Technic 42042 Modification

Hey Everyone, Here is a very quick, easy, but very effective modification of Technic set 42042. Many on Lego forums have clamored about the lack of lifting power of 42042. Again, they complain of the lack of power in Lego PFs. I am here once again to debunk that complaint, and demonstrate that with simple steps the lifting power of 42042 can be unleashed.
About this creation


My modifications are very simple. I have increased the boom by a few stages - too easy. This does not help with lifting power, but I think it better resembles real cranes of this size. The secret to unleashing the power of 42042 has nothing to do with increasing its power. Just utilizing all of it. In the superstructure gear box you will find two clutch gears. When trying to lift heavy objects with the original version, and you hear clicking and see an inability to lift much, it is not the motor that is stalling, simply the clutch gears clutching....lol, skipping. Simply remove these, replace with regular 24t gears (it does not matter the old, aka weaker gear, or the newer one, I used both in my demonstration and both worked fine. No cracking, etc)...

Here is a video how to do it:



If this went too fast, instead of pausing the video all the time here are the pics. As you can see in the vid, with these changes I lifted over 800 grams no problem.














Have fun modd'en!

This is very helpful, considering I once tried to make a car with a clutch gear that couldn't move because the battery pack weighed too much. Thanks!

Great set, very helpful mod. Those clutch gears just slip too easily to be any use really.

Yea....easy fix. Like I mentioned, took me like ten minutes. I like the 42042, but Budapest and SBricks sound pretty nifty too. Either way, stay firm my friend, stay firm lol.... http://www.moc-pages.com/moc.php/406630
Quoting Jeremy McCreary Very effective mod, NFP, and you didn't even have to tear the entire house apart to pull it off! Kinda wish I'd sprung for a 42042 now, but most of my LEGO budget has been going to Budapest for more SBricks lately.

Quoting Stephan Niehoff Wow, what a big mashine.
Thanks Stephan. Fun to build, even more fun to play with.

Good question. You should probably go with the beveled-tooth gears. 12t or 20t....dependinding on how much room you have. Beveled gears give you a better connection for the gear meshing you are discussing. Have fun!
Quoting Johan van der Pluijm Well done! Maybe you can help me: what gears are the best to make a 1:1 gear ratio while propelling a North-South axle with a East-West axle?
