42108 mods and improvements

Hi,

Thanks for the kind words, The modded model I shared has a lot of floating parts so wouldn't be possible to build , I have just this minute finished building the full original digital model in LDCAD (the file I shared above was based on somebodys reverse engineered STUD.IO (studio) digital model.

If you are able to wait a little, I can try to add my mods to the full LDCAD file thus I would therefore be able to give a final addon parts list (some parts that are removed from the original will be used for the mod).

As for the drivetrain, If I made it floating then the drive motor would also need to move up and down as well as the driveshaft and the wheel axles. So instead I am using pivoting axles with suspention. I plan to utilize the 3x3 technic biscuit joints and 7x11 frames as a wrapper for the motors and mechanisms, while being structural to other 'frame exteral' things too.

Regards, Snipe

sorry for the follow-up but i have a question regarding the differentials:

I've loaded the model in LDCad and notice that in place of the 2-part differential there is a red 28 cog wheel 46372 and 2 pieces 98585.

Is this an error on my part or a placeholder ? (i am experienced with CAD Programs in genral but still learning LDCad)

Would this also work with the 62821b differential actually ? (i assume then the 12-cog wheel 32270 would need to be changed to 32269 20 cog but that would change the gear relation then)

Oh yeah I forgot to mention, its just a  representation of the new differential that are in set 42109. The cog in that set has a half pin hole but is not in LDCAD yet. the two gray technic discs are the differential case.

Yes the old  62821b  differentials should work assuming you add 3 inner bevel gears instad of the 5 inner bevel gears that the new differential has. However this compatibility may unintentionally be lost as my modded version is developed.

Today I am building the original set with real bricks then seeing how I can add my mods to it.

right, that's what i thought - the new differentials are in the unofficial part database for LDCad actually ;)

can you share the full LDCAD file of the original model or is it a no-go ?

Edit: is there any specific reason you are using the small turntable to connect the drivetrain frames ?

Sure,here you go.

I will take a look in LDCAD and use the real differential parts :)

Sorry @M_longer i think we kinda hijacked your thread here :) i wanted to ask - how long is the list of additional parts for your modification (if you have calculated it already) ?

No, I am finalising instructions for the CLAAS Scorpion telehandler, 42108 mod is next on the list.

Great, i cant wait, i mostly wonder how you worked the steering around the outriggers in the front - i got the back mostly figured out and parts are on their way but i am baffled how to handle the front part (meaning, the steering gears are in the way)

I am really curious if you have figured out how the outriggers itself work :D

Yeah I literally fitted the 7L gear racks just now and forgot that the darn mini turntables would get in the way of the steering axle. The steering axle cant go up any further either so im in a very deep hole now and am trying to think of a fix.

The mini turntables allow for the pendular suspention whilst supporting the axles. I just don't believe LEGO sometimes!:wall:

I am lazy and ordered the outriggers from 42043 and i hope i will be able to use them (at least the back should work), the retracting mechanism i found something like this but it's not my priority:

If it doesnt work then i wait for your design ;)

They will be much more wider than the carrier. I have made more compact version.

yes, 2 studs on each side, i know but my 4-year old needs at least the back outriggers because he plays with it constantly :D i can always rebuild it with your version later on ;)
