well i pulled the gearbox out today
and you guys are guna laugh at me, because i actually suck lol
k40's and k50's have a small rubber boot that goes over the clutch fork on the outside of the bellhousing
i had installed this boot on the inside because i was like it wont matter which way it goes(coz at the time i didint realise they went on outside and i assumed it was inside because of the spring on the outside sort of being in the way.)
so yeah i installed it inside
so the rubber boot was rubbing against the pressure plate slightly creating the whirring, and then when the clutch was depressed it was pushed further against the plate createing the screeching noise!
lame, anyway when changing the clutch fork with another bfor putting the box back in(coz the other fork had a better end clip on it)
i accidently strecth my release bearing clips, so yay more fun for me lol
oh and 2moro or wednesday should be getin another brake booster
