@ EM4CZ: I stand corrected -- I was thrown off by the LDD .lxf file's name ( 8404_zametak.lxf ). I would imagine that all of the Czech sweepers are parked, with all of the SNOW you guys have been getting!

@ EM4CZ: I like your mod to the Lego 8404 set's truck (shown in the picture below):

Here's an interesting article on the Rebrickable blog about "2011 LEGO Set Popularity" -- Nathan Thom (Technicmad) wrote: "Inspired by Technicbricks poll on popular 2011 technic sets I have done a quick query to see how his results matched the data at Rebrickable. Based on: * Over 2000 users have stored their set collections * There are 13000 sets released in 2011 in the collections "The top 10 most popular sets based on the number of unique users who own them are: "The top 3 are the same as those on Technicbricks which is no real surprise as they are fantastic sets. It’s also nice to see the Creator/Star Wars sets take out some high ranking positions. "The 8043 Motorized Excavator seems to be the most popular set of all time. At least until the 8110 Unimog comes down in price! It was certainly one of the most enjoyable ones to put together for me. I remember loving my first 8851 Excavator set, we’ve come a long way. "There are also some great mods out there of this set, one of which is Jurgen Krooshoop’s Ultimate 8043:"

[bUMP] I wonder if Nathanael Kuipers' JEEP HURRICANE could be made out of the 9398 4x4 Crawler's parts. They both have four-wheel drive (4WD) and four-wheel steering (4WS). NK's Jeep Hurricane model could not actually DRIVE ITSELF (due to the limitations of available Lego parts at the time), but maybe it could be retrofitted when the orange/black/white 9398 4x4 Crawler is released in August 2012 with the (likely) Power Functions "L" Motors....

The "Crawler" can now crush Lego cars, like this:

@ dokludi: Yes, that's what I'm talking about!

In this case, the John Deere ILS is the "Independent-Link Suspension" -- "The John Deere Independent-Link Suspension (ILS™) utilizes industry-leading technology to supply unsurpassed gains to end-user productivity. This innovative design incorporates proven suspension design with mechanical front-wheel drive (MFWD) axle components that use state-of-the-art technology specifically for heavy equipment usage."

@ Jurgen Krooshoop: Actually, the Power Puller wheels/tires DO fit the Unimog's portal axles. From Barman/ Barman76's Flickr photoset, the combination will work:

This would do the job!

@ craigey: Welcome to Eurobricks! If you look at the various MOCs posted on Rebrickable, you will keep VERY BUSY. All of them have Building Instructions and Parts Lists.

@ jippen: The PDF Parts List for Yoraish's "Little Boy" Lego Technic Rock Crawler has been uploaded to SkyDrive here. I updated the links in my previous posts about this topic, and crossed out MegaUpload.

@ jippen: Welcome to Eurobricks! I'll upload the PDF Parts List onto SkyDrive when I get home from work. I've been re-establishing all of the broken links from the (now defunct) MegaUpload, but it's taking a while....

@ Phantom59: Could you describe the functions of the various parts in your four MOCpages pictures below? How does the locking differential work?

@ I_Igor/ iipsa: Thanks for pointing out your 710-70R38 Agriculture tire folder on Brickshelf (with its 3 HUGE pictures)! "[Real world] Tire overall diameter - 1930mm Tire overall width - 710mm Wheel overall diameter - 1080mm LEGO solution: Tire overall diameter - 114.0mm Tire overall width - 53mm Wheel overall diameter - 64mm In order to achieve 114mm overall diameter from Power Puller tire, you have to put one 94,8 X 44R Balloon tire inside it. Important thing is that you put container block 9 x 9 x 1 at both sides of tire between Power Puller [wheel] and 94,8 X 44R Balloon tire, and then press them using dish 8 x 8, axle 10 threaded and axle nuts.

I would leave the legs the way they are (unless you need the black parts for the head). The proportions are similar to those found on other Lego figures. You could always remove some once the robot is complete. Once you add the head, you may break the glass roof panels in your conservatory! It looks like the final version will be well over 2 meters high!

@ Mahjqa: I like the planetary gear system, and the LA steering for the front wheels. I also like the "show-off" Technic Figure skier being towed behind the vehicle!

Nice job of "reverse engineering" from just a few pictures!

@ scottwb2010: You need to install LDD Manager to create a Parts List from Brickbox's LDD .lxf file above. Try it -- you'll like it!

MacGyvarek has this Lego Technic 8297 Off Roader II set with Power Functions elements for 2WD; I don't know of any Building Instructions to make it 4WD. His Brickshelf Gallery http://www.brickshelf.com/cgi-bin/gallery.cgi?f=358965 has a set of photos & LDD renders, plus a Parts List: Here is the Parts List for MacGyvarek's version of the motorized 8297 set. The part numbers are from Bricklink ("The Unofficial Lego Marketplace"). The "Pimped 8297" version has a Parts List for each assembly at the end of the 102-page PDF Building Instructions that you can download. MacGyvarek's version needs these parts (listed in the order that they appear on the Brickshelf parts image pictured below): 2 ea. 4459 "Technic, Pin with Friction Ridges Lengthwise" 1 ea. 3749 "Technic, Axle Pin without Friction Ridges Lengthwise" 1 ea. 6538b "Technic, Axle Connector (Ridged with x hole x orientation)" [NOTE: 6538 or 6538a will work too] 3 ea. 3647 "Technic, Gear 8 Tooth" 1 ea. 32270 "Technic, Gear 12 Tooth Double Bevel" 1 ea. 32269 "Technic, Gear 20 Tooth Double Bevel" 1 ea. 60c01 "Technic, Gear 24 Tooth Clutch" 1 ea. 4519 "Technic, Axle 3" 3 ea. 3705 "Technic, Axle 4" 2 ea. 32073 "Technic, Axle 5" 1 ea. 3706 "Technic, Axle 6" 2 ea. 44294 "Technic, Axle 7" 5 ea. 32184 "Technic, Axle and Pin Connector Perpendicular 3L with Center Pin Hole" 1 ea. 48989 "Technic, Pin Connector Perpendicular 3L with 4 Pins" 1 ea. 40490 "Technic, Liftarm 1 x 9 Thick" 1 ea. 32524 "Technic, Liftarm 1 x 7 Thick" 1 ea. 32316 "Technic, Liftarm 1 x 5 Thick" 2 ea. 3701 "Technic, Brick 1 x 4 with Holes" 8 ea. 41677 "Technic, Liftarm 1 x 2 Thin" 1 ea. 8882 "Power Functions XL-Motor" [NOTE: Bricklink lists this as Part 58121c01 also] 1 ea. 8883 "Power Functions M-Motor" [NOTE: Bricklink lists this as Part 58120c01 also] 1 ea. 8885 "Power Functions IR Remote Control" [NOTE: Bricklink lists this as Part 58122c01 also] 2 ea. 8884 "Power Functions IR Receiver" [NOTE: Bricklink lists this as Part 58123c01 also] * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * There is also the "Pimped" 8297 (scroll 1/2 way down the list on http://www.bouwvoorbeelden.nl/home_eng.htm to find it). Dutchman "bouwvoorbeelden" wrote, "Yes, you will recognise this model as the Lego Technic 8297 Off Road car. But this is not a normal 8297. It is thoroughly PIMPED! This car has: - a complete new roof with Spoiler, Air Inlets, Antennas and Six Rally Lights - Widened windscreen - Protective Side Bars and extra Bull Bar at the front - Exhaust pipes - A turning steering wheel in a restyled dashboard - Metallic look with Black details instead of grey - Transparent motor block - Two Infrared Sensors in the roof - Two extra motors for remote driving & steering" It has an MLCAD file, a movie, PDF Building Guide, and a Parts List.

@ martinnygaard: On his Brickshelf gallery, gor ipsa/ iipsa has a few pictures of the final model, with this description of the rear wheel construction: "John Deere 8270R with ILS Model is based on real machine with - front tires - 30" group 43 - 600/70R30 (Real tire od 1603mm, LEGO Tire overall diameter on container container Storage X-pod is 94.8mm) - rear tires - 38" group 47 - 710/70R38 (Real tire od 1930mm, LEGO Tire overall diameter is 114.1mm) Any comments, ideas, etc you can eMail to iipsaATinetDOThr ." He also discussed his rear tire construction a bit on this Eurobricks topic. Note that dhc6twinotter used a similar design for the rear wheel on his Lego PF JCB 3CX Backhoe:

Boy, when you say that you "Build Big Stuff", you're not kidding! If you pick up the robot and walk over to your bathroom scale, how much does it weigh so far?

If one could add four large "Power Puller" tires and wheels, the 9398 Crawler would look a lot more impressive. The 9398 is close in size to the 8297 Off Roader, and both use the same wheels and tires. Look at how this "Bigfoot" 8297 (from the Kocke Klub) looks with the Power Puller wheels, and imagine the same effect on the 9398 Crawler:

@ shuoshuoliuliu: In the USA, I can open all three of your video hyperlinks; the second one works the best and has the largest image size. Your 4WD Army Car can sure climb a steep angle! P.S. My father was born in Tienjin, China in 1917. Perhaps one day I will visit there....

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):
