Engine Step 2 - Harley Oil Pump

Life's a bitch...   Thank God there's Harleys...

After cleaning and inspection, we re-assembled the Harley oil pump that fits at the bottom of our 1973 Ironhead engine. Other than new gaskets, we were able to use all the original Harley parts. After turning the crank shaft to the position where the indicator line shows right throught the inspection hole as shown in the photo below, we could shift the oil pump shaft right in very easily.
