clutch problem?

[wickednasty]

Peeps, ano po kaya culprit pag tnatapakan ko clutch, may parang sound ng air brake na maririnig galing sa engine. parang squeaking noise na sinabayan ng hangin.... wala naman effect sa driving pati sa shifting ng gear.. nakakairita lang pakinggan yung tunog although maririnig lang nman pag nagddrive ng bukas yung window... problem kaya to sa clutch?

thanks in advance...

Youve got a turbo, sounds like there might be a small hole that is opening up when you depress your pedal and letting a small amount of air in it. Or does it make the same sound at low speeds? Try listening at 2 vary different speeds and seeing if they sound alike or different. Or could have been a vacuum leak or hydraulic fluid leak(see if fluid okey or leaking down onto the pedal ).

If the noise is only heard when you depress the clutch and disappears when you release it, I'm almost certain that it's a bad pilot bearing.

I experienced exactly the same thing. It's the clutch release bearing. Lalakas ng lalakas tunog niyan. Tapos unt-unti, magkakaroon na ng shudder. Finally, one day your clutch just won't release when you change gear. You can still shift because you can still depress the clutch. But when you lift your foot from the pedal, hindi sasama pabalik. You have to pump it up and down to make it release. At pag nag release, bigla yung jolt.

Better have it checked now before it damages your pressure plate. Yung sa akin kasi okay pa sana yung pressure plate at saka kapal pa ng clutch disk. Pero yung gitna ng pressure plate na tumatama doon sa bearing napudpod kasi ayaw na nga sumama paikot noong bearing.

Most likely cause niyan is water that seeped into your bell housing. Yung sa akin kasi ilang beses na nagri-river crossing.

thanks sa mga reply peeps.. actually ganun nga yung prob.. maririnig yung tunog pag tnatapakan yung clutch then nawawala pag bitaw. another weird sound na naririnig ko, pag tnatapakan yung clutch may squeaking sound galing sa pedal, pero nung pinatingin ko sa mechanic, he just sprayed wd40 somewhere dun sa end ng pedal, nawala na.. then after a week bumalik nanaman.. but what made it weird is minsan wala yung squeak, minsan meron.. related din kaya to sa mga possible culprits na namention nyo above?

The main symptom of a bad release bearing is if the noise is heard while the clutch pedal is released (clutch plate is engaged). I think the OP experienced the opposite problem, in that, the noise only happens when the clutch pedal is depressed (clutch plate is disengaged).

While the clutch pedal is depressed, the release bearing is not rotating with the engine, so I think it's unlikely that the release bearing is causing the noise.

im quite positive na naririnig yung sound when disengaging the clutch (pedal pressed). kasi nung first time ko narinig to was when shifting to neutral to do a full stop. but i dont get to experience shuddering when accelerating from a full stop. just the same, when disengaging the clutch to shift to 1st gear, andun nanaman yung tunog... badly need to have this fixed kasi medyo nakakaparanoid gamitin yung kotse sa long drive. laguna to qc pa naman ako madalas. yoko ma-tow or makadagdag ng traffic sa edsa pag nagkataon.. hehe

may mairerecommend ba kayo na magaling na repair shop for this? preferrably sa south pero ok lang rin kahit sa north...

much thanks to everyone who replied...

Yup, mukhang pilot bearing/bushing nga.

WD40 is not meant for long-term lubrication... it is used primarily to displace water and as a penetrant to dislodge stuck metal items like tools, hinges, nuts & bolts, etc. WD40 only leaves a light lubricant and it easily dries up. Use silicon spray or grease instead.

kailangan talaga maipasyal mo sa mechanic yan para mapinpoint kung saan nagmumula yung tunog

YOU SOLVED THE PROBLEM! WD40 is only a temporary lube, and since after you spray some lube on the pivot point of the pedal and the squeak stopped, you figured the problem out. It (the pivot point of the pedal) needs to be cleaned and greased. Done deal. Good job on saving yourself a lot of money!

He half-way solved noise no. 2.

Noise no. 1 is still there.

The main symptom of a bad release bearing is if the noise is heard while the clutch pedal is released (clutch plate is engaged). I think the OP experienced the opposite problem, in that, the noise only happens when the clutch pedal is depressed (clutch plate is disengaged).

While the clutch pedal is depressed, the release bearing is not rotating with the engine, so I think it's unlikely that the release bearing is causing the noise.

When you depress the clutch, the bearing should actually spin together with the center of the pressure plate. If it is worn out and does not spin properly, it wears out the diaphragm spring in the center of the pressure plate.

Here's a description from "How Stuff Works":

"Another problem associated with clutches is a worn throw-out bearing, sometimes called a clutch release bearing. This bearing applies force to the fingers of the spinning pressure plate to release the clutch. If you hear a rumbling sound when the clutch engages, you might have a problem with the throw-out.


[SIZE=+1]Clutch Diagnostic Test[/SIZE]

[SIZE=-1]If you find that your clutch has failed, here is an at-home diagnostic test that anyone can perform:[/SIZE]

1. [SIZE=2]Start your car, set the parking break, and put the car in neutral. [/SIZE]
2. [SIZE=2]With your car idling, listen for a growling noise without pushing the clutch in. If you hear something, it's most likely a problem with the transmission. If you don't hear a noise, proceed to step three.[/SIZE]
3. [SIZE=2]With the car still in neutral, begin to push the clutch and listen for noise. If you hear a chirping noise as you press, it's most likely the clutch release, or throw-out bearing. If you don't hear a noise, proceed to step four.[/SIZE]
4. [SIZE=2]Push the clutch all the way to the floor. If you hear a squealing noise, it's probably the pilot bearing or bushing.[/SIZE]

[SIZE=2]If you don't hear any noise during these four steps, then your problem is probably not the clutch. If you hear the noise at idle and it goes away when the clutch is pressed, it may be an issue in the contact point between the fork and pivot ball.[/SIZE]

[oj88]

[SIZE=2]3. With the car still in neutral, begin to push the clutch and listen for noise. If you hear a chirping noise as you press, it's most likely the clutch release, or throw-out bearing. If you don't hear a noise, proceed to step four.[/SIZE]

[SIZE=2]4. Push the clutch all the way to the floor. If you hear a squealing noise, it's probably the pilot bearing or bushing.[/SIZE]

You're probably right. But I think it could also be semantics.... the OP needs to confirm if the noise is heard WHILE he's stepping on the clutch or AFTER.

If the noise appears WHILE the the pedal is being depressed, that's the release bearing. This would be #3 symptom above.

But if the noise appears immediately AFTER the pedal has been depressed, that's the pilot bearing/bushing. This would be the #4 symptom.

The way I understood his post is that the noise appears when the clutch pedal is held down.

[FWC]

You're right. Dapat mas precise ang description.

mga sir ask ko lang sana about sa starex namin kasi pg narelease mo na ung clutch especially in 1st gear my sound na "GRRRRRRRR" hindi nman sy masyado malakas kya lng nkakairita pkinggan. pinapalitan ko n ung support nung propeller pero dprin nawala.pinatingnan ko na rin pero d mapin point kasi maririnig mo lang sy sa medyo kulob na lugar like sa garage. pag tinapakan ang clutch wala naman problem sk khit naka 2nd gear wala rin.maririnig mo lang kapag mabagal ang andar ng 1st gear. ayoko lng din kasi lumaki ang problem.sk baka abutan pako sa byahe.baka may experience na kayo or idea about that.maraming thanks in advance!

hi peeps pasingit na din since clutch naman ang topic dito ...


yung sa akin naman ganito ang symptoms kapag malamig pa yung car(pajero 97' 4D56 diesel) kapag nagpalit ng gear parang sliding clutch ang tunog "hinngggg" basta sliding ang dating ng tunog parang sabay mo tinapakan ang clutch at gas pedal pero all the way release ang gas pedal ko ...then after a couple km or mga 10 mins. or so wala ng prob good to go and normal na normal na ulit ang takbo no more weird sliding clutch sound ano po kaya prob? thanks for your time......

i had a almost similar problem..if malamig difficult to shift, my mechanic suggested that i replace the clutch assembly. i did and so far its ok naman.

my question is i hope mga experts can help give their views. i bought a seiken clutch master assembly. sabi kasi its a good replacement.
auto supply ask me if aluminum or steel, oem is aluminum. i bought the steel one coz its cheaper.
ano difference? which is more durable? somebody told me yung steel na clutch master mas mbilis daw mapudpod yung rubber sa clutch master.

please give insights. thanks
