To insert the Seat Extension into the Heater (Figure 5-6):

1. Reapply the conductive grease on the seat extension without putting any grease on the threaded

shaft.

2. Position the seat extension so that the dowel pinhole on the seat extension faces toward the

backside.

3. Rotate the seat extension into the heater to spread the conductive grease evenly and to avoid

the formation of air pockets.

4. Thoroughly wipe off any excess conductive grease from the seat extension threads.

To attach the Heater and Seat Extension to the Lower and Upper Bodies (Figure 5-6):

1. Position the heater and seat extension to the lower and upper bodies as shown in the illustration.

2. Align the attachment holes for the heater, seat extension, and the upper and lower bodies.

3. Using a torque wrench, install the two screws and tighten to a torque of 0.79 N-m (7 in-lb).

4. Set aside the assembled components.
