SECTION 3.3
LUBE OIL FILTER
All engines use full flow oil filters of the "spin on" type ele-
ment. They have a non-replaceable pleated paper cartridge.
Each filter has an integral bypass valve in the event of plug-
ging or for cold start purposes.
NOTE:
Use only appro ved f ilters with the recom-
mended filtration micron rating. See parts list
Section 6 for proper service part numbers.
Replacing Spin on Oil Filter(s)
1. Obtain the Detroit Diesel recommended replacement
lube oil filter. See Chart, Page 44.
2. Use a properly sized oil f
ilter wrench, such as
Kentmoore P/N J24783, and remove filter(s).
3. Discard used filter(s) as recommended by EPA.
4. Clean the f ilter base mounting surf ace with a lint free
cloth.
5. Lightly coat the oil filter seal with clean engine oil.
6. Start threading the ne w replacement f ilter onto the
threaded portion of the base and hand tighted until the
seal contacts the filter head. With the filter wrench, con-
tinue to tighten two-thirds of a turn.
7. Start engine and check for leaks. If any are found do not
put engine into service until corrections are made.
LUBRICATING OIL REQUIREMENTS
Hundreds of commercial oils are mark eted today, but label-
ing terminology differs among suppliers and can be confus-
ing. Some mark eters may claim that their lubricant is suit-
able for all mak es of diesel engines and may list engine
makes and types, including Detroit Diesel, on their contain-
ers. Such claims, by themselves, are insufficient as a method
of lubricant selection for DDFP engines.
The proper lubricating oil for all DDFP engines is selected,
based on SAE Viscosity Grade and API (American
Petroleum Institute) Service Designation. Both of these
properties are displayed in the API Symbol, which is illus-
trated within the specif ic requirements. For DDFP engines,
the proper lubricant must also possess a sulfated ash content
below 1.0% mass.
Lubricating oils for Non-T actical Military usage currently
SAE Viscosity Grade: 40
API Classification: CDII or CF2
Sulfated Ash: less than 1.0%
API Symbol:
*CF-2 when available
specify a Mil-L-2104F type oil. Because the y may display
different viscosity grades, it is necessary to use a SAE 40
grade only.

LUBRICANT REQUIREMENTS
This is the only oil recommended for Detroit Diesel Engines
used in DDFP service. Lubricants meeting these criteria
have provided maximum engine life when used in conjunc-
tion with recommended oil drain and f
ilter maintenance
schedules.
Certain engines operating conditions may require e
xcep-
tions to this recommendation. They are as follows:
1. For continuous high temperature operation (o ver 100° F
38° C Ambient), the use of SAE 50 grade lubricant in all
DDFP engines is recommended.
2. The API Performance Cate gory CF2 represents an en-
hanced level of lubricant performance o ver CD-II cate-
gory which it replaces. Lubricants meeting this new per-
formance level may not be readily available. During this
interim period oils labeled as API CD-II may be used.
3. When the use of High Sulfur Diesel Fuel (greater than
0.5% mass) is una voidable, the use of lubricants with
higher Total Base Numbers (alkalinity) are recommend-
ed. Refer to Fig. 4 for minimum TBN numbers to be
used for normal service.
MAINTENANCE AND SERVICE PROCEDURE
Weekly
1). Check oil level with the engine stopped. Please refer to
"note" listed in Section 3 under oil le
vel dipstick for
proper oil level check.
