Reconditioning The Tilting Device - Volvo Penta AQUAMATIC 280 Workshop Manual

1c. Mechanical fault
Check to make sure that the cover does not press
against the limit switch by removing the cover and
testing the function of the tilting device. If the tilting
device functions with the cover removed but not with
the cover installed, remove part of the cover over the
limit switch, pressing on the switch. Check the clear-
ance between the cover and the limit switch.

Reconditioning the tilting device

1. Remove the cover and remove the limit switch
(37, fig. on previous page) and the bracket with
the relays (35) and (36).
2. Remove the nuts and the electrical motor (22).
3. Remove the locking washer (11) and the shoul-
der screw (10) and the sealing nut (9).
4. Remove the upper part (4) and lift out the gear
rod (5) the spring (21), the bearings (14) and the
worm gear (7).
5. Pull out the guide sleeve (18) and the worm
screw (8) along with the bearing (15).
6. Wash the parts and check the wear. Replace
parts if necessary.
7. Assemble the tilting device in the reversed order.
Grease the parts in an universal type of grease at the
assembly. Also fill the upper housing with grease.
Connect the minus (earth) wire (2) and (3) as indicat-
ed in the picture and the wire harness (1) to the con-
trol switch.
Checking after reconditioning
Check after the installation that the tilt and retaining
pawl mechanism function properly. When tilting, the
tilting device should release the retaining pawl com-
pletely from the adjusting pin prior to tilting the stern-
drive. Adjust the push rod length in accordance with
point 7 page 127.
When lowering the sterndrive, run the tilt motor until it
is automatically cut off and the warning light goes
out.
In case the sterndrive should not stay in the 'up' posi-
tion, the spring (21, fig. on previous page) is not
stretched sufficiently. Insert a washer underneath the
spring. Should it not be possible to depress the
sterndrive by hand (approx. 75 Kilos, 145 lbs) at the
trim tab, the upper part (4) must be eased off a bit.
NOTE! There is no need to lock the upper part. The
spring pressure is locking it.
