The grubs have backed out due to the heat. Take them out and file them flat - I will look for the post on it. Then reinstall it using red locktight.

will do back in 5 and thanks so much.

Ok the thing behind the sput gear is good and the flat spot is intact, no play at all. The small gear infront of it doesn't move but the shaft in the middle spins when the motor runs and revs but the small gear wont.

You can also use blue locktight if you let it dry real good.
I cant find the post on the filing of the grubs.
Take the grub screws out and check the ends. Did they fold over or spin the ends off? The end used to have a bowl end that dug into the shaft. Mine stripped out 1st thing and I ended up just getting a file and filing the grubs flat by taking the grub all the way down to the 1st set of threads - Removing the cone on the end. Then reinserted them with red or blue locktight and letting it dry over night.

Good luck!

grubs are the set screw type things right? They are both completely loose did i do any damage to the truck?

I wouldn't think so. The grubs are softer then the shaft. Remove the grubs and do the above filing if they are damaged on the ends. If the shaft has some scuffs from the grubs spinning just file it smooth. You will see the dents the cones put into the shaft no worry there just file them enough to get the gear back on.

Yup. They make sure the gear won't spin around and ruin your day.

Check the grub screws in the wheel squares also. They are the squares that the rims fit over. Also make sure you check your rear tire nuts to make sure they dint back out and spin the square off the rim.

i would check all the drive line. axles, drive cups, diff gears, all grub screws on CB/Spur, Idler gear *gear that drives the diff) diff. crossbones on the drive shafts.


i hear they like to have loose grub screws, so thats one of the first things id look at.

sounds like a simple loose grub or such.

 

[marvo]

gonna go through it tonight, cant get loctite till tomorrow,store is closed. truck was a blast till it stopped running.

You will need to buy a small torch if you use red locktight for removal. Blue is the next best thing but not as good for the gears that are on the bell and get heated from the clutch.

I have this type of torch and it is the cats meow for our hobby.
