omega36 Posted June 3, 2009 Share Posted June 3, 2009 Ello. I have a bit of a problem with me clutch/gearbox - 1st is very difficult to select, and 2nd also gives me trouble (and even 3rd slightly shows some resistance) but especially the reverse gear.. Now I'm quite sure it's not the gearbox (?) as I initially thought, but more the clutch - the reason I say this is that even though the clutch is fully pressed down, when I select reverse (eventually after quite a struggle), it feels as if the gear is now engaged as the car starts to move slowly (on a flat plain). Also, my clutch has recently become (more) heavy... so the problem wouldn't be simple like a stretched clutch cable would it? It's a GTR, so it can't be a simple problem..... Anyway - the car is off to the mechanic tomorrow, would like to just have some idea of what it may be before I take it there. Cheers for your help!

You can do it yourself with a 12 & 14mm socket, a phillips screwdriver, a pair of pliers, and a rebuild kit for about $15-20 for each. Piece of cake.

ezy_09s Posted June 3, 2009 Share Posted June 3, 2009 wont be a stretched cable since it is hydraulic...check to see if the slave is actually pushing the fork to full engagement.

SIR-032 Posted June 3, 2009 Share Posted June 3, 2009 Either air in the Clutch Slave cylinder (not fully pushing out, hence clutch not fully disengaged) OR The begginings of collapsed Pressure plate Springs so new clutch Link to comment https://www.sau.com.au/forums/topic/273071-r32-gtr-very-difficult-to-select-gears/#findComment-4635520 Share on other sites More sharing options...
omega36 Posted June 4, 2009 Author Share Posted June 4, 2009 Hey guys - We actually found that the clutch booster cylinder has split so there's an air leak there, so that's being replaced. Also getting my leaking ABS unit replaced as I assume the brake master cylinder also needs to come out of the way for the clutch booster cylinder to be replaced. I hope there isn't a problem with the clutch's pressure plate as well The GTR strikes the bank again Link to comment https://www.sau.com.au/forums/topic/273071-r32-gtr-very-difficult-to-select-gears/#findComment-4635615 Share on other sites More sharing options...

Monky Posted June 9, 2009 Share Posted June 9, 2009 Yeah what was the verdict I have the exact same problem, 1st and reverse are almost impossible which makes traffic lights interesting. Can you let us know what it was, from what I have ready usually clutch related i.e worn cover, pressure plate or both. I'm running a OS Giken twin plate which has already been refurbished back in 2006, loooks like it's time again!

paulR32gtr Posted June 9, 2009 Share Posted June 9, 2009 I had a similar problem with my previous clutch. I had a leaking slave cylinder so had that replaced. When they installed it they didn't bleed the clutch fluid properly, I noticed it was a little crunchy on the way home when I picked it up but kinda came and went. Had zero time to do it myself, and the workshop were too far away, so kept driving, clutch pedal kept getting heavier and heavier, hard to get into gears sometimes. Clutch wore out as it wasn't disengaging completely, then pivot ball snapped and fell out the bottom one day. New clutch for me. Had a lot of other stuff being done around the same time so new clutch made sense anyway - thats how I justify it....

Monky Posted June 9, 2009 Share Posted June 9, 2009 Thanks for the reply Paul, do you think having air in the system contributed to your clutch failure or would you say it was worn regardless? I'll have a look at my slave and master shortly and see anything dodgy. My car is running just shy of 600hp so it's possible mine is just worn from use.

DS-ZILR Posted June 9, 2009 Share Posted June 9, 2009 must be the season for failing clutch boosters mine has a nice split through it! im after a new one anyone got a source for em? also heard you can use some model nevara clutch master cylinder and clutch booster dont suppose anyone has more info on this? cheers crew Dion Link to comment https://www.sau.com.au/forums/topic/273071-r32-gtr-very-difficult-to-select-gears/#findComment-4645785 Share on other sites More sharing options...
paulR32gtr Posted June 9, 2009 Share Posted June 9, 2009 Monky said: would you say it was worn regardless? Nah the clutch was in good condition, was not too old and didn't go out in the usual way. It was either air in the fluid or the clutch fork & pivot were not aligned properly causing the crunch, and ultimately caused the pivot to fail. 600hp eh... yeah I imagine you would move through clutches fairly regularly. Better than gearboxes or driveshafts.
