i was driving my ruslter around the other day then it stopped pulling. i gave it throttle but the engine just speeded up like always but it's not pulling at all. can anyone tell me the problem ?[]

Could be one of several reasons for it not moving, The diff could be blown or not tight enough, If it has a slipper it could be too loose, The clutch could be worn out, The spur gear could be stripped... Best thing to do is to visually inspect everything carefully and go from there. You can also take it to your local hobby store (if there is one) and have them take a look at it, most hobby shops are willing to check things over for free and then give you an estimate for repairs and parts if needed.

well also i forgot to add, i dont know if its nomal because i never really listened to it but i took the motor off then when i pull the truck across the floor there is a clickin in the back end. but ithe sper gear looks good, it was tight when i was driving it. it never started doing this before but i hit a hill and the truck flipped ove about 4 times and landed upside down then when i turned it back over i made 1 pass then it stopped pulling.

Something might of been knocked out of place when the car flipped. My ATX did the same thing a month back. Just rolled, i put it on full throttle and she just SCREAMED back at me. Resulting in a Stripped spur gear. Check if the cogs/gears in your car still have teath in them. And If your clutchbell's teath are touching the spur gears ones. Have you got any pictures?

i havent but i can try to take some. what exactly do you need a picture of ? and i'll see if my camera willl work for me today

Just a picture of the car without the body shell on, and closeups of the area around the engine. Especially pictures of the gears also.

Cheers
Karl

EDIT:

How long have you had your car for? And do you use it often? Over use in the wrong type of enviroment can cause bearings to go ect. One reason my gears stripped so fast is because the engine wasnt aligned right and the bearings had gone in the clutch bell, causing it to rock and wear the gears down.

hope these will help.. sorry if they look like crap.. blame it on my camera []

oh, and i've only had the car for little under a month. i bought it off ebay, i dont run it everday but like everother day for only about 10 to 15 minutes.

take the tranny apart. be careful when you tak it aprt because there are little washers in there an you dont want to loose them because they are like spacers

i took it apart, all the gears in it looks New

Well you've got me puzzled. Clutchbell looks fine, Spur gear looks fine. Check that the spur gear is in contact with the clutch bell. I've just got 1 question.... Its a nitro car, how come theres a electric motor right next to the heat sink???

One reason I think it might of stopped is because the brake is jammed? The engines out of my car, and I was pushing the chassis around before and it wouldn't move. I was what you would call C O N F U S E D !! But then I realised someone had moved the throttle linkage so that the brake was on

Karl

its that ez-start motor that crank the engine over at the oush of a button, also nhill, take your diff apart, its the diff, cuz if the spur is fine, clutch bell is fine, all the gears in the tranny are fine, your diff out put yokes are fin, then its the diff,if it aint the diff then its striped driveshafts, they have like little igi things that connect the diff shaft to the wheel hub shaft you probably sripped it. if someone doesnt understand tell me i will post pics

if thats the big white gear in the transmission i already had that out and had the cover off of it. there is alot of little gears in it but they all look fine. the break isnt engaged or anything. when i gave the truck trottle it turned the spur gear but would not turn the wheels, the motor beside the heat sink is the Ez-start. it's for starting the truck.

does anyone here know where i can buy 20% traxxas top fuel by the gallon ?

To buy fuel by the gallion you need to find a hobby shop that carries it, the hazmat fees on one gallion shipped is to much.

On your truck, if the rear gears check out good, then the problem must be between the rear and the wheels. Do you have a manuel for your truck.

i had a pdf version that i downloaded from traxxas website.

it says Vehicle does not "go" a) Stripped Spur Gear, B) Stripped Differential Gear(s) , C) Slipper Clutch Set To Loose.

Have you tightened the slipper yet (does it make a difference)

I have the manuel but it sucks

i havent yet.. i gotta buy more fuel.

i think i found the reason why it won't move. i was cleaning my rims on my truck and one of my wheel hubs is stripped pretty bad. would that affect it ? i know theses are what connect the rear wheels to the axel.

That will do it, thats also the clicking sound ill bet.
At least you learned more about your truck, let us no if that fixes it ok.

How far are you from the nearest hobby shop.
If you have to order your fuel yourself get quarts no hazmat on them yet.

If your tires arent glued the rims could be spinnin in the tires
