Re: 1983 sj 800cc 4 stroke 4x4
Hi fathercuda, This grinding noise you have is it consistant through 1-3 in other words is it just when it goes into gear or all the way through to your next shift? also when in neutral do you hear it and if so when you push on the clutch does it stop? This could be a throw out bearing or sincro mesh problem, I am leaning towards the throw out bearing,not a hard fix but a bit of work involved please get back to me with the requested information and see if we can resolve this issue for you good luck

the gear grinding noise is because the clutch plate is not fully disengaging and the input shaft is still driving. If you did not use the same length of push rod then the slave cylinder is not moving enough to disengage the clutch. Check it out that with the pedal on the floor the piston in the slave cylinder should be almost to the edge of the slave cylinder . That is where It should be to be working properly
Pull the gear box drain plug and check for heavy metal stuck to the magnet. I suspect that the clutch in-put shaft bearing has failed. If so you will have to have the gear box rebuilt as the metal will have affected the other bearings
What?! Really! The noise goes when the clutch pedal is depressed! So the noise goes when the release bearing (throw-out bearing) is engage? So how would that be a release bearing/clutch problem? If it didn't make a noise until the clutch pedal was depressed, it would be the release bearing! In other words its the input shaft bearing and/or counter shaft bearing in the gearbox. Stop giving people bad advice
This is more than likely an input cluster bearing beginning to fail. It could also be a sign that the gearbox is simply out of oil. Check oil level & if it is ok it is more than likely the input cluster bearing in the gearbox. Low oil is usually accompanied by gear noise which is usually more noticeable in 1st, 2nd & reverse. Input cluster noise is much less noticeable when in gear due to load on input shaft.
Sounds like the clutch cable or spring has gone, but seeing as it went gradually probably the spring. It basically means that the clutch plate isn't lifting from against the big end, the grinding noise being the fact that you're forcing the car in to gear when the input shaft is still spinning. If you don't know how to take the gearbox off yourself then take it to a dealer, the way to get it to drive for now would have to be to start the car in first, or have someone bump it, the carefully work your way in to third by matching the gears before pushing the gearstick in. This is quite difficult and can do damage to your gearbox so be careful if you do this, otherwise get it towed.
Does the car grind when you put it into reverse? If so, the clutch is not fully disengaging and needs to be most likely bled or adjusted. It Is the clutch hydraulic oil they changed, correct?
If it does not grind when putting into reverse, I would ask the shop that did the clutch if they changed the fluid in the trans. And if so, what fluid they used. Check your owners manual for the correct fluid specification.
Also if your clutch was replaced because it was dragging, not because of slipping, you may have done some damage to 2ed gear synchronizer causing this problem as well.
