LUBRICATION

Break-in oil

1.  Use one of the following during the 

fi

 rst 100 hours 

of operation:

 

a.  John Deere Engine Break-In Oil

 

b.  API Service CC, CD oil

 c. 

ACEA 

Speci

fi

 cation E1

2. 

Do not use

 John Deere PLUS-50 oil or engine oils 

meeting API CF-4, API CG-4, API CH-4, API 
CI-4, ACEA E2, ACEA E3, ACEA E4,  or ACEA 
E5 performance levels during the 

fi

 rst 100 hours of 

operation of a new or rebuilt engine.  These oils will 
not allow the engine to break-in properly.

Lubrication - General

1.  Use only clean, high quality lubricants stored in 

clean containers in a protected area.

2.  These oils are acceptable after the 

fi

 rst 100 hours:

 

a.  API Service CH-4, CJ-4 multi-viscosity oils.

 

b.  API Service CD/CG-4/CF-4 multi-viscosity oils.

 c. 

ACEA 

Speci

fi

 cation E3

 d. 

ACEA 

Speci

fi

 cation E4/ E5 

3.  Use the proper weight oil for your average operation 

temperature.

4.  Some increase in oil consumption may be expected 

when SAE 5W and SAE 5-20W oils are used. Check 
oil level frequently.

5.  Never put additives or 

fl

 ushing oil in crankcase.

SP1.  CHECK ENGINE OIL LEVEL

1.  Check the oil level in the crankcase, with the oil 

dipstick, daily.

2.  The oil level must be between the “Waf

fl

 ed area” 

and the “Add”. Never allow the level to go below the 
“Add”. 

3.  Always add the same viscosity of oil as is already in 

the crankcase.

SP2. OIL CHANGES

1.  Using the oil recommended above, change the engine oil 

and 

fi

 lter after the 

fi

 rst 100 hours of operation, and every 

250 hours thereafter.

2.  During intermittent cold weather operation, change oil 

every 100 hours or six weeks, whichever comes 

fi

 rst.

3.  Change oil at any seasonal change in temperature when a 

new viscosity of oil is required.

4.  Engine Lube Oil Capacity:

SP3. CHANGING OIL FILTER

1.  Change the lube oil 

fi

 lter every 250 hours.

2. Use a 

fi

 lter wrench to remove old 

fi

 lter. Dispose of 

fi

 lter 

in approved manner.

3.  Make sure the gasket from the old 

fi

 lter is removed and 

discarded.

4.  Lubricate the rubber gasket on the new 

fi

 lter and screw it on 

nipple until gasket meet the sealing surface.

5.  Using hands only, no wrench, tighten 

fi

 lter one-half turn 

farther. Overtightening can do damage to 

fi

 lter housing.

6.  Fill engine with recommended oil.  Start engine and 

check for leakage. Stop engine and check oil level. Add 
additional oil if necessary.

SP4. AIR CLEANER

1.  Inspect air cleaner every 100 hours, clean and re-oil 

every 600 hours, or yearly, or when red service light is 
visible in air 

fi

 lter restriction indicator; whichever comes 

fi

 rst.  Replace 

fi

 lter element after 5 to 7 cleaning cycles, 

depending on condition.  

 

Note:  Use part # 24-20019 Cleaning and Re-Oiling Kit, 
do not use motor oil or other oils to re-oil 

fi

 lter.

 

2.  Replace oil separator 

fi

 lter every 600 hours, or yearly, or 

if oil leakage is seen at crankcase pressure regulator vent; 
whichever comes 

fi

 rst.  

Note:  Air 

fi

 lter element must be 

removed to access retaining clamp and cover that retains 
oil separator 

fi

 lter inside.

3.  Check hoses and clamps on crankcase pressure regulator 

plumbing for tightness, cha

fi

 ng or deterioration. 

4.  Start the engine and check for leaks.

 

NOTE:

  Make absolutely sure no impurities enter the 

engine while changing the element. Do not run the 
engine with the air cleaner removed.
