･ It is necessary to inspect the gap to determine whether
adjustment is necessary only when installing a new snap-action
unit or an overhauled snap-action unit (from this or another
PowerTrap).
･ The snap-action unit must be installed before the gap inspection can
be carried out. A feeler (go/no-go) gauge to be used in gap inspection
is supplied with each spare snap-action unit. To check the gap,
carefully slide the thin end of the feeler gauge (marked I.V.) into the
gap between the push plate and intake valve (motive medium).
Use this end Feeler Gauge
･ If the gap is already adjusted properly (3 ± 0.3 mm, 0.118 ± 0.012
in), the gauge will stop when the valve contacts the no-go lip.
GO NO-GO
･ The valve is free to move vertically, so be certain to hold the base
of the gauge flush with the push plate, and do not force the
gauge past the no-go lip.
･ When a snap-action unit that has been removed from the cover is
reinstalled without being overhauled, do not loosen the holder
nuts from the push plate.
･ If the previous inspection reveals that the gap is out of the
accepted range (3 ± 0.3 mm, 0.118 ± 0.012 in), proceed with
gap adjustment.
･ Loosen the holder nuts with two 22 mm (

･ Set the position with the upper nut, then finger-tighten the lower
nut.
･ Recheck the gap with the feeler gauge.
･ When adjustment is complete, hold the upper nut steady with the
open-end wrench and tighten the lower nut with the open-end
torque wrench to a torque of 60 N·m (44 lbf·ft).
･ Recheck the gap, and, if necessary, repeat the adjustment
procedure.
