Default VW mechanical question

Hi , Any VW mechanics out there that may help THTer. ----Grandson has 98 Jetta 4 cyl gas,manual shift /w cable clutch. ------Depressed clutch and pedal went to floor. the cable is good not broke or disconnected.The clucth is fully engaged,but the shift-rod lever moves its full range,like it was dis-engaging the clutch,but the clutch is engaged. I can manually move the clutch-rod lever on trans it's full range without any resistance?? I'm wondering if the disc may be seized,glazed? I asked grandson if he heated up the clutch trying to get out of deep snow, but you know,KIDS? ! ! Thanks for any input. Clutch was strong no slippage before this . Even now you can start vehicle in gear and stall it with no slipping.

The disc can stick/freeze to either the flywheel or the pressure plate. I've seen 'em rust together. Often cranking them in gear with the clutch depressed will break them loose.

Sounds like the clutch is toast.. Tell the kid, lesson one and tell him next time, he pays or walks!

I'd bet the springs are gone on the pressure plate and therefore not grabbing much, what little is grabbing is likely glazed and not doing much either (slipping). A little slipping leads to a lot of slipping!

Try adjusting the cable if you can.. Otherwise, it's probably clutch time!

The clutch fork(the lever) is busted inside the bellhousing. Looks fine from the outside but fails beyond the pivot. It's usually an indication that the throw-out bearing's not functioning well and also may be due to an aged pressure-plate.Happened to two of my Volvos. It's going to require a tear-down so you may as well replace the whole works.

How many miles? If over 150K it's overdo anyway.

Just read 'no resistance"..either the fork like Ghost says, or the throwout bearing is toast and disintegrated. Something is not depressing the fingers or the nacelle on the pressure plate. Looks like clutch time.

thanks for all the input. I know either way it will have to be torn apart.I just figured if the clutch was engaged, there would be resistance on the lever that pushes the preassure plate in, but there is no resistance. ?

I agree it is a clutch fork or throwout bearing problem. Either way you will need to take out the trans. Funny things happen to clutches when youngsters drive them so either way when it's out replace everything

It almost seems like the release rod has punctured the plate. The clutch is engaged and the lever that moves the rod moves up all the way with no resistance, or at least as easy as one in a tranny not even installed in a car(i know because i have an old one on the ground) car had a bad tranny when we got it. We replaced it 15-20 k ago was fine till the clutch thing the other day.

Allwhet On the back of the trany there is a cover i believe its green pry it off and you will probably find
the clutch rod pierced the release bearing. Very easy fix,no need to pull trany, happens all the time on these
models. Replace bearing,rod and cover. Parts about $25.00, Time about an hour or less. Its not always
the kids fault.

I am going to pop that cover off tomorrow and see if that is the problem. That will be an easy fix if thats it. Is that rod piercing the bearing a rare thing, or does it happen more often than that?

Ich weiß nicht nichts über die Reparatur der fremden Autos. Sie müssen einen professionellen Mechaniker sehen und aus der Nase zahlen. Verbessern Sie schon, kaufen Sie ein Anerican Auto und helfen Sie unserer gestörten Wirtschaft.
