Reach around to the front of the pillar arm and raise the

sliding focus block to gain access to the lower screw

hole in the brass focus rack. While holding the sliding

focus block in this position, use a 2.5mm Allen tool or

driver to reinstall and tighten the lower M3X8 hex

socket-head cap screw (see

sliding focus block back to its lowest position and

tighten the upper screw.

Grease the Brass Focus Rack (Optional)

Note: This step is optional and may be omitted if the

equipment will be used in an environment where debris

might accumulate on a greased focus rack, which would

foul the rack-and-pinion focus block mechanism.

Apply fresh grease to the teeth of the brass focus rack,

manipulating the sliding focus block as necessary to

expose the face of the rack to facilitate the application.

Make sure that the entire face of the brass focus rack is

covered with greased (see

Figure 96 – Grease the teeth of the focus rack (optional)

Disassemble the Focus Gearbox

The focus gearbox must be fully disassembled so that

the old grease can be thoroughly removed from the

disassemble the focus gearbox, first rotate the gears

until the two hex-head setscrews are accessible. If the

gears cannot be freely rotated due to thickened grease

in the gearbox, use a heat gun to heat the entire focus

gearbox, or apply a drop of a suitable penetrating oil to

both ends of the two gear pins, which should loosen the

old grease enough to allow the gears to rotate. Once

the heads of the setscrews are accessible, use a 1.3mm

Allen tool or driver to remove the two M2.6X4

setscrews securing the gears to the gear pins (see

Figure

97).

Figure 97 – Remove two setscrews securing the gears

After the setscrews securing the gears to the gear pins

have been removed, use the tip of a screwdriver (or

similar blunt tool) to press the two gear pins free of the

focus gearbox housing (see

a heat gun to heat the gearbox, or use a suitable

penetrating oil, to loosen the old grease enough to

allow the gear pins to be pressed out. Once the gear

pins have been pressed out of the gearbox housing,

remove the two loose gears and the four nylon thrust

washers that were present at the ends of the two gears.
