201 Idler Gear....

did the pin come out of the top shaft?or did the gear just wear out?

No way is that wear, 2 teeth gone, rest look fine, I reckon the pin must have come out!?

would really like to no the reasoning behind a two piece topshaft.is it worth the problems people are having with pins coming out(refering to the couger sv aswell)
|
#5

|
||||
No no the pin is ok! It's a real problem if it's the same of SV
|

that is an escaping pin from the top shaft, to of caused that problem.....
If someone is building a kit as a shelfer, could i borrow the layshaft and top gear to have a one-piece one?

Surely if it was the pin falling out it would affect more than two teeth?

depends on how it fell, it it bounces and then lodged, no... but without seeing the rest of the gears, it is impossible to tell fully, but would find it hard to believe out of all the teeth, two would shear off from a faulty mould...
See what happens.

Thats a sad sight to see.
I am the one behind the Dyna Storm evo/lighting project on tamiyaclub. When the prototype company was redesigning the slipper shaft on that they wanted to do the same as the 201 and, as I am reading above, the SV - use pin(s) to locate the gear. This was because it was too expensive to machine the shaft like the dyna storm orginal - with the little ribs all around, locating the metal gear insert. Could be Tamiya has done the same thing here (ie. cost reasons). Pity. |

If it is the pin then it can be sorted, some jb weld or even a bit of heatshrink may do it!?

AE Black Grease should be used or a grease that is highly resistant to wear. AE black grease should prevent that from happening... I think the grease got hot too fast and the gear melted... It's also aparent we need to know what motor he ran to get it to do that. If it's not the pin coming out of the counter gear then it's that cheap grease... I have some automotive gear grease that never wears out...that would also work. Get it at an autoparts store.

Its not wear its mechanical damage Only two teeth are affected, the other are fine. If it was wear then all the teeth would show damage too. Black grease ( Molybdenum diasulphide i think is what it is ) - i only use it on thrust race assemblies. Never heard of it being used for gears. |

One of the guys killed an idler gear after one nite. He said it was from driving ruff and doing donuts.. I think its either a defect in the material or this though of the pin dropping out and doing damage...
I wonder if under no load full throttle(aka doing donuts or WOT in the air) if this could cause the pin to move? Ill take a look at mine as i have to rebuild my diff after 3 races now(relube mainly) |

just building my 201 at the moment.have examined the idler gear and noticed at various different points the material looks weakend(its whiter than the rest of the gear material).have examined the spare idlers i have aswell and they are the same.it is mostly along the base of the tooth or at the outer edge.could this be a sign of a problem with the material(it seems alot harder than the material used by ae) thats causing the problems
