5CT & 7CT WINCHES
Composite Technology (CT) Winches from Lewmar are the culmination of
new materials technology coupled with Lewmar’s innovative research and
development programme. Special plastics that are fibre re-enforced are
used to ensure a strong lightweight structure with a high power to weight
ratio. Lightweight yet immensely tough for their size, these winches have
been designed to exacting quality standards, well maintained and properly
used these winches will provide a long service life.
Installation.
Dismantle the winch as per the instructions below. Ensure the deck is flat
and suitably strong enough to withstand the winch loads. Drill the holes
through the deck. Mount the winch base to the deck and fit the mounting
screws. Use a metal or Plywood lower deck plate to re-enforce the deck
where required. Tighten the mounting screws and use lock nuts or suitable
thread locking adhesive.

Assembly.
1. Remove the spiral locking
Circlip (1).
2. Remove Top Plate (2) and
lift off Drum (6).
3. Remove the Spindle (5) by

5. Lift off drum thrust washer
from top of centre stem.

the reverse sequence.
Service.
Lewmar winches like any other precision engineered product, must be
serviced regularly. As winches carry deceptively high loads, regular serving
with attention to correct assembly and condition of parts is vital to the safety
and performance of the winch. Never use a damaged or worn part, always
fit new. Always clean the winches off after use. At least 2 or 3 times during an
active sailing season, winches should be stripped cleaned and lubricated.
At the end of each season the winches should be stripped cleaned thoroughly
inspected, parts renewed where required, lubricated and assembled.
Maintenance.
Clean the drum using fresh water. Lubricate the winch drum bore, Centre
Stem, Spindle and Drum Thrust washer with winch grease. Clean and lightly
grease the ratchet tracks. Pawls should be clean and lightly oiled with winch
oil. NEVER grease a pawl.
