Hey guys

been Havin problems with my spur gear. I have done the paper mesh and it was fine took it out and it fried the spur gear right away. So I did it again and it dis the same thing any ideas of what may be causing this?
 
Here's what I did with my Speed-NT. I pushed it tight, backing it off just a hair. Rotating the spur gear, there should be one tight spot due to imperfections in the molding process. Make sure your motor mounts are tight, and there's lock-tite on the screws. I blew out two spur gears before this, and not one since, with some pretty hard driving.
 
I know the paper trick is a great idea, but I hate it. Lol. What I usually do is kinda what alien said. I push the mesh tight together and while holding the spur with one finger, I wiggle it until I feel the spur kinda "bouncing" off the clutch bell. You can feel just a tiny bit of play between the 2 gears. I've only replaced one spur and I've had my Tmaxx over a year.:D
 
I've NEVER used the paper trick, all i do is get the spur to just barley, grab the clutch gear, like without any resistance. ill basically do what alien does, get it pushed up tight then back it off until it will spin freely when you spin the spur gear in the opposite direction of its normal rotation
 
Could the clutch bell have anything to do with it? Bought another one put it on tonight ran fine for about 20 min then opened it up and there went the spur. Could clutch bell have anything to do with it?
 
I don't think the cb would have an affect like that. I've found that the gear mesh makes all the difference. I do what everyone else was saying with making it tight, then backing it off a little until it's loose
 
Make sure your clutch bell bearings are in good shape. Besides that, it's all in the mesh. Tiny amount of play all the way around the gears. As stated, a slightly tight spot or 2 is common. I've never used the paper method either, though in theory it should get you real close. Especially with 32 pitch gears.
 
The gear your talking about is the clutch bell. It should spin nice and smooth. Any sign of grinding or play side to side is an indication of bad bearings. Make sure you use blue, removable locktite on the engine mounting hardware. Engine to mount and mount to chassis.
 
This will fix your issue

Ok, you had a bad spill. It went end for end about 10 times and you hit your motor. In doing so you have stripped the back 2 screw on your motor mount. Take a hex wrench and you will be able to turn the two screws on the back of the motor mount and they willnot tighten. Not the ones on the bottom of the truck but the ones on the motor. You will need a new motor mount $12.00 and another spur gear $7.50. Disreguard anyone who says anything bad about the paper set trick, it's flawless and is the ONLY way of setting the distnace of a spur gear properly.

Good luck I'm SURE this will fix your problem, I'VE BEEN THERE!!!!!
