5. Connect the oil supply tube fitting to the filter
header. Tighten nut on the tube to the special
torque value (Table 42).
6. Fill oil filter with the proper grade and viscosity of
engine oil. See the DT 466, DT 570 and HT 570
Engine Operation and Maintenance Manual.
7. Lubricate new oil filter gasket with clean engine
oil.
8. Fasten Spin oil filter onto header until the gasket
initially makes contact. Using an Oil Filter Wrench
with a band width of 38 mm (1.5 in) or greater,
(Table 43) tighten filter an additional one full turn.
NOTE: Do not overtighten filter. A damaged filter may
fracture or leak.
9. If not already installed, install coolant drain plug
(M18) and tighten to the special torque (Table 42).
Read all safety instructions in the "Safety Information" section of this manual before doing any procedures.
10. Refill cooling system.

Priming the Lubrication System

Preferred Method
When the engine has been assembled, lubricate the
engine with oil before starting. This will aid internal
components with the proper lubrication requirements
during the critical initial startup phase. The following
procedure is the preferred method to use when
priming the lubrication system.
1. If engine was completely disassembled and
rebuilt, remove the plug assembly (M12) (Figure
404) and pressurize the lubrication system with
sufficient oil to fill the oil filter and charge the
entire lubrication system.
2. Install plug assembly (M12 and tighten to the
special torque (Table 42).
3. Check the oil level before starting engine.

Alternate Method

CAUTION: To prevent engine damage, make sure
that all moving internal components of the engine
have been well oiled during assembly, if using this
procedure.
1. Crank the engine – but do not start the engine
(ensure CMP sensor is disconnected) – until
the oil pressure gauge indicates sufficient oil
pressure.
2. After oil pressure is evident in the lubrication
system, reconnect CMP sensor connector and
start engine.
