Spark Plug Wires

I need to replace some spark plug wires. I have some pre-made wires. Is there a way/trick to thread them through the spark plug wire tube?
Thanks! Rich

Take the plug wire boot off the distributor end start with #4 work your way to #1. If one jams up you can push pull #4 to help work the wire thru the tube...
 
I just did this, and used a piece of wire (with a little hook at the end, taped to the plug wire with electrical tape) to fish #1 and #2 through. Things were loose enough to push #3 and #4 past the wiring harness without help.

Why do folks find this so hard I have never had an issue start with #4 work your way down. I don't use copper core wires that in itself should make this operation harder but it doesn't. No fish wire needed I must be missing the hard part.

You must have a skinnier wiring harness running through the tube! Believe me, I tried multiple times without the fishwire…

Thanks for the information...I see you do not use copper core...what do you recommend?

Had some trouble finding the link for the wires. My mistake was clicking the obvious link in the first one, not the text above or below the link. Lots of good information, Thanks, Hobo.

Depends on your preference, some folks prefer copper core wires others prefer different materials, you might already guess by the way I typed it I like the copper core wires, but it's up to you what you use. But DO NOT use the automotive spark plug boots, mine has them and I hate them, there is no room for them tall boots under the fuel tank. Use ones for the tractor

You need to get the 90 degree angled boots. Not the straight ones.

Not sure if you have O'Rieley's Auto up your way?

The sell std ignition 7mm copper core wire sets; You cut to length, straight or angle boots. For some reason the 8-cyl sets cost less than the 6- and 4-?

I had to make a set for my Ferguson. And have enough wires/terminals for a 2nd complete set; save the ones that are too long.

Straight boots are fine on the Continental engines. Get the angled for the Ns.

A set was ~$20 USD

I have used 100's of sets of Belden wires they have been good to me. No way in ell I will use a cheap plug wire I have seen to many new cheap wires fail. Because I have installed so many sets I know what set I need to convert to a tractor application. None of my tractors have copper core wires I am happy if copper core makes you happy then use'em.

Or I could pull the same trick Allis used for the WC and go eh spark plug boots who needs those and leave em bare. (sarcastic comments wouldn't be myself without them) anyways Yeah I should probably get better boots, I skin my fingers on the now rough underside of the fuel tank a lot pulling the boots off, I says it once more DON'T USE AUTOMOTIVE STRAIGHT TYPE BOOTIES FOR YOUR SPARK PLUGS!!! 90 degree boots are better in almost every way except for keeping dust off the lower ceramic of the spark plug :) as for O'Rieley's Auto we do not, closest thing Canada has is Princess auto which from what I know is similar to harbour freight. or Napa, we do have Napa

yes as I said it's up to preference, also cheap replacement parts are a no. Nothing about these tractors is cheap, the enjoyment is expensive (fuel) and the parts are moderately expensive. But the reason we all come here is to keep these beauties running at their best regardless of cost, if one can afford it.

I've no need for suppression wires as I'm still running 6V + ground points ignition. Std Ign wires are still good quality.
 
It’s the same debate as 6 vs 12 volt, that seems to be a very heated debate around these places, but it all boils down to preference of owner/operator, I recommend copper spark plug wires for 12 volt conversion and hobo recommends Belden wires. As long as it’s all done properly it really shouldn’t matter

I think Hobo is using suppression wires since it is not only 12V but also a Petronix conversion.

Yes and No, I use this type of wire on most all applications. I don't drink the Kool-Aid If you do at the least get a wire with a silicon are EPDM rubber cover. Invest in the tools to properly crimp the ends on life will be good.
