You sure it's JIC and not AN ? AN would make more sense to me in this application, and the tolerances are more specific vs JIC. About 10 years ago we lost power after takeoff in one of the aircraft I flew in after a parts supplier supplied faux AN fittings that were actually JIC. Given that a...

A small contribution to the community (full memo and literature, courtesy of my awesome local Allison rep): It's part # 28 on my SN diagram:

Oh hey, one of suprman's listings (I believe). Picked one up as well. Don't have a nato slave receptacle on the truck but that's easy enough to re-terminate and power with whatever else. Looks like center pin is positive. Thank you so much for your expertise/advisement on this. I obviously...

With NC tax and a mandatory $60 freight charge since Allison is the only place I can seemingly get it (dealers/distributors don't have it anywhere on the east coast, 3 different ones all saying same thing), it's $460. The dude was shocked at how much it cost. Like, he was warning me to be...

Well, you and general disorder convinced me... time to eat Ramen for a month !

I'm going to buy one if I can... but PPA-CF is a pretty incredible filament. We sinter in nylon at work, as well as metal sinter up to 316SS, and I'd say that PPA-CF is somewhere between the two. Has something like 24,000PSI tensile strength, almost exact dimensional printing, great layer...

Wow. That is the most expensive washer I think I've ever heard of... I am now a little bit more prepared for sticker shock when/if the guy calls me back. For that price I'm tempted as well. I wonder how one printed from PPA-CF would perform...

My 2002 A1 also does not have the brace mentioned earlier. No current issues but I am looking into pre-emptively replacing it. Trying to find a place to buy the new P/N 29545936 is proving difficult. Waiting on a callback from my local Allison dealer but not sure Allison even makes this anymore.

Thanks, makes sense the seals are toast. Sudden seal failure at these pressures is definitely possible, just wasn't sure that was the cause. I'll go the 2x pump rebuild route. Just finished reading this thread, found Colt and Fastidioud rebuild videos, and while the individual seals, u cup, and...

I have looked at buying one since I imagine I'll be doing many diagnostics on the truck but based on these forums, the software is the hard piece to find (along with the $600+ pricetag).

Alright, new problem... My cab will no longer raise. The cab will go up a small amount, the pin appears to retract, but the cab doesn't raise more than 0.5-1" we'll say. My wife and I were able to "help" lift the cab all the way up (Basically both of us overhead pressing from underneath the...

Yesterday I was able to finish making battery cables and tried to give her a start Before After. Turned out a little messier than I was hoping, and still need to cut down the length of the charger leads, but it does supply the correct power and the lid closes. Most of the remaining cables...

Neither oshcut nor sendcutsend will bend anything thicker than 0.25" steel, but some quick chatGPT math says a 40# cantilever at the end of 1/4" A36 steel 3" wide and 7" long will deflect ~0.01" at 2.5G. And I can literally order this for $100 shipped, blast 4x crappy welds on the tube and be...

That's awesome you're having an extra 14 made to (I assume) sell to other members looking to upgrade their alternators. It is an interesting design. Skeletonized for weight, easy to make... and I am a huge fan of laser cut/CNC bent parts vs having to weld... Hm. I wonder if a hybrid approach...

Need to physically have the alternator to finalize the dimensions of it, which will drive the protruding post heights, but all the pieces seem easily machinable or cut-able, and weldable. I left 1/16" clearance for welds. Will 3d print it first, after I physically have the alternator, to check...

Jumping back into this project after a too-warm-to-work-outside-summer. Ordered a 250A 24V Brushless J180 Long Hinge commercial alternator (Leece Nevill BLD4102M Idle Pro X), 1x Leece Neville Pulley (P/N K176105263S), and 1x Generic Pulley P/N 247750). Hopefully they ship early next week, but...

Man, this is a great build. Super informative

I also made a slight "mod" to the protective plate for the air tank drain valves. While using an abrasive paint and rust stripping wheel to clean the surface rust off of it, I noticed quite a bit of buildup in the corners. I drilled a 1/4" drain hole in each corner and deburred/filed it smooth...

Was able to get a bit of small tasks done in the evenings this week. The original tank strap rubber isolators were crumbling where (I assume) battery acid leaked. Pretty much corresponded to where the CARC was broken/cracked/bubbling on the tanks. The paint on these bands was some kind of...

Edit: Just got to the part in your YT video where you explain it is for just that ! Video @ 11:24 @Xengineguy is this slotted bolt to help clear debris from the 3/8-16 holes the original hub bolts are in ? If so, much appreciated ! Getting smart on EcoHub installation (reading directions...
