I've choosen a scale of 1:16 and needed to go for different tyres. What tyres are you looking for? JB

Hi! Some modifications to my version of the Xerion: 6 Motors (2 x XL for driving, 2 x L for functions, 2 servos for steering) Steering: front-wheel, 4-wheel and crab walk Functions: Cabin: lifting and turning rear PTO compressor front lift: pneumatic driven 3-point hitch: pneumatic driven pneumatic connection for trailers SBrick for controls DSC_0099 by JB Technic, on Flickr Lego Xerion SBrick Kompressor Tank by JB Technic, on Flickr Lego Claas Xerion with SBrick by JB Technic, on Flickr Xerion Back 3-Point Hitch by JB Technic, on Flickr Lego Claas Xerion JBTechnic SBrick by JB Technic, on Flickr JB

Look on tue 3rd picture, right next to the rear wheel...there are 2 smiling at you JB Look on the 3rd picture, right next to the rear wheel...there are 2 IR receiver smiling at you JB

Thumbs up! :-) Like the two servos ;-) JB

In my opinion you can swap the blue ones with black ones. I wouldn't swap a blue one with a gray one...on my Xerion I swapped a gray one from the steering with a black one just to have a more rigid set up. Tolerances add up, leading to a wiggly set up. Unfortunately the 2L black pin with pin&cross axle is friggn expensive. JB

I installed an air tank underneath and a pump for the supply at the front. That way I have air for the hitch and 2 air circuits for functions on trailers. https://m.flickr.com/#/photos/135236852@N06/23793564283/ Regards JB If link doesn't work, search for lego xerion JBTechnic on Flickr.

@Technicjb Thanks! I used two servos for steering and two Xl motors for driving. I planed to use a similar concept like on the 4x4 offroader with a servo and an extra motor to select the drive mode. I thought that if I have to use 2 motors anyway I'd go with two servos. So I got 2- and 4 wheel steering as well as the crab walk. For driving I have choosen 2 XL motors since I need enough power for trailers and/or other aux. I put 2 L motors on each side for lifting and turning the cabin, driving the compressor for the pneumatic functions. And I got a drive shaft to drive functions on trailers. I used the battery pack from the Lego train and put it under the hood up front. That way I could keep the hood slim compared to the TLG one. JB @Technicjb Thanks!

Good idea! Got a servo under each axis, pretty packed. Thinking of using a small linear cylinder fofor the front hitch...for this I think I do have enough space. Lego Technic by JB Technic, auf Flickr

Hi! I tried a pneumatic 3-pt hitch on my moc, pretty tricky since the cylinders are not the right size:

Very nice bike! Like the tyres! Are they original? JB

I agree, smaller rims will look better. Difficult to find...couple of threads I posted some links to shops. JB

I do not have the Volvo. But looking at it, GMade Bighorns might be a good choice. What tread pattern are you looking for? JB

Nice choice! I am planing a Fliegl ASW 391. JB

Hi! I don't think that you will find a straight scale....based on the wheels (107,4 mm) I came up with a scale of approx. 1:19 I tried to realize 1:16 on mine... http://www.eurobricks.com/forum/index.php?showtopic=114518&st=75 JB

Absolut cool MOC! Thumbs up! Are you planning to use bigger tyres on the front axle? JB
