Engine Oil Circuit

Engine Oil Circuit Description

Oil is collected from the sump and is drawn through a mesh strainer into the oil pump rotor. The oil pump is fitted with a single pumping rotor which supplies pressurised oil to the lubrication circuit via the oil pressure relief valve. The relief valve is set to open at 5.1 bar (75 Ib/in 2) and when open, returns high pressure oil direct to the sump.

Pressurised oil is delivered to the oil to water heat exchanger (mounted on the front of the engine), where it is cooled.

The cooled oil is then delivered to the outside rim of the oil filter, where it is filtered by passing through the filter membrane. Filtered oil is then fed into the lower crankcase gallery. From here it is distributed around the engine:

• Oil is delivered to the crankshaft main bearings and, via drillings in the crankshaft, to the big end bearings.
• Spray lets located in the upper crankcase, behind the main bearing shells, lubricate the pistons and connecting rod small ends. These jets are fed oil from the crankshaft oil feed. A low oil pressure warning light switch is also located in the upper crankcase gallery.
• Some oil is sent directly to the cylinder head via an internal gallery. Oil that arrives at the cylinder head is fed to both cams via a gallery in the cylinder head casting that delivers oil directly to the sprocket end of the camshafts. Oil is then fed through the hollow camshafts to the other camshaft bearings, the tappet buckets and the valves.
• Oil is fed to the gearbox via internal oil pipes and drillings that supply oil directly to the end of each shaft. Oil is circulated along the gearbox shafts to exit holes that feed directly to the bearings, gears and selectors.

On the Daytona 675, Street Triple and Street Triple R, oil is also fed to the alternator to aid cooling of the alternator components. The oil is taken from the crankshaft oil feed and directed to the alternator via a jet, located above the alternator rotor, in the upper crankcase.

Heat Exchanger

The heat exchanger is used to transfer heat from the engine oil into the coolant. Oil is delivered to the heat exchanger via a hollow centre bolt, after which it flows around the end tank and into the heat exchanger core, where it is circulated.

Coolant is pumped around the outside of the heat exchanger core to cool the oil. The cooled oil then exits the heat exchanger and flows to the oil filter. An additional benefit of the heat exchanger is that, as the engine coolant reaches its operating temperature more quickly than the engine oil, the oil is heated by the engine coolant at lower engine temperatures; this allows the engine oil to reach its optimum operating temperature more quickly, thereby helping to improve engine oil life, reduce exhaust emissions and reduce engine wear.

Engine Oil

Specification

Use semi or fully synthetic 10W/40 or 15W/50 motorcycle engine oil which meets specification API SH (or higher) and JASO MA, such as Mobil 1 Racing 4T.

Caution: Triumph high performance fuel injected engines are designed to use semi or fully synthetic motorcycle engine oil which meets specification API SH (or higher) AND JASO MA.

Do not add any chemical additives to the engine oil. The engine oil also lubricates the clutch and any additives could cause the clutch to slip.

Do not use mineral, vegetable, non-detergent oil, castor based oils or any oil not conforming to the required specification. The use of these oils may cause instant, severe engine damage.

Ensure no foreign matter enters the crankcase during an oil change or top-up.

Triumph Engine Oil

Your Triumph Motorcycle is a quality engineered product which has been carefully built and tested to exacting standards. Triumph Motorcycles are keen to ensure that you enjoy optimum performance from your machine and with this objective in mind have tested many of the engine lubricants currently available to the limits of their performance.

Mobil 1 Racing 4T consistently performed well during our tests and has become our primary recommendation for the lubrication of all current Triumph motorcycle engines.

Mobil 1 Racing 4T, specially filled for Triumph, is available from your authorised Triumph dealer.

Oil Level Inspection

In order for the engine, transmission, and clutch to function correctly, maintain the engine oil at the correct level, and change the oil and oil filter in accordance with scheduled maintenance requirements.

Warning: Motorcycle operation with insufficient, deteriorated, or contaminated engine oil will cause accelerated engine wear and may result in engine or transmission seizure.

Seizure of the engine or transmission may lead to loss of motorcycle control and an accident.

1. Start the engine and run at idle for approximately five minutes.

2. Stop the engine, then wait for at least three minutes to allow the oil to settle.

3. Remove the dipstick, wipe clean and screw fully home in the crankcase.

1. Filler
2. Dipstick location in crankcase
3. Dipstick
4. Upper marking
5. Lower marking

Note:

• The actual level is indicated when the motorcycle is level and upright, not on the side stand, and when the filler has been screwed fully home.
• Do not add oil through the dipstick hole in the crankcase.

4. Remove the dipstick.

5. The oil level is indicated by lines on the dipstick.

When full, the indicated oil level must be level with the upper marking on the dipstick.

6. If the oil level is too low, remove the filler plug and add oil a little at a time through the filler plug hole in the clutch cover, until the correct level is reached.

7. Once the correct level is reached, fit the dipstick and the filler plug.

Oil and Oil Filter Change

Warning: Prolonged or repeated contact with engine oil can lead to skin dryness, irritation and dermatitis. In addition, used engine oil contains potentially harmful contamination which can cause cancer. Wear suitable clothing and avoid skin contact.

The engine oil and filter must be replaced in accordance with scheduled maintenance requirements.

1. Warm up the engine thoroughly, and then stop the engine.

2. Daytona 675 only: Remove the lower fairings.

3. Place an oil pan beneath the engine.

Warning: The oil may be hot to the touch. Contact with hot oil may cause the skin to be scalded or burned.

4. Remove the oil drain plug.

1. Oil drain plug
2. Oil filter

5. With the motorcycle on level ground, and on the sidestand, allow the oil to completely drain.

6. Unscrew and remove the oil filter using Triumph service tool T3880313.

1. Oil filter
2. Tool T3880313

7. Discard the oil filter.

8. Apply a smear of clean engine oil to the sealing ring of the new oil filter.

9. Fit the oil filter and tighten to 10 Nm using Triumph service tool T3880313.

10. After the oil has completely drained out, fit a new sealing washer to the drain plug. Fit and tighten the plug to 25 Nm.

11. Fill the engine with new oil of the type and grade listed previously and in the specification section.

12. Start the engine and allow to idle.

Caution: Racing the engine before the oil reaches every part can cause engine damage or seizure.

13. Ensure that the oil pressure warning light extinguishes shortly after starting.

Caution: If the engine oil pressure is too low, the low oil pressure warning light will illuminate. If this light stays on when the engine is running, stop the engine immediately and investigate the cause. Running the engine with low oil pressure will cause engine damage.

14. Stop the engine and check the oil level. Adjust if necessary.

15. Daytona 675 only: Refit the lower fairings.

Disposal of Used Engine Oil

To protect the environment, do not pour oil on the ground, down sewers or drains, or into water courses.

Dispose of used oil sensibly. If in doubt contact your local authority.

Installation

Caution: Before fitting the oil pump to the crankcase ensure the pump internal surfaces have been 'wetted' with clean engine oil. The pump may fail to pick-up oil from the sump if the surfaces have not been 'wetted'. This will cause the engine to run without engine oil pressure and will lead to severe engine damage.

3. Position the oil pump to the crankcase and insert the water pump inlet sleeve into the opening in the crankcase.

4. Fit the oil pump to the crankcase, ensuring the oil pump dowel correctly locates into the bolt hole in the crankcase.

Caution: Do not use excessive force to insert the dowel into the crankcase. Severe dowel or crankcase damage may result from the use of excessive force.

5. Using a suitable pin punch, gently tap the dowel downwards into the crankcase until it seats.
