    Posted: 01 Jan. 2017 at 7:56pm
I have bought this temp gauge from Walcks as a replacement for mine which was no longer working:

http://walcks4wd.com/temp-gauge-late-cj2a-cj3a-cj3b.html

I have a few questions that others might be able to help me with.

  1. The bushing/nut for attaching into the side of the head is included on the probe. Does this replace the existing (original) brass bushing in my engine head? ie do I need to remove the original brass bushing and the one included with the Walcks gauge will fit right in it's place?
  2. As shown in the following photo from the Walcks website, the nut is loose on the probe. What stops water from leaking out if it is this loose?


Thank you.

Mike

That assemble should screw into the bushing that is on your existing head.

To seal it, clean your old sholder in the head, slide a o- ring that fits the probe, on until it hits the probe shoulder. Anti seize the threads and gently tighten. John

There is no way that the assembly fits the bushing currently in the head...

They look the same size by eye, but i can measure if needed.

Sadly the bushing currently installed in your head is not correct

W/O part number A-17160 should be what fits in that spot. It should have a hex face on the outside. Your bushing doesn't appear to have this and could have been for an electric gauge setup that might have been used on later models.

I think the bushing he has in there is broken off below the hex, and doesn't look to have the inner lip intact. I think the original was steel.

Thanks all.
 
I found a previous thread that seems to describe my problem. Here is it:
 
I am still not entirely clear how to correct my problem.

If I get this bushing out as in the thread above, will the machining in the head accept the nut that comes with the Walcks fitting? Will I find a shoulder machined into the head against which the probe  will sit and bear against?

Is this the same fitting that already comes included with the Walcks gauge I have (see photo above of what I have), or is this a new fitting that I need which the Walcks fitting on the probe will screw into?

 The bushing in your head needs to come out. It is just a plain pipe bushing used to make a smaller pipe fit into a larger hole. As someone said, it may have been in there to adapt an electric gauge sender, or to adapt a heater hose nipple.
  The "bushing" you need is correctly called an "adapter", and it has a step or shoulder in it that can't be seen well in the Walck's picture. The flange on your temp probe seats against the step and the fitting holds it tightly in place. There is no step or shoulder in the head, that is partly why the adapter is needed. The adapter sometimes comes with the new gauge, sometimes not.  No "O" ring or other seal is needed, as all the brass parts seal against each other, but I don't think an "O" ring would hurt anything, unless you tighten the fitting too much and smash the ring.  BW

Now crystal clear, thanks Bruce! Looks like I will be ordering yet another fitting from Walcks... Ouch and at least another 6 weeks until I can get this engine in and fired up. Unhappy I had thought I was a week or two away...

Sorry I didn't respond sooner. It does look like something brass got broken off. You'll need to remove that old bushing and install the adaptor as Bruce W. said. I find that old bulbs that have been in for years will lock themselves in and you almost always ruin it, by taking it back out. That's why the o-ring and antiseize. It doesn't take a large o-ring, just a small thickness one. I badly wanted to save a original that was going to twist off the small copper tube one time, so I very carefully removed the gauge bracket behind the dash straightened out the entire copper tube, and as I turned the adaptor and all out of the head, rotated the gauge in the hole. Shocked Then soaked and with sockets, tubing wrenches and a bench vise, got the old one apart. It went back in with the o-ring idea. 

That has to be quite frustrating, waiting for parts from another country. Paying all those duties, taxes etc. Good things come to those who wait! Wink John

I got my temp gauge from walks and ran into a similar issue. After I got the gauge I saw there was no way the threads on the bushing were going to fit. I had to order and pay shipping for one stupid adapter. Would have really liked it if they entombed it in their description of the gauge.
this is what you need, after you get that other thing out...

Armed with the correct thread pitches and diameters inside and out would you be able to source locally at perhaps a plumbing supply house?

The bushing in question has standard 1/2 NPT on the outside and 5/8 x 18 tpi on the inside***, but the difference is that on the inside there is a step or shoulder that mates with the bulb flange on the sender. It is not a standard pipe bushing. I'm sure one could be machined to work provided one had the proper taps and dies.

***edit to correct thread measurement for inside threads of special bushing.

It would be nice if Walck's would alert the buyer that they might also need Part Number A-17160 to complete the installation, but they don't.

Thanks all for suggestions and comments. Adrian in NZ has offered to send one from there in the hope that shipping is quicker than from the USA.
 
My second plan of attack is to contact some American doctors that I know that are currently home in the States for Christmas, and ask if they can bring one back with them in their hand luggage. Just waiting to hear back from Adrian in NZ on sourcing the part...

Good news! I made contact with the good doctors currently in the States and they will bring the bushing back for me when they return to SA on 13th Jan. So I should have the bushing by mid Jan. The order is in, so I guess it shouldn't take more than a few days to get to them in IL on flat rate domestic shipping?

Thanks to all for the offers of assistance...

Great, you'll have the fitting you need.  Now all you have to do is get the broken piece out.  I'm guessing that will be WAY too much fun...Ouch
