Waterpump Gear Spline

[dezracer]

Somehow I managed to shear the gear spline for the waterpump on the crankshaft.  By any chance does anyone have a pick of what a good one looks like?  The gear just spins freely in the crankshaft right now.  Also how would I go about getting a broke off piece outof the crankshaft without taking the whole lower-end apart?  

Thanks,
Chris

I had to replace the water pump gear on the end of the crankshaft recently.  It's a press fit into the crankshaft.  No way to pull it out if it's in there tight.  I had to break the gear off, drill out the center of the shaft (it's soft enough to drill) then take a dremel with a carbide cutter bit and work sideways thru the case hardened surface of the shaft and break the pieces out.

Thanks dude, your a life saver.  I figured it was something like that.  I couldn't figure it out and I almost just put it all back together.  I've asked about 4 mechanics and none of them could tell me the answer to that question.  You rock.  I need to buy you a cold one.

Thanks,
Chris
