65. Apply loctite 222 to 4 10-32 x 1 socket head cap screws. Install the
motor to the motor mounting bracket and nut plate using the cap
screws. Do not tighten at this time, the screws will be tightened after a
later adjustment.
66. Install the timing belt on the motor pulley then install the motor as-
sembly to the motor mounting bracket using the two 1/4-20 x 7/8 and
two 1/4-20 x 2 1/2 socket head cap screws. Engage the other end of
the timing belt on the gear belt pulley.
67. Slide the compression spring through the bottom of the motor mount-
ing bracket and secure the spring plate to the motor mounting bracket
using the two 1/4-20 x 1 socket head cap screws, compressing the
spring while tightening the screws.
68. Set the automatic belt tensioning assemblies as follows.
- Loosen the 1/4-20 x 2 socket head cap screws in the idler plates,
allow the spring to tension the belt then tighten the cap screws.
- Loosen the four 10-32 x 1 socket head cap screws in the chain
drive motor, allow the spring to tension the motor then tighten
the cap screws.
NOTE
Because the adjusting block is not symmetrical, the 0.38 inch flange
must be located at the bottom, as shown.
69. Apply Magnalube to the outer threads of the jack screw. Using Loctite
242 on the threads of the jack, install the jack, adjustment block and
jack screw to the rear flange of the housing. Adjust the height of the
adjusting block to 1.928 inch and the height of the jack screw to 1.63
inch, as shown.

70. Using Loctite 222 on the threads of the two 10-24 x 1/2 socket button
head screws, install the head counter bracket to the housing using the
cap screws. Install the counter to the head counter bracket using the
two 6-32 x 1/4 socket flat head screws.
71. Install the two chain clip guides to the housing using the four 10-24 x
3/8 socket head cap screws. Do not tighten the screws, as these will be
removed for head chain installation.
72. Using Loctite 222 on the threads of the four 6-32 x 1/4 socket head cap
screws, install the two light source blocks to the luminator assembly
using the cap screws.
73. Using Loctite 222 on the threads of the two 6-32 x 3/8 socket head cap
screws, install the luminator assembly to the BEC bracket using the cap
screws and flat washers.

74. Apply Magnalube to the pin of the BEC bracket assembly then install
the BEC bracket assembly into the housing and secure it in position us-
ing the spring washer and the retaining ring.
75. Using Loctite 222 on the threads of the locator pin, install the locator
pin in the housing.

76. Install the grease fittings into the housing. Using the grease gun with
Ultra blue grease, apply the grease to the grease fittings until a slight
amount of grease is seen at the spacers.
77. Install the required icor clamps to the housing using 8-32 x 3/8 socket
head cap screws with loctite 222. All systems require 3 3/16 inch
clamps on the left side of the housing, and systems equipped with an
expanded range verifier require 3 additional clamps on the right side of
the housing. Refer to the assembly drawings section in the front of this
document for locations.

79. Install the ends of the fiber optic cables flush with the surface of the
missing part detector. Install the fiber optic cables so there is a dimen-
sion of 7.00 +/- .06 inch from the edge of the sensor assembly to the
end of the cable. Refer to the assembly at the front of this document
for details on the sensor cable assembly.

80. Rotate the pinion shaft, as shown above, so the smooth side of the pin-
ion is visible. Insert the assembled tooling into the tooling housings.
81. While holding the two driver bodies extended in the up position, ro-
tate the pinion, as shown above, and engage the first tooth on the
driver bodies with the first tooth on the pinion.
82. Manually rotate the pinion shaft until the tooling is in the full down
position (the 5/16 allen wrench may be needed).
NOTE
This step ensures that the cam follower is on the proper side of the cam
lobe when the head drive axis is zeroed.
83. Attach the loose end of the extension springs to the pins on the shear
blades.
NOTE
Refer to the assembly at the beginning of this document for details
pertaining to the routing of the electrical and pneumatic lines.
End of procedure.
