Mark Gregory Posted January 8, 2016 Share Posted January 8, 2016 (edited) I own a 1931 Reo Royale and the ignition wires run together across the head in Pipe - Conduit - Raceway to the spark plugs . Could someone please give me the proper name of this carrier for the wires . Edited January 9, 2016 by Mark Gregory (see edit history) Link to comment Share on other sites More sharing options...
trimacar Posted January 8, 2016 Share Posted January 8, 2016 Interesting question, easy to answer on surface but actually a mystery. Guess I've always heard them refered to as wiring tubes, but it does seem like there should be an "official" name.... Link to comment Share on other sites More sharing options...
46 woodie Posted January 8, 2016 Share Posted January 8, 2016 Mark, I can only tell you that in all the books I have, Ford called them "Conduits". As for other makes I don't know. Link to comment Share on other sites More sharing options...
frank29u Posted January 8, 2016 Share Posted January 8, 2016 For a 1929U Plymouth, the Parts Manual calls it a Spark Plug Tube. I don't have a picture of the entire part, but you can see the it is tubular. If you can find a parts book for your REO, use that term. Link to comment Share on other sites More sharing options...
1940TORPEDO Posted January 8, 2016 Share Posted January 8, 2016 Looks like my Pontiac book is calling it a manifold. Link to comment Share on other sites More sharing options...
benjamin j Posted January 8, 2016 Share Posted January 8, 2016 seems like they would have been called The cross fire inducer pipe if they were all ran through the same pipe. 1 Link to comment Share on other sites More sharing options...

keiser31 Posted January 8, 2016 Share Posted January 8, 2016 (edited) My 1931 Dodge Brothers parts book calls it an "ignition cable tube and bracket assembly". I have always called it a "spark plug wire distribution tube". As you can see, my wires are too long....

Guest AlCapone Posted January 8, 2016 Share Posted January 8, 2016 I won a 1931 Reo Royale and the ignition wires run together across the head in Pipe - Conduit - Raceway to the spark plugs . Could someone please give me the proper name of this carrier for the wires .Why do you ask, does yours need replacing ? Wayne Link to comment Share on other sites More sharing options...
Mark Gregory Posted January 9, 2016 Author Share Posted January 9, 2016 (edited) John that is exactly what I called it . The spark wire distribution tube . Wayne my original is rotted out but when I bought my car someone had supplied a reproduction part . It does not match the original exactly but will do the job . Frank29u the way your tube is flared is how my original looks . The replacement looks like a shower curtain rod pipe and not flared . I was wondering for other Royale owners looking for this part what it was called . Thanks Edited January 9, 2016 by Mark Gregory (see edit history) Link to comment Share on other sites More sharing options...

Taylormade Posted January 9, 2016 Share Posted January 9, 2016 Since we are on this subject, I have a tech question. I have the exact same tube that keiser31 has in post #11. I have my engine painted and the loom/conduit freshly powder coated black. As you can see in the photo, the tube attaches to the top of the cylinder head via two of the head studs. Now, you are supposed to tighten and loosen cylinder head stud nuts in a certain order and in measured increments. Can I safely just loosen those two nuts, or do I have to loosen all stud nuts to install the tube?How the heck did they do the install at the factory? As far as I know, the entire engine assembly (motor, trans, water pump, cylinder head) was painted in one shot. Since the cylinder head bolts would have also been painted at the same time, like mine are, I find it hard to believe the factory would then remove the nuts and install the tube. And if they left them off, wouldn't that mess up the head? Maybe they left all the nuts loose, left those two studs bare, installed the tube later on the assembly line and then torqued the nuts down. It would probably mess up the paint on the stud and nuts, but in mass production, and on an engine, would they really care?Anyone see why my wife claims I get a bit anal when working on my car?

I have had this conversation with myself a few times. You forgot to mention the horn. It also mount UNDER the cylinder head nuts and it is black. I can only think that the factory DID torque the head down and later loosened the four nuts to mount the horn bracket and spark plug wire distribution tube.

Taylormade Posted January 9, 2016 Share Posted January 9, 2016 Yes, I forgot about the horn. I guess I'll risk just loosening the needed nuts and hope for the best. Link to comment Share on other sites More sharing options...

Guest Posted January 9, 2016 Share Posted January 9, 2016 Mark, I can only tell you that in all the books I have, Ford called them "Conduits". As for other makes I don't know.VW and Porsche also call them the spark plug wire conduits. BTW those tubes cause more trouble than they are worth. Vibration of the engine causes wires to chafe. Ignition spark induction causes the cylinder which is being fired to cross or jump to the next spark plug wire and fire the wrong cylinder. As ignition systems starting in the mid 50's became more powerful the manufacturers stopped making them. Link to comment Share on other sites More sharing options...
