Pro Tip with Spencer Rivkin - How I Break in my Ball Diff

[@AugustusMcMillan]

im a fan of yours because i just watched a KZbin where the channel has less than 100 subscribers. BUT you spent a good amount of time giving him a LOT of good tips on his setup. that was awesome of you!!!

[@wbhandy]

This was so helpful for setting up my ball diff for the first time coming from a gear diff. Especially all the detail about how tight to make it. Thanks!

[@spencerrivkinracing]

Awesome! Glad to help out

[@stevenstrong8235]

Could you tell us where to get the L wrench ?

[@plukensteinpaint]

I’m about to build my first buggy. The B6.2d and I’m really happy I have found your channel. It’s been super helpful for me! thank you for sharing

[@baggszilla]

Hell yeah another world champion video 💪

[@mariowoodsN5]

Hey Spencer just got my new B74.1D, just started the build👍🏆‼️🇺🇸

[@eppidemic2212]

You should make a video on your current rc10 setup.

[@jordanritchie2198]

Nice vid and glad u show us the inside or ur car. I am new to racing and have been socking up ur videos. Going tomorrow to practice for first time. Wish me luck😜

[@richbc517]

Salute and more power. I wish you can show us too on how to properly adjust the top end and bottom end of the nitro engine ..usually top end is a bit easier but the bottom end is the one im stragling on how to adjust properly and how the car react ...good job sir..

[@samgee9418]

Great video Spencer. Where do you get that L wrench?

[@robertmoore119]

Breaking in the diff will be beneficial. When I used to race, (B3), I never did that process, I just set the diff as per the manual. I did keep track of the way the diff felt, I would do a rebuild as soon as I started getting any barking. If it was smooth then I was happy, but I know more now than I knew back then. I'm looking forward to racing again. The cars have developed alot since the RC10 B3. The B44 had just been released about the time I was about to stop, but I wanted a B44. I raced stock 27 turn and mod here and there. I also did some inroad racing with a TC4. I plan on getting a 4 wheel for 17.5 class. But the 6.2 also looks really good. It would be even more fun If I had one of each, then I could race spec and mod. Good luck racing!

Hi Spencer, what's the tool you are using for tightening the diff?

[@spencerrivkinracing]

It’s an old L 2mm tip I found a long time ago. I think there might be a few companies out there that make them

[@sshevnock]

It's a fancy allen wrench

[@19TMH77]

​@@spencerrivkinracing Excellent tip and video, thank you!

[@mikeblythe4398]

Way to build your brand, Spencer. And thanks for the help trying to get Pauls RTR going a couple weekeds ago.

[@trevorfurlotte]

Hey Spencer. How far out is the diff screw at the start?

[@jstump1972]

Is that the losi diff wrench? I cant find a ae one anywhere

[@10krms8]

I been whanting to get into indoor racing not sure which car to get i really like the one u got where can i get one for a good price along with the electronics thanks

[@lionellawson2808]

Where did you get your diff tool

[@bry0ung]

Thanks, Spencer, this helps.

[@cagrowin1962]

do you use sanded rings? or grind your own?

[@robertherzog9294]

Hey Spencer, it was good meeting you and your dad at the Reedy race at OCRC, I said hi to you at your pit space and then I talked to your dad afterwards for a little while. I was a top oval racer for ten years in the 80's and 90's, but this off-road driving is fun now that I'm getting the hang of it and getting rid of the dust and cob webs out from not driving for so long. I've been breaking my diff in with hand drill lately, just wondered if you ever tried it that way or not and if you think there's any significant advantage to doing it that way or doing it in the car. I'm not experienced enough to tell the difference except I don't tighten the diff all the way until I get in the car and spin the wheel while holding the spur gear (I think I read somewhere that was one of your techniques for checking diff tightness).

[@spencerrivkinracing]

It’s what nice meeting you too!

[@timpetrak4780]

Thank you!

[@Crewchief227]

Tell me about the haircut thing🙄 Anyways Spencer, I just got done building the rc8t3.1e. I have the rc8b3e so I'm pretty familiar with the platform. However I'm getting a clanging sound from the front center outdrive. Is it because the dogbone pins are new, or is the diff binding? Cause she feels free & smooth, gonna break down the diffs again today anyways to see how's she wearing in. Thanks for your insight snd videos. It's a good time to do all that wrenching we've been putting off😂👍

[@cwalton00]

If you are using direct drive what's the best way to check if the diff is tight enough?

[@rbc626]

Hi, about how much forward trim do you put in your Futaba when you are breaking in your diff?

[@andrewsumner5388]

Just got a new SC6.2 is the break in gonna be the same?...

[@jerryboics9550]

Just got my 1st buggy and I'd never seen a slipper or a ball diff. The b6.2 manual has very limited information on it too and also doesn't mention how crucial it is to set up 1st without doing damage. I got it set up correctly from that info but I barked it a lot more than once getting it there....

[@tydavis6150]

At 8:34, how fast do you set your sub trim on the radio.

[@trevorfurlotte]

Hey Spencer. Thanks for this video. Excellent for a newbie. Where can I buy that 2.0 wrench?

[@spencerrivkinracing]

I think it’s another RC car brand I got a long time ago. It might be a TLR part

[@LyroLife]

Why not disconnect the pion from the spur gear for best diff ball resistence testing

[@laynelommen9460]

Why do you grease the back side of the big rings? I didn't think they spin. I figure grease would just build more heat.? Let me know at your convenience. Thx for the video.

[@jeffbryner5355]

I wish i had down time!! Im an essential employee lol

[@christianthausing7982]

Thanx for your helpful videos. Great stuff. I have an 6.1d and have troubles with my slipper clutch. My front wheels don’t come off an inch and it slips all the time. But the slipper pads and the clutch are new. Could it be the ball diff? Any advice? Thank you in advance

[@spencerrivkinracing]

Thanks for watching. shoot me a message on FB of a video and we can figure it out from there.

[@MrZimeir]

oh snap, better break in my diff

[@aaronsalais3477]

Spencer I got a reedy 510r esc and a 6.5t hobbywing wing motor when I solder the esc wires to the motor posts the wires and solder aren't taking or sticking to the motor posts. Any and all help is appreciated

[@johnford2244]

What front wing/mount are you running?

[@spencerrivkinracing]

It’s the Jconcepts wing and mount

[@jesus686]

why my car never pulls the wheels when I try that

[@mgers75]

I don't think you need to worry about any diff lube coming out during break In by turning up the rpm too too high. As soon as you do a 25 foot triple and have to keep it pegged in air its all going to sling out anyways the first lap

[@spencerrivkinracing]

It’s not that I’m worried about it coming out. I’m making sure the grease isn’t over heated on the initial breaking. When greases gets hot they water down and break up. If you can control that for the break in you’ll have a good well greased diff for racing :) Thanks

[@lancesmith6724]

I got a question i bought the reflex 14B as a RTR i ran it on the road a few times at my house the front tires started getting slick so i stopped an took it to a dirt track at my local hobby shop 2 times an the mane diff were the spar gear is like melted were the baring sets on the chasse do you thank that could be my doing or a bad assembly caused it it started sounding like the motor was loose an was grinding my spar gear up to i took it apart an the spar gears fine!

[@spencerrivkinracing]

Hi there, I’m actually not familiar with the 14B. Was there an issue when you we’re running on the street. I would contact Team Associated and see what they can do for you.

[@lancesmith6724]

@@spencerrivkinracing No it was smooth an then it started grinding sounding not so smooth so what i saw was were the center drive shaft goes into the main deff by the spur the center plactick race melted!

[@aaronsalais3477]

Spencer I see drivers practicing with a "Center Diff". What is a center Diff?.

[@seanmmonaghan]

B6.2 ....?

[@masonherrick04]

I noticed on your B3.1e setups from the nationals and silver state that you listed your esc as the XR8 SCT version. Is this correct, and if so, why did you choose this over the XR8 Plus?

[@spencerrivkinracing]

I like the xr8 plus

[@masonherrick04]

Spencer Rivkin You like the plus more than the SCT?

[@jstump1972]

SR racing needs to sell broken in diffs :)

[@sameuljones5496]

Never needed to break in my diffs. I've always thrashed them out of the box currently had over 70 lipo charged batteries thru my diffs and no issues at all

[@gradertfamilymakes]

@@sameuljones5496 too bad you're too good for the geek fests. I'm sure you'd kill it and they'd all loose their jobs and you'll be the king of RC. Nah, your just a stale old dude who goes on pro RC driver's KZbin channels to talk crap about how much better you are and how proper maintenance and procedures are over rated. Gotcha.
