3.6 ENGINE CHECKS SUBSEQUENT TO
REASSEMBLY
Carefully read 0.4.1 (PRECAUTIONS AND GENERAL
INFORMATIONS).
3.6.1 BLEEDING THE ENGINE OIL CIRCUIT
• Refill the engine with motor oil, see 2.14 (CHANGING
THE ENGINE OIL AND THE OIL FILTER).
• Slip the two electric connectors off the two injectors
(1-2).
• Press the start push button and let the engine run until
the engine oil pressure warning light LED goes out.
• Insert the two electric connectors on the two injectors
(1-2).
• Top up with motor oil until the tank level reaches the
prescribed .lirrut, see .2.1.3 (CHECKING THE .ENGINE
OIL LEVEL AND TOPPING UP).
• Start the engine and let it idle for approx. 10 minutes.
• Check the oil level again and, where necessary, top
up.
3.6.2 CHECKING THE ENGINE OIL PRESSURE
NOTE
Have the appropriate special tool
mil
to hand:
- aprilia part# 8140181 (Fuel - oil pressure gauge) (3).
• Connect the oil pressure gauge (4) in place of the en-
gine oil pressure sensor (3).
Engine oil pressure: min. 50 kPa (O.5 bar).
NOTE
Checktheoil pressure at a temperature ofBO °C
(176 OF) and at a speed of at least 1200 rpm.
If the oil pressure is below the minimum limit, check
the oil pump and relevant drive assembly.
• During reassembly, coat the thread of the engine oil
pressure sensor (3) with LOCTITE® 243.
Engine oil pressure sensor driving torque: 15 Nm (1.5
kgm).
3.6.3 SYNCHRONIZING CYLINDERS
see 4.8.10 (SYNCHRONIZING CYLINDERS).
