Frame S/N

[gcbennet]

I saw once on a G503 thread that there is a number stamped on the LH rear frame but i can't seem to find it on my humvee. I'm either looking in the wrong areas or the number itself is obscured by paint, dirt, or whatever. Does anyone know where the exact location is so i can at least get the wire wheel out and start scuffing paint if i have to?

I have stripped many HMMWV frames and in the process of stripping one right now...the only numbers I have ever seen are on the Very rear end of the Frame rails...
where the shackle bolts pass through, if you have an Airlift bumper on the truck, it will need to come off...i was actually looking at those numbers yesterday...I dont know what they are...almost like a date code.

Thanks. I've heard of that location as well as just aft of the rear most LH tie down loop bolted to the frame. I looked in both areas but didn't see anything. I don't have an airlift bumper so i'll start removing some of the paint on the rail cap and see if it's there..

Here's my LH rear bumper. Can i assume this is what you're talking about?

Can't you use the S/N stamped in the body seam above the wiper bottle?

gcbennet, Yes the frame date stamp is stamped right into the rear face of the frame end cap. You will have to get that thick carc off to find it most likely. Some of the numbers may be upside down.

NDT, the body tub number is stapmed there. There is no date code in it. It's just a number to keep track of the body tub. It has no correlation to what serial number was put on the completed vehicle other than possibly the next higher body tub number got the next higher serial number.

Awesome, thanks. The concensus thinks the number stamped on the rear frame is actually the julian date ie. s/n 12685 would be day 126 of 1985 (Monday, May the 6th, 1985). However, some vehicles may have had replacement frame members somewhere down the road in which case the number would not be a true representation of the actual age of the vehicle.

Cheers!

If your lucky remove the front bumper and you might have the original factory tag in the R/H chassis rail
