Emery cloth recommendation for CB

[MikeK1981]

I was running my truck pretty hard the other day, doing lots of wheelies and then all of a sudden it seemed like the clutch started slipping. It would still wheelie but not until like half way through first gear. It still worked pretty good but didn't have that initial "hit" like had for a while now. Before that it was wheelying instantly from a stop. The guy at the LHS told me to hit the bell and shoes with some emery cloth cause I may have some carbon build up there. I have not done this to date and I have about 4 gallons on the CB and almost a full gallon on the shoes but I just checked the shoes and they seem to be holding up well. Only minimal "mushrooming" on the edges of the aluminum. They are the dynamite max-life shoes btw. Do you guys use emery cloth or sandpaper on your CBs? How often? What grit would be good? Thanks in advance.

I no they recomend you to use a scotch brite pad on the cb before you install it.. Maybe you could try that on it ..

I sure do ususally is scotch brite though. I typically run around them every time there off, which isn't very often. This is especially needed when placing a brand new CB on to remove the oil's that are on it from factory and from machining, ect.

I think anything really works so long as your to to coarse, leaving huge gouges however I think the Bell is hard enough you will not gouge it enough no matter what.

 

[MikeK1981]

Yeah I was gonna use something super fine. If there is carbon build up on there seems like the scotch brite might not get it off as easily. And roughing it up on a very small level would give more friction for the shoes to grip. Anybody else ever try anything besides the scotch brite pads?

I used Steel wool Very Fine #0000

Notice a difference in performance after you did that hyp?

Here is something to think about, would you sand the rotors on your 1:1 so it stops better? I know it's not the same lol, but it will reduce the life of the shoes if the bell has a rough surface. Clean and free of oil or grease is all you need.

 

[Larsenracing]

I have to agree Pure.

NOT AT ALL... Read a article in Xtreme R/C about it. Pure is right on the money though.

 

[MikeK1981]

So 'no' on the emery cloth and 'yes' on scotch brite pad, got it! Just to add to that, the brakes on a 1:1 have one smooth surface (rotors) and one rough surface (pads) though. The CB and shoes in the savvy could be two smooth surfaces spinning against each other. You are right about the pads wearing faster if the CB had any texture to it but by that theory they would grip better... for a while LOL.

i think he's saying NO on anything.. lol

 

[MikeK1981]

Well the scotch brite would basically be just clean it off. It's not really hard enough to wear on the metal I wouldn't think.

 

[Purenitro]

Scotch bright would be fine, for what it's worth I can't remember the last time I "dressed" a bell, I'm sure I would see issues if it was required.

i use emery cloth to get off the glazed up materail on my bells. no issues and ive been doing it since day one

 

[MikeK1981]

What do you guys think happened to my clutch then that was causing it to slip a little more than it was at the beginning of that run? Think it just got glazed and needs to be cleaned? I can't think of anything it could have been. It sounded like when the slipper is functioning except there is a brand new pad in and it is tightened down. Plus I think it would have been worse if anything went wrong with the slipper, like I said it would still go fast and wheely but it was like it had to try a lot harder to get the front wheels up. It happened over a short period of time also. It was running fine and within 5 minutes, on the same tank of fuel, it was doing that.

Did you change your CB bearings at the same time?

 

[MikeK1981]

No but if I spin the CB with my fingers it is super smooth and spins for days so I figured they were still good. I'll check them again when I get the motor next this time. What size are they, in case I need to replace them? Anybody have a link handy?
