M1070 dump truck conversion

[tatra813]

I’m converting my m1070 into a dump truck. I have all the stuff for the conversion. Before I go through the manuals , there are 2 trailer wiring connections for the fifth wheel hitch. I assume one is for 12v and one is for 24 volt.

There is also one connection in the rear of the truck for the Pintle hitch. Anyone know what the voltage is for that?

Im debating changing out the dump bed lights for 24 v lights OR just using the 24 volt existing Wiring as signal wiring for a relay that sends 12 volts.

Any thoughts on this?

also I believe the truck actually generates 12v and 24v at the alternator. What is the 12v supplying power for?

Im also adding a dump truck style Pintle hitch to pull a tag trailer. I’m also planning on adding a air suspension dump valve.



thanks in advance

Everything in the HET is 12v for the most part. Except the starter and a few lights.

Trailer plugs, 7pins are 12v, 12pin rounds are 24v.

The rear plug is 24v. The truck taillights are 12v.

How is your project going? I have a M929A2 but thinking I'd like to sell it and get/build something a little heavier. Been looking at 7 tons but wondering if your idea of converting the M1070 would be better.

I have heard that the m1070 isnt a great platform for a dump truck due to the air suspension. MTVR would do nicely.

I may have just negated the need for this. I purchased a komatsu CD60R crawler dumper. Basically an excavator undercarriage with a dump truck body. I still like the idea of it though.
