I was thinking about installing the 3rd bearing block for the tail counter gear on my Evo. I know it's not absolutely necessary to have this item, that's why I said I was "thinking" about it. I found the Hirobo part # for the bearing holder minus the bearing (0402-523) but I'm not sure about the bearing part #. I did a search and found two different numbers mentioned (2500-068 and 2500-079) The 068 bearing is 5x13x4, I don't know about the 079. I don't have the Evo manual in front of me at the moment, so I don't have the part # or the diameter of the counter gear shaft to compare with the bearing size.

If any one has installed the 3rd bearing block or if someone knows which bearing to use can you please let me know.

Thanks in advance.....

it dose nothing but make the tail harder to take off when you want to i think the bearing is like 8$ and 6$ for the plastic part spend the money on fuel

#2500-079 is 6x13x5

So you want a 2500-068.

Hi G Dog,

If you crash and change your counter gear shaft then disect it and you will have 2. I've crashed a couple of times so have a few spare. Send me a pm if you want one and I'll post you off one with the screws etc for a smaller fee than buying it.



btw. people will argue but they are worth it with the tension you are running on that belt.
