Hi my name is Alexander i live in the Netherlands.

I don't speak French but i hope some one still can help me out. I got this SG car a few weeks ago and i am planning to restore it. It has a super tigre .21 engine on it and 2 old servo's.

I have a few questions.

I dissasembled the car but i don't see how i can open up the differential. Is there a special way? I unscrewed one screw that is in the copper housing but i i can still not open it Does anyone know how to do that? Do i just have to use a lot of force?

The metal pod seems to be bent a little where the epoxy plate is screwed onto. I think i can just make it straight again by hammering it a little?
The gas tank is also missing the cap. Is there a good replacement for it?

The spur is still in good condition but can i get spares from somewhere?

I didn't make any pictures during dissasembly cause the car was very dirty and oily. I will make some pictures of the proces soon.


With regards,

Alexander

Salut mon nom est Alexandre.
Je ne parle pas français, mais j'espère que quelqu'un peut-encore m'aider. SG j'ai eu cette voiture il ya quelques semaines et je me prépare à le restaurer. Il a un super tigre 0,21 moteur sur elle et deux servos vieux.

J'ai quelques questions.

Je dissasembled la voiture mais je ne vois pas comment je peux ouvrir la différence. Y at-il une manière particulière? Que je dévissé une vis dans le boîtier en cuivre, mais encore peut-ii pas à l'ouvrir:?: Est-ce que quelqu'un sait comment faire cela? Ne i suffit d'utiliser beaucoup de force?

Le pod métal semble être un peu Où sont la plaque époxy est vissé échec. Je pense que je peux le rendre droit nouveau par martelage un peu?

Les Spurs sont toujours en bonne condition, mais puis-je obtenir de pièces de rechange de quelque part?

Toutes les images je n'ai pas toujours dissasembly cause de la voiture était très sale et huileuse. Je vais faire quelques photos du processus bientôt.


En ce qui concerne,

Alexander

hi and welcome

a+ tof

to open the diff :

remove the filling screw (if it exist)
the brass tube must slide ... but it's quite hard due to the age of the O ring .
it's often glued

you could heat the brass tube to allow it to slide more easy .
you must not use tools , use rag to prevent burning hands

Hi,
Thanks, I will use a paint heat gun to warm up the ring and see how it will get off. Thanks!

be carefull while disassembling

here the second generation of diff , exept size it's nearly the same construction
as this , you could see O ring

ah yes, the axles where the wheels go on are a little different. From what model did that diff come from?

By the way, how do some of you use the tire truere? Did you make some harbors yourselve? The axle where the wheel goes on has half a cirkel and is being set with a setscrew in the plastic wheel. Not like the one on the picture above.

yeah , that's VCS diff equiped with quick fit , same rims as futura are used less bolt.
it was just to show O ring under brass tube .
did you finally take out this tube ?

i heated the tube with a paint gun, it was so hot that i burned my hand while using a towel to try to get the tube off (towel was a bit damp and steam came off from the towel!). Impossible. It seems the tube is glued with some green stuff. When i heated the tube i could see some very small green bubbles comming out between the tube and the diff body but still i can't slide it. There is absolutly no movement what so ever.

Here you can see some of the green stuff still on the outside of the tube. It seems to be the same as the stuff in between the tube and the diff body

It has been a while when i last posted my progression as i was busy with racing my TEam Associated RC10L2 (pro10) in our national championship and clubrace.

All the parts of my Futura are still in a box but the urge to rebuild the car is comming again. I still could not dissasemble the copper diff tube so i am thinking to just put it in break cleaner or other stuff to see if it will dissolve the green stuff that they used to fix that copper tube. Heating the copper tube didn't help.

Any other suggestions to help slide that tube off would be appreciated

Hello
You could try first the soft method: leave it one or two days in some WD40 or like product, clean it then with alcool, and then try to slide/make turn the cover by gently fixing the body of the diff and using a piece of air chamber to get more grab on the cover (use your hands to turn, not pliers).

If you have heated up that hot, it probably means you have also damaged the O-rings... If you are ready to replace them, leave it some hours in a thinner (orings will be killed). Whatever glue or grease, this should go out.

Another solution I never tried is to boil it in water with some degreaser (beware not to use soude/soda based degreasers, else the aluminium/metal may turn grey.
