Overdrive Lockout Cable source
#11
Just can't stay away
Just can't stay away

I recently replaced the R-11 OD lockout cable in my 1950 Standard Eight. My old cable had become rusted and just wore out.

After much searching, the only source I could find was Seattle Packard, owned by Dave Moe. The price was a bit staggering at $395 plus a $150 core charge, but I went ahead with it anyway and it worked well. At least I had a core to swap out.. without that the price would have been $545.

Please be aware there is also an overdrive lockout switch that is associated with the cable assembly. That switch keeps the electrical parts of the overdrive from attempting to engage when the OD is physically locked out when you pull on the cable. If you forego installing the switch you risk damage to the overdrive when it is locked out. Seattle Packard sells that switch for $95.

Lastly, Seattle Packard's lockout cable assembly does not come with the plastic knob that screws onto the driver's end of the cable. Kanter sells that knob for $40.

All the best,

Mark

That is a bit pricey. My R11 is on the garage floor and my Packard runs very good as it is. I do but plan to continue gathering parts. I have one question for the experts. In the electrical drawing for the R9 and R11 there are marked differences. Since mine is an R11 I hope I do not require a reverse lock out switch? Hopefully when the R11 was engineered it solved this issue.

It was. The R11 is a completely different mechanical design. That reverse locking up problem with the R9 that caused the retrofit of the safety switch and of course, the advancing age part of the R9 was one of the main reasons for the switch to R11s. There was even a kit made available to field switch R9's out if the owner wanted to pay for it.

One other thing is what year R11 is the one you have. The 51-4 ODs (maybe those are R12s - although the BW manual on site shows them as R11) had the lockout switch on the end or side of the OD case rather than on the lockout cable knob end. If there is a rectangular box with terminals or a place for one on the side or end of OD --same side the lockout lever is on, it is one of the later ones. If that is what you have, you would have the option to use that switch & then it might be possible to get an aftermarket cable assy for a lot less & paint it properly. Depending on the type you found, thread the shaft and put the proper knob from Kanter or Yesterday's Radio on with no one but you the wiser.

I guess I have a late model R11 that I installed in my 38 coupe. There is no electrical reverse lock out switch - there is an internal plunger that is activated by an ear on the reverse fork.

The reverse safety lock out switch was a retrofit added to R9 cars in 47 and was available or could be installed on earlier as well. Even with the reverse lockout plunger which they all had, if a bad switch or electrical short kept the solenoid engaged on the R9, because of the mechanical construction, going into reverse and applying power would lock and could damage the OD. The safety switch forcibly cut the power to the entire unit via the gearshift linkage so the solenoid had to drop out. R11 was a different mechanical design so no longer had the problem. The other regular lockout switch just keeps the OD from engaging in normal operation. On the R9 it was in the ground circuit to relay, R11 is in the power side.

These are the marking on the case of the overdrive unit.

R11-1B
WG DIV
A189

There is no rectangular box with terminals on the side or end of OD. I guess I have an earlier model. Thanks for the information the more I learn the better this project will go.

OK, that explains the "mystery" reverse switch on my '41 - 180 (R9), that doesn't have backup lamps. Can you tell me where the retrofit wiring cut into the OD control circuit?

Details of the problem with R9s and change are in SC 21 #15http://www.packardinfo.com/xoops/html/downloads/SC/SC-VOL21NO15.pdf but here is the schematic showing the reverse switch in the power feed circuit between battery and relay.
Note: They mention Clippers but the switch was applicable to all R9s.
