How to Shim RC Car Gear Diff Differential [Beginner Tutorial with Ryan Lutz of LutzRC] 

This video is excellent. You really understand the fundamentals of teaching.

Very detailed & well explained. Helps show just what it takes to compete at a higher level. Thanks & keep the great videos coming.

Well this would explain as to why both bearing on the front and rear diff cases were blown, I pressed the cup to bearing as hard as I could and tighten the grub screw. Lesson learned, thank you again for your great build tips!

Thank you !!! Just bough a ZD racing 1/8 and though it was extrem bad quality diff until I saw your video, now with shims it works perfect and very happy !

Thanks mate, I've just blown the rear diff on a brand new DHK Hunter after only the 3rd pack.! I've opened it up & not only was there no grease the ring gear was so slack it was only engaging about a quarter of the way in. I wasn't sure about the amount of lash in the teeth & this vid really helped me.! Thank you, subbed & liked & best wishes from Scotland.! 😜 👍

Very detailed yet simple video, well done! Arrma 6s basher and casual AE racer.... there are many videos out there for the bashing community but not as clean as this one. Thank you.

thank you so much ryan for showing us the correct shimming ...salute ! enjoy racing

Excellent video!

From a new savage owner absolutely amazing 😎

The set screw is machined with dimple and then hardened. The dimple/cup bites into the flat of the shaft. No need to modify it. And yes use a VERY small amount of Loctite on it, but the cup should do the work and Loctite is not needed.

Yes thank you for this Bigtime 👊😀

wow.. very usefull info... thanks

Great video!!!

Top tips 👍👍👍👍👍👍

That Agama is nice stuff

nice work

Thanks for this👍

👍🏼

Great video! i learned alot but i noticed one thing. At 3:00 you talked about wanting the bearing holder loose on the bearing... that is not correct. for everything to function correctly the bearing holder should grasp the outer bearing race securely... otherwise the holder will be rubbing against a spinning bearing race and wearing away fast but even more important, it will cause excess friction and heat in the bearing...

Hi Ryan, is there reason why you dont shim from the pinion gear side? I was always wonder that.

so that is why my RC diff kept stripping! thanks

hi there, what do u call those 2 circular aluminum on both sides where you put the shims? where can i get it? will it woork for arrma kraton 6s? thanks so much for the informative videos....

One shim just caused my bearing seal to get shreaded to pieces and killed my brand new diff i keep eating diffs no matter what i do im speachless at this point i tried something new and it was looking like it was working before my bearing got nuked

what about internal gears? do those need to be shimmer manually aswell?

Sudden accleration backwards causes clicking in the gears please help im a noob ive opened both diffs no stripping that i can see

So the gear mesh doesn't matter. You just randomly shim till the slops out huh...
