Air Cleaner; Cooling System - Volvo Penta TAMD60A Instruction Book

21. Air cleaner

TAMD70C, AQD70C
Clean the cleaner after every 600 hours of operation.
Undo the clamps round the cleaner and remove and wash
the filter element in white spirit or diesel fuel oil. Allow the
filter element to drip-dry and then moisten it with engine
lubricating oil and refit it.
All other engines
Replace the filter with a new one after 600 hours of opera-
tion. Under favourable conditions the time between the
changes can be extended.
1. Clean the rubber tube to the filter. Slacken the hose
clamp (1) and the attaching strap (2) for the filter.
2. Remove the old filter and discard it.
3. Check that the rubber tube is not damaged. Fit the new
filter after making sure that it is absolutely clean.
4. Start the engine and check that there are no leakages.
NOTE! Make absolutely sure that no impurities enter
the engine.
Crankcase ventilation
TAMD60B, TAMD70D and AQD70D have a paper element
for the crankcase ventilation. This filter element should be
replaced with a new one after every 600 hours of opera-
tion.
22. Injectors, checking
After every 600 hours of operation the injectors should be
cleaned and checked, with regard to opening pressure,
spray pattern and leakage, by authorized personnel. For
injector values, see "Technical data".
23. Cooling system, checking
Check the cooling system for leakage and blockage after
every 600 hours of operation or more frequently if neces-
sary.
Flush the cooling system with clean water when filling or
draining the anti-freeze. Close the bottom valve before
opening the cocks.
If flushing is insufficient, remove and clean the inserts in the
heat exchanger, after-cooler and oil coolers. See pages 33
and 34.
Do not use any type of anti-corrosion agent which can da-
mage the light-alloy in the cooling system.
If a fresh water filter (optional equipment) is fitted on the
engine it should be replaced after approximately every 600
hours of operation.
