I don't know of anyplace that currently offers a spool for the AMC-20. I'm trying to show that there is an interest in the product, in hopes that Moser Engineering will build one.

The idea is that they will offer the spool in a 33 (35 if possible) spline configuration with custom axles. Currently custom axles are about 150/axle and their spools run about 200. So I'm thinking that they could offer the whole kit for $500 or $600.

Who's interested?

How about a mini spool for $50.

The idea is also to go from a 29 spline axle to a 33 or 35 spline axle.

That sure seems like a lot of money when you can just get a Scout D44 for $100 and weld it.....

Just my $0.02

(yes, I know it will only be 30 spline :flipoff2: )

The problem with them is supposed to be the housing.Just run detroit w/1 piece and call it good.Until you swap it out.

Hmmm...

AMC 20 = 8 7/8" ring gear
Dana 44 = 8 1/2" ring gear

Plus I already have the AMC-20, shaved the housing, trussed the housing, have the gears -- even have a Detroit for it if the spool thing isn't possible. Already committed to Alloy axles -- even if I swapped to a different diff, and it wouldn't be a D44. The only difference in price is the cost of the spool.

So you spent all that money on a AMC20 for 1/2" on the ring gear? Did you know that D44's are $100?

Where on earth are Dana 44s $100??!! You're lucky to even find one around here, and if you do prepare to give your left nut for it plus a few hundred.

I paid someone $40 to haul away two of them. They were still attached the the waggy. They're out there.

What money? I did all of the work myself.

And around here boneyards want about $200 to $250 for a D44 rear. For a rear axle a D44 isn't all that great. If I can get a custom spool made for a AMC20 that will allow me to run 33 spline axles it would be much stronger than any D44 that I know of.

Specifications: (Custom AMC 20 / D44)
RG Diameter: 8.875 / 8.8
Pinion Shaft Diameter: 1.625 / 1.376
Axle Shaft Splines (33 / 30)
Plus the AMC 20 uses 7/16" ring gear bolts instead of 3/8"

- And -

Part: Cost (AMC 20 / D44)
Differential, Complete end to end: ($0 / $250)
Spool or Weld: ($200 / $0)
Alloy Axles: ($300 / $300)
Total: ($500 / $550)

So why would I spend more $$$ for a weaker diff? :rolleyes:

Now if I was going to spend money to get a diff out of a bone yard, I'd go with a D60 and then get the 40 Spline Spool/Axles from Moser.

I got my Scout D44 from the yard with the same gearing as my front D30 for $75. You can usually get whole rusted out Scouts and Waggys for $150 easy. Thats in Maine of course :D

Not in Az... Our vehicles never see salt or much moisture and tend not to rust very much. Plus every TJ/YJ owner in the area seem to be snapping up them D44's, so all the boneyards here know they can get $$$ for them.

I got a waggy AMC20 for next to nothing. Already figured on running Alloy axles from Moser, and figured if I could convince them to make a spool for it, I could get bigger axles at the same time. I mean think about it -- ring gear 1/8" smaller than a Ford 9" (which alot of wheelers run) 33 spline shafts (almost as big as 35, and 35's may even be possible, I have to measure) and an input shaft that's nearly the same size as a D60 (1.626 vs 1.625) plus it doesn't hang down as far. The only thing left is the weaker axle tubes -- which I've already trussed.

My vote goes to the new axle. I picked up a d44 front and 12 bolt rear for $50. I could have also got a spool for $75 from summit if I wanted. They had it on the discound counter. They are out there and you can pick them up cheep if you just look around. For how much your talking about spending you could have an axle shipped down to you and still save money.:smokin: :smokin: :smokin:

You must be talking about a spool for the 44 front cuz i know you didnt find one for the 14 bolt rear:rolleyes: . If you did i want to know what brand cuz i have been looking for awhile and the only thing i have found is a detroit.....
I like my model 20 rear I run the Warn full floater rear and would like to replace the lock right with a spool if it were and option...

i made a custom spool for my AMC 20. i used a good ol lincoln welder to do it with too:flipoff2: :flipoff2:

i think there would be a market for a full spool. there are some people who aren't comfortable with welding their rear ends, but still want a spool.

the coolest idea you have yet, IMO, is the 33 or 35 spline axles in an AMC 20. hell, the 35 spline shafts would make a 20 almost as tough as a 60. are we still talkin semi float here, or would you upgrade to FF along with the 35s?

fyi. You can get 33 spline axles for a Dana 44 as well. (OX and Detroit)

I'm thinking of sticking with the SF axles. I have an AMC-20 apart at home and was doing some measuring. Where the wheel bearing presses on it measures about 1 9/16" So at that end, we'd be in good shape for a 1.5" 35 spline axle shaft.

The question comes at the other end. If we use the stock sized carrier bearing then the thickness of the material where the bearing presses on shrinks to a little over 1/8" The stock carrier measures about 1/4" thick. The Ford 8.8 measures about 3/16". Question is: Is 1/8" enough, being as that the axle fits pretty snug in there anyhow? -- OR -- Can we use a bearing that is the same size OD, but bigger ID? As long as the bearing is rated for the same pressure, I don't see why not. I may have to contact Timken to see what is available...

true, i'd forgotten about that. can you use a standard carrier with 33 spline axles? or do you absolutely have to get an OX or detroit?
*********************
would it be possible to machine the housing out any so as to use larger OD bearings? or would that make it way too weak?

just imagine, someone might start making an aftermarket AMC20 axle! LMFAO!!!:laughing::flipoff2:

Naw, that wouldn't make it a feasable aftermarket kit. It would be alot of work too cause you'd have to fill the bearing cap bolt holes and move them out further and use a larger bearing cap, etc...

ox and detroit are it for 33 spline 44's as far as I know

Ok. Here's the deal:

FSJ AMC-20's have a larger Wheel Bearing than a CJ AMC-20.

Larger axles are possible (possibly even 1.5" 35 spline axles) in the FSJ AMC-20's. The CJ's are out of luck.

Now for the FSJ AMC-20 owners:

Moser won't make the spool. But I have a line on a Machine shop that might. I need to find out what size bearings are available for the carrier (spool). If using the stock size, only the 33 spline axles are possible. If there is a bearing that can withstand the same load, that has the same OD, but a larger (at least 1/8") ID, then 35 spline axles are possible.
