4. Fit an O ring to the front casing. Check that sealing

surfaces are free of dust or scratches. Make sure that

an O ring is in place and will not be out of a groove.

Mount the front casing to the rear casing along with

a pair of mating parts (except the F400). Note that the

F402 and F403 have two pairs of them.

5. Fasten the front casing to the motor bracket.

Tighten the hex. socket bolts evenly. Tightening torque

is shown below.
