We want to teach you all about engine oil to help your tractor run better and last longer.
If you do not feel that you understand these tips, steps, and strategies, or can perform them safely, consult your tractor dealer or local mechanic.
NOTE: There are a few important things to know before servicing your oil.
Here are a few:
Only use the engine oil specified. Other engine oils may affect warranty coverage, cause internal engine components to seize, and/or shorten engine life.
Never overfill the oil. Overfilling may result in white exhaust smoke, engine overspeed, or internal damage.
Prevent dirt and debris from contaminating the engine oil. Carefully clean the oil cap/dipstick and the surrounding area before you remove the cap.
Never mix different types of engine oil. This may adversely affect the lubricating properties of the engine oil.
Engine Oil Specifications
Use an engine oil that meets or exceeds the following guidelines and classifications.
API service categories CD, CF, CF-4 and Cl-4
ACEA service categories E-3, E-4, and E-5
JASO service category DH-1
API classification (American Petroleum Institute)
ACEA classification (Association des Constructeurs Europeens d'Automobilies)
JASO (Japanese AutomobileStandards Organization)
Note all the following:
Be sure the tractor engine oil, engine oil storage containers, and engine oil filling equipment, are free of sediments and water.
Change the engine oil after the first 50 hours of operation, and then every 250 hours thereafter.
Select the oil viscosity based on the ambient temperature where the engine is being operated. See the SAE service grade viscosity chart.
YANMAR does not recommend the use of engine oil "additives."
Additional Technical Engine Oil Requirements
The engine oil must be changed when the Total Base Number (TBN) has been reduced to 1.0 (mgKOH/g) test method; JIS K-201-5.2-2 (HCI), ASTM D4739 (HCI).
Engine Oil Viscosity
Select the appropriate engine oil viscosity based on the ambient temperature and use the SAE service grade viscosity chart.
Checking Engine Oil:
1. Make sure the engine is level.
2. Remove the dipstick (Figure4-6, (1)) and wipe it with a clean cloth.
3. Fully reinsert the dipstick.
4. Remove the dipstick. The oil level should be between upper (Figure 4-6, (2)) and lower (Figure 4-6, (3)) lines on the dipstick.
5. Fully reinsert the dipstick.
Adding Engine Oil:
1. Make sure the engine is level.
2. Remove the oil cap (Figure 4-6, (4)).
3. Add the indicated amount of engine oil at the top or side engine oil filler port (Figure 4-6, (5)).
4. Wait three minutes and then check the oil level.
5. Add more oil if necessary.
6. Replace the oil cap (Figure 4-6, (4)) and hand-tighten. Over-tightening may damage the cap.
Engine Oil Capacity (Typical)
Note: These are the engine oil capacities associated with a "deep standard" oil pan. Oil capacity will vary depending upon which optional oil pan is used. Refer to the operation manual provided by the driven machine manufacturer for the actual engine oil capacity of your machine.
The following are the engine oil capacities for various YANMAR TNM and TNV engines:
