Builds: Brian creates a new sending unit

• CATEGORIES: Builds, Features

For all the customizations I’ve done, I have to say I was still surprised, delightfully so, to receive this update from Brian about his metamorphasis of a GM sending unit into a Willys tank.  Maybe it is just me, but it simply never occurred to me to try something like this.  Moreover, as I turned Brian’s work into a post, I learned a great deal about gas tank sending units.  Thanks Brian!

A quick note. After doing some research, I discovered one of the most common reasons for the older gas gauges to stop working correctly is a bad ground.  So, if you are having problems with your old gas gauge, check the ground at the gauge and/or sending unit.

Take it away Brian:

I have tackled a variety of planned tasks on my CJ-3B, but as with any project, I’ve run across some unexpected issues as well.  My gas tank sending unit is a perfect example.

*** DISCLAIMER:  Before I begin, please be advised that when doing modifications to a gas tank it would be prudent (understatement) to drain and dry the gas tank.  I hear gasoline is very explosive!!! ***

Prior to installing my gas tank, I decided to use an ohmmeter to test my sending unit to make sure it was in good condition.  Unfortunately, I connected my ohmmeter and discovered my unit was dead.  So, I thought this was a perfect chance to install a modern sending unit.

Btw, you can visit the 1945gpw website to get a nice overview about how to use an ohm meter to trouble shoot your old Willys sending units.

The stock unit on my CJ-3B is 40-0 ohm’s (which means the ohm meter would read 40 ohms when full and 0 ohms when empty).  As I am upgrading my gauges to auto meter gauges, I had to make sure I selected a gauge that would work.  There were four different gauges to choose from:  90-0, 30-0, 8-73, and 33-240 ohms.  Note that the last two gauges are backwards for our purposes — the gauges would have read full when empty, and empty when full (if they worked at all). Also with my new gauge, I felt I would run into a problem with the ground, so I decided to replace the sending unit and make it work right.

brian_gas_gauges

I had replaced a GM in-tank pump and sending unit on a friend’s truck and found a GM sending unit would fit though the tank opening of a Willys.  So, with that in mind, I started by disassembling the old Willys unit. First, I removed the sending unit and the sending unit base from the gas tank.  Next, I separated the sending unit from the base as I will be reusing this base (with some modifications) using my drill press.

brian_sendingunit1

With that apart, I turned my attention to the GM Assembly. I removed the sending unit off the GM assembly by cutting the tube up high. I went over to Mick C. and we machined a plug for the old unit (a machinist is a good friend to have!). This GM unit is 90-0 ohms, a perfect match to the Auto Meter 105-2641 gage. It is also internally grounded, note the two wires.

brian_sendingunit2
Here is the unit assembled. The new plug had a hole in the center so I could run the new gas line through it.  Also, the plug had a hole for the wires as well.   I drilled three holes around the radius of the sending unit base and welded the plug in place. You can see the welds in the image below.

brian_sendingunit4
Note the J-B Weld. There is about 1/8″-3/16″ between the top of the plug and top of the unit. I used J-B Weld to pot and seal the unit. J-B weld (http://www.jbweld.net/products/jbweld.php) claims to be resistant to gas (from the website:  “It’s strong as steel and impervious to water, gasoline, chemicals, and acids.”). DO NOT USE SILICONE!!!

[Editor’s note:  Mitch mentioned months ago that he had a problem using J-B Weld to seal an old gas tank.  Given the claims by J-B, maybe Mitch’s problem was more an adherence to the old tank rather than J-B itself?  Any thoughts Mitch?  This should be a good test of J-B and gasoline. ]

Now, I had to adjust the float to work correctly with the new unit.  I cut the arm at the first bend from the float then turned it 90 degrees. I also cut the float down an inch.

brian_sendingunit5

Note: there is a pattern to the bolt circle on the old unit. Index the sending unit on assembly so the float will clear the internal wall in the tank. The wall runs across side-to-side; the float will have to do the same.

brian_sendingunit6
Adjusting the float was easy.  I just held it to the top of the tank and bent the arm as needed.

One good thing about this modern sending unit is the rheostat can be replaced by removing two screws. You would have to get another one from a junk yard but can easily be rebuilt.
This works really well …  I love these types of projects.

1949_cj3a_stparisI’d like to see some more pics of this jeep.  It looks good in this pic and sounds like there have been some interesting mods.

1948 CJ-2A Beaverton, MI **SOLD**

• CATEGORIES: CJ-2A

1946_cj2a_beavertonUPDATE: **SOLD** Was $750

This looks in pretty poor shape.

Selling my 46 Flattie, just not enough time or money at the moment so it’s gotta go. Only bought this this spring so I haven’t accomplished much. This will also include a partially torn down Buick 225 Odd-Fire V-6. Motor had a bent push rod and has sat for some time. All parts except distributor come with it though, I may be able to get a distributor if that’s the selling point. What you see is what you get with this one, no seats, cooling system, or wiring. From the middle of the cowl back is all torch cut 1/8″ plate, not nice to look at but would take a beating off road. There is a trans, transfercase, and axles present but I have not checked them out and it is to be assumed that they need rebuilt. Best part is this thing has a clear title in my name.”

A Budget Friendly E-Brake

• CATEGORIES: Features, Parts

A reader named Robert noted my interest in an alternative emergency brake.  He purchased the one to the right and says it looks pretty good, though he still needs to install it.  While this isn’t exactly what I’m seeking, it is a great price at $4.95.

“Can be made to fit many applications. Originally designed as brake cables on Military trailers and Jeeps Unused/Unissued. Handle style and color may vary.”

Updated Site

• CATEGORIES: News

ewillys_homeAs you can see,  a couple days ago I updated the site design.  I had several reasons for doing this.  (1) the drop down menus were sucking, (2) the drop down menus wouldn’t allow me to do the top sliders like I tested (3)  the previous design was having some problems in Internet Explorer, and (4) the logo design wasn’t well designed for t-shirts, merchandise and an expansion beyond the web.

The next step in the process is to go back through all my posts and reorganize them into new sections, so changes will be ongoing …

Reader Question: The size of CJ-2A blocks

• CATEGORIES: CJ-2A, Features

A reader asked about the original size of CJ-2A hood blocks.  A quick search revealed this was a forum topic on the CJ-2A PagePlease visit the forum to learn more.  I tried to create a quick link to the picture in the forum, but the forum won’t let me, so here’s a copy of the drawing submitted and a great pic of a 1945 CJ-2A which shows the blocks really well.  There’s also a CAD drawing that you can find in the forum as well that should help with the blocks.

The photo was posted to the CJ-2A page forum by the forum moderator Sean and the drawing was done by Joe DeYoung.

You can still find parts for Capstan winches here, though they are out of the Capstan kits (which cost $2,650).  Brian also runs a ‘Capstan’s for sale’ page, but appears all sold out at the moment.   And here’s a little nautical history of the Capstan winch from wikipedia.  And here’s some info from the CJ-3B page on the Ramsey Capstan Winch, including some pics of the brochure.
