(D) Turn the crankshaft carefully in direction of engine rotation until the piston
touches the piston stoppers.
◆ NOTE: Allways turn the crankshaft in direction of engine rotation, to
move the piston towards the piston stopper.
◆ NOTE: The force applied should be strong enough to break-through
possible accumulations on the piston’s surface.
(E) Turn the protractor (2) on the holder (1) until the pointer of the metal sheet
(3) points to 0° then tighten with screw (5).
◆ NOTE: From this point onwards until the measurement procedure has
ended the protractor must not be turned on the metal sheet.
◆ NOTE: In this position the piston of cylinder 1 touches the piston
stopper.
(F) For a smoother removal of the piston stopper turn the piston slightely away
from the piston stopper.
(G) Now install the piston stopper at cylinder 2 and procede like at cylinder 1.
(H) Read the difference to 0° from the protractor.
