"My front diff bolt keeps breaking and makes my car a 2wd car and it dosnt handle right"

To which bolt are you refering? The bolt inside the diff itself (the one that holds to two halves together)? I've broken about five of those from over-tightening. Are you putting the spring in the diff? - that could be it.

Rowdy Racer:

Hi,
are you running the steel diffs??? I have broke a few with them. a quick fix is to find a small washer that will fit into the longer diff half. then install the spring use plenty of black grease when you build the thrust bearing and build the diff the rest of the way. I found that I was bottoming out the "T" nut. thus breaking the 2-56 bolt. the washer will give you little more space until you bottom out he bolt on the nut. one thing you must do is to tighten the dif a little at a time when you feel a slight drag when you tighten you your diff.

one other question. how many times hve you snapped the head off or somewhat close to it??? this tells you you need to space the spring out a little.

Jay:

I got "FORCED"into working both Sundays. Mini's gonna be pissed as he will miss racing. (Mini is my son's nickname).
I'm hoping I can talk someone into taking him.........
so the chassis really don't need to be shipped out ASAP.

Stephen Baker:

Hi,

Welcome to the team.....(yeah I know it's a little late.sorry)

Joe B:

Thanks

I am running the steal diffs. Most of the time the head snaps or twists off. Do i need to add a small washer or replace the stock washer with a "smaller" washer?

Thanks

Default bolt breaking.

It's not a matter of the wall actually hitting that bolt, but the "shock" the transmission takes when say, the right tire hits the wall, briefly stops (when striking the wall) and the left wheel wants to keep spinning. thereby kinda shearing the bolt in half. I've been there. I've also broken several dog bones (where the bone meets the axle and that little !#@$! pin breakes through the holes in the bone. ) I have since switched to Irs BIG DAWG bones and havn't had trouble since. I had the IRS composite, but didn't have good luck whth them. Seems I didn't even have to "smash" into the wall, but sometimes just graze it. Since were on the topic of Diffs, I recently rebuilt my diffs using Niftech alum. outdrives and their inner diff assemly. I did not however use their chrome diff balls but ordered ceramic balls from Acer. Simply SMOOTH running diff now. However, after doing both front and rears, was a total of $120 or so. But I have the smoothest diff at our track. Now if I could just learn to drive....things would be great.

Hey Stephen, before you correct other people's spelling, why don't you check your own? lol. I'm pretty sure it's DISGUISING.

Rowdy Racer:

Hi,

if you are breaking the heads off the 1-56 bolt you should add a small washer under the spring. what is happening is the diff nut is bottoming out on the threads. by oplacing a small washer under the spring you are getting the same amount of compression on the spring but you are not bottoming the diff nut out.
this was a common problem with the B2's when they first came out (also the Losi LXT's) when we ran stadium with the B2's we would snap the heads off at least twice a night. (foam tires/carpet). try adding a thin small washer under the spring.

acyier is right about "JUST" brushing a board.... that's how we snapped ours off indoors.

Thanks

Hey, Racer Chick, I bet Stephen can spell PORT 'O' POTTY correctly without his fancy dictionary........ ......I guess that was truly an "inside" joke Hey Jason , since Stephen is on the BMI team now, how about mabe doing a special PORT 'O' RACER team edition kit for him........Im not sure what all you'd like to include........but Im thinking everything done up in a special order "shit brown" carbon fiber would be fitting.........
