Hi
I have a 1990 volvo 240 DL -M47 manual . When I change into reverse gear I get this grazing of cluth . I read all the material and found that one should first adjust the cluth cable.
What is the procedure to do it (could not find it) . The 1st and 2nd are stubborn some times and there are some vibrations when shifting from 4th to 3rd, but these do not have grazing issue.
How should I check whether the cluth is worn or not. I used to think that first sign of worn cluth is that it slips under load.
I checked it by first applying the handbrake on and then putting the car in 2nd gear . I released the cluth and the car died and there was no increase in engine rpm. I think this is the expected behaviour so is it cluth cable.
What are your suggestions on this procedure and conclusion.

Another observation is that when I am driving in 2nd gear at 30-40 over very bumpy roads then RPM suddenly increase (cluth slips ?) for a second or two,but ofcourse I done only 3-4 times.


I plan to change the fluid to redline. So far I have put cheap type F for flushing purpose.
