Oil Pressure Check - APRILIA MSS Mana GT ABS Service Station Manual

MSS Mana GT ABS
8 - If pressure lower than 1.3 ÷ 1.5 bar is measured.
CONTINUE - point 9
9 - Replace the oil filter and repeat the pressure check with oil at 80°C.
YES - point 10 NO point 13
10 - The failure is fixed.
It is advisable to observe the suggested number of kilometres covered.
11 - Check and restore the electrical system.
12 - If pressure lower than 4 bar is measured.
CONTINUE - point 9
13 - Open the engine crankcase and check the by-pass efficiency.
YES - point 14 NO point 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 - point 16 NO point 17
15 - Replace damaged components.
16 - Overhaul the engine.
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 system supply jet are properly fitted.
- Visually inspect the crankshaft couplings and their size «Specifications Chapter».
NOTE
ANY FAILURES IN THE COUPLINGS AND IN THE TIMING COMPONENTS CANNOT BE DETEC-
TED BY THE LUBRICATION PRESSURE CHECK. THE FAILURES MAY BECOME EVIDENT BY
AN INCREASE OF NOISE.
NOTE
IN CASE OF IRREGULAR PRESSURE ON THE BASE, CARRY OUT A VISUAL AND DIMENSIONAL
INSPECTION OF THE TIMING COMPONENTS (SEE THERMAL GROUP AND TIMING SYSTEM
CHAPTER).
