Figure 103 – Gear pin and first gear in final position
Use a bit of grease to stick one of the nylon thrust
washers into position inside the right-hand inner
sidewall of the focus gearbox housing (see
and apply grease inside the hole as well. Partially insert
the second gear pin into the greased hole in the housing
in preparation for the installation of the second gear.
Figure 104 – Washer and pin ready to receive second gear
Apply a light coating of grease onto both end faces of
the second gear. While holding the second gear in the
proper position within the focus gearbox housing, press
the second gear pin into the focus gearbox housing until
the pin engages with the hole in the second gear, but do
not press it to the point where the pin protrudes from
the opposite end of the gear (see

Use tweezers or needle-nose pliers to carefully slide the
remaining nylon thrust washer (greased) in between the
left-hand side of the second gear and the left-hand side
wall of the focus gearbox housing (see
Figure 106 – Insert nylon washer on opposite side of pin
Look into the hole in the focus gearbox housing where
the nylon thrust washer was just inserted and
reposition the washer with a toothpick or tweezer tips
as necessary to properly align it with the hole, such that
the washer will not be damaged when the second gear
pin is slid into this hole. Apply grease to the inside of
the hole and slide the second gear pin into the final
position to retain the nylon thrust washer, being careful
not to damage the washer in the process. Make sure
that the second gear pin protrudes from both sides of
the focus gearbox housing by approximately the same
amount (see
Figure
107) and wipe away any grease
squeeze-out.
