The 1" Extension - Volvo Penta AQUAMATIC 280 Workshop Manual

The 1" extension

Coat the contact surfaces with a sealant. Use the 3
new O-rings and the oil pipe from the extension kit. In-
stall the extension on the lower gear housing.
Install the locking ring in the splines sleeve. Turn the
end with locking ring downwards and then install the
sleeve on the lower vertical shaft.
Install the stud screws 'D' in the intermediate housing
'E'.
Coat the contact surfaces with a sealant and place
the intermediate housing on the extension.
NOTE! Do not forget the O-rings! Tighten the bolts 'F'
and nuts 'G' (1" extension) evenly and in diagonal se-
quence. Use the existing washers 'H' on the nuts. On
the 4" extension the screws 'K' and the washers 'L'
are used instead of nuts and washers.
Tightening torques – see the picture!
Install the cover over the shift mechanism.
If the paint has been damaged, use touch-up paint to
repair. See under Accessories – Aquamatic .
Fill up with lubrication oil. Regarding oil quantity and
oil quality, see chapter Technical Data . Check the oil
level with the sterndrive fully lowered. Let a few min-
utes pass after you have shut down the engine before
you start checking the oil level. Push down the oil dip-
stick as far as possible, however, without tightening it.
Lift up the oil dipstick and register the oil level. Top-up
if necessary.
NOTE! Do not forget the small O-ring underneath the
oil dipstick head.
