Can some one give me the size of the exhaust nut. I Am out of town so can't measure one of mine. that is the nut that holds the exhaust pipe against the exhaust manifold.

Jim, thanks, I am close to you in Wenatchee. I have a chance to buy a wrench with a 1 7/8 open end and a long handle. I can modify it when I get home easy enough.

Steve, thanks, I can still modify this wrench if I buy it. I have a couple of original manifold wrenches but this one would give me more torque to remove the nut if the manifold is still in the car. I sometime have heated them but I think that is a real fire hazard. One time many, many years ago I found a manifold out in a field with some other T stuff. It was super straight. I took it home and put it in a vise and when I went to force the nut off I tore the end clear off the manifold. I should have heated it fist before I tried to turn it.

Ok, you made me look. My wrench is 2" an it fits snug on three nuts I have here. Based on a forum search it seems that most report 2 1/16", that and a 2 1/8" would likely work too.

Jim

The five I measured seemed to vary between 2 1/16" and 2 1/8", depending on how well-used they are.

There are two makes of pack nuts being made. Bergstadt and Snyder. Snyders are the best as far as the fit goes, and is somewhat loose on the wrench. Snyders measures 2 inches exactly. They are chamfered on the bottom unlike the original. Bergstadts are all over the place, and are not consistent, but look beautiful, just like the originals. What I have to do with them is sand them down with a belt sander or a file to fit the wrench. I just measured an original Ford nut and it measures 2.020-2.025". Bob says very few people own a pack nut wrench, which I find hard to believe, and maybe that is why Texas T parts makes that clamp thing to go over the pack nut.

I like to back my manifold nuts with a MUFFLER CLAMP. Seems to work well for me. I have been using Bergstadt's manifold nuts for many years and my original wrenches always fit.

In this camp there are one 15 2-18's and a 20" adjustable.I have only used them on pack nut's twice in 20 years so i think i'll skip the special wrench.Bud.

The Ford wrench measures 2.25. I have two here and they are both the same.

2.025". Sorry

Several years ago, I aquired what turned out to be a Model A rear axle gland nut wrench. It is a genuine Ford "Z" wrench which just happens to fit a Model T exhaust nut perfectly.

The only problem with it is that it is so massive, you can easily put too much torque on it resulting in the dreaded two-piece exhaust manifold.

There are also adjustable wrenches available from most hardware stores. They are available in 18 inch lengths and can be used for a lot more things besides the exhaust nut.
Just a thought as I know that some of you dislike the adjustable type but they do work good on the exhaust nut.
I have a special Ford wrench for this nut, but I have more than one car and some of the nuts it fits and some it is to small, the adjustable fits them all.

It could be several years ago, that Bob was selling Snyders pack nuts. Maybe he still does, I don't know. The ones I'm referring to are the latest ones he is currently selling. I just bought 10 of them from him, and only one fit the wrench all the way around. Bob is aware of this, but says few people own pack nut wrenches. I personally carry one in each one of my cars, because you never know when you are going to need one.

When a nut does come loose it sounds like all hell broke loose.

Mine nut split on the Kanab tour and yes Dave; it did sound like that. Found some muffler tape and hose clamps and finished the tour. Not pretty, but it kept the noise down. Like some of the other posters, I have a nut wrench and several nuts---with dimensions all over the place. I too usually use an old large oil field adjustable wrench.

I've never had any trouble using an 18" pipe wrench on mine, and even a large pair of Channel Locks.

The reason for the offset on a packnut wrench is so you can turn it easier. If the handle were straight it would be harder to aim it. They are making a reproduction now, so there is no excuse for anyone not having one, plus originals show up on ebay often. The prices are getting up around $30 now for an original.
