Engine Maintenance
ENGINE LUBRICATION SYSTEM
The TK 3.95 diesel engine has a pressure lubrication sys-
tem. Oil is circulated by a trochoid type oil pump driven by
the crankshaft timing gear and has several times the capac-
ity required by the engine. Oil is picked up through a suc-
tion tube with a screened inlet. Oil to the rocker arm shaft
flows through a tube on the outside of the engine and into
the head through a restrictor fitting.
Oil pressure is affected by oil temperature, viscosity and
engine speed. Subnormal oil pressures usually may be
traced to lack of oil, faulty relief valve or worn bearings.
The use of improper viscosity oil will also produce low oil
pressure shutdowns.
Engine Oil Pressure Sensor
Engine oil pressure sensor should rise immediately on start-
ing. If engine oil pressure drops below 10 ± 3 psig (69 ± 21
kPa), the sensor signals the microprocessor to stop the
engine. Refer to Thermoguard µP-IV Microprocessor Con-
troller Operations and Diagnosis Manual (TK 41087).
Engine Oil Change
The engine oil should be changed every 750 hours (1000
hours with bypass filter) or 6 months, whichever occurs
first. Drain the oil only when the engine is hot to ensure that
all the oil drains out. When changing oil, try to make sure
that the trailer is not tipped away from the direction that the
oil is supposed to flow from the oil pan. It is important to
get as much of the residual oil out as possible because most
of the dirt particles are in the last few quarts of oil to drain
out. Refill the pan with 10 quarts (9.5 liters) and check the
dipstick level. Run the unit, and then recheck the oil level.
NOTE: Fill the crankcase slowly so oil will not run into
the breather hose, thus filling up an open cylinder. Leav-
ing the dipstick out while adding engine oil will vent the
crankcase.
Add oil as necessary to reach the full mark. See Specifica-
tions page for correct type of oil.
Oil Filter Change
The oil filters should be changed along with the engine oil.
Spin-on Filters:
1. Remove the filter.
2. Apply oil to rubber ring of new filter and install filter.
3. Tighten the filter until the rubber ring makes contact,
then tighten 1/2 turn more.

CRANKCASE BREATHER
The crankcase breather system ducts crankcase gases
formed in the crankcase directly to the intake elbow. Harm-
ful vapors that would otherwise collect in the crankcase and
contaminate the oil or escape to the outside, are now drawn
back into the engine and burned. The breather hose should
be inspected yearly to make sure it is not plugged.
