Great idea! Congratulation Sunmint1.

On the second version, you use the part 4185 (peeron reference):Technic wedge belt wheel.

Maybe you could use the part 60483 (peeron ): Technic beam liftarm with hole and axle hole to limit still the dimensions.

Good work!

@DurianObried

Hi, Durian. Thanks :)

But... since the part 60483 is not a 'thin' part, the module suffers high friction.

The idea in the second version is to find "the least friction point in the part 87082(Technic, Pin Long with Friction Ridges Lengthwise and Center Pin Hole)

You should use the cross part, the name is Technic Pin Joiner Round with Four Bars 1L (48723) . Thats what i use for my strong u joints.

Thank you for advice.

Does the part(48723) endure enough torque for normal situations such as 1kg vehicle with 30Ncm drive ?

[Zblj1987]

@sunmint1 I think its strong enough.

@Zblj1987

Thank you. I will try some time with your suggestion :)

Anyway, I have no experience in building 4WD PF vehicle yet.

And so, I am following your instruction on your TrialTruck version 9.

Your TrialTruck and Sariel's Wrangler will be good tutorial for me.

Thank you very much for sharing your ideas, works, and instructions.
