Engine Lubrication System
The TK486 family of engines use a pressure lubrication
system. Refer to the TK482 and TK486 Engine Overhaul
Manual (TK 50136-2-OM) for a detailed description of
the engine lubrication system.
Engine Oil Change
The engine oil should be changed according to the
Maintenance Inspection Schedule.
1.
Drain the oil only when the engine is hot to verify
that all the oil drains out.
2.
When changing oil, keep unit and trailer level so all
the oil can flow from the oil pan.
N
No
otte
e:: 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.
3.
Refill the pan with oil and check the dipstick level.
The new oil filter must also be filled with oil before
it is installed, therefore use a total of approximately
13 quarts (12.3 liters/litres) to fill the oil filter and
refill the pan.
4.
Run the unit, and recheck the oil level.
5.
The engine oil level should be at the FULL mark
with the dipstick turned (threaded) into the oil pan.
Never overfill.
6.
See Specifications 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. Fill the new oil filter with clean engine oil.
3. Apply oil to the two inner O-rings of the new filter
and install the filter.
4. Hand tighten the filter until it seats firmly. The
exposed dust seal ring, if equipped, does not need
to be compressed.
5. Start the unit and check for leaks.
Low Oil Pressure
Oil pressure is affected by oil temperature, oil viscosity,
and engine speed.
•
Low oil pressure can usually be traced to the lack of
oil, a faulty oil pressure regulating valve, or worn
bearings.
•
Low oil pressure is not normally caused by a faulty
oil pump.
•
Use the “Low Oil Pressure Flow Chart” (
) to help diagnose low oil pressure.
