Case 500

[Bill from Scotland]

Couple of 500 questions:
What?s a typical or acceptable oil pressure on a warm engine?
Can the belt pulley be disengaged apart from pulling back in the clutch lever?
What effect does a poor Powrcel have in the running?

I think the manual says 40-45 pounds oil pressure. Mine carries just below 40 on a warm engine. Belt pulley cannot be dis-engaged...runs when the clutch is engaged whether in gear or out. Bad power cell would have a miss on that cylinder. Did you check valve lash?
