DO 550 Clutch Fitting Instructions and Maintenance manual
Clutch alignment (Vertical)
The clutch is designed to fit between the winch and the deck organiser. Keep the rope deflection angle as small as
possible. When installing multiple clutches try to ensure the clutches with the higher loads has the least deflection
angle.

Clutch alignment (vertical)
The vertical angle of the line from the clutch to the winch should not exceed 10 degrees.
To reduce the angle either increase the distance between the clutch and the winch or raise and angle the clutch
using a pad made from teak or nylon.
Fitting Instructions
For single clutches use-drilling template on packaging
Tools required:
6.5mm drill bit
Pencil
Drill
Silicon based sealant
Anti corrosive jointing compound
M6 spanner
Screw driver or Allen key
Fastening required

Use 6mm (1/4”) Counter sunk stainless steel fastening, full nuts and penny washers to secure
An Anti corrosive jointing compound (Duralac or Tef-Gel) is required between the counter sunk screws and the
aluminium base of the clutch. Apply silicon or polysulphide sealant to the holes, the base of the clutch and between
the deck and the base to ensure a watertight seal etc.
To ensure the best watertight seal is achieved, we would recommend slightly tightening the bolts, allow the sealant
to cure for 24 hours and then tighten the bolts fully. This will allow the sealant to form a watertight gasket.

Assembling line into clutch
Ensure handle is open and pushed fully forward. The front of the clutch should be facing the mast; this is the end the
handle pivots on. Thread the line through the front bullseye, through the mechanism and out through the aft
bullseye.
When operating the clutch
For greater performance and rope grip raise the handle to the vertical and then push the handle back down into the
locked position before easing the load from the winch, this minimises the amount of travel the cam needs to make
before the cam is fully engaged.
Maintenance
Flush with fresh water on a regular basis
Apply silicone spray to handle area on a regular basis
Check wear on cam every 3 months
Check securing bolts are secure regularly
Check attachment bolts are secured regularly
