Note: On Sale;
Regarding the disassembly, installation and use of the upgraded gear:
=====
Note for use: In order to give better performance, it needs to be run-in after installation. It is recommended to run-in at low speed for 5-10 minutes.
====
For better use, we suggest you buy a complete set of upgraded gears, including differentials, big Reduction Gear.
Because the upgraded gear is made of hardened iron,
the hardness is close to steel, and the hardness is harder than the original zinc powder alloy gear.
Therefore, if mixed use, it may cause a certain amount of wear on the original gear.
