Positioning the OctoseŽ
Owing to the diverse number of turntable mounting
plates, these fitting instructions are generalised and the fitter will
have to use their own initiative as to the exact location, as many
factors are involved in a successful installation.
The general location is on the centre line, just in
front of the turntable. This varies with obstructions such as Pan-hard
rods or cross-members. The Ideal position is approximately 100mm in
front of the turntable feet on the centre line. If the turntable is a
high profile type, the bearing can be located under the table. For low
profile table, tilt to the maximum forward position, allow 100mm in
front. Mark this as centre for bearing mounting ring.
Option 1: Cut a hole 140mm in diameter in turntable mounting
plate and clean it up. Insert bearing mounting ring 10mm above
mounting plate. Stitch weld 4 X 25mm welds.
Option 2: Cut a hole 125mm in diameter in turntable mounting
plate and clean it up. Centre and clamp bearing mounting ring on top
of mounting plate. Stitch weld 4 X 25mm welds.
DO NOT FULLY WELD AS RING WILL SHRINK.
DO NOT FORCE RING INTO AN OVAL HOLE.
ALLOW FOR RAISED BATTERY BOXES OR ANY OBSTRUCTION
ABOVE CHASSIS LEVEL.
Using the Ripple Plate
An extension plate may be necessary to mount the
bearing housing. This is a plate 300mm X 170mm X 5mm with two
corners cut off at 45*. Use the same method of stitching ring in place
while bearing housing is centred and clamped. The ripple plate can
then be welded to the turntable.
The same as above applies for a standard
which ducts two (2) air, one (1) electrical, one (1) ABS, and one (1)
minor cable comfortably.
Ball Race with Hydraulics
Use an extension plate as above, but raise
the height, so the bottom of the OctoseŽ is level with the top of the
ball race to allow hydraulic hoses to enter through an opening in the
centre of the turntable plate and into the OctoseŽ at the rear. All
other hoses and cables enter up through the bearing. If there is no
access through the turntable plate, a hole of approximately 300mm
diameter should be cut under the centre of the king pin. Lay hoses
parallel to avoid cutting off air supply. This also simplifies adding
The OctoseŽ cover can be varied in height to
simplify the retention of hoses. Press in 4 Nylon clips (supplied).
Should hoses need greater retention, replace front clips with through
bolts. Retaining bolts can be used should the clips shear off.
Connection of Hoses
Disconnect hoses at the rear of mounting
plate to which the Suzie Coils are connected. Remove the two air lines
and replace cable mountings. Draw the Nylon tube back towards the
turntable as far as possible, and join the rubber hose with approved
Also extend the electrical cable so that it
is approximately 200mm longer that the air hoses. This prevents the
power cables doing a rotation of the OctoseŽ and prevents plugs being
dislodged. Zip tie the Nylon and power cables onto the existing
harness in the chassis rail to a point opposite the OctoseŽ bearing.
This now gives a short run across to the centre of the chassis to the
access hole in the bearing.
Replace air couplings onto barbed fittings. After
the trailer is connected, make sure truck will turn to full Jack-Knife
position, with a little spare hose still available.
