HECK OF THE TIMING SYSTEM SETTING
.
To check the engine timing setting, work as follows:
•
Create a backlash of 1,5 mm between the rockers;
• Unscrew the engine pinion’s fastening nut;
• Fit the hub, Code 65 92 84 00 “2”, onto the engine
shaft slot, having fitted the index plate, Code 19 92 96
00 “3”, and fastening it to the engine shaft by means
of a screw;
• When it is half-screwed down, fasten arrow code 17
94 75 60 “4” to the crankcase threaded hole;
• Fit a dial gauge support “5” onto the LH cylinder’s spark
plug hole. Then fit the gauge into the latter;
• Turn the disk in a clockwise direction until the LH cylinder
piston is at top dead center (with valves closed). Reset
the gauge and make sure that the marks (on the timing
gearing and on the engine pinion) “1” are perfectly
aligned. Look through the inspection hole on the gearbox
housing to make sure that the line with the letter “S” is
perfectly aligned with the mark made on the centre of
the hole;
• At this point align, the tip of the arrow with the “T.D.C.”
zero on the index plate,
• Check the setting according to the timing diagram.
• Tighten the support with dial gauge onto the spark plug
hole on the RH cylinder head;
• Fit the control arrow onto the RH side of the crankcase;
• Turn the disk in a clockwise direction until the “D” marking
is in line with the mark in the center of the inspection
hole on the gearbox housing (valves closed);
• Repeat the same procedures as for the LH cylinder.
Having completed the test and if everything looks correct:
• Restore the operating backlash between the rockers
and the valves (intake 0.10 mm; exhaust 0.15 mm;)
• Remove the index plate from the crankshaft and the
arrow from the crankcase;
• Remove the support together with the dial gauge from
the hole on the cylinder head, refit the spark plug and
complete the assembly.
