GQ Manual Issue - Possible Clutch Issue?

[Jimmyboyjr4]

Hi all,

I've been finding recently that when I put my GQ into certain gears and then try and accelerate the rev counter will climb 500-1000rpm and then drop down to normal and remain consistent with my driving. This all happens without moving my foot on the accelerator at all.

Is this what happens when your clutch starts to go?

[Jimmyboyjr4]

I've read some advice around the net that sounds similar to my problem but a multitude of answer, safe to say that I'm confused haha

i could guess all day but until i drive it couldn't say for sure.

easy way to check if your clutch is shot,with handbrake firmly applied hold the revs at about 1000-1200 rpm select 4th gear and release clutch, engine should stall instantly, if it gradually slows to a stop or manages to keep running your clutch is stuffed, just bear in mind this test is hard on the clutch so dont go doing it every week just to check

[Jimmyboyjr4]

Oh thats a good one, I've give it a go.

Worried it's something worse but hopefully just the clutch.

[Jimmyboyjr4]

So it turns out the clutch is definitely starting to go.

I guess the next question is which clutch is best for replacement?

[Jimmyboyjr4]

Am looking between an Exedy Safari Tuff or Exedy heavy duty clutches.

Any one have any insights on whether these are any good? Or what the difference is between them?

[garett]

exedy heavy duty refers to a stronger spring than the standard clutch kit but the same friction plate. no idea what the safari bit is. only seen one exedy fail prematurely was in a poosar.

[Jimmyboyjr4]

In what circumstances are heavy duty clutches recommended? I have no idea about clutches!

Just wondering if there's any point for me over an OEM clutch

[garett]

from what i can read on exedy's web site the safari has a heavy duty spring with a different friction plate that is suppose to last longer.

the heavy duty is for engines with a bit more torque so it won't slip as much.. as i still have the original clutch with over half a mill k's ... and never had it slip. now if you were to put a turbo on it that would bump up the power and i got no idea what clutch would be the right one. some one who has a turbo would be better to answer that.

Exedy have a rep for being good clutches can't see either being a bad choice for a pretty standard car. even the oem replacement from exedy should be fine for a standard car (just be gentle with your clutch and it will last, goes for all clutches)

[Jimmyboyjr4]

Appreciate your input mate, I am thinking of heavy duty as I would like to get a turbo on the GQ in the next few years.

Do you know how, or if, this affects the vacuum assistance?

Sorry to bombard you with questions but am trying to learn as much as I can!

[garett]

it may make the pedal feel a bit heavier. i don't have any vacuum assist on my clutch (td42) and its not that heavy.
put a heavy duty one in a gu tb48 with vacuum assist and it felt fine. i doubt it would be a problem.
