Engine
139 9821/7850-2 139
Engine
General
Clean
Warning! Airborne particles of light combustible material such as straw, grass, wood shavings, etc. must
not be allowed to accumulate within the engine compartment or in the propshaft guards (when installed).
Examine these areas frequently and clean at the beginning of each work shift or more often if required.
Before opening the engine cover, make sure that the top is clear of debris.
Notice: The engine or certain components could be damaged by high pressure washing systems; special
precautions must be taken if the engine is to be washed using a high pressure system. Ensure that the
engine air intake, alternator, starter motor and any other electrical components are shielded and not directly
cleaned by the high pressure cleaning system.
Notice: Clean the engine before you start engine maintenance. Obey the correct procedures.
Contamination of the fuel system will cause damage and possible failure of the engine.
Stop the engine and allow it to cool for at least one hour. Do not attempt to clean any part of the engine while
it is running.
Do not aim the water jet directly at oil seals or electrical and electronic components such as the ECU (Electronic
Control Unit), alternator or fuel injectors.
Before carrying out any service procedures that require components to be removed, the engine must be
properly cleaned.
Cleaning must be carried out either in the area of components to be removed or, in the case of major work, or
work on the fuel system, the whole engine and surrounding machine must be cleaned.
1. Remove the undershield.
Refer to: Maintenance > Access Apertures > Undershield (Page ).
2. Make sure that the electrical system is isolated.
3. Make sure that all electrical connectors are correctly coupled. If connectors are open fit the correct caps
or seal with water proof tape.
4. Cover the alternator with a plastic bag to prevent water ingress.
5. Seal the engine air intake, exhaust and breather system.
6. Make sure that the oil filler caps and dipstick are correctly installed.
7. Use a low pressure water jet and brush to soak off caked mud or dirt.
8. Apply an approved cleaning and degreasing agent with a brush. Obey the manufacturers instructions.
9. Use a pressure washer to remove the soft dirt and oil. Do not place the jet nozzle closer to any part of the
engine than the distance specified.
Distance: 600mm
10. When the pressure washing is complete move the machine away from the wash area, or alternatively, clean
away the material washed from the machine.
11. Before working on specific areas of the engine use a compressed air jet to dry off any moisture. When the
area is dry use a soft clean brush to remove any sand or grit particles that remain.
12. When removing components be aware of any dirt or debris that may be exposed. Cover any open ports
and clean away the deposits before proceeding.

Oil
Check (Leaks)
Before you start the product, do a check for oil leaks:
1. Make the product safe.
Refer to: Maintenance > Maintenance Positions (Page 124).
2. Get access to the engine compartment (if applicable)
Refer to: Maintenance > Access Apertures (Page 130).
3. Check the engine and the area below for oil leaks.
4. Close the engine cover (if applicable).
5. If necessary, contact your JCB dealer.
Check (Level)
Notice: Do not exceed the correct level of engine oil in the sump. If there is too much engine oil, the excess
must be drained to the correct level. An excess of engine oil could cause the engine speed to increase
rapidly without control.
1. Make the product safe.
Refer to: Maintenance > Maintenance Positions (Page 124).
2. Wait for the oil to drain back into the engine sump before you take a reading. If not, a false low reading
may be recorded which can cause the engine to be overfilled.
3. Get access to the engine compartment (if applicable).
Refer to: Maintenance > Access Apertures (Page 130).
4. Remove and clean the dipstick.
Refer to: Maintenance > Service Points (Page 127).
5. Replace the dipstick.
6. Remove the dipstick.
7. Check the oil level. The oil should be between the two marks on the dipstick.
8. If necessary, add more oil:
8.1. Remove the filler cap.
Refer to: Maintenance > Service Points (Page 127).
8.2. Add the recommended oil slowly through the filler point
Refer to: Technical Data > Fluids, Lubricants and Capacities (Page 184).
8.3. Replace the dipstick.
8.4. Remove the dipstick.
8.5. Check the oil level, if necessary add more oil.
9. Maintenance
Engine

Notice: Do not exceed the correct level of engine oil in the sump. If there is too much engine oil, the excess
must be drained to the correct level. An excess of engine oil could cause the engine speed to increase
rapidly without control.
Warning! Hot oil and engine components can burn you. Make sure the engine is cool before doing this job.
Used engine crankcase lubricants contain harmful contaminants. In laboratory tests it was shown that used
engine oils can cause skin cancer.
Caution! It is illegal to pollute drains, sewers or the ground. Clean up all spilt fluids and/or lubricants.
Used fluids and/or lubricants, filters and contaminated materials must be disposed of in accordance with
local regulations. Use authorised waste disposal sites.
1. Make the machine safe.
Refer to: Maintenance > Maintenance Positions (Page 124).
2. Get access to the engine compartment.
Refer to: Maintenance > Access Apertures (Page 130).
3. Remove the oil filler cap.
Refer to: Maintenance > Service Points (Page 127).
4. Remove the engine oil drain plug. Drain the oil in to a suitable container.
Refer to: Maintenance > Service Points (Page 127).
5. Clean the drain plug. Install the drain plug. Tighten the drain plug to the correct torque value.
Refer to: Technical Data > Torque Values (Page 189).
6. Remove the cap from the oil filter housing (if applicable).
7. Remove and discard the oil filter cartridge.
8. Fit a new filter with new gaskets.
9. Fit and tighten the cover on the oil filter housing (if applicable). Tighten the cover to the correct torque value.
Refer to: Technical Data > Torque Values (Page 189).
10. Add the correct specification and quantity of oil.
Refer to: Technical Data > Fluids, Lubricants and Capacities (Page 184).
11. Check the oil level.
Refer to: Maintenance > Engine > Oil > Check (Level) (Page 140).
12. Install the oil filler cap.
13. Close and secure the engine cover.
14. Operate the engine at idle speed until the oil pressure low warning light has extinguished and the new filter
has primed before the engine speed is increased above idle speed.
15. Check for leaks.
16. Check the oil level when the oil has cooled.
16.1.Fill with clean engine oil, if necessary.

3. Remove the FEAD belt cover.
4. Inspect the belt for cracks, fraying or missing pieces. If necessary contact your JCB dealer for service
requirements.
5. When maintenance is complete, make sure that the guard is installed. Do not operate the machine unless
the guard is installed correctly.
Refer to: Maintenance > Service Points (Page 127).
