Pintle Hitch

Post by Rdinatal »

Can someone please take a picture of the pintle hitch and how it's bolted to the frame crossmember? I believe mine is mounted incorrectly or missing a piece.

Also, when the tailgate is down does it hit the hitch?

Thanks in advance.

The pintle doesn't get close to the tailgate when lowered.

That is, If you have the correct model.

The pioneer tools can touch it, depending on who made them.

No biggie.

I wish I took a picture but this is from memory. It seems the mount is on the outside of the cross member making the pintle stick out an extra 1/2". Seems like it should be on the inside.

Got to take pictures next time?!!!

Looks like the previous owner assembled it incorrectly.

Seems like the mounting plate should be inside the cross member.

You're correct, it belongs inside the cross member.

At least the fix is just nuts & bolts, better than something done with a torch & welder...

Ok, thanks for the confirmation. 4 bolts, cotter pin, big nut! I can do that!

With everything found out over the last 4 weeks I will suspect everything on this truck as being installed incorrectly.
Oil pump 180deg out
Distributor, not in sync with crank
BIG, I say BIG, vacuum leak where the wiper tube was not plugged

I think previous owners do all those things to ensure we become very very well acquainted with our trucks!

That is quite common with ex-military vehicles: They are designed to include many differences from civvy trucks, such as electrics, lighting, and bodywork.

What I never understood why so many just ruin the vehicle to turn it into some Frankenstein thing. Cripes, just buy a civvy rig and leave the poor truck alone. Pretty soon, there will be no originals left.

One last item that seems to be missing...

Where do the safety chains attach to? I see a couple of plates but unsure if they are correct.

Is the plate attached to the crossmember or sandwiched at the pintle?

Pictured is a MUTT pintle. Trailer chains to the M37 went to the tow shackles when I was serving in 1977.

Correct. The tow shackles are inside the bumperetts.

Get yourself a set of TM's for your truck, it will explain a multitude of questions.

Or you can download them for free from Steelsoldiers.com
