Crank Pulley Removal/Installation
• Removal of the factory crank pulley is done with a Subaru Crank Pulley Wrench (ST
499977300) or impact driver
• Clean the crankshaft and thread, then slide the GFB crank pulley on. Clean the pulley bolt
thread and tighten to a torque of 157 Nm
A/C Belt Replacement
• To replace the A/C stretch-fit belt, slide the supplied cable tie through one of the slots in the
pulley on the right-hand side. Then wrap it around the A/C belt so that when tightened, the
cable tie is holding the belt onto the ribs of the crank pulley
• Pass the belt completely around the A/C pulley, so the belt is positioned as shown below:
• Turn the engine over clockwise by hand again, this time pushing the top of the belt so that it
continues to feed straight onto the A/C pulley as you turn the engine
• Once you’ve turned the engine over about 180 degrees, snip the cable tie loose and check that
the belt is correctly seated on both pulleys. If not, continue to turn the engine whilst guiding
the belt onto the correct ribs of the pulley/s
