carb drain plug

I posted w while back about getting a carb bowl drain plug out. After using the methods recommended buy you guys, I got it to turn! Or not. I turned the the stub head
right off the rest of the plug. So now what. Do I just chuck that bowl and look for another one? Or is there a magic way to get the plug out?
 
Hard to say with out being able to see it. You maybe able ot open up the carb and drill it out from the inside or take it apart and heat it up and then be able to free it up. Or you might be able ot get it out with a left hand drill bit.
 
Here's what it looks like from the outside.

They can be a bear sometimes. I heat them. Carefully.
Then turn them out. Since it is already broken off I would
smooth the broken top end enough to center a drill, drill it
most of the way through, heat it and use an extractor.
If you decide to replace it send it to me so I can give it whirl!
 
Just thought I should say, I hope I don't sound like I'm complaining about the idea's you folks gave me. They are certainly all great idea's, Just didn't work for me. Sorry if that came across the wrong way!
 
Since you have open access to it from the inside I would heat it up a good bit the bowl part my the plug then take a normal drill from the inside and try to drill it out. Be sure to use a drill bit that is less then half the size of the plug. That way you may get lucky and spin it out and if not then you can maybe use an easy out. I know if you had the easy outs I have you would probably get it out but the set I have are not cheap and cost me $75 over 15 years ago
 
"Feeling kinda clueless right now. What is an extractor?"

There are different types of extractors, some round and tapered
like the common easy out type. The ones I use if/when I have
to are more like a left handed tap. They are square.

I have better luck with those. I "think" because they don't
expand the metal out as far as the more tapered ones do.

They also tend to strip out the hole a little easier, which is
fine by me because then they don't break off in the hole.

Most any of them are hard and brittle so if one breaks off it
is extremely difficult to drill it out and try another method.
 
I bought that same set last summer and have had only occasion to use it.... worked fine and others have given GLOWING reports of it as well.... you mileage may vary... but I was impressed so far.
 
found a almost identical set at sears for a buck more. And sears is about 15 mins closer then harbor freight. Probably go with Craftsman.
 
can anyone tell me the original size of this drain plug? i might need to open mine, and i can't tell what exactly it started out life as. no socket i have wants to fit :(
 
7/16 is the original size I believe. I have never worked on a single N with out that carb plug all out of shape and ripped up bu this is the worst I've ever come across.
 
It's a 1/8 inch pipe plug. It had a 7/16 inch hex head.
I've seen metric square heads, 1/2 hex, one 11/16 (must have
been home made) and the ones the local store sells here are
1/2 inch hex on 4 sides and 12 MM on the other two. :shock:

You might try something like [b:7aa124b599]these.[/b:7aa124b599]
Still could twist it off, just like with a pipe wrench.
But these are way "cooler". LOL

thanks, tracto-man, that's what i thought it had to be.

my 7/16" wouldn't go on, and 12 mm 12 point just spun - but the 12 mm 6 point broke it loose :)

now i need to replace that ugly thing. what size is the plug, if u know, and why do they all end up mangled?
 
and, of course, i manage to miss royse's post :lol:

ty, a 1/8 plug is on my list now. cool tools are always good tho, even tho a plain old socket ended up working here :)

ok, these guys sound like troublemakers to me.

any idea why these plugs all end up the topic of a thread like this one?
 
"why do they all end up mangled?"

People too lazy to go get the right tool.
"I have pliers/vice-grips/etc at hand, that should work."

If you have your oil changed at a quick lube place, you might
want to check that drain plug too before its too late.
Let me see if I can dig that picture up..........
 
When I have to replace one I use a radiator type that way I have an easy open and close set up and my 1935 JD-B has had one of those on it for at least 4 decades

This is the oil drain plug out of a 3400 in a Chevy Impala.
Thanks to people too lazy to get the correct tool for the job.
Quick lube "mechanics" using water pump pliers.

"Drill it out from the inside"!!!????
Great advice from someone who has clearly never seen one from the inside!
Some "vast experience", huh?
He needs to insert his "Tractor Guru" card into the shredder!!!
Just a LOT of hot air.
 
Never been to one of those quick lube places and hope never have to..He ard other horror
stories though--plugs left loosw, leaking etc..
 
Thanks for the advice Old! I can get 2 Snap on easy outs for $54, or a little set at sears for $10 bucks I'm hoping will do the job.
 
For what it's worth you could put a nut over that and weld it on. Then while its still hot turn it over and melt some candle wax to the inside to lubricate the threads and turn it out..
 
Sure wish I had a welder. I actually did think about that. May have a friend try that if the screw extractors won't do it

e sure to post a picture of that plug drilled from the inside ( Old's advice), because many want to see how that is done. Thank you.

What Jammison, says here, is gospel!!!!
I've never heard of ANYONE, being able to...."open up the carb, and drill out the drain plug from the inside"!!!!!
CAN"T be done, with out tearing the bottom of the carb bowl up!!!!!

'OLD' MUST BE OFF HIS MEDS!!!!!

Tracto-man.......listen to what Royse says.!!!! He knows what has to be done!!!!! He has done enough of those drain plugs, to know what works, and what don't!!!!


"From the INSIDE of the carb bowl?????????"
Smooth move, EXLAX!!!!!

Ah depends on the carb form what his picture show it look like the drain plug is to the side so open to being drilled but his picture is not all that good. Some carb it is easy to drill from the inside some yes they can not be with out destroying the carb.

Rich......I'm not sure what you are looking at in his pic, BUT it dang sure is NOT the drain plug for the bowl.
If you are talking about the 'Weep' hole,,,,,that is Not even close to where the drain plug is!!!

Drain plug cannot be seen from the inside of the choke chamber!

thanks, old - i like the sound of this.
 
In his first picture yes you can see it is one that can not be drilled out from inside but in the second one which is the one I looked at it look to have a drain plug on the one side. Again you have to remember I do carb be it for a Ford 8N or a Farmall or an AC so can not always take the time to look at each and every one so ya some times you can drill form either side and others you can not.
Now the crack about the meds that is down right hurtful and on called for I do not jump you on anything. I had to go out today and find a hyd shop so when I got back home I checked a few tractor I have and one many of them as in most of the tractor I have ALL the drain plugs can be drilled out form either side. 841 ford AC WD45 D-17 C Oliver 77 and S88 etc so again you have to think abut the fact I work on many not just the N series so at times I give generic answer that do not always fit all application. all those tractor have the M/S carb by the way

at times I give generic answer that do not always fit all application." You got that part right, far too often! Congrats!
 
"They also tend to strip out the hole a little easier, which is
fine by me because then they don't break off in the hole."

After the fact, I realized this didn't sound right.
When I said "strip out the hole" I meant the hole I drilled.
NOT the hole the screw/bolt/plug is installed in.

If it strips out of the hole I drilled I can drill a larger hole
and use the next larger extractor. No harm, no fowl.

Unless you drill a hole big enough to reach the threads.
 
The plug is in there hardy then any of my drills. Battery drill couldn't do it. Corded drill couldn't do it. Don't have any thing else to try.

Maybe you would be better off just leaving it plugged for now ?
 
At least it is still usable as is if you need to get up and running.
Once you drill a hole through it all bets are off.

If you replace it and want to get rid of it, I love a good challenge.
I'd pay the shipping if you're willing to send it to me.

i was just looking at the equivalent plug on the WD. strangely, that plug looks like... a plug. the hex head is fine.

i guess allis owners have more sense than ford owners, huh? ;)
