Monitoring the Two-Filter Fuel System Filters
The engine is equipped with a prefilter that filters down to 100 microns, a
coalescer/final filter that separates water, and filters down to 3 to 5 microns. When
servicing these elements, all two filters should be changed at the same time. All
two elements are located within the fuel filter module located on the left side of the
engine.
NOTICE: Do not over-tighten the water drain valve. Failure to properly
tighten the water drain valve may cause damage to the water drain valve
and housing.
NOTE: Filter change intervals may be shortened to conform with
established preventive maintenance schedules, but should never be
extended.
1. Replace the fuel filters using the Preventative Maintenance Tables.
Adjusting the Valve Lash
NOTE: Proper valve lash clearance allows the engine to produce the best
possible performance with the lowest emissions. Valve lash adjustments
should be performed by an authorized Detroit™ maintenance or repair
facility.
Perform a valve lash adjustment as scheduled for the appropriate engine duty cycle.
Monitoring the Belt Tensioner
DD Platform engines are equipped with an automatic tensioning device. No
