Default Tamiya TA05.

Hi there, i'v just got in from having a bash with my brother with my Tamiya TA05, and whilst it was running, the centre pulley section (possibly) starting to make a clunking noise, as if the motor was skipping teeth on the pulley.

Further investigation showed no signs of missing teeth on the pulley, but still the centre pulley was making a lot of noise.

Just wondered if anyone has had the same problems, and if you have, what was it/how did you fix it.

Thanks guys!

Probably grit in the pinion/spur gears.
I had this happen alot, cost me $$$ replacing gears all the time.
Damaged pullies dont seem to be noisey.

The grit is very hard to see, it probably stuck inbetween 2 teeth on the spur, pushed right into the gear.
if you turn the gears slowly you may find where it is, otherwise scrape out each space between each tooth with a knife point.
Have a look for slight damage on the pinion.

TA05's dont seem to like dirty tracks (both of mine have issues with sucking grit into gears)

I've never had a problem with my TA05, and my street is covered in grit and small stones. I think the manual tells you to grease the pinion and spur (can't remember.) Anyway, most people who have problems with dirt in the gears have greased them. If not, then you're unlucky

I think its the car. Both my 2 TA05's have been retired because of this.Both my Xray's (T1 & T2) have absolutely no issues like this. When I showed a couple of guys at the track just how much grit was collected in the car, they were dumbfounded.
Both cars have different bodies so its not that. Even tried blocking up all the holes on the bottom and made a perspex upper deck for one to try & keep the wee stones out. No grease on the gears either.
I know some other TA05's have this problem from posts on forums.
Sucking up a cigarette butt was the last straw (along with another set of
gears ruined after 5 minutes )

I'm interested to see what Mousey's problem turns out to be..

Check the screws which hold the spur gear to the spur gear holder, the may have worked loose.

Been running a TA05R for 2 years on dusty street condition.
What I do after some few run is grab the car from its chassis
and flip it and shake it to release the accumulated rubbish.
The center pulley gets mushy after 4-5 sessions, you'll notice
the two center pulleys strayed away from the spur gear holder
thus causing binding, just push it back. I use 48pitch gears so
whenever I hear some strange gear noises, I just check the
gears and remove the stuck small stone. Sometimes the belt
will catch some twigs and derails itself from the center pulley,
thankfully the tub chassis it forgiving and slightly bends to
give you enough room to remove the debris.

What would be the damage threshold? At what point do you guys decide the gears are too damaged to keep going.

My current set is fairly new, but has slight marks on it here and there, right now it's just making more noise than anything serious, but where do you draw the line?
