pulley
2) Rear flange width of crankshaft alternator pulley (the flat area to which I hope to bolt the trigger wheel)
3) Approx flange thickness of pulley to see if it is thick enough to drill and tap for the trigger wheel fixing bolts.
3) Shaft diameter
4) The clearance between the pulley and the timing cover which would give me an indication whether there is room for a trigger wheel and how thick I should make it.

The pulley on my engine is the triple pulley - inner water pump/alternator, middle power steering, outer (nearest radiator) AC. Unfortunately it is not the same as either the L28 or SD33.

I would really appreciate it if someone has these dimensions as it would save me a lot of dismantling/reassembling.

Surely someone out there has a P40 engine lying around ''


I suppose I will have to pull mine to pieces?''''
