Mine don't click at the end , why is this? They just stop
-
Very nice,what is the clicking noise when the arm goes fully extended , is this much power making gears slip?
-
Very nice,I like the trailer,is there much to building it,or maybe a flatbed the same for the rear of the truck :)

8043 with pneumatics in the video really sucks.
LAs are best for its size and functions.
Pneumatics have other use, but not on this set.
Ye there handy for opening and closing doors ha,hope the new unimog has big changes to live up to 8043.
Look also at that digger above it's movements are very bad no at all realistic and moves to fast,8043 just looks and moves more realistic.
-
This looks really crap to be honest comes know where near even a standard 8043'pneumatics are not suited and way to short,
-
Has anyone made the crane truck full functional RC machine yet? I havnt built mine yet but I'm just wondering is it set up just to fit motors to drive it and steer it?
-
Lithiums are great I'm using them now, there cheaper on eBay too,
-
It is annoying tho,I might disassemble the arm and rebuild again,iv tried swapping around joints but it's still the same,my joints are right beside each other all the time and sometimes it's smooth but if I reverse movement then of dipper arm or bucket both joints seem to meet each other and start clicking ;(
-
I find that being a purist can sometimes help creativity by forcing you to solve a problem using only what Lego provides. I am a 100% purist but then I am so tempted to make some longer pneumatic cylinders and some gearbox parts right now!
u really need to let go of pneumatics ha, la,s are the new way forward , pneumatics are only useful on very limited models unless they redesign the whole set up as there just to fast when activated and not consistent at all.I like both.anyway back to topic.
-
I'm still having this problem where my 2 bottom u- joints are hitting each other 50% of the time ,it happens even worse if I use the bucket and centre dipper arm at the same time they click like he'll till I stop one of the movements,iv checked everything over a few times and it's still the same,the 2 bottom shafts also seem to have play in them ,it's very frustrating at this stage as u have to operate it a certain way to stop this noise , anyone shed any light on this ?

Just bought a set of Energizer lithium batteries AA ,works very well now and more amps so more torque,lasts 4-5 times longer as well,more expensive but cheaper in the long run,
Cost was more expensive at €12.99 for 6 batteries.8043 is flying it now :)
-
I agree and I also love my 8043 ,I bought both a few weeks back but still have to built the crane truck yet,I think 8043 looks very well on the rear of 8258 like riens.I'm also considering buying a second 8043 for the b model,I'm glad I bought the truck now because there now all sold out of shops in Ireland lately and I got one of the last on the shelf!
-
Yeah place some more picts of youre truck m8 always nice to see ideas from others thnx !
Very nice rien looks very nice, have u any pics of the flatbed u built on the back of the truck as I'd like to do the same for the excavator ,it looks very nice on the rear.
-
Is it not true that energizer lithium e2 batteries are the best all round,they look good in the graph above too,wonder would they be good in 8043?
-
As above what's the best around for power/long lasting for me 8043?
-
I like the B model looks good with the panels too,anyone have this built yet ,must be powerful I'd say!
-
Happy new year everyone and all the best for 2011 and bring on the unimog ha!
-
Does anyone else have this problem?
-
No mine do touch some times cause they are right beside each other, if I work the bucket and centre arm at the same time they hit every time too and make a enoying noise ;(
-
After doing this mod it's better but I'm having a problem where the 2 bottom univer joint that are beside each other near the bottom of the arm seem to hit each other and makes a clicking sound,anyone else have this too?..

The tracks moving when the cab rotates is an unavoidable consequence of having the track power go through the turntable. As the cab rotates, it's turning the axles that drive the tracks. The way to minimize this is to have as much of the gear reduction as possible done after the drive passes through the turntable, which the excavator does reasonably well in stock form. Jurgen's Ultimate 8043 improves on this by moving more of the reduction gears into the base.
The cab rotating while driving the tracks shouldn't happen, as the cab is driven by a worm gear that can't be back-driven by torque from the tracks. This effectively locks the turntable in place when there's no power being applied to the motor that rotates it. Does it rotate continuously, or does it move a bit and then stop? If it only moves a short distance, it's likely due to the slack in the gearing, which isn't really avoidable and is made worse by the worm gear drive.
*EDIT: if the cab moves slightly one way going forward, then moves the other way going backwards, you might try reversing one of the bevel gear sets under the turntable. Test it to see which track changed, then flip the black reversing switch on the remote that drives that track so the controls still work as expected. If both drives going through the turntable are turning the same direction when moving in a straight line, that will try to turn the superstructure. If they are moving in opposite direction the torque should cancel out and it should move less.
The one thing that really bothered me about the stock model is the large amount of slack in one of the track drives resulting from the combination of clutch gear/drive ring extension/drive ring/clutch gear that transmits power through the turntable. I replaced that assembly with a differential, which made a huge improvement but required a bit of modification to the area where the turntable mounts to the superstructure. The gearing is the same because I replaced the 16t drive gear/16t idler with a 24t drive gear and 8t idler to drive the 24t end of the diff, and the 16t end drives the original 16t gear in the track base.
It only moves a small bit while driving maybe 3mm to one side but then stops so it's prob as u said just down to slack in the worm gear,I'm not too worried about it ,I'm very happy with the model ,the centre la is a bit slow out near full extension but that's all,I might oil all the gears now with virgin olive oil,might modify it at some stage but I'm happy at the moment.
-
Iv just finished my excavator and I have to say I love it , new la,s seem to work well as it's not that slow,only small thing I notice is when I'm rotating the cab/digger my tracks seem to move very slightly some time too,anyone see this problem,also if I drive in a straight line the cab moves slightly as well,anyone notice this as it's very slight?
-
What are the new 16 tooth gears people are talking about has anyone pics of the new and old,I'm half way through my 8043 built and it's great :)
-
I think the most people just want pneumatics again, after so many sets whit LA's. I think they don not want no LA's any more, but less.
I like both, but I think LEGO should vary more.
Yes I totally agree that both are great in there own ways,with this unimog it looks like the rear bed might tip too,maybe with an La!would be nice to see both in the one set for sure.will it be possible to get the unimog before aug 2011 cause that's a long time to wait ;(

It's not low voltage cause with new batteries it never done it,maybe it's the new la,s
