Procedure After Starting; Engine Speed; Running-In; Oil Changing During Running-In - Volvo Penta TAMD60A Instruction Book

Procedure after starting

1. Never race a cold engine. Run it warm under light
loading or at rapid idling speed.
2. Check that the warning lamp for the oil pressure (17,
figs. 7 & 8) goes out immediately after the engine has
started. The oil pressure for the engine should be
between 300-500 kPa (3-5 kp/cm
normal operation. The warning lamp lights and the si-
ren sounds if the pressure drops below 150 kPa (1.5
2
kp/cm = 21 p.s.i.), in which case the engine must be
stopped immediately in order to avoid engine damage.
3. Check that the charging warning lamp (16) goes out.
4. Keep the button (1, fig. 21) on the control pushed in
and pull the control lever to neutral.
Check the oil level in the Twin Disc reverse gear while
idling and with the control lever in neutral.
5. Check the engine temperature.
NOTE! The temperature should be between 65–95°C
(150°–203°F) during running. If the temperature rises
abnormally, open the air cocks on the thermostat
housing and the turbo for a few seconds in order to
evacuate any air in the coolant system. Top up with
water if required.
6. Check the oil pressure for the reverse gear. See
"Technical data".

Engine speed

NOTE! Special regulations apply with regard to
running-in, see under the heading "Running-in".
Cruising speed is equal to about 3.3 r/s (200 r/min.) below
the maximum speed reached for a given load condition.
This results in economical and favourable operation.
Do not run for long periods of time with the engine speed
below 23.3 r/s (1400 r/min.) with the engine under load.
If the speed tends to drop gradually, this may be due to dirt
or marine growth on the bottom of the boat. For this reason,
the hull below the waterline should always be thoroughly
cleaned in such cases and treated with anti-fouling paint
before other measures are taken.

Running-in

When the engine is new it should be run with a certain
amount of caution during the first 200 hours. The same
applies to a newly reconditioned engine. Read the instru-
ments often and make sure that they give normal readings.
Run at full speed only during short periods for the first 50
hours. During this time, cruising speed should also be re-
duced so that it is at least 5.0 r/s (300 r/ min.) below the
maximum speed attained.
The cruising speed can subsequently be increased gradu-
ally, but as a rule, it should be approx. 3.3 r/s (200 r/min.)
below the maximum speed attained.
If a fresh water filter (Perry) is fitted it should be changed for
the first time after 150 hours of operation.

Subsequently, the filter is normally changed every 600
hours. When removing, the entire filter is unscrewed in the
same way as the lubricating oil filters.

Oil changing during running-in

Change the oil in the engine for the first time after running
25 hours.
