Hank, I have the workshop manuals but the Haynes guide may have =
something I am missing so please send it.

I will try resetting the static setting, fine setting it and then the =
throttle switch

Thanks!

John- it is a .040 feeler gauge that goes under the throttle stop- That =
is equivalent to about 1/5 throttle opening. That is to set the throttle =
switch.=20

=20

The 3/16 drill bit is used to "static set" the position of the solenoid =
lever. I agree, that position is not alway ideal. Fine adjustment is =
made at the arm of the solenoid in which you get it to the maximum lift =
and then when it drops it clears the base about 1/32" at the same time =
gently pushing it in toward the casing to make sure it does not bind. =
Solenoid plunger must drop freely. I can send you that page from Haynes =
manual if it helps you to set the throttle switch. Hank

I think I understand now.

I need to loosen the arm on the throttle switch, put a 3/16 spacer under =

out and then tighten everything up.

Correct?

Bob's got the procedure.  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. Hank

Hi John,

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.

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.

Hi All,

My overdrive is functioning again after replacing the accumulator =

Do I need to fiddle with the setting lever adjustment some more? If so, =

Any other thoughts?

John, to temporarily simplify things you may want to consider taking the =
throttle switch out of the circuit until you get it working properly.  =
Simply connect the two terminals on it with a short wire.  This means =
the O/D will engage/disengage instantly (hopefully) and so you want to =
treat the O/D like another gear and use the clutch to take the strain =
off it.  Given the cost of rebuilding an O/D, using the clutch when =
engaging/disengaging is a good thing to do anyhow just to preserve it.  =
It is probably not a popular thing to do, but the throttle switch was =
disconnected when I bought my BT7 49 years ago.  I connected it up once =
but did not like it and disconnected it again by putting a short loop of =
wire between the terminals.  I just treat the O/D like another gear and =
use the clutch.  Just personal preference.

(hopefully) and so you want to treat the O/D like another gear and use =
the clutch to take the strain off it.=C2=A0 Given the cost of rebuilding =
an O/D, using the clutch when engaging/disengaging is a good thing to do =

do, but the throttle switch was disconnected when I bought my BT7 49 =

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 =

theoretically preventing reverse thrust from damaging the O/D. The =

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 =
