4.20 Engine Cooling System Maintenance
Use a 50/50 water/antifreeze mix in the cooling system all year long. Engine coolant should be replaced every two
years or as needed depending on work hours.
To change the engine coolant, first allow the engine to cool down. Open the valve at the bottom of the ra diator and
drain the radiator coolant into a suitable container. Dispose of the coolant properly. If using a radiator flush
product follow the instructions on the package. After flushing, close the radiator drain valve and refill the radiator
through the fill port on top of the radiator and replace the radiator cap.
IMPORTANT NOTES
:
1.
Check the concentration of the antifreeze with a hydrometer during the winter when temperatures are colder.
If you find that the antifreeze is too weak, it should be replaced. Frozen coolant can cause major problems
and could damage the tractor.
2.
The tractor engine runs on high grade light diesel. Use light diesel fuel No. 1 in the summer and light
diesel fuel No. 2 in the winter. The diesel fuel must be clean and free of water.
3.
Regularly check the lube oil level in the fuel injection pump and fill it when it is low. You should change the
lube oil in the fuel injection pump every 200 working hours. The oil used for the fuel-injection pump should be
30 weight oil.
4.21 Alternator Maintenance
Maintain the alternator every 1000 hours, using the following method:
1.
Check to make sure that the alternator lock nut is tight, that the cable insulation is in good condition and that
the cable connections are sound with no break.
2.
Check the terminals every 1000 hours. If the terminal surface is corroded, clean with sandpaper.
IMPORTANT NOTES:
1.
When starting the tractor, make sure that the radiator is full. Check if there is any leakage and that the
radiator cover is secured.
2.
Check the outside of the radiator regularly to make sure that it is clear of weeds, dust and grease.
