had the comm cut..?

[muddeprived]

I ordered some 35t integies from HH and i chose the option to have the comm cut. Visibly, i cannot see any changes on the comm, maybe i'm looking at the wrong place or something.

What exactly does cutting the comm do? Do i still have to break in the brushes? this is on my 14.4v 1:6 JK and it gets some pretty good speed. It's no slow crawler, but can be.

should i still break the motors in? water? I read that water is the thing of the past. That's what i used to do.

I would run it with the trim up half way for a couple minutes in the truck. If you use water, it will strip the brushes of their lube. So if you do use water, just remember to change the brushes for new ones after.

from the HH page

For extra smooth low speed control we can cut the comm on your motor before shipping. We have found the average Integy comm to be 0.08mm out of round or more.

it is not visible but the comm is round after cutting

Right basicly the surface of the commutator is cut precisely. Allows for better contact and smoother operation.

Yeah i read that, i figured i could see the cutting on the comm, like it's been run (shiny) but seems like it's still the same as it was new, copper color.

Isn't breaking in the motor for seating the brushes to the comm? If i run it in water, and then replace the brushes, i'd have to break it in again to seat the new brushes, right? or am i missing something here?


Next time i'm gonna invest into some seriously good motors. The integies are alright and get the job done but they wear out faster than i like. I'm on my 3rd set in about a year so far. I run it hard though, at full speed, jumping and all that stuff. Mud and water too.
