5. With the specified air pressure appli€d, push up the
timing plate; the synchronizing piston will pop out
and engage the intake secondary rocker arm.
Visually check the engagement of the synchronizing
prston.
NOTE;
The synchronizing piston can be seen in the gap
between the secondary and primary rocker arms,
With the timing plate engaged in the groove on

NOTE:
. When the timing plate is pushed up, it releases
the timing piston, letting the return spring move
the synchronizing piston to its original position.
7. Replace the intake rocker arms as an assembly if
either does not work correctly,

Piston Rings
End Gap
1.Using a piston, push a new ring into the cylinderbore 15 - 20 mm (0.6 - 0.8 in) from the bottom.
Measure the piston ring end-gap with a feeler gauge:
. lf the gap is too small, check to see if you have
the proper rings for your engine.. lf the gap is too large. recheck the cylinder borediameter against the wear limits on page 7-16,
lf the bore is over the service limit, the cvlinderblock must be rebored.

Replacement
1.Using a ring expander. remove the old piston rings.
Clean all ring grooves thoroughly.
NOTE:
. Use a squared-off broken ring or ring groove
cleaner with blade to fit piston grooves.
o Top ring groove is 1.0 mm (0.039 in)wide.. Second ring groove is 1.2 mm (0.047 in) wide.. Oil ring groove is 2,8 mm (0.11 in) wide.. File down the blade if necessary.
CAUTION: Do noi use a wire blush to clean ringlands. or cut ring lands deepol with cleaning tool.
NOTE: lfthe piston is to be separated from the con-necting rod, do not install new rings yet.
3. Install new rings in the proper sequence and posi-
taon (see page 7-22).
NOTE: Do not reuse old piston rings.
