nissan 240sx ka24e tanny problem

[kennymillsjr]

ok i have a nissan 240sx converted to a oval track racecar..i run my race today..when i pulled in i put it in neutral and let the clutch out...and i heard a noise that sounded kinda like a grinding...it dosent do this when clutch is in..and it sounded like it was coming from the bell housing....i just put a new duralast clutch and throw out bearing in it..so any ideas of what this could be?

or it sounds like a clicking like somethings spinning and at every rotation you hear it click

I had a something like that happen to mine ( also a circle track 240 ) The clutch didn't have enough freeplay, the throwout bearing stayed in contact with the pressure plate fingers. The throwout bearing eventually locked up and seized on the input sleeve. The small explosion actually put a small hole in the bellhousing. On the next trany I put a return spring on the clutch arm to assist the slave cylinder return.

Kenny, get on Lonesome Pine Raceway's web site. We have a big race later this year, $1000 to win if we have over 40 cars. The class is Pure 4 if you want to check the rules. It's a long pull, but I pulled to Orange Co. in 2006 to race in the Mod Mini Madness races (and won) They might still remember the old beat up gray 240 that was running 2nd when the local car running 1st place had to drop out with a bad tire.Come on over, and tell your local racers.
