Hey guys,

In the process of doing a mock build, and i was going to use the old cam thrust bearing but found there to be about 1mm of endfloat, way to much, so i just bought a new one, and have the same problem.
Just wondering what the solution is, all that i can see is to have the timing gear plate machined down, or to machine the face of the oil pump down? any others?
Also, does it matter which way the thrust plate goes, in relation to the hole, which i assume is for oil to come threw.
Cheers
Nathan

There is no normal amount of endfloat on a Mini Cam. The lobes are not (or shouldn't be - depending on who last ground it) parallel on the faces to the shaft centre line so that in operation it does actually have side thrust in to the cam thrust plate.

Cam endfloat should only be about .005". It's determined by the thrust plate thickness and the shoulder on the sprocket.
If you have a new thrust plate, do the cam nut up, measure endfloat, and face off the back of the sprocket hub to reduce the float.

That would be a running clearance rather than an end float and yes you would want a minimum 5 thou here.
