I'm in the process of rebuilding my 20r, and while cleaning everything for the reassembly I noticed that the teeth on the oil pump drive gear (the one that slides on the end of the crank) are fairly worn. I was expecting to get this with my new oil pump , but it wasn't included <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> . I wanted to check w/ the board whether this was a part normally replaced w/ the pump before I called engnbldr and asked him. I know he's busy and the less I call him the sooner my head will be done <img border="0" title="" alt="[Big Grin]" src="images/icons/grin.gif" /> .
