Torsion Level Operational, or not?

I have been through every component, except taking the actual compensator gear box apart, and my 56 Executive's TL system is just not working correctly. The rear end seems to be stuck, no longer raising and lowering, either automatically or with the manual switch. All cross links and the center 'yoke' are in their correct positions, according to the pictures in the service manuals.
I removed the compensator control box and drilled out the brass rivets holding the cover on. Upon inspection, it was clean as a whistle. One of the metal contacts was slightly bent away from vertical, so I bent it back to the vertical position. This was a contact for the moving lever, that is operated by the tiny rod link attached to the driver's side torsion level rod. There were several bad or questionable wire connections that I corrected, one by one. I used 'crimp' connectors, because I absolutely SUCK at soldering! I am thinking that the issue might be mechanical, at this point. What are your thoughts?

Thanks for the quick reply, as always. The motor does run and the connecting rods don't seem to move. I'll check further. After all the TL drama that I have had, I would still rather have it rather than a conventional spring suspension.

Had the same problem with my 56 Patrician.The previous owner used the override switch to operate the load leveler.When I got the car, the motor worked but nothing happened.It appears that the override also overrides the limiter switch.In my case, the gear box basically destroyed itself.Replaced the gear box and motor, fixed all the other issues that he never bothered to and now it works as it should.

In addition to what has already been said,
Can you observe the system when you manually operate it? Do you see the bars moving at all? My 55 Patrician had an issue once where the outside of the case would spin, no bar movement. I tightened up the case screws and the problem was fixed. https://www.packardinfo.com/xoops/html/downloads/servicemanual5556/Sect16_Suspension_Steering.pdf

Excellent point on the slipping center ring. Not very common but just a friction hold so with the units other issues it could have loosened. It is the mechanical transfer point between the two sets of planetaries so under a lot of load.

It appears that the override also overrides the limiter switch. If it is properly installed, it does not over ride the limits. The proper install is to parallel the control box relay outputs connecting the manual switch at the control box terminals which is before the limit switches. A connection there and limits stay in the circuit. The factory manual switch also has a second set of contacts which disconnects the control box as soon as manual switch is moved so the two do not "fight" when manual is chosen and car moves enough out of level the control box would want to bring it back. An aftermarket switch should be wired the same way also before the limits but won't have the disconnect function. On those installs the operator must remember to turn off the TL toggle switch under the dash before using the manual override or fuses will blow.

I have found several wire breaks, all of them in the 'yellow' wires that goes thus: 'manual switch' to 'control-box terminal' to 'down limit switch'. As I mentioned, I SUCK at soldering, and I used Crimp connectors, which I need to check again. One other problem is that the TL wiring diagram states that the manual switch is "grounded through switch case". That may be an issue as well. My metal dash was re-painted way back when I had my interior done. The necessary ground may be hampered by the new paint (since I installed the manual switch after the interior was done).
All of this must be corrected b4 I can thoroughly check the actual mechanical movements of the TL system. Then I'll find out about the motor, pin and rod movement. Thanks for all the hot tips, every one of them is a blessing ![]()

Now that the beautiful sun has finally appeared
![]() I must examine all switches and all wiring and repair or replace any questionable wires/connections or components. It's gonna take me some time to get through this one ![]()
