Fred, the solenoid will stay engaged when the switch is turned off until you
accelerate beyond about 1? of pedal movement. The bolts on the overdrive
adjustment are 7/16 or a 1/4 British which are almost the same size.

Subject: [Healeys] Overdrive
While the subject of overdrives is being discussed, I have come across ongoing
problems with the overdrive of my 66BJ8.
The overdrive is filled with 30 WT non-detergent oil and after running the
engine, for about an hour, with all 4 corners on jack stands, the trans oil
level is spot on the line between "low" and "high".
Now for the problems;
1. The overdrive does not disengage when turned off. The hole in the lever on
the right side of the trans lines up with the hole in the case when the OD is
activated.
2. When I turn the solenoid power off, the solenoid lever does not fall from
the engaged position. I suspect the lever may be pushed against the trans case
and the friction does not allow the lever to drop down. When I move the lever
by hand, it is not loose, it requires some pressure to get it to move. The
solenoid does not have a problem lifting the lever when I apply power.
3. I cannot get a wrench to fit the pinch bolt to release the lever from the
valve operating shaft. What size nut/bolt "should the pinch bolt be?
3. The solenoid does not release when the dash or ignition switch is turned
off, (checked with a volt meter). What could still be sending power to the
solenoid? What electrical part should I check first and how?
I have been struggling with trying to resolve this OD problem on and off during
the winter and as the weather is now getting nice, I would like to get this
resolved.
Help!!!!
