the deckplate on top of it. Bolt the deckplate
down using capscrews, washers and the
insulating bushes. Tighten them evenly to 50Nm
(37ft-lb).

Offer up, from below deck, the drive assembly
sliding the mainshaft through the deckplate,
taking care not to damage the deck bearing.

After aligning them correctly and choosing the
most suitable orientation for the gearbox, bolt the
Deckplate and Spacer Tube together, from
above deck, using the M12 Hex Head Bolts and
Spring Washers. Tighten them evenly to 50Nm
(37ft-lb).

Re-check that the position of the drive assembly
is satisfactory and convenient for connecting
power supply lines to the motor.

Apply grease on the Deck Seal and slide it down
the Mainshaft, taking care to avoid damage to it.
Push it against the Deckplate by approx 1.5mm
after initial contact (see Picture 2.3).

Insert the two Retention Clips into the groove in
the Mainshaft; apply some grease to help keep
them in position, if necessary.

Apply anti-seize compound generously over the
Mainshaft and keyway. Insert Key into the
keyway on the Mainshaft.

Assemble Drum making sure it sits nicely on the
retention clips (see Picture 2.4).

Assemble the Drum retaining nut.

Put the Retaining Washer on top of the
Mainshaft and secure it with the Retaining
Screw.

Insert the Cap, with o-ring, into the Drum.

2.5 POWER CONECTIONS TO HYDRAULIC MOTOR
Basic hydraulic schematic is shown in Appendix C.
Port sizes on the hydraulic motor and minimum hose
sizes are specified in Section 1.3.
After connecting the power lines, spray all ports and
fittings with anti-
corrosive waterproof coating, “CRC
3013 Soft Seal” or equivalent.
2.6 SELECTION OF MOTOR STARTER
Several AC motor starter options for windlasses are
available, each with characteristic current demands
and start load limitations. Maxwell recommends that
selection of the best motor start system be entrusted
to experienced persons familiar with anchoring
procedures and the vessel’s generating capacity.
"Direct On Line" starter is the simplest way of starting
an AC motor and it will allow the windlass to start
under full rated load. However, this method requires
relatively high momentary starting current, which
might cause an adverse effect to the rest of the
electrical system on board. See specifications for
!
The selection of the type of motor starter
should be done by a qualified electrical
engineer, taking into consideration the
power generating capacity on board.
Maxwell offers both advice and different
types of custom made starters to
complement our capstans.
