Rodeown Posted February 1, 2012 Posted February 1, 2012 I just had a 20 mins to spare and was appreciating my Logging Truck when i decided to see what it would look like with double rear wheels, bear in mind this was just a looks test and not a structural mod, it would probably need the wheels stepping out 1 to get enough strength to make them solid especially on the front set with the differential. But I really like the double rear wheels, think i am going to have to order 4 more for this baby! the original design is below Quote

It is quite obvious that this model needs dual rear wheels, and it even looks like the designers intentionally left plenty of space next to the frame to add them. It looks so much better! Quote
Rodeown Posted February 1, 2012 Author Posted February 1, 2012 there is something else bugging me about this model aswell........ The cog that drives the turntable gets in the way of the logs been loaded on the back, I need to see if i can mod it to move the cogs to the side of the platform instead of behind it. Quote
gilby Posted February 1, 2012 Posted February 1, 2012 my suggestion for the cogs getting in the way is to move the log bed up to be over the top of the cogs... that said trying to move the cogs would be fun to... Quote

Ha Ha That is funny Gilby i was just considering raising the log bed a stud myself.... not sure what to do now. Quote
gilby Posted February 1, 2012 Posted February 1, 2012 well like i said moving the bed is the easy solution... moving the cogs is the technic solution. Quote
BobBongo1895 Posted February 1, 2012 Posted February 1, 2012 In my eyes the same as with the 8258, why didn´t spend TLG double wheels for the rear? It can´t be a real cost intense part. Quote
Pauger Posted February 1, 2012 Posted February 1, 2012 (edited) In my eyes the same as with the 8258, why didn´t spend TLG double wheels for the rear? It can´t be a real cost intense part. There is a problem with this, and it's caused by the new diffs. Because the drive axles are only mounted on the 1/2 stud 12t gear they will constantly fall of as long as there is nothing else to keep the axle fixed. In this case there wouldn't be room for it if you don't want to make the rear axles wider. Generally though, they don't seem to prioritise dual wheels whatsoever. And if I rememember correctly; authenticity is part of the holy trinity of technic bulding in TLG. So it's pathetic, really. Edited February 1, 2012 by Pauger Quote
Blakbird Posted February 1, 2012 Posted February 1, 2012 In my eyes the same as with the 8258, why didn´t spend TLG double wheels for the rear? It can´t be a real cost intense part. Actually they are cost intensive parts. 4 more wheels and tires would cause a significant percentage increase in the price (I'm sure at least $10, probably $15). LEGO Designers have to meet very stringent cost targets and balance part count against those. Since this is targeted at kids and most kids won't care if it has 6 wheels or 10, I'm sure the extra cost could not be justified. Personally, I wish they would offer "upgrade packs" to interested buyers. They could be directed marketed and it seems like they would be pure profit. For example, this model's upgrade could include 4 more tires, more logs, and possibly other accessories. 8110 is even more obvious since various additional attachments could be offered. I know I'd buy them. Quote
Rodeown Posted February 1, 2012 Author Posted February 1, 2012 Hee Hee i go to do something else for a while and come back in the room and my wife decided she was gonna add a sleeper cab to the truck, I told her they wouldnt have a sleeper unit on a logging truck but she says she likes it lol.

timslegos Posted February 1, 2012 Posted February 1, 2012 Nice mod. I agree it definitely looks better. Any other mods planned? tim Quote

The did substantial advertising for the technic range regarding adults in germany, it could be a real market for such xtra products. @Rodeown, I like the cover of the BB.

Maybe you could use one of the Black Bar 9 x 13 Grille, to kind of protect the turntable and the cog, 8049 Tractor with Log Loader contains one of these! Don´t know if it fits, but give it a try! fitzi Quote

Don´t know if it fits, but give it a try! fitzi I could...... but looking at it there should be enough room in the chassis to come up with an under bed solution I think, I will give it a go but if all else fails I'll fall back on your suggestion Fitzi :-) @Rodeown, I like the cover of the BB. BB ?? Sorry not up with all these technical terms yet, only just found out the other day that I was an AFOL. Lol :-) Quote
Rodeown Posted February 2, 2012 Author Posted February 2, 2012 BB= Battery Box Doh! *slaps palm of hand to forehead....then creates lego technic gun to point at own temple and shoot what little brains he has all over the floor!* There is a problem with this, and it's caused by the new diffs. Because the drive axles are only mounted on the 1/2 stud 12t gear they will constantly fall of as long as there is nothing else to keep the axle fixed. In this case there wouldn't be room for it if you don't want to make the rear axles wider. There is a very simple solution to this that came to me whilst sleeping last night, nothing on the existing differential and wheel fasteners needs changing apart from the center axel changed from a 7 to an 8 and then the wheel nearest the chassis needs turning round 180° so the hollow of the hub goes over the axel holders then the outer wheel goes on as normal, doing this will step the wheels out by only one stud. then add another mudguard piece to the existing one and voila! Double wheels that wont fall off. I will do the mod later just to check it and take some pictures then I will order the parts I need if it works. Quote

Actually.. if you want to be really anal (like me) it is possible to keep the initial width, but then you have to ged rid of the 15L beam outside of the diff bracket and swap the 3L liftarms on the wheel mountings with 2L. Then you'll end up with double wheels, which keeps its initial width and doesn't fall off. You'll also have a problem with the structure around the diff because of the missing beams... to difficult for me to explain, but entirely possible to fix. Edited February 2, 2012 by Pauger Quote
Rodeown Posted February 2, 2012 Author Posted February 2, 2012 I did some test modding on the rear wheels today and did a video of it so you can get a better idea of what i am attempting, I would appreciate any input or suggestions off you long term technic builders please Quote
efferman Posted February 2, 2012 Posted February 2, 2012 i have a question, how wide is the truck at the stabilizers when they are in driving position? and is this the widest point of the truck? Quote
Rodeown Posted February 2, 2012 Author Posted February 2, 2012 (edited) Approx 165mm wide and yes that is the widest part of the truck. Just measured the rear wheels width in standard and they are 130mm wide each wheel is 20mm width so if i was just adding the wheels it would be 170 wide only 5mm wider than the stabilisers, but as the inner wheel gets turned it moves it in 10mm so with the mod done it ends up been only approx 160 mm wide with the wheels doubled up. Edited February 2, 2012 by Rodeown Quote
efferman Posted February 2, 2012 Posted February 2, 2012 roundabout 19 studs? if yes i suggest you to use my tandem Axle and wide the the front hinterachse von efferman auf Flickr Quote
DLuders Posted February 3, 2012 Posted February 3, 2012 @ Rodedown: I think that your dual rear wheels mod looks fine! There are quite a few Peterbilt 379 logging trucks on the roads here in the Pacific Northwest, and the mod you did looks more realistic! SAR BOY's Flickr photoset has 32 pictures of them, and one can see that the rear "track width" can be a bit wider than the front axle's track width. If you look at the mud tracks in the picture below, it seems that the rear track is a bit outside the front track: Quote
Rodeown Posted February 17, 2012 Author Posted February 17, 2012 Thanks DLuders, i got my new/secondhand wheels today so have installed them. one thing I noticed was that the older wheels have a spacer inside them so when i put them on the inside it holds them off from catching on the wheel bracket so no more mods need doing other than changing the length of the axels. I did do one other mod and that was to the wheel guards still not sure if it looks better with them or without? please let me know what you guys think. Pictures below. this is it with the doubled up wheels but no mods to wheel guard other side showing how i altered the wheel guard and added 3x 6004888 pieces to hold the light bracket on, this has made the light bracket much more stable than the original mounting. here you can see i have added 2 top bars and T piece to the wheelguards to make it look better? hmm not sure really, i like both on and off! And finally a low down shot looking along the truck so you can see the wheels not sticking out to far Quote
Alasdair Ryan Posted February 17, 2012 Posted February 17, 2012 I came up with a idea, it is not very strong but it does seem to work ok.( Sorry about the Scottish accent ) Quote
