Spark plug wire end crimping tool

Recommended Posts

I am working on a 1929 Hupmobile putting new spark plug wires on it and would like to know the proper way to crimp the ends on the wires.  It is the standard ends that get crimped on to cloth covered wire.  Is there a special tool?  What does it look like?  Has anyone done it with normal tools and how was the results?  

Thanks,

Dale

 Learn something new every day. I've been using pliers with acceptable results for over 25 years because I didn't know there was a special tool.

I used to crimp a lot of wires and I can tell you many of the tools sold for this purpose do not work worth a damn.

 

What do you mean by "standard ends"? I am guessing the type used on modern wires, where 2 tabs curve around and stab into the insulation like this:

In my experience, crimpers that combine spark plug crimping with something that looks like a hardware store crimper (even from Snap-On !) don't work worth sour owl manure.

 

I have one that works. It came from some wholesaler in Texas, circa 1992. MSD was selling the same one a few years later.

 

Look closely at this picture. This tool actually works. You might be able to find one used:

MSD currently sells a different tool that has thick jaws like a professional tool. It is expensive. It looks like a real tool that might actually work. I have not used it.

 

Back in the day there were also "Rajah" terminals. Note that they have a cylindrical area that you stuff the end of the wire in. They take a weird star crimper.

If that is what you need, one company still makes a crimper (Westwood T-200-10 695). It isn't cheap. I have no idea whether it works right. Otherwise you need to look for a decades-old used one.

I have a Joe Blogs (i.e. cheap, probably unbranded) version of the MSD crimper shown above. It is supposed to be for ordinary terminals and works well on them. I hadn't thought of using it for spark plug wires.

 

here is JEGS' version of the Dorman:https://www.jegs.com/i/JEGS/555/80575/10002/-1

Where do you find big enough wires to fit it that are not spark plug wires?

Well, the last job was a second brake light for my 1930 Dodge Brothers. I also used it to put on terminals when I overhauled the generator. Can't remember any further back...

The Jeges and Dormen looks just like the crimper I have that Beldon wire supplies with their wire kit and worked very good. Mike

I have Brillman www.brillman.com do my cable ends and they are 100 point every time.   I tried myself and have a nice pricey tool too, but have not been particularly pleased with results for something other than a driver quality car.

Yeah, its amazing how many of the "right" tools out there just make a mess. Brillman sure is a great source for wire and ends. I did not know they would crimp them up for you.

Spinney, He was saying the spark plug crimper is made for 7 and 8 mm wire, where the terminal crimps onto the 7 or 8 mm insulation, not just the 14 awg or so conductor.

 

When you crimped the terminals for the generator, the wire was not 7 or 8 mm diameter insulation, I hope!😉

No, but it worked! Maybe mine has an extra crimper for smaller wires. I'll have to have a look tomorrow.

Yes they will install any end that they sell and usually only adds a couple hours onto the delivery time.  if I order on a Monday first thing the parts are usually shipped by Wednesday if not earlier.

Good source. They show up at a local antique car flea market here in Fredericksburg. Great selection of "old" (brand new, just old type)  parts. 😉

As luck would have it a friend of mine came to my shop today bringing waste oil for my furnace.  He saw the Hupp and saw that I was working on the wires.  I told him I was looking for a crimping tool.  He told me he just bought one from Summit racing and said I could borrow it.  He hasn't used it yet.   It looks like a nice tool, About $50 he told me.  Worked great.
