[Healeys] Cam end play

[richard mayor]

Mike
That locating plate is actually the "thrust plate". The camshaft is located
"front to back" by the oil pump driving spindle that pushes the camshaft
forward into that thrust plate.  A word of caution. A 100-6 rotor style oil
pump puts way too much force into that camshaft and into that thrust plate.
That's why later 100-6 thrust plates had oil grooves machined into them.  The
3000 engines used the gear style oil pump and the problems went away.
