Hi all
Just curious. How critical are you regards pulley alignment? The belt manufacturers quote 1/2 degree and three planes. There are limited means of adjustment.
Fore and aft with shims/spacers is one. But I'm finding my water pump is 1 1/2 degrees vertically out compared to the crank pulley. This is throwing off the power steering pump which is hung off the water pump
Without re-machining the pump the only way I can think of is to pad out the gasket .

For me it is very critical. High RPM could throw the belt. I use a straight edge across both pulley's to get them straight in the horizontal and a angle finder for vertical.
Machine spacers as needed till it's right.
Works for me.

Hi Dave  thanks for reply. Much appreciated. I'll keep at it till I get within 1/2 a degree.   Ho  Hum  The alternator is the only one at 0 deg. relative to crank pulley and that took 5 attempts welding and re-drilling the brackets.
