5. With a teeler gauge (A), measure the clearance
between the gauge body and'the adjusting nut (B)
as shown.
lf the clearance between the gauge body and the
adjusting nut is 0.4 mm (0.02 in.), the pushrod-to-
piston clearance is O mm. However, if the clearance
betvveen the gauge body and the adjusting nut is
0 mm. the pushrod-to-piston clearance is 0.4 mm
(0.02 in.) or more. Therefore it must be adjusted
and rechecked.
Clearance: 0 0.4 mm l0 0.02 in.l
lf the clearance is incorrect, loosen lhe star locknut
{A), and turn the adjuster (B} in or out to adJust.
. Adjust the clearance while the specified vacuum
