Arrma How-to: 3S metal Diff Install. Why did my metal diff fail? This video will show you how to replace gears, bearings, grease and differential fluid. I will demonstrate with great detail how to remove the gears, bearings and fluids in a 3S or 4S Arrma RC car differential gearbox. I will transfer all gears from a stripped main gear case to a brand new Arrma metal replacement. Then I will show you how I grease the input gear and the main gear. You will also see a full disassembly from removing the motor module and back to it's fully re-assembled state. This task can seem overwhelming at first but I will guide you through the process and am sure you will learn plenty today.

Still my favourite channel for the Arrma Granite BLX Tips and Tricks. This man has helped me out plenty with my Granite BLX, and most likely why I bought one to begin with 🤪 Great video brother 👊🍁✌️

Metal diff and plastic diffs are the same, they both strip at the same rate, plastic diffs are composite and not just “plastic” They are filled in with hardeners or reinforced with hard materials such as carbon fiber and other composite materials. So don’t worry, your arrma can last 1 year with those plastic diffs if you take care of them, to reduce the shearing risk loosen the slipper clutch screw, that will make the car handle much better and tolerate breakage during high stress. Also fix the gear mesh contact and just move the motor just a little bit, try to get that pinion - spur gear contact perfect, don’t make it too tight and don’t make it too loose, All you need is 1mm of play in there and that’s it. And by the way tighten that slipper clutch to the point where it is snug, spin the slipper if you feel it too tight, loosen up the screw little by little until you get the perfect feel to it. And don’t forget to put some thick and sticky grease to the diffs and the slipper.

@timmurrayy 8 месяцев назад

Just rebuilt both my Granite 3S diffs. Lost the front completely (input gear totally worn out) and checked the rear which I’ve done before and was surprised to see the teeth worn to sharp points! Replaced that too. Redid all the bearings. However both diffs are tight in the plastic yolks - I’ve read they flex open under load and would have less binding as a result so shimming yolks, removing shims to make them spin free by hand may allow the mesh to open too much under load… not sure what side to take on this one. Metal yolks might be the move but it’s hard sinking more and more cash into a 3S truck.

@phillybrc 8 месяцев назад

I hear ya on the spending money part. It s too damn much! Many like the metal yokes, I have yet to buy a set. I put a to y washer between the yokes to give a touch of play. Trial and error and feel it out

@timmurrayy 8 месяцев назад

I was considering the full metal diff replacement plus the M2C motor plate & support but it’s over half the cost of the truck in those alone. And I have 2 trucks to do… lol. Might move myself to a 4S v2 outcast and keep my repaired 3S for my youngest who’ll be ready to use it in a year or so. I think the new 4S line driveline should be strong enough for me and the shimmed granites should be ok for the kids on 50%. They’re just so much fun I don’t want to walk away at this point. Just got to make intelligent upgrade & maintenance decisions. Videos like yours really help the dads at home juggling multiple trucks with minimal time so thank you very much for sharing the knowledge!!

@phillybrc 8 месяцев назад

@@timmurrayy Thanks for the compliment tim. I appreciate that. The 4s v2 versions seem alot more durable and have more of those durable parts. I couldn t agree more on the spending part of this hobby. The parts cost as much as real car parts sometimes. I think the red motor plate is the weakest part of the truck. I would like buy the m2c motor mount but the rc budget is hurtin right now lol. (I have 3-3sarrmas). Kids (and myself also) love the Granite because it s a flipping machine! My son breaks so much stuff lol.

Hey great video thank you very much for the details! How is this holding up? Did you have to move any shims? About to rebuild both gifts right now and didn't want to make any mistakes. Thank you again for your quality content!

Hey! You re welcome! Ya, still running well! Shims kinda vary car-to-car u fortunately. My last 3s Arrma video has my Granite with metal diffs in it. Runs great. Thx for watching

@arq.andresfelipemoralesvar9593 8 месяцев назад

Hey my friend! Your videos are so awesome and i really enjoy watching them, as I’ve been using my ARRMA Granite for around 17 days (32 battery packs already lol) i always put your videos to learn tips and how to disassemble and reassemble my Rc car. Huge thanks because the tutorials are flawless. Finally i stripped my stock rear input gear and few teeth on the stock rear diff (i heard a clicking on the car while i was using my ProLine Trencher Tires, not sure if that was the cause of the damage, but anyway) I wanted to ask if for ARA210007 part should i also shim some parts and add washer to the Yokes? I’m sorry if this question is dumb, I’m kinda new in this and there’s no hobby shop where i live. Again thank you for all your videos, you have no idea how much they have helped me to understand not only about mechanics but also about driving skills and general RC world. Blessings my friend, thanks for your time

@phillybrc 7 месяцев назад

Ya, of course. No stupid wuestions here. As for shimming, if i understand the question, it depends how the diff feels when it s put together. The shim usually comes on the crown gear(big gear) side. That shims physically “pushes” the crown to mesh with input gear tighter. If it s too tight and feels notchy, remove and put back together, if still notchy, you may want to move the shim to the oppesite side. Since these parts are plastic, application could vary. Make sense? Lol

@arq.andresfelipemoralesvar9593 7 месяцев назад

@@phillybrc much appreciated sir! Blessings for always helping rc community. I decided to purchase the Arrma metal diffs. I’ll be very careful about the tightness of those parts. Also I decided to decrease my ESC punch 1 point (from 3 to 2).

@All-rc804 4 месяца назад

I just got the cnc metal diff gears and I’m really disappointed as the mesh is far too tight. Will adding washers between the yolk’s make the input gear wobble about?

@phillybrc 4 месяца назад

It s hard to say, not likely. You dont want all that resistance either. If it s that tight, take apart and build again. Possibly you missed something. 🤷‍♂️

@All-rc804 4 месяца назад

@@phillybrc yeah I’ve taken it apart probably 4 times😩 and still too tight. I’m using all new parts as well. New diff case and gears. I’ve added washers and seems a lot better but there seems to be play in the input gear.
