removed before installing the new filter.
Install
Use the correct oil filter.
See the Cummins®/Fleetguard®/Nelson filter
specifications for the correct oil filter part number.
CAUTION
The lack of lubrication during the delay until the filter
is pumped full of oil at start-up can damage the
engine.
Use clean 15W-40 oil to coat the gasket surface of the
filter.
Fill the filter with clean 15W-40 oil.
Apply a light film of lubricating oil to the gasket sealing
surface before installing the filter.
NOTE: Be careful that no debris is poured into the filter. If
using an oil supply with a metallic or plastic seal under the
cap, be careful to peel the seal back. Puncturing the seal
with a knife or sharp object can create debris in the oil
container.
CAUTION
Mechanical overtightening of filter can distort the
threads or damage the filter element seal.
Install the filter on the oil filter head. Tighten the filter until
the gasket contacts the filter head surface.
Tighten 3/4 to 1 turn after the gasket makes contact with
the filter head.
