Gtr Clutch Problems

[itbmils]

OK

I have an R32 GTR with about 300awkw – and I think my clutch may be going

I currently have a twin plate – 'cause I here it rattle every time I have the clutch on the floor (no it's not the spigot beating), but I don't have much (READ :ZERO) experience with twin plate clutches – so this is my problem.

Lately the car / clutch we will shudder (ALLOT) when moving away from a stand still – this is worst when doing a hill start. I also seem to get what I will describe and a groaning sound when the clutch is at the balance point. The groan will happen pretty much all the time when moving away from stand still (can replicate it) – and the noise is linked to engine speed not road speed. It seems to be coming from the passenger side front of the car – and is almost like a v-belt slipping without the squeal.

So – my assumption is that the clutch is about to go – yes ?

Having foolishly leapt to that conclusion (and I'm looking for confirmation here guys) what should I use to replace it with.

I know I can recondition the current twin plate – any suggestions on how much that should cost. The clutch was in the car when I got it – so I do not know exactly what sort of clutch it is.

What if I wanted to swap over to a single plate clutch – I understand that these types of clutches can easily take the power – but will I need to replace my fly wheel too. Will that be a better option. My current twin plate is OK (not too heavy) – but it's less than ideal for day to day driving.

Lastly – how much, or how many hours should it take a reasonable mechanic to swap the clutch out ?

all comments / advice and general sledging welcomed at this stage

it shouldn't take more than about 4 hours. my mate is a mechanic and it took him 65 mins to get an r33 gts-t box out and get the clutch off. i imagine that a gtr would take a little longer. so i'd say 2 hours each way (4 hours total) would be a safe guess.

Give the guys at Direct Clutch a call. They can recondition any twin plate I've ever sent to them and a lot better price than replacing it. As for fitting it, I'm not sure if they do that as well, there will be plenty of guys on here that can help.

thanks for that

Also

I forgot to mention that I still don't seem to get any slip - I can easily break traction - even in 3rd @ speed (I just love telling people that )

So - am I on the right track - or not ?

will a twin plate slip - or just die ?

sometimes the pressure plate will start to die, then you will get slip then eventually nothing. if it's not slipping when loaded up in 4th and 5th then i wouldnt worry about replacing it just yet.

The shuddering indicates the clutch is fine its just being driven wrong. Dont ride it so much and let it out quicker otherwise it will do as you have said (and stuff the clutch fairly quickly).

Some twin plates are nice to drive, others (like the HKS one in my car) can be down right bastards. Just give it some more practice and let it out quicker rather than hold onto it at grabbing point which is whats happening.

The shuddering indicates the clutch is fine and grabbing as it should, youre just riding it too much. Keep driving it like this and it will be stuffed fairly quickly.

Let the clutch out quicker... some twin plates are friendly, others (like my HKS one) are really bad and you have basically two options which is to stall it or wheel spin it (although I did find a point where it would start moving nicely and then just let the clutch fully go and it would be ok).

I know what you mean - mine is clearly binary (on or off) - problem is that I have had the car for almost 2 years now - and it's only started doing this in the past month or so. I don't think I've changed my driving style in that time

I've been looking at some pics and visually speaking it looks like an OS Giken (spelling ??). By that I mean it's not purple or anything

I'm as concerned about the groan as I am about the shudder

any chance I could have some oil on the clutch plate or fly wheel ?

what else could make this noise ?

[mad082]

the exeddy clutches don't stay purple for that long.

have you given the car a bit of a raping just before it started playing up? you could've damaged/cooked the flywheel or plates. it might just need machining.

and the rattle just sounds like a throwout bearing being dry. i have a dry input bearing, and it makes the oposite noise - rattles when clutch is out, not in.

simple. just give it sevan grand and dump it.

if it slips-replace it

if it lights up all 4 then happy days
