SBC:Centering crank pulley when spacing to align w/water pump
I am having a time finding a short waterpump that has the correct spacing so I have spaced out my crank pulley by putting 2 lock washers under each bolt between the pulley and balancer. Problem is the crank pulley is not staying concentric with the crank and I am concered with throwing the belt.
Anyone had this issue? |

I think Moroso and others sell crank pulley spacers to shim up that pulley while maintaining proper alignment. I would not use lock washers or flat washers to shim up the pulley. You could also try finding another water pump pulley that aligns better with your crank pulley.

It is actually the waterpump that is wrong, the pulley is factory. I bought a napa waterpump and it is too long by about 1/4". I took it back when I realized this but the next one they gave me was off by a little more than a 1/4"

JEGS carries crankshaft pulley shims part no 50400. Moroso has them under part no. 710-64031.
