1948 Champion Convertible top question.

[GasWorksGarage]

We have a 48 champion and the motor that lifts the top apparently isn't strong enough. It looks like I need to remove the rear seat and arm rest to get to it. Does anyone know how these come out?

thanks in advance.

Have you lubed all the pivot points and cables?

I haven't worked on any Studebaker convertibles, so I can't help IF the motor needs to come out, but usually the motor runs OK or is dead. Before removing the motor, I'd make sure the proper voltage is reaching the motor also.

The ball screws may be rusty. It's likely that the motor is not getting full voltage like TWchamp suggested. Make sure everything is lubricated. The motor is plenty strong. It just needs to have everything lubricated, nothing bent, and full voltage. Try it with the engine running at fast idle.

You should purchase the shop manual, the body parts catalog and the chassis parts catalog. They have lots of pictures and show how things connect to each other.

Thanks all. Everything is lubed and free. The screws run fine when unhooked. I will check voltage.

[RadioRoy]

The screws have to be set at exactly the same length as each other. If they are even one turn off of each other, they will cock and jam the mechanism. It's not like a hydraulic system that self levels the pistons.

Been there. I have to seriously question whether the dumb things ever worked. Took that crap out and raised and lowered the top manually. That worked just fine.

[RadioRoy]

Mine works fine and has since 1973 when I fixed it. As I have said before, you do not have to redesign these cars to make them work properly. Just bring them back to factory specification.

Raise and lower the top with the engine running at a fast idle.

To answer the other question, you must remove the rear seat cushion and back, plus remove the side panels and window handles to access the motor and the ball screws. The system is illustrated in the body parts catalog.

Thanks all. I started it and at fast idle it does the same thing about 1 to 2 turns then stops. Like the motor isn't strong enough.

[RadioRoy]

Maybe the motor needs brushes, has some crud in it, or maybe the wiring connections are corroded.

Mine works fine and has since 1973 when I fixed it.. As I have said at least a dozen times, you do not have to redesign these cars to make them work properly. Just bring them back to factory specification.

Do you know where I might find the body parts catalog?
Thanks

Studebaker International sell body and chassis books. So does the Studebaker National Museum. I was going to buy both the other day from the museum, but a good pair showed up on ebay for a cheap price, so I bought them. If I ever find the pair I bought from SI, then I'll have an extra pair to sell.

SI has a CD for reasonable price with the Parts book and Manuals for several usable other things. About half the price of one manual. Its in PDF.

I checked voltage at switch 6 volts going in 3.5 coming out and 3.5 at the motor.
What should it be?
Thanks in advance

[RadioRoy]

Sounds like the switch contacts are corroded. Should be 6 going in and 6 coming out. 3.5 is not enough. Actually, 6 is a misnomer it should be 6.3 to around 6.7 volts.

Sometimes the switch can be disassembled, contacts cleaned, silicone grease (not silicone seal) on the contacts and you are good to go. Sometimes the switch cannot be saved.

[GasWorksGarage]

It was actually 6.67 volts in and 3.54 out

anyone know where I can get a switch? PN: 288968 47 to 64 all used the same switch.

[RadioRoy]

Sounds like the trouble is inside the switch. Losing half the voltage inside the switch is WAY too much. You might clean the cable ends also.

I suggest calling SI during business hours. They have many things that are not in their catalog.

Is it possible to disassemble the switch to clean the contacts ? Check the terminals and conductors on the line and load wires at the switch.
Be aware that a NOS switch [NOS means OLD] can have corroded contacts just from sitting on a shelf for 66 years.

What happened with this? Any progress?
