Repair of radio-controlled tank

Hello dear Yapovtsy!
This is my first post so for curvature please do not kick.
12 photos will be described at the end I will inform you.

Earlier in the vast YAP was a post about entertaining grushke- tank battle in which colorfully described all the delights of this wonderful toy. However, sooner or later, any thing breaks down and it is necessary to do something. So it was with a tank battle.
One of the tanks has become a leading roller scroll that was the reason for the repair.





The reason for treatment was a traffic violation tank. On examination, it was found that scrolls leading rink.



Remove and inspect the tracks



During external examination the reasons for failure was not found, so the tank is disassembled and look further.



The main components of mechanics treated with grease, so do not see all the gears of the drive. We'll have to analyze further. We remove the engine.



Mdaa ... grease a lot, but it is not evenly distributed.
In order to identify the causes of damage to remove the engine nacelles and remove all grease.
As a result, it turns out that the leading roller rotates due to the backlash of the shaft. (Unfortunately, due to the grease-stained hands to shoot the moment to hold, could not.)



Since the replacement of buildings - is the same as the cost to spend the floor of the tank, it was decided to make mount- limiter. This mount will allow a shaft in one position. Fixing make of stiff wire.



In order to ensure secure mounting and durability design, customized size to the diameter of the shaft.
