Selecting the base gasket
CAUTION
NEVER REUSE A GASKET BASE OF REMOVED CYLINDERS.
ALWAYS INSTALL A NEW ONE.
TO FACILITATE THE INSTALLATION, grease THE INTERNAL SURFACE OF THE CYLINDER
WITH RECOMMENDED ENGINE OIL.
IN CASE THAT HAVE BEEN REPLACED THE PISTON OR THE CYLINDER, IT IS NECESSARY TO
CALCULATE THE THICKNESS OF THE NEW GASKET TO BE INSTALLED, TO ESTABLISH THE
REPORT OF APPROPRIATE COMPRESSION.
MEASURE WITHOUT PLACING GASKETS BETWEEN CYLINDER AND DIAL GAUGE.
NOTE
MAKE SURE THAT THE COMPARATOR DOOR IS PROPERLY FITTED TO THE STUD BOLTS, TO
AVOID POSSIBLE CLEARANCES THAT CAN DELETE THE MEASURE.
CALCULATION OF THE BASE GASKET

special tool AP8140266.
•
Connect the dial gauge on a flat sur-
face and adjust it to point zero.
•
Place the piston to the top dead center
