Clutch problems Nissan Terrano D22 2007

Hello everyone, I need if someone could help me with a problem that has been presenting to me, I am fond of mechanics but I do not want to put my hands where I should not, for a few months I have noticed that it costs a little to pass changes in my terrano d22 2007 (yd25), sometimes they come to scratch the gears if I do not pass them quick A afternoons When it has been exposed to the heat of the sun, the problem is already solved and the changes have a good time but it must also be put in depth, everything indicates that it can be the hydraulic system of the clutch, my question is, with these symptoms, I will have to replace the clutch fluid, or it may be that my problem is in the press or clutch spider or in the worst case in the hydraulic pumps of the system, as I can discard the system What are less laborious about disarmament?

For your attention thank you very much ...

I think that model carries the brake fluid and the clutch of everything together. In the clutch bombin you will have a bleeding near the bloody gearbox in case it has air. If it does not improve then there is no other to change clutch.

Speaking of something else Nissan's D22 engine has the oil failure, always tries to take the oil level to the maximum or your number 4 cylinder will die.

If the valvulina is very dense (EP 90) and above it is very dirty, it is possible that in cold the marches will enter, try another less dense 70W 80, for example. And I would not come badly to change it, I believe that if you had any cylinder with a leakage, I would very soft the pedal, it would not be raging, in addition to lowering the level of brake fluid because of the leak, look to see if they "stain" the bombines, and purgal them as the partner says.

To test it is easy if the pedal is very soft when stepping on it, then you have problems or with the pump or with the cylinder, if the liquid is black and bisco then you must change it and in an event to check the cylinder, now first check the level of the liquid that if it is under that is the problem, the other thing you can do is look at the auxiliary cylinder while someone steps on the pedal and see how much By sircuito if it moves well, that is, Avansa should then be clutch kit.

I changed the brake fluid that wears and the repair kit of both cylinders and works wonders but finally the problem was not that, the thrust bearing was about to die and yesterday died, when you remove the powder protector from the tip of the clutch fork and see inward I find that the thrust bearing was all disassemble clutch kit of that truck since I have gone a lot and I have not found anything about it ...
