MODEL 152 HANDLING, SERVICE
& MAINTENANCE
1 July 1978 8-11
SAE 20 below -12°C (10°F)
MIL –L-22851 Ashless Dispersant Oil: This oil must be used after the first 50 hours or oil
consumption has stabilized.
SAE 40 or SAE 50 above 16°C (60°F)
SAE 40 between -1°C (30°F) and 32°C (90°F)
SAE 30 between -18°C (0°F) and 21°C (70°F)
SAE 30 below -12°C (10°F)
CAPACITY OF ENGINE SUMP – 6 Quarts
Do not operate on less than 4 quarts. To minimize lass of oil through the breather, fill to 5
quarts for normal flights of less than 3 hours. For extended flight, fill to 6 quarts. These
quantities refer to oil dipstick readings. During oil and oil filter changes, one additional quart is
required when the filter element is changed.
OIL AND OIL FILTER CHANGE
After the first 25 hours of operation, drain engine oil sump and clean the oil pressure screen. If
an oil filter is installed, change the filter at this time. Refill sump with straight mineral oil and
use until a total of 50 hours has accumulated or oil consumption has stabilized: then change
to dispersant oil.
On airplanes
not equipped with an oil filter, drain the engine oil sump and clean the oil
pressure screen each 50 hours thereafter.
On airplanes
which have an oil filter, drain the engine oil sump and clean the oil pressure
screen each 50 hours thereafter.
Change engine oil at least every 6 months even though less than the recommended hours
have accumulated. Reduce the intervals for prolonged operation in dusty areas, cold climates,
or when short flights and long idle periods result in sludging conditions.
NOTE
During the first 25-hours oil and filter change, a general inspection of he
overall engine compartment is required. Items which are not normally
checked during a preflight inspection should be give special attention.
Hoses, metal lines and fittings should be inspected for signs of oil and fuel
leaks, and checked for abrasions, chafing, security, proper routing and
support, and evidence of deterioration. Inspect the intake and exhaust
systems for cracks, evidence of leakage, and security of attachment.
Engine controls and linkages should be checked for freedom of movement
through their full range, security of attachment and evidence of wear.
Inspect wiring for security and chafing, burning, defective insulation, loose
or broken terminals, heat, deterioration, and corroded terminals. Check
