Tow Bar

[Dave_Butler]

I just purchased a 715. I need to fabricate feet for my tow bar system.

What is the width (loop to loop) of the front lifting shackles, and what is the pin diameter?

Thanks!

I kept searching until I found the answer. Here it is for everyone:

The pin is 3/4", unlike my M35A2.

Steel Soldiers had a photo of the foot, with measurements:

Is it forged steel or cast iron? I suspect cast iron would be too brittle?

I'm not sure. I'm welding up a clone now out of 1/4 plate steel. Won't look the same, but it will work the same.

If this works out as well as I hope, I'll post the drawings and the results.

I'll also develop a price to produce more.

Good on 'ya Dave. That makes sense. Those things go for crazy money. Only a few people (not me!) would even know it was not original. Glad that you have exact precise measurements. I look forward to following your progress.

Those measurements came from here. Jon did them for me when I was looking to make my own adaptors.

The lifting shackles for the M715 are indeed 3/4" pins. However, the stock adaptors are for the 1" tow bar feet just like the M35.

I took a set of M35 rear shackle mounts which have 7/8" pins. Bored them out to 1 inch and mounted them on top of my M715 bumper. Works great and a lot, lot less work than building stock like adaptors.

I have about 400 miles with my adaptors and about another 400 with the stock adaptors. I can't tell a difference between them when pulling it. I am going to use one or the other next week to drag the truck behind RED to the SS Texas Rally in College Station.
