Well M-Man....you seem like someone I need to talk to with your experience.
I received the solenoid yesterday, put it on the bench and applied 12v to it. The plunger did not move. I tugged slightly on it by hand and it engaged. I called JPinto and he told me that it is supposed to operate like this. He said that I need to adjust the cable to be pulling slightly on the plunger when it's bolted in place. Is this right? This doesn't seem right to me.
I will check to see if the cable adjustment controls how the plunger sits in there but I don't think it does.
JPinto charged me $307 for the rebuild
So, I just got home and the cable/linkage does not affect the depth of the retainer for the solenoid shaft.
Now....what do I do (assuming the solenoid isn't right)? JPinto is telling me that it is right and unless I'm way off here, it seems that something is not right...
So, I'm still in here working on it and found that the blue and red wire to the relay were backwards. Also, the relay rivets to the fuse holder had to be pinged with a punch and hammer because they were loose causing a bad connection. As for the solenoid....I was bench testing it improperly.
Looking at your drawing posted here on Fordification, I realized that wire 104 is for when you go into passing gear through the bypass switch which kills the ignition for approximately one revolution of the crankshaft. I was trying to use that as ground....wrong.
So, when I bench tested the solenoid using the male of the solenoid's connector and the casing of the solenoid to ground, it worked perfectly.
I Just took the truck on the street and overdrive worked perfectly. The speed sensor doesn't engage until approx 40 mph, but that's fine....IT WORKS!

Congratulations. ODs are NOT that difficult to trouble shoot the only real problem is that so few people are familiar with them. Including how they are SUPPOSED to work! (which is why I wrote that article)
If the governer is activating the relay (by simply grounding it out) at a speed above 28 MPH (which is when it is supposed to operate) then there is a mismatch of 'speedometer' gears.
The governor is driven from the same transmission output shaft gear that drives the speedometer. In order for a speedometer to be accurate the speedometer drive gear and driven gear must be matched to the REAR AXLE ratio.
Did the rear axle ratio get changed somewhere along the line?
If the OD (relay) doenst engage until 40MPH it seems like the third member may have been changed to a higher ratio. (lower numerically) OR the tires/wheels were swapped to a larger overall diameter. This can be corrected by changing the driven gear on the governor.
OD vehicles were originally delivered with VERY LOW ratios. They functioned because the OD is a 0.7 ratio. Wanna know the final drive in OD? multiply the rear axle ratio by 0.7.

Wow....definitely a nice write-up! I must have missed you posting it, but I'd be glad to add it to the tech articles. I'll PM you.

'67 F-100 2WD SWB ~ '69 F-100 4WD SWB w/7" chop ~ 1975 F-250 Ranger XLT Supercab Camper Special My '67 restoration video -> Posting and you!<-a MUST watch for all!!
I went drive the truck again today and it engages between 30 and 35 mph...probably closer to 35 mph.
The tires may not be stock size...235/75/15?
Either way....it's working extremely smooth and it's a pleasure to drive. Passing gear is working perfectly as well
Again.....thank you very much.
I will tell the owner to keep this site in mind for future information. Unfortunately, this is not my truck. I've been working on it since April 08 doing a complete restore. I contacted the owner last night notifying him that it was complete!
The wires to the solenoid are all cut and it seems that it was hit by something. I removed the cover and there's bits missing inside. I think the part that's missing is the switch which changes between the "actuate" coil and the "hold" coil.
For those interested, the mechanical cable (# 09415ODC at 5th Ave.) is "compatible" with the original handle. My cable was cut somewhere along the way and I was able to tap the handle off with a drift and if I drill a hole in it for a set screw it will fit correctly in place of the chrome one in this kit for those like me who like to keep as many original bits as possible. I bought my kit from National Parts Depot or LMC Truck; can't remember, but it's the same one shown here.
Can anyone confirm the solenoids used in these trucks have the 1" plunger?
I must have missed you posting it, but I'd be glad to add it to the tech articles. I'll PM you.
