Crawler 9398 MOC

[Denny]

I try to build the new Crawler 9398. But it is very difficult because there are not enough pictures on the net. That's what I see:

Now I need more pictures. And the new PF Motors...

I think you can put a 12th gear to the 20th and inside the 5x11 liftarm structure with the diferential inside again and other 20th gear with maybe a 12th gear...

Denny, you are off to a great start! Looks fantastic.

I think the two 1x11 beams in the above picture should be replaced with this part:

The differential would be inside this, with the 12-20 reduction alongside.

Nice work you're doing here!

[timslegos]

I really like your progress! It is very hard to reverse engineer such a big model.

@dhc6twinotter

That can be, but there is no room for a differential

You have to remove the shocks too the right position is like in the unimog instructions, I think this set is more easy to do that unimog, the only problem are the motors , good luck. Dhc6twinotter says the same that me in the up line but maybe better explained . Remove bricks and you will have room for the 5x11 liftarm structure and the diferential.

what is with this possibility ?

Very good reverse engeneering Dennis!

[Denny]

OK...

[Technic Gearhead]

Off to a great start!

[Denny]

The differential is inside

[DLuders]

Judging by the metric ruler placed next to the chassis above, the 9398 Crawler appears to be CLOSE to the size of the 8297 Off Roader (~25 cm between the front and rear axles):

Has Anyone have any idea how that works?

[efferman]

two 5 L liftarms instead a 11L liftarm?

[Denny]

Or like this:

[efferman]

it seems that we have searched a solution for different problems. do you think the motor above the axle is the drive motor?

[Denny]

This is a very good question. I think so

It has to be. The XL motor with the axle through the center would then be the steering motor.

By powering the front and back axle with 2 M motors gives a lot more driving power.

I agree with this except that i dont thinkg the center motor is necesserily of an XL size, i think it is more of M or L type of motor.. it is interesting looking att these pictures to see that so much gearing down is made from the drive motor to the wheels.

[Denny]

That is also my idea. But it does not fit

[Henkl]

That is why they have build a new one.

Looking at the pictures again, it looks like there are all the same.

On the box there 2 and 1, but that has to be old M motors.

I think you need to replace the middle two grey pins with two 3 long pins with centre hole, you can then mount the suspention onto them. This will give you more room.

[Denny]

With the M-Motor he is very slow

We need the new Motors NOW

Could you invert all the gears ? The torque won't be good, but I'm curious of the total speed/torque.

Looking awesome! I'm guessing the new motors have pin holes on the sides, which uses those pin with bushing pieces to hold it in place. Maybe.
