3. Install a new decal (if necessary) on the rim of the valve spool.
NOTE: Align the indentation on the rim with the zero (0) mark on the decal.
4. Place the washer (04396) on top of the silencer (04398) and tightly screw the
silencer into the valve spool (58733-1).
5. Slide the valve spool (58733-1) into the bore in the manifold block (58642-1).
6. Secure the retaining disc (58734-1) on the back of the valve spool with the machine
screw (7101-1-3).
7. Set the chopper speed regulator to zero by aligning the zero mark on the decal with
the line on the chopper manifold.
Install Blower Screw
Screw the blower thumbscrew (5103-11-1) into the hole in the manifold block. (The
hole in the manifold block is aligned with the blower tube).
NOTE: The blower thumbscrew clears the chopper of excess glass buildup.
Opening this valve too much distorts the fan pattern.
Connect Base Plate to Air Motor
1. Place the set screw (F-SS-04C-06-SS) for tightening the air motor into the hole in
the base plate (5113-3-1).
2. Lubricate the mounting flange on the air motor with Lubriplate (08465).
3. Insert the air motor into the base plate (7102-11-6).
NOTE: Align the blower tube and air motor with the proper holes in the base
plate. The air motor goes into the holes on the side of the base plate with the
raised platform.
4. Tighten the set screw (F-SS-04C-06-SS) to hold the air motor in place.
Install Blade Rotor
1. Slide the blade rotor onto the motor shaft, aligning the flat side of the shaft with the
two screws on the side of the blade rotor.
2. Tighten the hex screws gently, but do not tighten securely yet.
NOTE: Position the rotor so that, as it rotates clockwise, the retainer and spring
contact the rubber roll before the blade does.
