36 MAINTENANCE AND LUBRICATION
•
After all fuel has been removed from the fuel system, open the filter canister
drain [2] at the bottom of the filter unit. Allow any accumulated water and any
remaining fuel to drain.
•
Rotate the filter canister [3] counterclockwise to release it from the mounted
filter adapter [1].
•
Remove the retainer [4] from the bottom of the threaded rod [6] that holds the filter
element. Pull straight down on the filter element to remove it from the rod.
•
Replace the canister bowl O-ring [7] if there are any signs of damage or
deterioration. Clean any filter debris from the adapter, canister and retainer.
•
Lubricate the O-ring very lightly with clean engine oil and reinstall it in the adapter
groove. Install the new filter element onto the rod and hand-tighten the retainer
onto the rod to hold the filter in place.
•
Reinstall and hand-tighten the canister over the filter element.
•
Close the filter drain.
•
Open the valves on each tank to allow fuel to re-enter the system.
•
Start the engine and check for leaks.
Note: A vapor cloud or hissing sound near the filter indicates a leak.
CAUTION
Use of anything other than genuine MACK/Cummins filters may cause damage
and void the engine warranty.
COOLING SYSTEM
The cooling system plays an important role in overall engine performance by
keeping the engine within the normal operating temperature range - hot enough for
efficient combustion, and cool enough to prevent engine damage from overheating.
Good preventive maintenance practices, along with monitoring cooling system
performance, go a long way in preventing engine damage that could result from
cooling system problems. The maintenance items and tests outlined in this section
should be performed at the intervals specified to ensure optimum performance from
the cooling system.
