GFB Power-Up Pulley Kit (part 2014) - Manual (Page 2)

GFB Subaru Power-Up Pulley Kit Fitting Instructions (part # 2014)
The GFB Power-Up Pulley Kit is designed as a replacement for the original pulleys and increases
engine power and response by reducing the inertial and driven loads, and also by under-driving the
alternator and power steering pump.
GFB recommends that this pulley kit is installed by a qualified motor mechanic, using the Subaru
workshop manual guidelines.
Note that only the alternator/power steering belt is supplied with this kit, as the crank pulley is
designed to re-use the existing factory A/C belt.
Power steering/alternator belt and pulley removal
• Removing the plastic pulley/belt cover and intake snorkel
• Using a 19mm socket/wrench, loosen the power steering pulley nut – in most cases the belt
tension will hold the pulley firmly enough to crack the nut. If not, an impact driver may be
required. It is NOT recommended to lock the power steering pulley with a bar through the
holes, as this could cause damage to the pulley or the power steering pump
• Locate the tensioning and locking bolts on the alternator. The locking bolts are the horizontal
ones located on either side of the alternator, which should be loosened a few turns first with a
12mm socket. Then loosen the tensioning bolt so that there is enough slack to remove the belt
• Lift the alternator as high as possible, then use an impact driver with a 24mm socket to remove
the nut. You’ll need to hold the alternator pulley firmly with a rag or glove
A/C belt removal
MY08-on models typically have a stretch-fit belt on the A/C, as there is no tensioner pulley fitted. For
these models, follow the guidelines below. For earlier models with a tensioner, simply loosen the belt
tension and remove.
• To remove the stretch-fit A/C
belt, make sure the car is in
neutral with the park brake on
• Use a 22mm socket with a
ratchet driver to turn the engine
over clockwise (NEVER turn
the engine backwards) whilst
pulling the top of the belt
towards you to walk it off the
A/C pump pulley. Take care
doing this to ensure your fingers
do not get jammed by the belt
