Very helpful... knowing the shim sizes to get saved me a bunch of experimenting

[@ELValenin]

I always break the pins you upgraded here in my rear diff - will try this!! Thank you

[@doozie4256]

I picked up a Senton recently (awesome truck) and have bashed it about 10 times now. Just today I went ahead and pulled out the center diff and replaced its fluid with (stock weight 10k) diff silicone since I had a pretty poor pinion/spur mesh. How often should I replace the front/center/rear diff oils? Should I be replacing the front/rear diff oil soon or am I already past due? Replacing the center silicone was relatively easy for a noob and this vid definitely makes it look easy for the front too, which is great. Thanks for the vids I really appreciate the info! :D

[@TpPartsRcXtreme]

thank you mate. you can easy change the front and rear now. hmmm i have no specific scheme i change after...but say every 30-40? i changed mine around 20 i think. its allways nice to have fresh oil in the diffs

[@EastTactics]

Is going to thinner in the rear differential the proper tactic To minimize breakage? I see people doing 80 K in the rear 200-500 K in the center and 80 K in the front. But I’ve noticed that you run a much thinner diff fluid in the rear. Does the thinner the fluid in the rear help prevent damage? I don’t know why but for whatever reason I always thought that the thicker the diff fluid the more protection you’re giving to to prevent/minimize breakages. But I’m starting to think I’m wrong. Can you clarify

[@Juoperi]

A very nice and clean how-to-vid! Good job!

[@TpPartsRcXtreme]

thank you chief ☺

[@spencerrobbins2871]

Thomas thats a sick how to video you have made😆keep up the awesome work and looking forward to more vids.....peace

[@TpPartsRcXtreme]

thx Spencer, more will come 😂

[@99SiR]

Tp-Parts Rc-Xtreme, I appreciate your quality videos! This looks like the center diff here, do you still use 2 of the 3.5x12x0.15 washers on 1 side of the cross shaft pin? You don't show an extra washer in this video but you do use an extra washer in your front/rear diff video. Just curious if the center diff doesn't need an extra washer on 1 side or if you don't show it since this is an older video compared to the front/rear diff shim video?

[@TpPartsRcXtreme]

RD eazy all 3 diffs are shimed under the big sun gear in each diff. total 6 shims for one car. tje smaller planetary gears will use the incl shims ( no xtra added ). i just ised the centre diff in this vid for i hade it out of ma car

[@jeffreym6816]

Darn it lol. I just shimmed to center diffs with the 2 - 1, 2 - 1. Also I can see you didnt put shim on shaft cup on the big sun gear. Thanks for the videos tp, ive watched your other diff video a billion times lol

[@MrKalani938]

So look for 2.25mm drill bits? Where do you get yours from?

[@megatidraizwanmohamednazaz6377]

Tp-Part Rc-Xtreme, what is opinion diff oil setup for arrma nero big rock? is it same with Kraton 7k rear 100k mid and 60k front?

[@TpPartsRcXtreme]

Since the Nero series do not have sealed diffs it will be hatd. Need to use grease or they will leak ( due to the lock mechanism ). I havr sealed the diffs in my first Nero, and it seems to work good so far

[@megatidraizwanmohamednazaz6377]

oh if that so, do you have video or tutorial on how do you seal the diffs? do you record it? or upload in youtube.. if not can u show me the way u seal the diff.. can u whatsapp me the step [phone]

[@megatidraizwanmohamednazaz6377]

so, if i use diff oil like u use on kraton diff, it will leak? if not i wanna buy diif oil.. what kind of grease do u use? brand or type? sorry, i really want to know..i just buy arrma nero big rock 2 days ago, and start worry about the diff. i still newbie in this rc hobby..so, there are so many thing that i still dont know

[@TpPartsRcXtreme]

Megat Idra Izwan Mohamed Nazazi to be hounest my friend, i jist used marine greese. But if yiu only had it for a few days dont worry. Just run it and have fun. I opened up my diffs after a few month

[@megatidraizwanmohamednazaz6377]

ok bro..i just bought 30k for front n rear and 100k for mid because my friend use big rock..he said no leak.. ok2..i wil buy marine grease too as u used

[@uglymusa1759]

Do I need to use the drill bit for both pins?

[@TpPartsRcXtreme]

yes. all 3 diffs. meaning 6 drill-pins.

[@TpPartsRcXtreme]

+Tp-Parts Rc-Xtreme 2 in each diff

[@uglymusa1759]

+Tp-Parts Rc-Xtreme thank u sir

[@fumanfpv6764]

what is your diff oil setup?

[@TpPartsRcXtreme]

Kraton 7k rear 100k mid and 60k front

[@brandonhale1280]

hey guys what does shimming a diff actually do? sorry I don't know thanks

[@TpPartsRcXtreme]

the main reason is, to get the right mesh between the gears

[@MrDavide1976]

hi! can you translate the "k" in "wt" or "cst" ?? thanks in advance.......

[@TpPartsRcXtreme]

MrDavide1976 hi, SCT is more of a standard today ,WT from US. K stands for 1000. so 5k meaning 5000

[@MrDavide1976]

ok thanks, you made it just clear.

[@Raggesvenne]

Vart får man tag på 2,2mm borrar?

[@TpPartsRcXtreme]

ja köpte mina på Ahlsell ( vvs grossist )

[@Raggesvenne]

+Tp-Parts Rc-Xtreme Okej tack!

[@TpPartsRcXtreme]

+Rasmus Svenningsson eller välsorterade jörnaffärer, elfa.se kanske

[@Raggesvenne]

+Tp-Parts Rc-Xtreme Hur många behöver man då? Kan du länka till dom?

[@TpPartsRcXtreme]

+Rasmus Svenningsson ja har ingen direkt länk tyvärr. men man får ut 1 diff per borr. sp 3 borrar. 😊

[@PatisserieRoyale]

i was wondering why would you downgrade from 2.25mm pin to 2.20mm pin?

[@TpPartsRcXtreme]

the 2.30 fits perfect in the outdrive, but the sungear wont go over the pin...the 2.25 was not in stock so i took the 2.20 drill..and it have the same fitment in the outdrive. works like a charm, over 30 , 6s packs hardcore bash and it looking like NIB ☺

[@PatisserieRoyale]

Ahh Ok cool! Thanks for the tip!

[@TpPartsRcXtreme]

+Azmi np mate ☺

[@TpPartsRcXtreme]

7k rear 100k middle 60k front

[@ELValenin]

@tbrazin It's a bashing setup, not a track setup. Bashers like thicker diff oil, especially in the center, as it makes the car wheelie and have loads of power. Also it makes the front tires balloon less, which can be a real problem on 6S LiPo
