Hi John,<br>
<br>
What keeps the O/D from disengaging immediately when you open the
dash switch is the 'throttle switch.' When the O/D is actuated there
is a parallel circuit that will keep the O/D activated until you
press the accelerator pedal, theoretically preventing reverse thrust
from damaging the O/D. The parallel circuit runs through the
throttle switch on the scuttle (firewall); it sounds like you need
to adjust it. It's a simple adjustment using a certain diameter--I
don't recall it offhand, but I'll look it up if you need it--drill
bit under the throttle stop levers. There's a small shaft off the
throttle mechanism that opens this switch--it's just a set of points
and a cam inside--with a lever with a pinch clamp. Just loosen the
pinch clamp, set the bit under the throttle stop plate and tighten
the clamp.<br>
<br>
If you O/D is actuating consistently within a couple seconds or so
then your solenoid, operating lever, operating shaft and ball
'valve' are correct. The
'stick-a-drill-bit-through-the-lever-into-the-housing' method is
notoriously unreliable; the proper setting is best achieved by
measuring the lift--IIRC, it's 1/32" but not sure--of the operating
shaft at the top of the O/D hydraulic section. <br>

replacing the accumulator housing and piston but it is

<p class="MsoNormal">When I open the toggle switch, the OD will
sometimes disengage immediately instead of waiting until I
blip the accelerator. When I adjusted the setting lever, I
could not use a 3/16” dowel to line up the lever with the hole
in the housing. I had to advance the lever clockwise a bit to
get the OD to engage when the toggle switch was closed. This
has always been the case and this issue is mentioned in some
articles.<o:p></o:p></p>
