approx. 1.5 bar
YES go to 7 NO go to 8
7
- Replace the oil minimum pressure switch.
8
- If pressure lower than 1.3 - 1.5 bar is measured.
AHEAD go to 9
9
- Replace the oil filter and repeat the pressure check with oil at 80°C.
YES go to 10 NO go to 13
10
- The failure was fixed.
It is recommended to respect the suggested number of kilometres covered.
11
- Check and restore the electrical system.
12
- If pressure lower than 4 bar is measured.
AHEAD go to 9
13
- Remove the flywheel cover and check the by-pass and the cover sealing gasket efficiency towards
the case internal side, as described in the "Flywheel cover" chapter.
YES go to 14 NO go to 15
14
- Check whether there is an irregular clearance on the crankshaft:
- axial clearance (see the "Crankcase and crankshaft" chapter)
- radial clearance, especially in the direction of the cylinder axis
- clearance according to the direction of rotation with the connecting rod in quadrature
YES go to 16 NO go to 17
15
- Replace the faulty components ("Flywheel cover" chapter).
16
- Overhaul the engine ("Crankcase and crankshaft" chapter).
17
- Open the engine crankcase and remove the oil pump, as described in the "Crankcase and crank-
shaft" chapter.
- Check the oil pump as described in the following pages.
- Check that the cooling nozzle and the timing feeding jet are properly installed.
- Visually inspect the crankshaft couplings and their size ("Crankcase and crankshaft" chapter).
N.B.
POTENTIAL IRREGULARITIES IN COUPLINGS AND THE TIMING SYSTEM COMPONENTS CAN-
NOT BE DETECTED WHEN INSPECTING THE LUBRICATION PRESSURE. THEY MAY BECOME
EVIDENT BY AN INCREASE IN NOISE.
N.B.
IN CASE OF IRREGULAR PRESSURE ON THE CRANKCASE, CARRY OUT A VISUAL AND DI-
MENSIONAL INSPECTION OF THE TIMING SYSTEM COMPONENTS (SEE "THERMAL GROUP
AND TIMING SYSTEM" CHAPTER).
Oil pressure check
1
- In case of oil leaks from the oil filter or from the flywheel cover coupling gasket, check the lubrication
pressure.
