58. Using Loctite 222 on the threads of the three 6-32 x 7/8 socket head
cap screws, install the motor and motor bracket to the housing using
the cap screws.
59. Secure the coupling to the motor shaft using the screw in the coupling.
60. Install the motor plate to the housing using 4 1/4-20 x 1 socket head
cap screws and split lock washers.
61. Using Loctite 222 on the threads of the four 10-32 x 3/4 socket head
cap screws, install the motor on the head drive shaft ensuring that the
motor shaft engages the coupling. Secure the motor to the motor plate
using the cap screws.
62. Using Loctite 222 on the threads of the set screw in the coupling, se-
cure the coupling to the motor shaft using the set screw in the coupling.

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.
