Cessna 150J - Special Inspection Items; Lubrication

SPECIAL INSPECTION ITEMS
First 25 hours: Refill with straight mineral oil (non-detergent) and use until a total of 50 hours
have accumulated or oil consumption has stabilized, then change to ashless dispersant oil. Change
oil each 50 hours if engine is NOT equipped with external oil filter; if equipped with external oil
filter, change filter element each 50 hours and oil at each 100 hours; or every 6 months.
2 Clean filters per paragraph 2-22. Replace as required.
3 Replace hoses at engine overhaul or after 5 years, whichever comes first.
4 General inspection every 50 hours. Refer to Section 11 for 100 hour inspection.
5 Each 1000 hours, or to coincide with engine overhauls.
6 Each 50 hours for general condition and freedom of movement. These controls
are not repairable. Replace as required at each engine overhaul.
7 Each 500 hours.
8 INTERNAL TIMING: These magnetos cannot be overhauled or timed in the field.
The coil, capacitor and breaker assembly are non-replaceable. As a good main-
tenance practice, and to have the benefit of good ignition at all times, it is
recommended that the magnetos be removed at 900 hours of magneto time, and
install new exchange magnetos.
MAGNETO-TO-ENGINE TIMING: First 50 hours, first 100 hours and each 200
hours thereafter.
9 First 100 hours and each 500 hours thereafter. More often if operated under
prevailing wet or dusty conditions.
10 Replace each 500 hours.
11 Check electrolyte level and clean battery compartment each 50 hours or
each 30 days.
12 Refer to Section 16 of this Manual.
13 Lubrication is required of the actuator each 1000 hours and/or 3 years,
whichever comes first. Refer to figure 2 -5 for grease specification.
Refer to Section 9 of this Manual for free-play limits, inspection, re-
placement and/or repair.
14 Refer to paragraph 2-44 for detailed instructions for various serial ranges.
NOTE
A
high-time inspection is merely a 100-hour inspection with the addition
of an engine overhaul. Continental recommends engine overhaul at 1800
hours for the 0-200-series engine, except as stipulated in Continental
aircraft engine Service Bulletin #M74-20 and supplements thereto. At
the time of overhaul, engine accessories should be overhauled.
