    Shredded clutch bell

    So if you run a steel spur gear, or are thinking about getting one, watch out for this. It apparently wasnt the mesh like a thought it was, ended up being i had my slipper set to tight. ha some how i had an extra clutch bell so i can still drive tomorrow. but dang this is just nasty.

    If you run a steel spur gear, you have to run a hardened clutch bell as well. Otherwise,^^^^^will happen every time.

    +1 Your regular stock clutchbell will not hold up to a hardened steel spur gear...

    I'm running a RR 19T cb with a stock 54T spur......no problems yet. Which I run the slipper slightly loose. I play in mostly diRt.

    Well the spur gear looks like this no problems at all. my slipper is super loose now, cuz i dont wanna do it again. However if i get the money i will probably buy a hardened CB just to save some time and worries down the road.

    And just for some of my own knowledge, anyone out there that is running a steel spur gear. What clutch bell do you have and how many turns out from fully compressed is your slipper? just curious

    The problem with running a hardened steel clutch bell and spur is the next weak points in line are inside the transmission. BUT, I have an all steel driveline from the clutch bell to the wheels and couldn't be happier. Haven't had anything break, strip, or twist yet and I guess I'm about as rough on these things as you can get. I have no mercy.

    Oh yea, I keep my slipper tight enough that it will only slip under extreme loads, but I use different slipper pads than anyone else. So my slipper applications don't really apply to anyone else.

    to set my slipper I always set it loose....so it WILL slip, then gradually turn it in until its at the desired point. If it stops turning (all the way tight) back it out an 1/8t or so. Like Mark said, if you run it all the way tight, with hardened gears, next it'll be your trans. Robinson Racing makes a good cb and in a lot of sizes. http://www.robinsonracing.com/catalog/catalog.html#

    The slipper setting will not save the stock bell from being eaten by the hardened steel spur. With a perfect mesh the stock bell may last for a while; if its not perfect, it will look like the bell in the 1st post in short time.
    No slipper/tall gearing/power = broken parts.

    I know for right now it seems to be doing fine, i ran it quite a bit and all seems fine for now. however im sure after a while it will look like the first one and if so i may be a new hard cb or buy a nother stock one and go back to the plastic spur gear. rather replace those then destroy something else more expensive in the drive line.

    I agree....thats why I run the stock plastic spur gear. I have another just in case, but haven't had to use it yet. Its been a year and a half.

    The Spur is hardened steel the stock CB is not.... If you are going to use a steel spur you need to get a hardened steel CB and that won't happen...

    I ended up going down to my LHS and bought a couple plastic spur gears. When they are as cheap as they are id rather burn through those then burn through clutch bells or pay the extra money for them.
