My LMTV has a Neihoff 1509-1, 100 amp alternator. What other alternators will work on my 3126 with no modifications?

The newer 100 amp unit is the N1511-1 but there are 200 amp and 260 amp Niehoff units as well. There's no direct fit civilian alternator for these vehicles at the moment.

Which 200 & 260 amp units would work?

There's the N1224 Dual Voltage alternator, that's the 260 AMP, it uses a different bracket however

200 Amp - N1216-1
260 Amp - N1224-1
I've fit a N1216-1 on a Cat 3116 so it will fit a 3126. I lengthened the upper armature to ensure good clearance and shimmed a pulley from the 100 amp alternator and it fit. It drove from Kentucky to Idaho without any issues.
N1216-1
N1224-1

Thanks for the information. Is the bracket off the shelf or does it need to be custom built?

I have one off an original engine I can send some pictures, but some people fabricate their own.

If it’s not too much trouble I would like to see the pictures of the bracket.

I have the brackets for the 260/300. I had a bunch of the HIMARS variants spun up. $275
Do you have the v-belt or the serpentine belt setup? The v-belt is a goat-rope but DM me if you want to talk about a kit for that. I know where you can lay hands on one.
The serpentine belt setup you can just use the HIMARS bracket and bolt on the 260/300 units, but you still have to move the upper shock mount out about 3/4" to clear the body of the larger alternator. Cut the huck bolts, copy the existing spacer behind it out of 1/4" plate (x3) and stack them behind the shock mount along with the original spacer and use longer grade-8 hardware to bolt it back up.
Or you can find the replacement shock mounts the Army supplied with the upgrade kits to the 260.
The 100's were very problematic and too small for the battery bank that is perpetually dead in the Motorpool due to vast amounts of time sitting and waiting for training or deployment and it kills them. The 260 (actually a 400 if you rate it like the 100 is rated) is 72 lbs and they are built like tanks. Never seen actually fail. SPC Wank usually just leaves the Nord-Locks out and they fall off the truck.

Thank you for the pictures. I can fabricate the plates to move the shock mount out 3/4" I have the serpentine belt. I would be interested in the bracket to switch to the N1224 Dual voltage. Thanks for the help.

Where is a good place to buy a good N1224? I see them on ebay used. But you don't know how used/abused they are.

I'm the seller on ebay and they're take offs that went through my local Neihoff certified rebuilder. They passed all tests and rated grade B for cosmetic decencies. I believe I have one that came off a crated engine but I will have to check.

I have some freshly remanufactured units in stock, they come with a warranty of a year, Let me know if you're interested. I also have the bracket for them.
@that_one_alternator_guy any kits for a 3116 upgrade?

Unfortunately no kits, I just have remanufactured units and the bracket added on the 3116
