Reinstall the Fine-Focus Knob with Attached Shaft
Clean all of the old grease from the fine-focus shaft
Use a pipe cleaner wetted with solvent to thoroughly
clean the old grease from the bore of the coarse-focus
shaft. Shoot a bit of fresh grease into the hole in the
coarse-focus shaft on the right-hand side of the pillar
arm. Insert the shaft into the freshly greased hole (see
Figure
91), and move the shaft in and out, while
rotating the knob, going progressively deeper each
time, until fresh grease is pushed out of the hole on the
opposite side of the pillar arm. This action should
thoroughly distribute the grease throughout the bore of
the coarse-focus shaft. Remove any grease squeeze-out
from the hole on the opposite side of the pillar arm.
