APRILIA RSV4 R User Manual

There are no dimension classes for the pistons.
Preassemble the pistons on the workbench with
the connecting rod shank and the relative semi-
bushing.
The pre-assembly procedure is identical for all four
pistons and must be done as follows:
•
with the piston crown parallel to the
workbench and the arrow (1) posi-
tioned from the side opposite of the
operator, fit the connecting rod shank
with the bevelling (2), on the hole of the
rod head, on the right side.
•
Position the special tool on the crank-
case.
•
Partially insert the connecting rod
shank - piston assembly in the corre-
sponding cylinder with the arrow (on
the piston) twisted 45°towards the ex-
haust.
•
When the connecting rod head is low,
and has exceed its lubricating jet, ro-
tate the connecting rod shank - piston
assembly with the arrow on the piston
crown towards the exhaust; the bevel-
ling on the connecting rod head must
face outward of its crank pin.
