VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1929-1932 Type B Electrolock Question

What is the proper sequence for the washers insulators and nuts at the terminal end of the electrolock? :confused: I believe I have all of the items required. Is the stud terminal supposed to turn? If so how can you get a good tight connection?

The electrolock is supposed to turn on the terminal stud.

Here is the order in which the parts are connected, starting from the inside of the electrolock and working out towards the distributor:

1. Spring and brush wire
2. Terminal stud with copper snap washer, metal washer and insulating washer
3. Brass stud retainer
4. Large paper washer
5. #10 lockwasher
6. Condenser wire eyelet (goes up through the terminal stud cup)
7. Small metal flat washer
8. Large Bakelite washer
9. Terminal stud cup
10. Round Bakelite insulating barrel
11. Large lockwasher
12. Rectangle paper insulator
13. Square paper insulator
14. Metal spacer
15. Point arm spring
16. 10-32 hex nut.

Originally, the terminal stud, condenser wire and all of the internal parts were connected to the distributor first and then the electrolock was snapped onto the tapered head of the terminal stud via the copper snap washer. However, since the copper snap washers are no longer available, the electrolock with the terminal stud and all of the parts has to be installed on the distributor "back asswards".

Well I am on the way over to where I store my car. I have to keep it safe and secure living in the cross hairs of almost every hurricane that comes into the Gulf. :( I will be back if I have any more questions. Thank JYD.

Sure! Glad to help out!

Actually the inside nut (# 16) was rectangular not hex. There was also a similar plate with larger un-tapped hole next to the insulator. It is # 14 on the doggie's list.

Number 16 was a rectangular nut that required a special electrolock tool to remove. Also, the breaker plate had to be dropped down when using this tool to remove the special rectangular nut. Installing this nut would only make matters worse for 30USA1, that's why I listed the 10-32 hex nut instead. It is easy to install, no special tools required and you don't have to drop the breaker plate either.

Ok, I checked everything I had. Starting with #4. Does this have a triangle opening? Next the #10 lock washer. Is this just a small washer that fits the stud terminal? The large bakelite washer I have fits the terminal stud cap and a nipple protudes out the end which would be the insulating barrel. Is this ok? I am missing the large lockwasher. What size is this washer? I like to keep it simple and easy! Thanks :cool2:

Yes, the number 4 paper washer has a triangle opening, and the lockwasher (number 5) is just a standard #10 lockwasher and it slides over the terminal stud.

The large Bakelite washer came two ways: A plain washer with a hole for the round insulating barrel to slide into, or a Bakelte washer with a protuding nipple, which would take the place of the insulating barrel.

On the number 11 large lockwasher, it had an I.D. large enough to go over the insulating barrel (or nipple) that connects the terminal cup assembly to the distributor. You can use a thin internal star washer with the correct I.D. instead, and it works better as well.

Great, I will connect all to the distributor today. Again, Thanks for all the info.

Cool! And, when you connect everything to the distributor, make sure that the internal parts are not grounded or your distributor will not work. Also, put some shrink tubing over the end of the condenser wire eyelet so that it is not touching the terminal cup where it goes up through the slot in the cup.

Well I hooked everything up in the order provided and it worked.

is there an illustration of how this all goes together? I'm not sure I have all the parts.
Where can I find an schematic of this?
Thanks, Roman

Order a 1929-32 Chevrolet parts book from the Filling Station in Lebanon, Oregon. There is an illustration of the electrolock parts in the book. :cool2:
