Tamiya TXT-1 parts compatibility with other

[TenzoR]

I was lucky to score a fair decent condition TXT-1. As I'm going through disassembly I noticed several screws are definitely worn and rusted and chances are I won't be able to get them out with damages to the plastic parts. Since this is my first MT so I'm quite a newbie when it comes to the Clod/Bullhead/Juggs parts compatibility. Would there be a break down on what I can use/source from other MT?

 

So far I think all the tires and wheels and hub assembly seemed to be the same. The Jugg axle and gearbox might be the same. Am I missing anything else?

The TXT-2 is a current model so most spares should be available - all the drive train parts (axles & gearbox) should be the same. Some of the TXT-2 parts are moulded in a reinforced plastic so they should be stronger.

The Clodbuster and Bullhead are completely different trucks, only the tyres and knuckles are the same (TXT-1 wheels have more offset).

Avoid Juggernaut 1 parts, the axles are slightly different and prone to self-destruction. The axles and gearbox for the Juggernaut 2 and TXT-1 and -2 use the same plastic parts.

If there's anything you're not sure about, just ask. There are plenty of us who own and run TXTs so I'm sure you'll get answers,

Thanks I will check out the TXT-2 manual as well.

Is it bad that I'm already looking at the RC4WD aluminum housing ... 

[IBIFTKH]

Bad? Only for your finances!  

But would those expensive shiny axles deter you from running the truck hard?

If you stick with the plastic axle casings, RC4WD used to make a brace which fitted across the top link mounts and added a bit of strength to a potentially vulnerable area.

Another worthwhile mod is fitting E-Revo drive shafts. It takes a little work, the Revo shafts need to be modded at the gearbox end but it's not difficult. They far more durable than the original Tamiya shafts.

The truck will definitely be ran hard. So any suggestions for durability upgrades will be appreciated.

 

So far I have planned to add full bearings, stainless steel screws, HD servos. Still researching on the braces and will definitely look into Revo joints

I'd avoid the stainless screws, particularly if using socket caps, I prefer to use the black high tensile screws, as they have less of a tendency to 'round out' when done up tight. I can also recommend the revo drive shafts, they've held up against me running my TXT with a 1/8 brushless motor on 4S Lipo. Other than that, I've found mine to be more or less bulletproof, It's a very well made truck out of the box.

Any particular source? I just want something that's a kit so I don't have to figure out which screws to get it. I know there's rcscrewz and hexcrews and Tony's. Not sure which else offer a kit for TXT-1. 

Are you using stock gearbox on your 1/8 brushless? I'm going easy and probably going to end up using brushed power.

i bookmarked this some time ago. maybe it is of interest/help:

Sorry, as I do a lot of scratch building I just tend to M3 screws in packs of 100 at a time in various lengths, and then just dip in when I need them. With regard to the gearbox, I've got a custom made box I built myself, but it uses stock gears, so a stock box should be fine. I redesigned mine to get improvements other than just robustness, I did a couple of build threads on installing the motor:

Must admit, it doesn't seem like 3 years ago I made this....

Very cool. I will definitely implement some of these suggestions. They seem easy enough. I can't wait to see how this monster truck runs compare to the Lunchbox.

To save you getting caught out like I did, the TXT1 wheels also have larger locating pins moulded into the back of the wheels than on the Jugg/Clod/Bull..

IIRC, the plastic drive hubs on the TXT are also wider that the Jugg/Clod/Bull, so I guess the metal axles that go through the steering knuckles are longer as well.. Maybe its the hubs that make them wider and not the offset of the wheels??..

[TenzoR]

Well everything is mostly taken apart. I'm not sure what the last guy did but he put something in the diff to lock them so I have to carefully chisel them out of the gear. Other than missing the rear bumper, it looks like it's fairly complete. Now for cleaning and re-assembly. Still trying to source a screw kit. 

Also, I noticed the gear and drivetrain, axles has quite a bit of movement, should I use shims to remove the play? For my touring car, I tend to shim out any plays but not sure if it's required in this application.

I run my Txt -1 pretty hard and snapped a couple plastic axle housings.

I did look at the axle supports, but the servo mounts on axle were cracking the axle housing too as I run 4ws.

I took the plunge and bought the RC4wd aluminium housings, been fine ever since. I went for the ally axles for durability. Very well made item. Fit and finish is first class.

Still in pieces as I await parts to arrive. I ended up ordering all new plastic parts, tires, bearing sets, bunch of 10.9 hex steel screws (couldn't find 12.9 at the small quantity i wanted), traxxas shafts, txt2 optional aluminum dampers. Last piece of the puzzle is the servo mount. In my mind, I think the stock setup will probably not be that durable as the servo mounts are soft plastic and it's mounted to a reinforced plastic piece. I saw the Xtreme Racing servo carbon plate but I don't like the idea of modifying the plastic pieces to accommodate it.
