EMI 3000 air cleaners are NOT interchangeable

used in trailer units.
Engine Lubrication System
The TK486 family of engines use a pressure
lubrication system. Refer to the TK482 and
TK486 Engine Overhaul Manual TK 50136 for a
detailed description of the engine lubrication
system.
Engine Oil Change
The engine oil should be changed according to the
Maintenance Inspection Schedule. Drain the oil
only when the engine is hot to ensure that all the
oil drains out. When changing oil, keep unit and
trailer level so all the oil can flow from the oil
pan. It is important to get as much of the oil out as
possible because most of the dirt particles are
contained in the last few quarts of oil that drain
out of the pan. Refill the pan with 12 quarts
(11.4 liters) and check the dipstick level. Run the
unit, and then recheck the oil level. The engine oil
level should be at the FULL mark with the
dipstick turned (threaded) into the oil pan. Never
overfill. See Specifications Chapter for correct
type of oil.
Oil Filter Change
The oil filter should be changed along with the
engine oil. Use a genuine Thermo King extended
maintenance oil filter.
1. Remove the filter.
2. Apply oil to the rubber ring of the new filter
and install the filter.
3. Tighten the filter until the rubber ring makes
contact, then tighten 1/2 turn more.
4. Start the unit and check for leaks.
