Oil Supply Lines Removal
[214 HS, HT & RN]
EXTERNAL OIL SUPPLY ARRANGEMENT
ASET™ AC ENGINES BUILT DECEMBER 2003
AND PRIOR
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 144.
To remove the oil lines, first cut the stainless steel
straps (if so equipped) that secure the lines
together and to any support brackets. Then,
disconnect the oil supply lines from the fittings at
the EGR valve, junction blocks and oil filter
adapter housing. Remove the lines from the
engine.
Avoid contaminating loose oil lines and fittings
when disconnected. Fitting and oil line
cleanliness is very important.
