1.1Identifying the manual convertible winch

•Fig. 1.1.1

Pre Ocean winches, i.e. ﬁxed jaw Wave Grip winches, made before 1992 are NOT convertible.

Convertible manual winches made in August 2000 will be date marked H/00 on the centre stem, (H = August; 00 = year 2000). They also carry a blue sticker on the screw-on top-cap showing a winch handle and a hand operating an electric deck switch. These winches can be converted by adding the Power Drive Base (B) unit and the required Motor Gearbox (C), Control Box and Switch-gear (12 V or 24 V).

•Ocean Wave Spring manual winches made between 1992 and August 2000 are NOT ﬁtted with the necessary centre stem to convert to powered operation. A Centre Stem Kit (A) is available to convert the early Ocean Wave Spring winches from (1992 to July 2000). The part numbers are listed below. Pre Ocean Winches, i.e. ﬁxed jaw Wave Grip winches, made before 1992 are NOT convertible.

Winch Model			Description		Part Number

40		Centre Stem Kit		48040037


			Centre Stem Kit
	44		Centre Stem Kit			48044037

48		Centre Stem Kit		48048037

1.2Preparing the manual winch for conversion to electric

•Remove the winch from the deck (if already installed) and remove the Centre Plate, which is located on the underside of the Centre Stem, by using a soft hammer and punch (Fig. 1.2.1).

•Remove any sharp edges and clean, to remove all old bedding/ sealing compounds from the underside of the Centre Stem.

1.3Fitting a complete electric winch from new

•Test ﬁt the winch to the Power Drive Base and Gearbox to check the orientation and the necessary clearence needed

BEFORE DRILLING ANY HOLES.

•Now follow sections 1.4 and 1.5.

1.4 Positioning winch above deck

•Lewmar recommend that the rope enters onto the drum at an angle of –5° to –10° to the base axis of the winch. To achieve this angle it may be necessary to use a base wedge when installing the winch (Fig. 1.4.1). The winch must be mounted on an even surface.

Always keep in mind the space available below the deck for the motor gearbox.

-5° to -10°

•If practical, for best performance, the winch should be installed so that the output gear is situated in the optimum position in relation to the load (Fig. 1.4.2).
