clutch question

[heavychevy72]

ok, i got a 72 lwb 4x4 with a 12 inch lift,running 42's my question is i've installed a 454 with a granny 4 speed with 488 gears,but i've got a little squealing noise,i think it might be pilot bearing,i replaced it, but it came from auto zone and i have got some bad parts from there before but could it be my clutch aint adjusted just right, i'm use to a hydrolic clutch any help would be gratefull, because i'm ready to tear it apart again,for the forth time

yeah got a high dollar clutch,bought from jegs proformance,but it makes the noise (i forgot to say before) until i just let my foot rest on the clutch pedel,not applying much pressure at all,some tell me the clutch aint adjusted right,then others pilot bearing,then others throw out bearing i guess just tear it apart,and put more new ones in???????

It's easy to adjust them. You want to be able to press the pedal in about 1.5 inches before the clutch engages (actually it will be disengaging). A good way to tell it's not adjusted correctly is that the pedal won't come out all the way and will stay "stuck" in the depressed position unless you pull it up with your hands. I've never heard any noises from my clutches so I couldn't tell you what that would be but if resting your foot on the clutch alleviates the problem then your throwout bearing would be a great place to start. I have run centerforce throwout bearing on two of my trucks (1977 ford f100 with 351Windsor) and my Blazer with no problems.

You didn't say if you had any body lift on that thing, if you do that might play a part in correst adjustment of your clutch since the linkage would have to be modified for the lift.

no body lift,just springs,i greased the Z-bar today ,where the ball goes in the block i don't think that will help but i really DON'T look ford to pulling all that back out ,i may just run it (big mud bog in georgia)in march,maybe it will either quit or break,i thank ya'll for the help and will try to return the help

if I was going to guess, I'd say its your throw out bearing since you mentioned that it goes away if you rest your foot on the pedal...

Good luck with it!

Throw out bearing is your problem.

What kind of linkage system are you using for the clutch?

Don't waste your money on a diaphram type clutch, (including Centerforce). Diaphram pressure plates won't last in a truck because of the heat.
Get a good Borg & Beck style 12 in clutch. I have a Ram in mine.
