Thought throw out bearing was making noise,replaced bearing and clutch, noise is exactly the same
bad diagnose.? (full clutch mean, with fly pilot bearing NEW?)
parked, are you parked, ? and idling,?
so here are the real tests, if parked. (moving can be CV noise or other things, braking or?)
So you think the TO bearing is bad. ok. , that is always FIRST.
1: i remove all parts connected to the TO bell lever, (SLAVE Cyl)
just unbolt the slave, leave hoses alone. see lever and bellows boot?
the lever is now free in the bell port, for me to play with it by hand.
Hand testing, i do that , because, stuff can fail in all these parts.
I can in fact move the lever too, and fro.
I can take off the boot and see what happening, i can see the insides.
I can see it touch or not touch the TO bearing. ( this is POWER )
The power of sight and actions....
i pull back on the lever such that there is huge play now , from the
lever internal fingers and the bearing, (in neutral idling)
the lever is NOT touching the TO bearing. (see end of post for hints)
no noise now?
yes, no noise, bad TO bearing.
no, i still have noise. (TO is not touching anything now and can not make noise. its some thing else, out comes my $% stethoscope.
ok say the noise is unchanged, touching or not (lever)
the other noise maker.?
is the fly wheel pilot. (there are others, but we look at each 1 by 1 in order.
The pilot can sing (noise) when in gear, clutch pedal to floor.
this cause the fly wheel to go fast and the pilot shaft in the tranny to be
stalled, and puts max stress on the pilot. make noise now?
and increases with RPM , yes, bingo , full clutch was not full clutch was it (ponder that)
ok that tests passes. TO good, pilot good.
we not attack the tranny.
So in Neutral, clutch pedal not depressed.
The transmission front pilot shaft is now spinning
you year noise.
you depress the pedal to the floor, and the noise stops.
yes, bad tranny.
when young i blew a clutch almost every race, seen ever failure possible. all.
with engine off and slave off.
im playing with the lever, i look down the hole (port)
and see the end of the lever, is it captive in the TO slider ring.
no bad install.
yes, is the TO sliding freely in the Pilot boss? or is the TO stuck or sticking, and is hard to retract the TO away from the PP pressure plate fingers? all these checks are hands on deal.
there are many checks to do, before jerking any gear box.
does the noise stop if you start a cold engine with all fan belts.
removed? then start engine and run for 2mins max?
yes, then its not the tranny.
its the P/S pump, A/c Compr. or the water pump or alternator bad.
i wish i was there, in 15min we;d have the source.
do ask questions, I have many .
