simple test

That is a simple test,It should be done without the seals installed under the pump.You turn the crank without rods for a rotation feeling backlash as it goes through a revolution.You also feel the connecting shaft between the intermediate shaft and oil pump that is splined on each end.Push it fore and aft as you rotate and make sure it slides back and forth freely.This indicates the shaft is straight.If you rotate the crank and the intermediate shaft moves up and down that means the aluminum gear for the intermediate shaft has an issue between two teeth.Change the gear or file the offensive area down.Simple test.Ciao Fred
