Author Topic: probably pilot or throwout? (Read 6277 times)

BLACKDOG · « **on:** Apr 19, 2006, 08:34:36 PM »

Ok, got in my truck, start it up, and she is squealin!! IT only squeals when the clutch is out, and it sqeals whether I am in any gear, or nuetral.

I was thinking pilot or throwout, but when I dperess the clutch, the sound goes away, and the sound is only there when the pedal is all the way out. If I push the pedal in mabye half an inch, the sound goes away. This point is long past where the clutch engages and kills the motor when the clutch is released. from the feel of it, and from the point that the motor died, I think I have about 3" of play in my clutch pedal, but the sound goes away in the first 1/2" mabye the first 1"

any thoughts?

you pulled the clutch off ??

BLACKDOG · « **Reply #2 on:** Apr 19, 2006, 08:38:10 PM »

no, its still all together. I thought about just adjusting the pedal so it doesn't come out as far

79coyotefrg · « **Reply #3 on:** Apr 19, 2006, 08:40:22 PM »

has it done this for a while or just started today??

no dont adjust it up, you'll burn the throw out bearing up

its either the pilot bearing is toast or input bearing in the front of tranny

BLACKDOG · « **Reply #5 on:** Apr 19, 2006, 08:43:35 PM »

I've heard the squealing before, but it was very intermittent, and not very loud. I thought it was my powersteering pump, which is bad. Today was the first day that it was pretty much constant, and it was a lot louder. I'm pretty sure it is coming from the bellhousing area, or the tranny itself. It is shifting fine though, and the clutch isn't slipping, everything seems normal and tight. My tranny does fall out of 1st and 3rd, could this be the next step of a longterm problem? (ie synchros going out?)

I figured that'd be a bad idea

dude, it kinda sounds like your input bearing is spun dry, falling out of any gear is the first sign a rebuild is near

79coyotefrg · « **Reply #8 on:** Apr 19, 2006, 08:53:25 PM »

better pull the tranny tomorrow, you have a R150 right

79coyotefrg · « **Reply #9 on:** Apr 19, 2006, 08:55:24 PM »

i'll keep my fingers crossed but falling out of gear $I\'m Down$ dude you know its bad

Unfortunatly I'd say from your discription of when it is occuring, Glen would be dead on. Since it only occurs once you let the clutch out it has to be in the trans, usually a throw-out will squeal when you depress the clutch since that's when it spins. The bearings in the trans will stop spinning when you depress the clutch and will start once you start letting the clutch out.

i figured glen was right, he usually is (at least about my truck) but I always go for a 2nd opinion. Guess I should start looking for a spare tranny. $I\'m Down$

only original part of my drivetrain is gonna be my goldarned driveshafts and my t-case

Hey, rather it is your release or pilot bearing, the noise will go way when the pedal is RELEASED (clutch engaged). At that time, the pilot bearing is not spinning (since the trans input shaft is in a sense "locked" to the crankshaft) and the release bearing is just that, released!

Bad release or pilot bearings are only heard while the clutch pedal is pressed (clutch disengaged).

Sounds like something is up with your transmission to me... Here's a scary question: Is there any GEAR OIL in your trans??

at least, there better be. That is the only part of the truck that doesn't leak

I'll look tommorow. I checked all the fluids about 2 mos. ago, and it was fine then, so I doubt that is the problem, but I'll check.

If that isn't the case, guess I'd better start looking for a new tranny huh?

BigMike · « **Reply #18 on:** Apr 20, 2006, 12:20:08 AM »

I don't know.. don't jump to any conclusions just yet. How does it drive? Any difference in sound while on heavy throttle or just coasting?

not really, but the squealing is pretty loud in every gear except 4th. it is still there, but not as loud. It drives fine, shifts like normal, no slipping or grinding

It is possible that it could be the throwout bearing. I have seen it before. If it's just barely touching the clutch enough to spin it and it has a bad spot it will sqeal.

Now that is a correct symptom of a bad release bearing. But his does not make any sound until the clutch pedal is released.

the sound is only there when the pedal is all the way out.

He' got other issues, of a long time coming failure.

BLACKDOG · « **Reply #24 on:** Apr 20, 2006, 01:31:26 PM »

just went and checked, my tranny does have plenty of oil in it $I\'m Down$

Is there any possibility that the oil from my valve cover leak is getting into the bellhousing and causing this? I know that is very unlikely, seeing as oil is alubricant, and would quiet it down, but figured I'd throw it out there anyway

I didn't realize my valve cover was leakign that bad

i knew it was a little, but its gotten worse

guess I know what I'll be doing over the next few weeks

That's what I'm saying,without no pressure on the release bearing if it's touching the clutch enough to spin it if it's bad it can squeal.

If the squealing stops before the clutch is fully disengaged then it makes me think it's the release bearing.

BLACKDOG · « **Reply #26 on:** Apr 20, 2006, 02:51:18 PM »

this from a little different angle, I can reach in from the side, and grab the shift fork? (the thing the slave cylinder pushes on) when I put pressure on that (move it mabye 1/8") it'll stop squealing. We're not talking about a huge range where it is squealing here, not far at all

does that help at all?

79coyotefrg · « **Reply #27 on:** Apr 20, 2006, 04:44:18 PM »

try loosening the clutch up a little and see if it stops

Plowking · « **Reply #28 on:** Apr 20, 2006, 05:18:11 PM »

I have a spare trans laying around where you from blackdog?

Willy Mammoth · « **Reply #29 on:** Apr 20, 2006, 05:37:27 PM »

If you move the clutch fork closer to the slave and the noise goes away, it is the release bearing. Like Bubba said it may be locked up and dragging on the pressure plate. By moving the fork it stops touching and stops making the noise.

This means that the noise at least is not the trans.

Get the throw out bearing changed quick before it wares out the pressure plate fingers.
