This pulley will fit older Formula Ford 1600 water pumps with 1/2 inch diameter shafts. The pumps we currently carry have 5/8 inch diameter shafts and require the .62 Bore Water Pump Pulley (Part No. 166-02-.62).
The 44 tooth size is normally mated with our 30 Tooth 1.6L Crankshaft Pulley (Part No. 166-30) and the 180XL050 Water Pump Drive Belt (Part No. 166-01-180). This results in a 1.47:1 underdrive ratio on the 1600 to reduce cavitation at high RPM.
This cast aluminum pulley measures approximately 2 3/4" diameter, with a deep setback to minimize the cantilevered load on the water pump bearings.
Crankshaft pulley and XL drive belt are sold separately.
