Lock out switches were common on the early Lincoln, Ford, and Mercury R10 overdrive transmissions but they were deleted in 1951. |

Re: Borg Warner OD Question
The original Borg Warner installations were controlled by a relay and a governor. The governor did not allow the overdrive to activate until the car reached a speed of about 35 mph. This prevented any damage from backing up with the overdrive engaged. It also prevented the solenoid from being powered when the car was parked. They also had an over ride switch associated with the gas pedal that would disengage the overdrive temporarily if you wanted to accelerate.
Most Model A modifications did not include any of these features and often the overdrive was damaged when attempting to back up with it engaged. There were often incidents of a dead battery when a Model A was parked and someone did not turn the solenoid activation switch off. I had three Borg Warner overdrives installed in Model A's back in the day and I took advantage of all these features when I installed them.

Re: Borg Warner OD Question
Thanks Tom. My plan is to use a relay and governor setup. I really like the idea of having everything in place but probably won't utilize the kickdown switch.

Re: Borg Warner OD Question
I decided to tackle installing the B-W overdrive this weekend. i really don't know why I was dreading this job because it has been pretty easy so far. Will probably finish up this morning and then will tackle the wiring. Still not sure which diagram to use for my 6v system.

Re: Borg Warner OD Question
Got everything working except for the speedometer. I determined that the OD is from a 53 or 54 Ford truck, so I bought a speedometer cable and gear for that. It fits and the gears mesh and has a 5/8"-18 Female nut with square drive on the other end of the cable. Anyone know how I can connect that to the 7/8"-18 Female nut with tang drive on the Model A cable? Looked at catalogs and websites and nothing is exactly what I need. I thought about splicing the 2 cable housings together and making a replacement inner cable from a parts house replacement. Any suggestions?

Re: Borg Warner OD Question
Texas Industrial electric has speedometer fittings etc. They can even make up a custom cable.

I see this guy on the HAMB from time to time. Haven't had any dealings with him myself, but he seems to be solving any issue that comes up.

That lever DOES NOT engage nor disengage the overdrive! Engagement is done by the solenoid. The lever is a lockout lever. In the forward position (photo #1) it locks the trans in direct drive (the solenoid is blocked from engaging overdrive). In the rear position (photo #2) it allows the solenoid to engage overdrive when energized. |

Thanks, I figured that out when I tried to drive it a while back. No reverse. |
