Remove the Fine-Focus Thrust Washers

Figure 19

shows the two fine-focus thrust washers that

are located beneath the left-hand fine-focus knob.

These consist of a curved-disk spring washer, which sits

on top of a nylon thrust washer, which in-turn sits on

the shoulder of the brass shaft mount. These two

washers will be visible once the left-hand fine-focus

knob has been removed. Although these washers are

normally found in position over the shoulder of the

brass shaft mount (see

them there, look inside the fine-focus knob which was

removed from the left-hand side.

Figure 19 – A view of the fine-focus thrust washers

Remove the curved-disk spring thrust washer from the

nylon thrust washer first, and then remove the nylon

thrust washer from the shoulder of the brass shaft

mount. The spring thrust washer will come off easily,

but the nylon thrust washer may be somewhat

stubborn due to the presence of dried grease beneath

it, holding it in place. If this proves to be the case, use

gentle heat and a sharp X-Acto® knife to separate the

nylon thrust washer from the shoulder of the brass

shaft mount (see

or the nylon thrust washer. Also, be careful that you do

not damage the nylon thrust washer with the X-Acto®

knife blade.

Remove the Left-Hand Coarse-Focus Knob

Use a suitable JIS screwdriver to remove the three

M2.6X5 screws securing the left-hand coarse-focus

knob onto the brass shaft mount (see

that these screws can be somewhat stubborn, and it is

surprisingly easy to strip the screwheads while trying to

remove these screws. To improve the odds of removing

these screws without damaging the screwheads, apply

gentle heat with a heat gun (don't melt or deform the

plastic knob) and then seat the screwdriver tip into the

screw heads and lightly tap the screwdriver handle with

a soft-faced mallet to try to break the screws loose

before removing them. Do not strike the screwdriver

handle too hard with the mallet or you may crack the

plastic knob.

Once the three screws securing the left-hand coarse-

focus knob onto the brass shaft mount have been

removed, pull the knob free of the brass shaft mount

(see
