Looking for the proper freeze plug

Fiveflat · Dec 7, 2020

I have a ford 1700 with a freeze plug the previous owner decided to silicon around.
It finally popped and now I need one...
Looking at the website below, I need freeze plug #4
However, when you look at the list on the right, it's not listed.

I measured the plug after I got it out and it comes to 2.262" or 55.455mm

https://www.mycnhistore.com/us/en/n...-1700/cn/735BB1CD-B8BF-E111-9FCE-005056875BD6

Does anyone know exactly what size I need here? I use this tractor daily and I need to get it up and running again as soon as possible.

Thanks in advance!

I can't help you with the actual size needed, however I can say that soft plugs are categorized by the bore diameter, and not
the diameter of the plug itself. For example, I just bought some soft plugs for a SB Chevy. The plugs say right on them, "1-
5/8", and the bores in the block measure exactly 1.625". However, the plugs themselves measure 1.640" OD.

If you measure the bore diameter accurately to within a few thousandths of an inch, most good auto parts stores should be able
to hook you up.

That's a good point and it makes sense too because that would mean I need a 2-1/4" freeze plug

Thanks! I'll double check the bore tomorrow.

The freeze plug that you're looking for is listed on Messick's website. Here's a link to the parts list for your tractor:

New Holland: New Holland 1700 - 2 CYL COMPACT TRACTOR(01/79 - 12/82) Parts Diagrams

They show number 4 on the list as part number SBA064100055 then they show 4.1 on the list which is the same part with a part number of 47748689 and it says that it replaces #SBA064100055. Price is listed at $21.20. I hope this info helps!

$21 for a freeze plug. That's sounds about right for NH. To top it off, it'll say "made in China" on the box and pop out in operation. See below.
Check this out.

Measure carefully. I wouldn't bet on the fact that a Japanese engine uses standard size plugs.

(quoted from post at 06:37:30 12/08/20) Measure carefully. I wouldn't bet on the fact that a Japanese engine uses standard size plugs.

That is another great point! Surprised I didn't think of that myself.
The more I look at it it's not a typical freeze plug either. It's a flat plate. It is not an open circle behind this plug.
I'll gladly pay that $21 to have the proper part

Thank you everyone!

Thank you for that Amazon link!

Now to get to that plug easily I should probably remove the fuel injector. Is that an easy task to put back on? Will I mess up timing or anything like that? I've never fooled with an injector before but as I recall if it gets rotated or something it can foul up timing?

That Amazon link shows the plug as being 45mm, not 55mm. I don't think I'd run out and buy that.

You don't need to remove a fuel injector to replace a soft plug in the block. An injection line, maybe, but not an injector. You won't hurt or change anything by removing a line. Just keep everything clean.
