I understand what the toothed wheel does, though people are talking about different sized wheels? What difference does this make and what do the numbers mean EG. 32-6 or 60-2 are a couple I have seen mentioned?

Toothed wheel - What do the numbers mean?
Moderators: JeffC, rdoherty, stieg, brentp
Anyone seen my teeth?
The standard design for the MJLJ is a 36 -1 toothed wheel on the crankshaft. 36 -1 means that there are 36 teeth evenly spaced around the outside of the wheel, with one missing (so there are actually 35 and a gap) to synchronize cylinder #1 TDC. If the engine is very unusual, or space makes mounting on the crank impossible, then a custom wheel can be made to mount on the camshaft, or in the distributor. Because both of these rotate at one half the speed of the crank, the wheel has to be made so that a gap passes the sensor every time #1 piston is at TDC. This is done by making double the teeth, with two gaps opposite each other, for a 72 -2 design.
That's great, cheers. It i
That's great, cheers.
It is what I thought but wanted someone "in the know" to confirm!

you & your teeth
We are intersted in making a toothed wheel to run inside our distubutor as we need to keep it to drive the oil pump & setting up a sensor on the crank pulley will be hazordous as we do a lot of off-roading and fear that it will be damaged. We understand the 72-2 tooth theory but are un sure to the smallest dimensions we can make the wheel. Also is there a sensor which could run at 90 degrees to the wheel i.e. vertical to a horizontal wheel. Anyone thought along these lines - Its a V8 (mate) - case you were wondering.

dont know if youve looked at
dont know if youve looked at this option already
why not make a toothed wheel to fit on the flywheel similar to the ford enduro engine this has raised blocks machined into the flywheel (oposite side to the clutch) then the sensor points at the flywheel at 90 degrees
vertical to a horizontal wheel just like you mention but on a bigger scale
i dont know what you have to work with its just an thought
