Changed clutch/flywheel/release bearing...still smells of burning?

2000 Hyundai Accent

Putting clutch in and trying to put in first gear is almost impossible to put in the majority of the time. After accelerating, putting in clutch and trying to shift into second it also can be difficult.. and sometimes sounds of rattling and you can feel some vibrating. Every other gear seems ok. Could it be something else that is wrong? Seems to feel the same as before the clutch was changed except that reverse works better now. I've read also about a pulse generator (considering my car apparently goes through a lot of these)...any ideas?

How about adjustment??? If there is an adjustment, it could be too loose (or too tight) . I would go for too tight first! Because if the throwout bearing is still %26quot;bearing%26quot; on the clutch release %26quot;spring(s)%26quot; and I mean %26quot;really hard%26quot;,--- it will possibly still make the input shaft of transmission continue to turn when you have the clutch %26quot;down%26quot;, - and at the same time be loose enough that the clutch slips while you are driving (hence the smell). Remember that if you put in new clutch plagte, (and the old one was really worn down to nothing), - it is going to be the equivalent of holding your foot down on the clutch a little (making it slip), -- if the throwout bearing is riding on the %26quot;release%26quot;, - it is turning all the time ( possible reason for rattling and noise). I have never seen one that drives at all this way, (usually it won't %26quot;pull at all%26quot;), however I would guess this is possible, first of all the %26quot;new flywheel may be a little bit %26quot;thicker%26quot; and of course the %26quot;plate%26quot; will be thicker, - and the pressure plate may have higher %26quot;throwout %26quot;fingers%26quot; or (contact area in case of %26quot;flat plate spring type)-- Such as right pressure plate (or even wrong one), - but made by a different manufacturer.



Normally %26quot;too loose%26quot; adjustment of clutch would make the transmission hard to shift out of neutral (depending on how %26quot;loose%26quot; it is, - -- at this sort of operation I would say it would be almost %26quot;tight enough%26quot;, -- because if it was real loose, it would not work at all, --(meannig you could not even start car in gear with clutch down)! It would act as if you didn't have the pedal pushed down,- (and would not smell, because it could not %26quot;slip at all%26quot;)!



So first thing I would do is disconnect linkage to the clutch at transmission, - (put car in neutral), start engine and see if it still makes the same noises and vibrations. If it sounds like %26quot;normal%26quot; (as it did before clutch replacement), then %26quot;adjustment%26quot; is your problem. ... However if the noise is still there, - then something is wrong either inside the transmission, - or the pilot bearing is wrong,- or there was still something still in behind pilot bearing when you replaced it, and it is fitting in too %26quot;tight%26quot; (as if the shaft were too long and hitting at end of pilot %26quot;stub%26quot;)!



I am assuming that the origional flywheel is still in use?? If you had to take it off, did you torque it down to the right specifications?- Did you have to remove it to get pilot bearing out, (or did you even change the pilot bearing)?? Pilot bearing is the small bearing in rear of engine, (either in the flywheel, or in rear of crank flange), There is a small peg or %26quot;pin%26quot; that is on the end of the shaft out of transmission that %26quot;plugs%26quot; into this bearing and keeps the shaft running streight when pedal is pushed down and clutch is not engaged, --------- it will be noisy when pedal down, if it is bad!



So you have a number of things that may or may not be wrong, which is going to need a %26quot;methodical check%26quot;.

If you aren't too mechanically inclined,- you may want to get somebody with more knowledge to check this out for you!



If you put it in yourself, - - stop and anylize everything carefully, and start emliminating possibilities one at a time till you arrive at a %26quot;most likely%26quot; conclusion! If you have have no choice but to take it out and start all over again.... make sure the %26quot;noise/vibration%26quot; is not in the transmission (and just an added problem - besides clutch), - because it would be a real pain to have to take it out another time to get transmission fixed too!



It takes a long time to explain it all, but you need to understand exactly what is happeniing and why,- in order to find problem, and fix it!

First off, a pulc generator, is for the ignition, and wont cause your problem. It dound like a shift fork, or sinkro problem in your transmission. I ou arent skilled at them, then i would suggest taking it to someone who is.
might not be the wheel system.

Check the Engine Support.
