question i got one of the older hsp sonic rc cars now got her running couldn't finish tuning it seems it don't go anywhere the gears seems the pin poped out and not suer what i can use any help it's a moderate gear set part number 02076

ehroof

we carry the whole setup if you need it, what part do you need, that little needle pin that holds the gear on? use a body clip

harley75

the pin is in but seems it don't engage i guess i get the whole thing #02076

ehroof

just drop me a pm or an email bro if you want the trans but before your do, does the clutch bell spin and the spur gears? maybe your drive cups are loose?

harley75

yes they spin

ehroof

maybe your drive cups are loose, tighten the grub screw in them first befor you buy a new transmission

harley75

everything is tight

ehroof

if everything is tight and the spur and clutchbell are spinning then i dont really know what to say. are the front and rear dog bones spinning, the ones from the trans to the front and rear diffs?

harley75

it is something with the gears for some reason the trans isn't working the gears spin but it don't trun the dog bones

ehroof

did you take it apart at any time? Maybe you put the one way bearing in the wrong way?

harley75

no didn't take apart the only thing i see is that the big gear in front just spins and the little gear behind won't engage i don't know what else to check

ehroof

sounds like either the one way is shot, the pin or the gear is shot, the 2 gears should turn no matter what, my opinion and what i do is put a single speed trans and change the clutch bell. I like the single speeds on offroads, especially the other style rc's.

harley75

the pin is in the smaller gear but it don't connect to the big gear ans there is no little hole for the pin to go through the big gear

ehroof

there should be a one way bearing inside the big gear, maybe that is backwards but you said you didnt take it apart.

harley75

i didn't i looked between them there is some play between the gears.Car work fine when i was try to get her tuned then it just stoped moving.So i just order a new trans and go from there.I'll pop the order in tomorrow

ehroof

ok bro but email me before you order, i will see if i can figure something out for you first.

harley75

ok
