DESCRIPTION AND OPERATION
Ports for the V-MAC III oil pressure and oil
temperature sensors are located on this mounting
assembly. Remote oil supply ports are provided
for the turbocharger, EGR valve, J-Tech™ engine
brake, and also to supply oil pressure for other
items such as a turbo unloader, REPTO, a
mechanical oil pressure gauge or a
remote-mounted centrifugal oil filter.

OIL FILTERS
The lubrication system includes a centrifugal oil
filter as well as primary and secondary full-flow
filters (Figure 91). The centrifugal Centri-Max
®
ULTRA or ULTRA PLUS oil filter assembly, which
also includes the oil fill port, is mounted at the top
of the oil filter mounting bracket assembly. Its
location is between and outboard of the two
full-flow, spin-on filters, where it drains internally
through the mounting bracket assembly into the
crankcase.
