Use a .040" feeler gauge (or 3/16 drill) under the throttle stop (1/5 of the throttle opening). Connect a 12V test light to the fuse box and the top terminal on the throttle switch. (Good example in Haynes Manual page 124). Light should go out at this adjustment. Solenoid adjustment should be as Bob describes and work smoothly-no binding.

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><br>Bob<br><br><o:p></o:p></p><div><p class=MsoNormal>On 7/1/2023 11:55 AM, John Spaur via Healeys wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Hi All,<o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>My overdrive is functioning again after replacing the accumulator housing and piston but it is exhibiting an odd behavior which I believe is related to the adjustment of the setting lever.<o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>When I open the toggle switch, the OD will sometimes disengage immediately instead of waiting until I blip the accelerator.
