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 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.
