Figure 34 – Remove centering plunger from the bore
Reassemble the Centering Plunger
Use a cotton swab wetted with a suitable solvent (e.g.,
acetone) to clean any old grease from the plunger and
spring. Also clean the bore in the condenser slide, the
face of the dovetail slide, and the bearing surfaces on
the face and bevels of the dovetail slide (see
).
Figure 35 – Clean grease from bore and dovetail slide
Apply fresh grease to the centering-plunger bore in the
condenser slide (see
Figure 36 – Apply grease to the centering-plunger bore
Insert the centering plunger, with attached c-clip, into
the centering-plunger bore in the face of the dovetail
slide (see
Figure 37 – Reinstall plunger and c-clip into bore
Insert the plunger-extension spring into the centering-
plunger bore in the face of the dovetail slide (see
Figure 38 – Reinstall plunger-extension spring into bore
Compress the extension spring and reinstall the
plunger-retaining screw into the bore of the dovetail
slide, to retain the extension spring and centering
plunger (see
Figure 39 – Reinstall the plunger-retaining screw
Use a suitable slotted screwdriver to tighten the
plunger-retaining screw such that the head of the screw
is slightly recessed relative to the face of the dovetail
slide (see
). This will prevent the
screw from interfering with the mounting of the plastic
condenser-height rack. Wipe off any grease pushed out
by the plunger.
