I have been moving it from one place to another, each time I tidy the workshop, without any idea exactly what it is. I once thought it must be a part for the transfer case, but unless its for a PTO it can't be.

Any thoughts? Is it even for a CMP?

It looks like a front axle engagement lever for a single speed transfer case.

This is an interesting set of instructions for Allied Forces fighting in Normandy, titled....

Fighting in Normandy: from*Combat Lessons, No. 4A 1944, Rank and file in combat: What they're doing; How they do it. The purpose of*Combat Lessons*was to give officers and enlisted men the benefit of battle experiences. The article discusses the unique problems of fighting in the Normandy hedgerows.

The transfer case is now fully disassembled, showing some damage to a couple of the gears. I found that the thicker centre row gear had a bit if movement against the splined shaft. If I rotated it, there was some movement around its axis. Not really understanding HOW this wear could have occured. No visible damage to the shaft or the gear itself, but it cant be right, surely? If anyone has a replacement for sale, please let me know.

I have taken photos to post, just not had the chance to upload them yet.

Placed a HUGE order with the bearing shop in town. I thought the front end had a lot of bearings, but this transfer case takes the cake! Ordered 8 bearing cups, 6 bearings, and 3 seals.........so far. Im hoping to save several others.

I dont even want to think about how many gaskets i'm gonna need to make! There might be a whole day just in doing those. Painting the seperate parts should get done this Sunday, since there's bugger all possibility of rain. Very little rain has fallen since the floods last January. Guess i'll be buying another tanker load of water soon.

One last thing. Are the uni joints on CMPs the same as civilian used, or are they different?

Thankyou,

The U-joints are still a standard Spicer joint. I will post the number I used later.
The straps used over the joint caps are also an off the shelf product.

The U-joint crosses I used on my C15A are Spicer 5-178X and the U shaped bolts used to attach at the transfer case to transmission shaft were Quality Gear 3-94-18x.
Based on info in http://www2.dana.com/pdf/DSAG-0200.pdf it is confirmed these parts are often used together and that 3-94-18x is not only a number from Quality Gear but also a Dana/Spicer number. There's more than enough info in the linked document but the link between 5-178X and 3-94-18x (and 1350 series joints) is on page 26.

Mine were bought at the local heavy truck parts and service shop, my F-350 is about the lightest thing they work on.
One online source is at: http://www.northerndrivetrain.com/pr...PI-5-178X.html and http://www.northerndrivetrain.com/pr...-3-94-18X.html
These parts are also available fron Jegs online (for more $) and almost certainly other sources

...... you might want to bring one semi U joint if they need to measure the cups and crosses.

When I dropped the CMP front shaft on his table at the truck shop in Ottawa he looked at them and quoted the part number from memory.... and how many do you need,,,,,, 6 please,,,,, want them put in flat fee $10. each....

U joints are spicer at about $22.00 each

Some days you fget lucky.

Hi Bob

You hit one very important point in find the universal and U bolts When "I dropped the CMP front shaft on his table at the truck shop" the important words TRUCK SHOP.

First time I tried to find universal joints years ago stopped at the largest and one of the oldest parts stores in New Hampshire guy on the counter could not find them by size or application, no surprise it is a CMP. As I was about to walk out of the store I noticed that the far end of the counter had a sign over it saying HEAVY TRUCKS.

You can guess the rest, put the universal joint on the counter the guy asks how many you walks back and takes them off the shelf.

Cheers Phil

Hi Tony,

According to my very old invoice the small U-joints-are Hardy Spicer 5-178X. 3-5/8” across x 1-3/16” dia cups for my single speed xfer case but they are probably the same for the two speed case.

Note: They may require slight grinding of yokes at inside edge of cup holes to a small angle to allow crosses to fit through due to heavier construction of these crosses than originals. I noticed this had even been done to very old U-joints so it was a practice done for a long time. Some yokes even appeared "Factory" while others appeared in-field mods.

Will look for large U-joint Part No. but Large U-joints- 4-3/16” across x 1-3/16” dia cups were likewise best matched by placing on counter of someone who knows trucks as previously mentioned. I was told Bedford and many other trucks used the same u-joints.

Cheers,
