Instructions

Note: Before following these instructions, attach the wheel drive to the wheel (refer to the

ST4000+ Owner's Handbook for details).

Preparation

1. Cut out the appropriate 'wheel spindle' circle (at the center of this template), so you

can place the template over your wheel spindle.

2. Rotate the template to determine suitable locations for the motor tube and bracket:

• You may be able to orientate the wheel drive so the motor tube runs alongside the

pedestal. In this case, proceed to 'Cutting the bracket'.

• There are two alternative slots for the bracket in the back cover of the wheel drive

(Slot 1 and Slot 2).

• Locate the motor tube where:

• a 55 mm (21/8 in) hole can be cut in the bulkhead/pedestal (if required)

• the seal and ring can be secured around the motor tube

• there is sufficient space behind the mounting location to allow at least 10 mm

(0.4 in) clearance around the motor (see diagram below)

CAUTION: 

Mount the drive so the motor tube is as far as possible from the boat's

compass to reduce the risk of deviation.

3. Use the template to mark the locations of the bracket and motor tube.

Cutting the motor tube hole

1. Drill a small pilot hole at the center of the intended motor tube location so you can

check there is sufficient clearance behind the mounting location.

CAUTION: 

Before you cut the motor tube hole, check behind the intended

location for any steering mechanisms, cables or obstructions.

2. Cut a 55 mm (21/8 in) diameter hole at the motor tube location and smooth any

sharp edges.

3. Assemble the ring/seal onto the motor tube:

• fit the metal ring first

• then fit the rubber seal: the seal will self-center on the tube

4. Temporarily mount the wheel and drive onto the spindle, allowing

the motor tube to pass through the hole.

5. Press the seal against the bulkhead/pedestal, orientate the seal as

required, then mark the centers of its mounting holes.

Cutting the bracket

1. With the wheel still in place, hold the bracket under the wheel

drive so you can mark dimension A – the distance between the

mounting surface and the rear edge of the wheel drive front cover.

Note:If the wheel is bent or not running true, dimension A will

change. Measure the shortest distance.

2. Use a hacksaw to cut the pin 10 mm (0.4 in) LONGER than

dimension A. Remove any sharp edges with a file or sandpaper.

3. Position the bracket so the pin is in the middle of the relevant slot. 

Note: the center of the bracket pin should be 154 mm (6.1 in) from

the center of the wheel spindle.

4. Mark the center of the bracket's mounting holes then remove the

wheel and drive.

Attaching the bracket and ring/seal

1. Drill 4 mm (5/32 in) diameter pilot holes for the bracket and

ring/seal mounting screws.

2. Attach the bracket using three self tapping screws

(No 10 x 3/4 in). Note: on fiber-glass surfaces you may

need to replace the mounting screws with suitable

nuts, bolts and washers.

3. Remove the ring/seal from the motor tube, then use

three self tapping screws (No 10 x 3/4 in) to attach

them to the mounting surface. 

Note: make sure the rubber seal is closest to the

surface (i.e. with the metal ring on top).

Final assembly

1. Attach the drive cable to the socket on the motor

tube, then secure the cable so it is clear of any

moving parts.

2. Fit the wheel and drive back onto the wheel spindle

and fully tighten the wheel nut.

3. Route the cable to the control unit, bearing in mind

the EMC guidelines in the ST4000+ Handbook.
