I ordered an M18x1.25 die to repair the threads on the alternator. I could have just re-cut the threads to a more common size. In most situations, I would have done that, but I decided against that in this case since I don't want the pulley to be at risk of slipping under a heavy load. I need...

Ah ok, thanks for the replies. I love me some dual exhaust, so I was just curious.

I have a quick question regarding the exhaust on the M1009 CUCV. Did they come factory with true dual exhaust? I got my CUCV about two weeks ago, and it has true dual exhaust. I've been doing research and I haven't found any information regarding factory exhaust for these things. Did someone...

I see that my oil cooler lines are damp in the same crimps, so I'm replying basically to bookmark this thread for my own reference. Thanks to those who have provided part numbers.

Excellent, thanks for the quick reply.

Speaking of... I plan on doing the resistor bypass as well. The 12v junction that's on the firewall above the relay, is it constant hot? Or is it only hot KOEO? If it's constant hot, then I imagine I would need a switch in that circuit as well. Right. I imagine the best way to do it is to cut...

I'm wondering the same thing. If you just cut the output supply from the resistor, and power the GP relay from the 12v junction above it on the firewall, does the GP resistor block still get 24v from the other side? If so, then I can see where this could happen. But if the supply into the...

As far as I know, if you're pulling 25v at least on both alts, your driver side alternator is not on an isolated ground. This can cause some serious issues with the charging system. The driver side alt should be pulling 14v, and the pass side should be about 28v, if I'm not mistaken. I'm new to...

If it comes down to it. I'll try to find a die tomorrow at work. I'm almost certain I can since this is a former military truck after all.

So it turns out I need an M18x1.25 die to repair the threads on my alternator, and I'm having a helluva time finding a die in that size. The various tap/die sets at Harbor Freight didn't have that size, and the auto parts store didn't have it either. Hopefully there is one in the motorpool...

I was rebuilding one of the alternators last night, but the reinstall has been postponed. I screwed up the threads on the rotor and pulley nut, so now I can't fix it until I take it to work tomorrow and (hopefully) repair the threads! It sucks. The nut I'm not too worried about - I can find...

I'm rebuilding one of my alternators with the 27si kit from ASP Wholesale. I'm unsure where the new capacitor (pn 46-1106) is installed in this kit. The old capacitor spans from the bottom to the top of the alternator, whereas this new one looks like it only fits from the top to the bottom of...

Indeed to all of the above. It's an easy heater core R&R. I haven't done one in a CUCV but I have done them in early Chevy trucks. Easy job. MUCH better than most other vehicles, that typically require dashboard removal.

Very nice! I just may have to do this myself (since I'm also a welder).

This weekend I'll be rebuilding the bad alternator and swapping them back to the original spots (I swapped them the other day to get it running enough to drive daily). After that it's a lot of small things. Inspect GPs and GP relay circuitry; inspect GEN1/GEN2 light circuitry; replace the...

Sure thing! PM being sent. I don't know any other CUCV owners around here, yet.

Nice! I'm assuming the seats bolted right in?

On my '86 M1009... I've owned the truck for a week and I've had to put a new radiator in it. The OE radiator had a horrible internal ATF leak. The trans was about 4 quarts low as a result. Cooling system and tranny - good to go. Now onto the electrical gremlins this coming weekend.

Thanks for the warm welcome guys. Yes, Fort Campbell is an interesting place... the area isn't too bad though. Eh, unlikely. A lot of sources on this site say that converting is for the most part pointless, and the 12/24 system is very effective once the kinks are worked out. As of right now...

Hey everyone! I just had to join up because the vast wealth of knowledge on these forums got me hooked right from the start. Last week I became the proud owner of an '86 M1009 CUCV. It has a few electrical faults, and my research led me to this site. I'm glad it did. Long story short - I'm in...
