Pic of 66 Ford 4500 block heater location and a ?

Ok, so how large is this opening?
I am assuming it is threaded.
Anyone know the size of the hex opening.

If/when I get it out, does the Zero Start
3100087 I bought fit in there?
the ZS is 2+ inches with a large o ring.

Tks

Yes, it's threaded. Not sure there are any block heaters that fit those openings... all I've ever seen have been for the later, press/tap in plugs. Most early 5000's I've seen, which also have those screw-in plugs have a tank-type heater.

Messicks shows one for the '65-6/68 4500 that appears to be threaded. Part number is D8NN8B152AB. Sparex has that in their catalog as S.67058 also, with the caveat "W/ threaded core plug. ... NOTE: Make sure Core Plug can be removed before ordering" That might be a bad sign..

Probably have to get creative to make a "female wrench" big enough to get a grip on the plug, maybe find a bolt with a head that is the right size and weld a nut onto it. Hopefully somebody who has done this before can chime in.

Hope this helps -

Greg,
Tks for the links to catalogs.

I was thinking I would find a bolt with a head that size? BIG and get 2 or 3 nuts to fit that bolt and weld them in place.

BUT, I am wary of removing this plug at this point. IF I damage it and it leaks or God forbid I crack the block the block heater ain't going to matter!

For now I am going to rig up a 2000 watt hair dryer to the air filter!

And was thinking I would buy one of those fuel heaters you slip over the filter?

I do not see a lot of room to install one of those inline lower radiator hose heaters either.

Suppose I will "gently" try to remove it and see if it budges at all.

Greg that"s exactly what I did for my NH TD95D. I had to grind the head to make it fit( female opening was metric) and a got a couple of nuts and snugged them down and welded them. Worked like a charm
 
(quoted from post at 01:34:24 12/23/11) I hadto use a 3/4"drive scoket, an extension, and a breaker bar with a cheater to loosen mine.

Wow. Is it pipe threads? Or is there some kind of o-ring or gasket involved?

The gasser I'm working on now is a '66 and has this style of freeze plug. If it was a diesel I'd be making that wrench out of a bolt..
 
Mot sure about the threads, I would assume they are pipe thread like and plug gets coated with permatex and screwed in.

As its raining again nothing doing today.

May use some of my kids clay and take a imprint to get a good size of the bolt head i need.

Best I call Messicks and speak with someone who knows for sure.

Tks everyone for the input.

I can't tell from the photo, but it's likely 1/4" or 3/8" pipe. Either way a Kats or Zero Start heater will work fine. I'd stick with a 1500 or 1000 watt model due to the small size of that opening on the bottom.

I've got a 1500 on my 1963 Ford 4000 industrial and also on all my other tractors (Deere, IH, Ferguson, etc.).

Kats and Zero Start recommend a 1000 watt tank heater for your tractor.

I just got done installing one yesterday on a British IH tractor that also has a small 1/4" drain plug opening I had to use. Just needed a few adapters. Hard to see in the photo.

I don't have any photos of the tank heater on my Ford, but this setup on my Deere is similar . .

A wee little bit of progress today.
Measured the size of the hex opening in the plug as bigger then my 1 1/16 open end, smaller then my 1 1/8 open end.
Got a 6" bolt and 2 nuts.
Head of bolt is a wee bit too big to fit in hex opening. Going to grind it 1st thing in the AM till it fits in opening.
Took the bolt, threaded both nuts all the way on it. Then took a steel punch and beat the last 2 threads on the bolt to oblivion! backed 1st nut out over that end till it would not move.
Then took punch and beat the crap out of last 2 threads showing on bolt before 1st nut. Backed second not out over that.
Socket fits over both the nuts.
The way I figure it I can try it and if freeze plug turns before these 2 jammed on nuts great.
Kinda has a margin of safety that I do not exert too much force on the freeze out plug.

With the 6" bolt I can probably leave the starter on during this test to see if the plug will even budge.

Tractor is outside so have to wait till morning.

LJD,
Sorry, I was trying to show the freeze plug in btw the fuel filter and the fuel pump with that pic.

Would love to see a pic of the setup on your Ford.

I, being a Rookie, did not even realize that there was a block drain valve right there to work with.

Where does the top hose go to on the Ford?

I do have this fear that messing with this thread plug could get ugly if its really stuck.

tks

Pete

Responding to my own comment. For some strange reason the hotel I"m staying at is blocking photobucket. .

wedge,

I uploaded the pic directly to the tractor shed here on YTmag.com.

The hotel wireless is probably blocking pics or files larger then a certain size.
