This will allow access to gearbox mounting bolts,
allowing the gearbox to be removed without
dismantling the topworks.
A drawing showing the deck cutout details is
enclosed with these instructions to assist in marking
out for all the drilling and cutting in the deck, required
for installing the capstan. Before drilling and cutting,
check the marked out area is dimensionally correct
and make any necessary corrections.

Boats with steel/aluminium construction.
It is very important to insulate the deckplate
from the boat with a non conductive gasket.
Mounting studs and fixings under the deck
should be insulated. Anchor and chain
should also be insulated, including rubber
lining, chain locker and fixing for the end of
the chain to the hull.
Without these precautions severe
electrolysis can occur.
It is not necessary to separately earth the
Capstan, as the electric motor is of the
isolated earth type.
2.3 PREPARATION OF THE CAPSTAN
Remove capstan from its packing case.
Disassemble the capstan in the following order (refer
to drawing in Appendix B):

Remove the cap from the top of the capstan,
taking care not to damage the polished surface.

Undo and remove the retaining screw and
retaining washer under the cap, using a 17mm
socket spanner.

Remove drum retaining nut, drum, key, retention
clips and deck seal.


packing case.
Maxwell strongly recommends generous application
of a high quality anti-corrosive paste or coating to the
mating sections of main shaft, drive key, flanges,
screw threads, dowels and other surfaces that are
likely to seize after being in contact for a prolonged
period of time.
Also ensure anti-corrosive coating is liberally applied
to the inside wall of the spacer tube.
2.4 INSTALLING THE CAPSTAN
Refer to the drawings in Appendix B for help with
identifying components and installing them correctly.
Extra care should be exercised when handling
polished parts to avoid any damage to polished
surfaces.
When assembling the parts, apply an anti-seize
compound generously over all screw threads, keys
and keyways, main shaft and inside the spacer tube.
Proceed with installation in the following order:
