Lining up Flexible Coupling
Fit the key in place and slide on the driving half of
the coupling until the face of the coupling half is
about 1/16 inch out from the end of the shaft.
Tighten the locking screws.
NOTE: Two locking scre\\,'s are fitted in each coup-
ling half, one on top of the other.
M,ake sure that the bottom locking screw is
tightened firmly in place before fitting and
tightening the top locking screrv.
Fit the driven half of the coupling to the driven
machine. Lift the machine on to the block.
With wooden wedges, adjust driven machine until it
is approximately level, and at the same time see that
it is in line with the engine.
The two halves of the Coupling are the same dia-
meter. Using a metal straigJit edge across the
coupling halves, check if the diameters coincide on
top, underneath, and on either side. Shift the driven
machine and recheck with the straight edge at these
four points until correct.
Then, using a set'of feeler gauges, check the gap be-
tween the Coupling halves ,at the top, underneath,
and on either side. Shift the driven machine until
the gap is the same .a11 round the coupling, and, at
the .same time, check that the diameters coincide,
using the str,aight edge as in (6) above. The driven
m.achine must be adjusted until the maximum mis-
aiignment on the outside of the coupling is less than
.005 inch and the maximum variation in the gap be-
tween the coupling halves is less t,han .010 inch.
When the aiignment is correct, proceed to grout in
the bolts of the driven machine with a mixture of
tw,o parts of cle,an sand and one of cement. When
the holes are full, work the grouting under the
machine base so that it will sit on a firm, level
foundation. This must be very carefully done to pre-
vent the machine from getting out of alignment.
Next day, remove the wedges, tighten the found,ation
bolts, check the alignment, and, with the same grout-
ing mixture, clean up and surface the block.
Next day, shift the driven half of the coupling ,al,ong
the shaft to leave abofi I/32 inch gap between the
halves, and lock it in this position. Fit the rubbers
and pins to the coupling, fit locking nuts with spring
washers under them, and tighten.
The engine can now be started, but not before, as it
is essential that the block be allowed to set for at least
three days before the engine is started.

SOUTHERN CROSS DIESEL ENGINES
Eitting 2:l Reduction Box-
Mark KF-I
1. Take the Pinion supplied *'ith the Reduction Box and
slide it ,on until it is hard up against the Shoulder on
the Crankshaft. The Pinion Locking Screw must be
nearest th,e end of the Crankstraft, and it is important
to see that the Pinion is not put on the wrong way,
Slide fhe key into place and tighten the locking screw
rvith the spanner supplied.
2, Fit the studs supplied with the reduction box into the
Crankcase. Use two nuts locked together to screw
in the studs.
3. Clean the paint from the spigot ,on the crankcase.
Fit the gearbox gasket on to the studs ,and then put
the box in position, fitting spring washers under the
nuts. The reduction box may be mounted in any of
six different positions by altering it on the studs, but
it is preferabie to keep the drive shaft level with, or
below, the Crankshaft level.
4. Undo the nuts ,around the drive shaft bearing hous-
ing, and remove the housing, drive shaft, and bear-
ings. With these parts removed, the nuts c.an be
fitted to the two studs which p,ass through the back
of the box.
5. lVhen replacing the housing, position it so the filling
plug is at tlne 72 o'clock position, and the oil level
plug is at the 8 o'ci,ock position.
6. Remove the oii level plug and the filling plug and
pour Southern Cross Drive Gear Oil-E.P. S.A.E. 90
-into the box until it runs from the oil level hole.
Replace both plugs,
Drives from Reduction Drive Box
1. Belt Drive.
For a belt drive, make sure the key is in position in
the drive shaf't, then slide on the pulley and tighten
the locking screw.
Fit the starling handle clutch spacing collar on to the
drive shaft, and screw on the starting handle clutch.
Check for position in relation to compression with the
starting ,handle. By varying the thickness of washers
behind the starting handle clutch, adjust the starting
handie position, so compression is met on the puli up.
2. Flexible Co,upling Drive.
For ,a Flexible Coupling Drive, fit the parallel key in
the keyu'ay in the crankshaft and slide ,on the driving
half of the coupling until the f,ace of the coupling half
is about 1/16 inch out from the end of the shaft,
Tighten the locking screws.
The remainder of the installation of the flexible
coupiing and the lining up ,are done in a similar
manner to that described in section "Flexible Coupling
Drive frorn Crankshaft", on P,age 3.
Exhaust System
1. If an exhaust pipe is fitted, always turn the end of
the pipe downv'ards, so that any moisture which may
collect in the pipe will run away from the engine.
2, If. a long exhaust pipe is fitted, over 12 feet, use
11 inch pipe and keep it as free from bends as pos-
sible.
Lubricating System
Unscrew the oil filler plug and fill crankcase to the
bottom thread in the filler hole with Southern Cross
Engine Oil-Series 3-D.S. Service (S.A.E. 20). The
sump capacity is 4i pints.
