SwissZ Posted August 13, 2014 Share Posted August 13, 2014 Finally got to blast the 370 up the Autobahn and yes the clutch pedal dropped to the floor after about 10 mins hard driving. Got it up to 265 kph on the clock and apart from the roadster noise (can't remember the 350 being as loud) all was good. After a few change downs and hard acceleration the pedal came only half way up. Gears still went in no problem at this point but eventually the pedal stayed down and I was struggling to get a gear in. I could pull the pedal back up, but if I touched it lightly it got sucked back down! Slowed down for a few mins and all was good again for about 10 mins when it started again. Back in Switzerland at normal speeds, the car's perfectly fine.... If this was the first time I'd had this, fair enough, but I had the same thing with my old 350 and also with an Infiniti G37 which were both bought new so no wear and tear there. The 370's a 2010 with no official warranty but the dealer gave me a 1 year extension. Wonder what he'll say about this Quote Link to comment Share on other sites More sharing options...
Ewen@Clark Motorsport Posted August 13, 2014 Share Posted August 13, 2014 Sounds like the concentric slave cylinder, carried over from the 350Z HR which is a common failure point 1 Quote Link to comment Share on other sites More sharing options...
4RE Leather Posted August 13, 2014 Share Posted August 13, 2014 This is 3 days on the trot someone is having the same issues. Since mine was changed for the upgrade its been great. Quote Link to comment Share on other sites More sharing options...
SwissZ Posted August 13, 2014 Author Share Posted August 13, 2014 Sounds like the concentric slave cylinder, carried over from the 350Z HR which is a common failure point I keep seeing this as a solution on here but the last 2 cars were brand new (run in periods completed religiously) so is there a problem with the original design? This is 3 days on the trot someone is having the same issues. Since mine was changed for the upgrade its been great. Hopefully this answers my question. Do you have details of what was changed? Maybe part numbers I can throw at the dealer? Cheers Quote Link to comment Share on other sites More sharing options...
4RE Leather Posted August 13, 2014 Share Posted August 13, 2014 MIne had done 16,000 but it went soon after the supercharger was installed. Phone up http://www.abbeymotorsport.co.uk as they changed mine. Its not cheap as its a lot of labour charge. I think in total it came to about £700 without checking the invoice.

4RE Leather Posted August 13, 2014 Share Posted August 13, 2014 (edited) This is what the 350 hr 370 UPRATED one looks like. Edited August 18, 2014 by 4RE Leather Quote Link to comment Share on other sites More sharing options...
Ewen@Clark Motorsport Posted August 13, 2014 Share Posted August 13, 2014 It was a poor design that Nissan half admitted was an issue on the 350Z HR, why they continued with it on the 370Z I don't know but some have been changed under warranty on both cars. Uprated aftermarket ones are available but are around £350 Quote Link to comment Share on other sites More sharing options...
AliveBoy Posted August 13, 2014 Share Posted August 13, 2014 So glad I got a DE! Mine was £80 new and took about half an hour to change! The symptoms were the same for me though, good luck 1 Quote Link to comment Share on other sites More sharing options...
SwissZ Posted August 13, 2014 Author Share Posted August 13, 2014 I'm going to see what the dealer says first. Pees me off that I might have to pay for a fault that is obviously down to a poorly performing original part. Quote Link to comment Share on other sites More sharing options...

Pees me off that I might have to pay for a fault that is obviously down to a poorly performing original part. As I said on a previous thread. When they go the seals make the brake fluid start to darken. Look for a black residue at the top of your filler bottle Quote Link to comment Share on other sites More sharing options...

370Ad Posted August 29, 2014 Share Posted August 29, 2014 Try the fluid first as you could have boiled it and got air in the system. Quote Link to comment Share on other sites More sharing options...

I'm guessing labour for dropping the box and the uprated slave. Sounds about right to me. Concentric slave is a bit of a bugger......it's as much of a job as changing the clutch (which autodata books out at 9 hours). Quote Link to comment Share on other sites More sharing options...

Dave Bull Posted September 1, 2014 Share Posted September 1, 2014 I'm live just outside of Glasgow! Guess being a truck tech' and having a motorsport background helps! It's usually a case of get it fixed yesterday Dave or else get your jacket and tools, and get to f**k, so yeah, moving fast is a priority...LOL! Seriously though, I actually thought that taking the 350Z gearbox out was one of the easiest ones I had ever done! I'm used to gearboxes that weigh 350 kgs and have the World attached to them, so the 350Z setup was fun to work on, rather than a task!
