•
Rotate the crankshaft up to the TDC
(the reversal point of the dial gauge ro-
tation).
•
Lock the crankshaft at TDC using the
specific tool.
•
Calculate the difference between the
two measurements: using the chart be-
low, identify the thickness of the cylin-
der base gasket to be used upon
refitting. By correctly identifying the cyl-
inder base gasket thickness, an ade-
quate compression ratio can be main-
tained
•
Remove the specific tool and the cyl-
inder.
