Competition sled pulling = hard on pilot/throwout bearings?

[HoleshotHolset]

I just had a thought while reading another thread regarding a pilot/throwout bearing...



Have any of you sled pulling folks had an abnormal amount of failures or issues with your pilot/throwout bearings due to slipping the clutch at the starting line @ high RPM all the time?



Perhaps this is where the Kevlar jobbie comes into play...



Thanks,

Matt,

As long as I don't dump the clutch over 9 grand the kevlar bearing works great:--)

Thanks for the input, Bob.



The lack of response in this (or any thread... ) can indicate a few things - arranged in the order of most likely to least likely reason:



1) People know something and ain't talking...

2) People don't know...

3) The original issue hasn't been much of a problem and nobody's talking...

4) The knowing ignore Holeshots posts 95% of the time, becasue they have other things to do, and most of his posts are NONSENSE!!!





I have not had any failures, or seen abnormal wear.



However, I would assume, your logic is correct, the high rpm for sustained periods of disenagament would have to invite premature throwout bearing wear. I just haven't hit that point yet.

Thanks Gene. Are you running an EEP or an OEM bearing?

EEP sealed roller bearing now. Before that, needle bearing.

So Matt, is it the new 98 or the old 94 that is getting built into the monster of all monster pulling trucks?

The '98 will get hooked to a sled at some point in its life... but I doubt it will be competitive... especially if J. R. rides with me. :-laf



As usual, I'm trying to plan ahead. The old NV-4500 is going to get treated to some shafts and someone's dual-disk clutch... probably not this year, though.



Matt - ain't afraid of a noisy clutch
