Correct spark plug wires.

Postby J3 Driver » Thu Apr 06, 2017 8:12 pm

So as I slowly repair things on my son's 57 cub I am also trying to correct it back to oroginal equipment. I'm thinking about ordering a new set of wires and am wondering what type is the correct one for this year. Cloth wrapped or rubber coated.

I've looked in the Bundread series Farmall. lol. It it doesn't mention it.

Are you referencing the wiring harness? Brillman's has a good reputation on the forum for the wiring harness. It's important to use solid wire type plug wires.

If you are talking about spark plug wires, they were black wires, with solid core.
They had no covers at the spark plug ends, which makes them easier to put through the original spark plug wire holder, that was on one head bolt.
They make them with covers at the spark plug ends nowadays also, if you want that.
Here is a page from the Cub owner's manual showing them, and the holder, at the lower left. It is a dark pic some, turn up your computer light to see it. :) ... age-31.jpg

Keith, I am not sure if the originals were cloth coated. Here is a good set of non cloth ones sold by TM Tractor Parts, a sponsor of this site.

Actually, according to the item description on TM Tractor Parts, those are lacquer-covered cotton braid over PVC over solid copper core. So those are cloth... just... shiny cloth.

Another thing I have seen mentioned on here many times before is that the Cubs do not get along with graphite-cored wires like many cars use now. Use solid copper core only.

That set from TM Tractor is an excellent choice. Stay with copper core.
