Assembly
Step 1 (See Photo) Using a drill with a 3/16 bit CAREFULLY drill out the rivets
that attach the throttle body motor housing to the throttle body.
Step 2 Remove the motor housing from the throttle body by gently and evenly
prying the plastic housing up from the throttle body.

Step 4 Using a T-25 Torx, unbolt the motor from the throttle body.
Step 5 (See Photos) Using the puller tool remove the motor.
NOTE
To use the puller; lay it flat over the top of the motor. Put the self-tapping
screws through the small puller holes and tighten them with a ºîsocket
into the small holes on top of the motor until the screw heads touch the
puller. Insert the 4mm Allen heads into the threaded holes on the puller
and tighten them evenly against the throttle body. This will pull the
motor straight up and out.
The BBK throttle body is designed to accept the motor with or without
the circular clip
Step 6 Install the motor into the BBK throttle body and tighten the Torx bolts.
Step 7 Install the idler gear onto the BBK throttle body insuring engagement
onto the other gears.

Step 2 Using a 5mm Allen wrench and the supplied bolts, install the throttle
body onto the intake manifold.
