EXTERNAL OIL SUPPLY ARRANGEMENT
ASET™ AC ENGINES BUILT DECEMBER 2003
AND PRIOR
This procedure covers external oil supply
arrangements for AC engines built December
2003 and prior. For engines built after December
2003, refer to the procedure which follows this
procedure.
For all ASET™ AC engines produced before
December 2003, the oil supply source for the
EGR valve, J-Tech™ engine brake assemblies
and VTG turbocharger is from the supply port on
top of the oil filter mounting bracket as illustrated
in Figure 416. A No. 10 size line for J-Tech™ or
No. 8 size line for non-J-Tech™ is connected
between this port and the junction block at the left
side of the cylinder heads. Oil is supplied to the
J-Tech™ engine brake assemblies (if equipped)
from this block. A No. 8 size line passes between
the cylinder heads to a second junction block on
the right side of the cylinder head near the EGR
valve. Smaller No. 6 size lines are used to supply
oil to the EGR valve and the turbocharger.
