REMOVING THE UNIVERSAL JOINT SHAFTS
Unscrew the four fastening screws from the shaft flange as shown in
figure 1 from the gearbox, ond remove shafts.
REMOVING AND REPAIRING OF THE PROPELLER DRIVING UNIT
Unscrew and remove the eight hexagon bolts with Double locking rings
ond disc washers, using a 14 mm wrench as shown
in figure 2, ond then draw the complete propeller shaft housing away
together with oval gasket from the bilge .
After cleaning, place the complete housing in a bench vice clamping
between light metal jaws, to avoid damaging.
Unscrew the small set screw in the cap nut, see figure 3, before
removing nut, and by using the special tool AC 25 draw the
propeller off from the shaft, see figure 4.
Remove both keys from shaft, grease nipple, locking ring, ond then
radial oil seals from housing.
Using a bronze or light metal drift, drive the shaft out of the
housing in the direction of the propeller.
IMPORTANT
While driving the shaft out, turn the shaft with one hand to ovoid
the locking ring of the roller bearing inside ring from
sitting behind the rollers, ond therefore preventing damaging the
roller bearing.
Remove the roller bearing inside ring from the shaft, ond from the
housing remove the roller bearing outside ring and taper
boll bearing, see figure 5.Clean all ports, and check for wear and
damage.
ASSEMBLING
Fit the locking ring ond use the special tool AC 28 for fitting the
roller bearing Inside ring on the shaft at the propeller end,
figure 1.
Clamp the shaft in a bench vice, and fit the following parts on the
splined end of shaft:
Locking ring. = a.
Snug fit washer. = b.
Toper ball bearing. = c.
Snug fit washer. = d.
Locking ring. = e.
Place the shaft in a position free from dust until fitting. = f.
Clamp the housing in a bench vice between light metal jaws, and fit
the snug fit washer into the bare at the flange end of
housing. Now take the already assembled shaft and fit into the
housing inserting from the flange end and drive to the
propeller direction, figure 2. Fit snug fit washer and locking ring.
Using o long connection pipe attached to a hydraulic greasing unit,
fill the housing with multi-purpose grease, until it comes
through the ball bearing.
Fit the roller bearing outside ring using special tool AC 26, and the
locking ring.
Remove and clean all surplus grease from bath ends of housing, and
using special tool AC 26 together with AC 27 fit the
radial oil seal, figure 3.
Fit locking ring into housing at the propeller end.
ATTENTION
At the propeller end of the housing are two radial oil seals fitted
in the following way:
The inside radial oil seal lip must face to the inside of the
housing. = a.
Radial oil seal lip must face to the outside of the housing. = b.
Fit locking ring.
At the splined end of the shaft, the oil seal lip must face to the
inside of the housing.
Fit the grease nipple and grease. This will fill the room between
bath radial oil seals.
Fit both keys in the shaft, then propeller with cap nut
NOTE
To lock the cap nut after final tightening, bore a hole with a 0,098"
(2,5 mm) diameter drill through the cop nut into the
propeller, and then screw the fillister head screw into position.
The propeller-driving unit is now completely re-assembled and ready
for refitting into the vehicle, but always re-new oval
gasket and Duba locking rings.
IMPORTANT
Always grease with Amsoil multi-purpose grease. On no account should
track roller grease be used.
