Guest 1930 Posted August 28, 2012 Share Posted August 28, 2012 Hello Stakeside, if you post a good picture of what you have I may be able to help. I dont know what column or box you have in your truck nor if the levers or linkages are the same as autos. A picture is worth so much. Link to comment Share on other sites More sharing options...
stakeside Posted August 28, 2012 Author Share Posted August 28, 2012 Hello Stakeside, if you post a good picture of what you have I may be able to help. I dont know what column or box you have in your truck nor if the levers or linkages are the same as autos. A picture is worth so much.The two examples are pictures of the Victory engines but the linkage appear similiar to mine. I can't see the linkage connectionsbut the spark linkage appears to be on the drivers side and the throttle appears on the pass side. I can't see which lever controls the linkage.The closeup views was my first attempt to connect the linkage, but dosen't agree with the example pictures.

Guest 1930 Posted August 29, 2012 Share Posted August 29, 2012 Different gear-box ( as I figured ) than auto so not the same linkages. I would be more than happy though to show you what I have in my AUTO if you like? Link to comment Share on other sites More sharing options...

If there are both spark and throtte linkages I would like to see the linkage setup. Link to comment Share on other sites More sharing options...
Guest 1930 Posted August 29, 2012 Share Posted August 29, 2012 I am guessing you mean by spark linkage you are referring to dist. advance? This is actuated by cable on my car Link to comment Share on other sites More sharing options...
farrellg Posted January 27, 2014 Share Posted January 27, 2014 I started taking my 1931 U124 3/4 Ton truck column apart tonight. Distributor advance seems same as above picture on the car. Cable runs throughout Clum switch at the bottom of column. I have the light switch tube and advance rod out of the column. But have not taken all apart yet. It appears to me that the cable runs all the way up the column. But will confirm when I disassemble. I will need to find a replacement. The cable diameter seem smaller then what I have used for chokes and carbs. Will need to do some searching. Link to comment Share on other sites More sharing options...

All the wiring on my 29 DB truck was steel cable encased and I found it rusted into the tube. I was unable to remove it. I found that a straight section of steel brake line could be used. You will have to braise the four pronged horn button base to the tube. The tube is slightly smaller so the steel wrapped cable could not be used here.What Clum switch do you have? Got a picture? I had to rebuild mine. Link to comment Share on other sites More sharing options...
farrellg Posted January 27, 2014 Share Posted January 27, 2014 Here is a photo of the Clum switch. I will take some better photos. I think my cable is free in the tube. Only time will tell. I know how fragile the horn button an assembly is, so going real slow. I would be interested in what you did to rebuild the switch. This is clearly a collection point for grease and oil. I have to get it cleaned up and see what I have. Link to comment Share on other sites More sharing options...
stakeside Posted January 27, 2014 Author Share Posted January 27, 2014 Good news if wire is free to horn button. Rebuilding the switch was a bit of a trick. Hopefully you can clean yours up. What is the switch model? A number should be stamped on the switch.If you carefully bend those steel tabs the Bakelite cover plate will be free. Take plenty of pictures for your records.

30DodgePanel Posted January 27, 2014 Share Posted January 27, 2014 Great topic ! I'm not ready at this point in my work but this topic has been on my mind since I bought the truck and would love to find any clues that may help in the future when I am ready. Please share plenty of photos if you would. Link to comment Share on other sites More sharing options...
farrellg Posted January 31, 2014 Share Posted January 31, 2014 Took the horn apart today. My horn wire is free in the tube. Anyone have a source for this armored wire. Working on the switch next. Also looking for ideas on bringing a shine back to the Bakelite horn button and surround? Have folks painted them etc? Link to comment Share on other sites More sharing options...
Ron Lawson Posted February 1, 2014 Share Posted February 1, 2014 Hi George My Aussie Bodied 2249 Senior has Bakelite inserts in the door handles as well as the horn button and its surround I used a product called Purple which is a metal polish Started with Purple on some 1200 wet and dry to remove the excess oxidation and the polished them with Purple on a cloth The came up very good Hope this helps Ron Link to comment Share on other sites More sharing options...
stakeside Posted February 1, 2014 Author Share Posted February 1, 2014 Try http://www.restorationstuff.com . They have an online catalog showing the shielded cable. Were you able to find a clum number on the steel casing? If so what is it? Here is my switch. There is another thread on this item. I will check what my model number is.

farrellg Posted February 2, 2014 Share Posted February 2, 2014 Stakeside, my Clum switch is 8821. 5 terminals but numbered 1 - 6. I believe for the horn button. Link to comment Share on other sites More sharing options...
stakeside Posted February 2, 2014 Author Share Posted February 2, 2014 Stakeside, my Clum switch is 8821. 5 terminals but numbered 1 - 6. I believe for the horn button.There are many different Clum switches. Most I have seen were square and not round. My switch terminals are for dash light, tail light and headlights. The passenger car Clum switch has an additional terminal. The horn wire (D2) runs thru the center tube not from a terminal. See attached wire diagram.Do you have a wire diagram? Will you be building your wire harness? Link to comment Share on other sites More sharing options...
farrellg Posted February 3, 2014 Share Posted February 3, 2014 This one is round. I have the wire diagram from the instruction guide. I am going to do it myself. I have done several before on tractors. I do have what is left of the original harness. One thing I have seen to make it easier to do, is lay It out on a wall. You can actually lay the original right next the new one you are building. Link to comment Share on other sites More sharing options...
stakeside Posted October 24, 2014 Author Share Posted October 24, 2014 This is my Clum switch model number 889. Only has 4 terminals. Is there a model 8891? Link to comment Share on other sites More sharing options...
keiser31 Posted October 24, 2014 Share Posted October 24, 2014 I see an 8821 number, but no reference to 8891. That list I have may not be complete. Link to comment Share on other sites More sharing options...
