Driven front axle options?

[WhiteWolf McBride]

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.

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.

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.

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 .

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,

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 :

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.
