Figure 107 – Gear pins holding both gears

Use a 1.3mm Allen tool or driver to loosely reinstall the

two M2.6X4 setscrews to secure the gears onto the gear

pins. If necessary, readjust the positioning of the two

gear pins such that there is an equal amount protruding

from each side of the focus gearbox housing and then

tighten the two setscrews to secure the gears onto the

gear pins (see

Figure

108).

Figure 108 – Reinstall two setscrews to secure the gears

Reinstall the Focus Gearbox

Apply fresh grease to the teeth of both gears of the

focus gearbox, rotating them as necessary to ensure

complete coverage of all the gear teeth.

Note: Be sure to omit grease from the teeth of the

small-diameter side of the second gear if grease was

omitted from the brass focus rack, since the small-

diameter end of this gear meshes with the brass focus

rack (see

Figure

109).

Figure 109 – Apply grease to the teeth of both gears

Apply a small dab of grease between the two mounting

grease to hold them in place while you reinstall the

gearbox into the pillar arm (see

Figure 110 – Stick shims onto flanges with dabs of grease

Hold the focus gearbox up to the mounting surface of

the pillar arm casting and align the four holes in the
