a tool I need

[CKain(MI)]

I am looking for a 7/8 SPARK PLUG WRENCH. not a socket, just a thin wall wrench. Not finding at local tool sources.
or even YT tools...

 

[SVcummins]

Like Tappet wrench ? Or do you need a box end

 

[Stephen Newell]

Could you grind the excess steel off the outside of a wrench to make it thin wall? I've ground many wrenches to fit a particular application.

 

[CKain(MI)]

Just a cheap tool, like this but 7/8. where do they sell them ?

 

[el6147]

I have looked for years for such a spark plug socket in 7/8, and I don't think they exist

 

[jCarroll]

Kobalt Shower Valve Socket Wrench
Item #2146949Model #58721

is close enough for a spark plug.

i have a few of them old original spark plug wrenches. one side was for the w series plugs and other side for the d series, in champion.

 

[CKain(MI)]

el6147, Yes thats what I find.(not) 7/8' deep socket will work, but for around $20..!
This is the plug size in my Ferguson. And I think in my Case DC.

 

[rustred]

like this.

That's one of those things, I want to say there's one in every old abandoned toolbox I have around here, but if I went looking for one, I probably wouldn't be able to find one. I know I have a 7/8 spark plug socket with a 3/8 drive.

NAPA has them, in their Carlyle line of tools. The part number is SSP3824. I bought one last week, $US 6.99 plus tax.

One note: The SSP3824 fits 7/8 inch hex automotive plugs but its ID isn't big enough to accept a 7/8 inch hex aircraft plug.

 

[John Garner]

Should have mentioned that the Carlyle SSP3824 is a 3/8 inch drive spark plug socket, 3 1/2 inch long with a 7/8 inch external hex so that it can be driven with a box or open-end wrench.

 

[JGayman]

Amazon sells those for $7.

Not what you're describing, but I have one of these in every tractor toolbox.

Made from scrap - a junk road find cut down socket, a short piece of 3/4 pipe and part of a tailgate strap from a '68 Ford truck. I don't leave nice wrenches in my tractor tool boxes.

 

[BarnyardEngineering]

That's the kind of tool that usually comes with the machine as a courtesy. You get something like that in a tool kit with every ATV and UTV. It's cheap so if you lose it no big deal, and most were lost.

I didn't think you could buy them separately.

I just changed the plugs on my GMC.
Each spark plug required a different extension on the 16 mm socket..I had a long handle ratchet with a flex head. That was very handy..

I'm not strong enough to use the socket you are talking about..

I find that Old Engine/Steam/Tractor Shows are a good place to look for old tools.

 

[gordy8n]

Look at oxygen sensor tools

 

[CKain(MI)]

JGayman, I have not found a 7/8 on Amazon ?

 

[CKain(MI)]

John, SSP3824 is listed as 3/4 ? My 3/4 socket not fit on the spark plug ?

 

[CKain(MI)]

John, I find a SSP 3828 socket, listed as 7/8. correct size! wow. Thanks.

 

[tech4]

Harbor Freight and others sell a bath and shower wrench set. It does not have a 7/8 but it does have a 29/32 that may or may not work.
Wrench Set

 

[Super H Mike]

Garage sale or thrift store wrench and grind it to suit? I have a whole drawer of similar modified wrenches labeled special .

 

[John Garner]

My mistake, and I should have realized that 24/32 does not equal 7/8 when typing the number. The correct part number is SSP3828.

Sorry 'bout that.

 

[oldsarge]

I've got an offset box-end came with my 2N, about the only thing will work unless you remove the hood,been there forever

 

[rustred]

i would have sent you one.
