does this destroy throwout bearings with the extended amount of time we are using the bearing.

i am needing to replace mine due to squeling when the clutch it applied, and i have notice it has a grove cut in it now that isnt suppose to be there

 

Nope. The wear will generally come when the clutch is depressed all the way to the floor

 

life span is what a season of racing then

 

i didnt notice any wear to mine after 2 years of beating the hell out of it. i only replace mine when i replace my clutches.

 

what transmissiona re you on a hydro with a stop

im on a cable with hydro internals, and figure this is where my issue is with the cable

 

also a twin disk not a single

 

I put some used one in my trans that I have no idea how long it got ran before i got my hands on it. Full hydro set up with a stop.

 

yah in a cable it has been adjusted a few times so it probly throws a little further now.

guess i need to measure my plates lol

 

The fins on the pp dig into the bearing sometimes.. no biggie

 

Yeah as far as I know wear is when the clutch is pressed and fully riding on the fingers. Like people that hold the clutch down at stop lights rather than neutral. Heck I know people that don't even use their brake to hold them at a light but just keep riding the clutch. One thing I can say about preloading is to not hold it. I made that amateur mistake and glazed my TODA flywheel and pressure plate to where I'm not sure a resurface would fix it lol. I was so into it when I first learned and tried it out that I would go to the line and already start it well before the launch.

Now I deep stage with the first lights on, make sure the other person is up to the line too, then preload and slightly slip it just make the 2nd light come on. I make sure it holds that way so when I go to rev before the launch it doesn't slip and red light. Then I back the revs down until the first light starts, rev and go! Obviously if I were on a pro tree I'd preload fully and rev when the 2nd staging lights come on. Happy launching!
