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.

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
