1. Remove the fan cooling belt from the engine.

2. Remove the four 1/4"-20 screws from the front water pump.

5. Remove the water pump from the engine. A few taps with a hammer will easily accompish this. 

6. Put the water pump in a heavy duty vise securing it to the water pump housing. 

7. Re-thread the four 1/4"-20 screw holes on the pulley hub with the correct machine tap tool.

8. Install the W-115 puller hub onto the pulley hub by centering it on the pulley then screw the four supplied 1/4"-20 screws through the tool and into the pulley hub until it is flush and secured to the pulley hub. 

9. Install the 1/2"-13" x 3" drive bolt into the tool with a 3/4" wrench. Make sure the drive bolt is centered on the bearing shaft. Hold the square nut on center of the puller tool with a 13/16" open end wrench. Slowly pull the pulley hub and puller tool assembly from the water pump. This should be done by hand and not with an impact wrench.
