Scott,if you mill the hexs (thinner) & do a little grindin on the rim.You can bring the wheels in even closer. But be careful,if you go to much,you'll be into the tierod arm. It really makes a difference.

With these two you can run super singles w/out dickin around.
Now TLT.

since I just came across this thread again and it’s a sticky one ,
I figured I add this here :
Example of the use of a TLT-1 axle in one of my 6WD projects:

SmallHaul,the carson front diff is like $200.:eek:
For the same price you can get this.
http://i301.photobucket.com/albums/n...mppics4229.jpg
But! Now you have to buy a set of semi rear diffs to match the front. The rear diff that comes w/the front is two wide for semi. But you can't beat the look of these babies.

The carson is like 2mm narrower than rc/channel.
http://i301.photobucket.com/albums/n...mppics4230.jpg
The carson I was purchasing from pmd. But surf a little & you can pick them up a lot cheaper.
Hope this helps!

So are these Carson axles?

can some one tell me what to use on the input shaft for an axial trans. that im using for a transfer case to go to 5mm so i can build my drive shafts? the shaft on the axial tranny is small and threaded i guess i should cut it off and grind a flat end on it?

Just like you said Shane cut it off and grind a flat.;)

Those are stock king Hauler mud flap brackets with springs so they work like the real mud flap brackets.

Re: Driven front axle options?
 
thanks for posting the info on this thread, its helped me a lot. I'm making a 6X6 tipper (in UK terms)
Already got a Carson Truck Puller motor so dont need a reduction box. Instead I'm making a drop down gearbox using two of the big gears out of two spare Electrifly GD gearboxes, ( GD600 I think).
We will see how it goes!

How wide is the front drive axle? And would a axial axle fit?

WhiteWolf McBride 03-02-2013 09:45 AM
Re: Driven front axle options?
 
This was asked of one of the axle brands, but not answered:

What about a 'throughput' front axle, like the forward unit on the dual-rear-axle semi's. Does no-one make a simple off-the-shelf unit yet, instead of us having to buy ones with metal casings at $150 and up?

I know Joe and Willy DIY'd them a while back, but isn't anyone even making a ~kit~ for those of us with minimal tools?

Only Robbe really makes one 'off-the-shelf', and I honestly don't like their axles when compared to Tamiya ones. Dislike 'em enough to ditch my 8x8 'Panther' chassis if I can do it with Tamiya parts (and they AIN'T cheap)

So, guys... is there a way for us Neanderthals?

It is not that hard. Buy a TLT axle Kit, extra pinion, and axle housings. Then just trim the two pinion halves to fit together. This has been done in a few threads here on the forum. All you will need for tooling is the normal tools to assemble an axle and a hobby knife for the mods to the axle housing.

Here is a pic of a set of TLT's used that way. He is using them as steerable rear axles but it is still exactly the same.

Re: Driven front axle options?
 
Travis: (or whomever has done this, like Willy & Joe)

What about the flanges on the axle casing? Do the casing halves that are being used have the flange/edge that overlaps (malke side?), or the other one? I ask as if it needs removal, it can be used as an alignment assist, right?

As for 'alignment', to assure that the 'throughput' pumpkin matches with the central piece, and the gear-mesh inside is ok, you just bore out the screw-holes (as you'll either have two bottoms with no access, or two tops with no thread to grab), and use long bolts and nuts instead, and it'll line up sufficiently well?

If no-one has done a good step-by-step, mebbe I should do one when I do it, for the archives and all that, hm? If there is one, this is a ~great~ place to put the link to it.

And lastly: how well do the TLT & Semi axles compare width-wise (assuming the same rims/tires all around) and gear-ratio-wise? I don't want a nasty issue with a semi rear end, mismatched to a TLT front (Can you put the gear-guts from one into the other and vice-versa to maintain ratio?)

Sorry for all the questions, but when I get onto sommat thats been bugging me for years, I tend to run with it.

Yes they are fanged and that is why I said you will need the hobby knife. Only one flange needs cut off the other will be for alignment.

You will be using two identical pieces molded with the same holes so alignment will be no issue.

If no-one has done a good step-by-step, mebbe I should do one when I do it, for the archives and all that, hm? If there is one, this is a ~great~ place to put the link to it.

It is a simple mod and you are only trimming one piece to make it so there is not much to show.

And lastly: how well do the TLT & Semi axles compare width-wise (assuming the same rims/tires all around) and gear-ratio-wise? I don't want a nasty issue with a semi rear end, mismatched to a TLT front (Can you put the gear-guts from one into the other and vice-versa to maintain ratio?)

The TLT, tractor truck, high lift, cc01, and cr01 all use the same gears. With the same rims on a TLT and a semi axle the TLT will be a lot wider. You will have to be creative to get the offsets of the rims to work.

Sorry for all the questions, but when I get onto sommat thats been bugging me for years, I tend to run with it.

No cutting required . You just use the male housing (no lip ) part from a straight input/output rear axle and replace that with the non-input/output housing on the TLT-1 axle . Plain simple bolt on .

You right Willy I was just giving the option to do it from available parts from a place like tower hobbies who doesn't carry the semi axle housings. But you right if you have the other housing there is no mod needed just bolt it together.

As for the rim-offset , lock at my Krupp ( at the bottom of this page )
You use the rear inner rims as front rims

Willy:

My imagination, or is the front actually a little narrower than the outer rear axles? As I've got a semy with stock rear width, it'll help me tell if the deed
is not only do-able, but would look decent enough under the body...

Thanks for the assistance,
WhiteWolf

If you get 2x TLT-1 axles and 2x center axles ( from a 3 axle truck ) , then you have all the parts for the swap without having to purchase the extra axle housing ( a-parts 0005467 + pinion-gear ) , since then you just use the left over housing half from one TLT-1 axle and fit that as last rear axle . In that case you also would have to do some cutting , but not that much , to fit it together .

The fronts line up with the outer rears . Its just an illusion from the angle how that photo was taken . For a better comparison here with a King Hauler body :
all-wheel-drive rig , but with bigger and wider tires .
Therefore the front tires stick out from the fenders ( and the rear is much wider as stock )
http://customrcmodels.com/Trucks/new_6wd_project.htm
with stock semi-rims and tires they would be just covered by the fenders

here is a good photo from Travis's Mack :

Re: Driven front axle options?
 
Is there a driven front driven axle with remote locking diff and complete disconnect? Or are they all open and locked only?

I have setup some wedico metal axles that can do this and it is a nice feature.

Der Getriebedoktor refurbish Tamiya axles. A big pluss is that you don't have to buy new rear axles, since they have the same gear ratio.

If you want to spend som money, these are awesome: http://www.wtbcar.com/shopping/index...product_id=192

So both of these axles have 3 positions...locked diff, open diff and disconnect front axle from being driven?

I don't really see how the guy that mods the tamiya axles could completely disconnect the front axle from being driven/powered? I have it bookmarked on how to to lock and unlock the diff.

The second link looks like a Lesu axle (maybe re-branded?) and going by the photos i have found it looks like it just locks and unlocks the diff and does not completely disconnect the front axle from being driven.

It would be nice if a tamiya tlt axle could be converted to work the way that i want it to.

Re: Driven front axle options?
 
Well here is my experience with a disconnect for the front axle. I have a dump truck with a TLT for a front axle and an RC4WD 3 speed. The 3 speed is only rear output in 2nd and 3rd gear. In first gear it engages the front axle. Steering with a load sucks in 2nd and 3rd with having to push the front axle around turning the diff and drive shaft (this is where the disconnect in the axle would come in handy like Small Haul mentioned). So I find myself driving around in first most of the time. From then on after building that truck I just made them full time all-wheel drive.

Agree on all accounts and good informative post. That is cool that the rc4wd 3 speed disconnects the front axle in first. Do you think it is as strong as the stock tamiya trans?

I guess a compromise would be a disconnect trans or transfer case and a lockable front axle.

Does anyone have first hand experience with the lockable Lesu front axle? Is it durable and function well?

It is good trans and just to be clear it is only disconected in 2nd 3rd. 1st is the only gear that awd. One thing thouh it is best to open up the trans and take out the shift springs and relye on the servo to hold each gear as the springs are way to stiff. It take alll a high torque servo has to shift it. Unlike a tamiya 3 speed you can shift with your finger you can't do that with the RC4WD 3 speed.

Thanks folks for much useful information. I as well was debating placing a powered axle on the front of my King Hauler. I bought it used, & plan to hack the sleeper off, & build it into a logging truck. I think the addition of powered steer axle will make it more functional.

Hello Travis, I am a green horn to all of this it is very incredible the work you guys do, I have been looking for information to find a Mack style straight to try and build a 6 x 6 lube fuel RC truck, we just completed the real thing and would love to have a small one, any help would be thankful
