Checking Parauelism Of End Axis; Fitting Up Con-Rods On Crankshaft - MOTO GUZZI V-7 700 Operating Handbook

CHECKING PARALLELISM OF END AX IS
Before fitting con-rods, check their", squaring " ,
meaning that the two axis of big and small end
holes must be parallel to each other. Possible
deformations can be eliminated operating on rod
with forked lever (see Fig. 37) .
Maximum permissible offset to the two axis ,
measured at 200 mm. (7.874 " ) is
±
0.03 mm.
(.00118").
FITTING-UP CON-RODS ON CRANKSHAFT
When fitting up con-rods on crakshaft , pay atten-
tion that lubrication ducts in con-rod big ends
are set as follows (see A on Fig . 38) :
Upward , for UH cylinder con-rod
Downward, for Ri H cylinder con-rod
N.B.: Viewing engine from clutch side, number
marked on con-rod big end must match
with number marked on cap. Both num-
bers must be on same side (see Fig . 38).
Bearing-crankshaft pin clearance is 0.011 - 0.061
mm . (.000433 - .0024") (see Fig. 39).

Con-rod-c rankshaft side clearan ce must be 0.3
0.5 mm . (.0118-.0196") [see Fig. 40) .
Fit con- rods on crankshaft and tighten nuts by
means of torque w ren ch at 3.500 Kg
/ m. (25.31
fUbs.). See Fig . 41 Fig 42 shows dismantled con-
rod assembly. As to measurements. refer to Fig.
