AFAIK, When first sold by SAAC, they sold the IPSCO water pump pulley. They changed suppliers at a later date.
SAAC website currently does NOT list the water pump pulley??
The SAAC pulley I won at a Fun Rally is 4.90" in diameter.
IPSCO still lists theirs - $85 - no description of diameter.
Stock cast iron pulley was 5.5" in diameter.
