Hi all

As the title suggests, my clutch recently decided that it was bored and decided that it needed a holiday. So since it is now useless I have to spend money I don't have replacing it.

Rather than spend good money on some rip off job from a mechanic, I plan to attempt to replace it myself. (hopefully it will go better than last time, Dad dropped the gearbox out of a challenger on his hand:oops:)

Has anyone had any experience with changing the clutch, and are they able to please post any hints, tips, tricks or pics that will hopefully make the experience a whole lot easier?

Thanks alot guys

Cheers!

Hi,
After doing full auto to 5 speed conversion last year on my TB-42 GQ wagon, on a hoist I would be pulling motor out to change clutch. I had a real pr*ck off a time getting g-box in past trans tunnel. So when the time comes for me to do the clutch in mine I will be pulling motor out. That way dont need a hoist and g-box jack, only need an engine crane, other advantage to pulling motor out is that you can check/ replace all welch plugs, fix any oil leaks you may have and give motor a good clean down, and maybe even a nice new coat of paint. Thats my thought, I may get some saying that this is the hard way of doing it, but thats the way I will do it.

I think it would be easier to remove the engine and do it that wayl.
unless you have a hoist etc.
Like above machine flywheel also have the clutch fork welded and resurfaced checked for cracks they wear where it pushes on the bearing carrier.
And have the beairing carrier surface machined as well as they wear.

Just wondering what suggestions for clutch kits ppl have?
I'm going to be doing a engine change latter on down the track so thought i might as well do a clutch change as well as im not to sure of the history of it

I have done it on the floor with a trolley jack. I removed the transfer case( this is a little awkward bit makes removing gearbox easier) once the box was out i "massaged" the spot in the trans tunnel (where the starter mounts) to make install easier. I did this in a day with a mate with all the new gear there ready to go. If you can get a hoist and trans jack that would be the way to go. Have you tried slacks creek brake and clutch they are really well priced and do a superb job?

fairly easy if you have 2in body lift more clearance ! (yes trans tunnel does need a small mod )

Ive done 3 clutch changes on my GQ and the best way IS to pull the motor out 2.5-3 hrs the motor is sitting on the shed floor.
It is only a case of pull the radiator out,all the electrics are plugs except for the Alt,undo exhaust remove starter motor,undo bellhousing and its out.
No heavy lifting or risk of personal injury, heaps easier.
Also makes it easier with aglinment of the clutch plate.

You make it sound so easy chester lol you got any extra tips with the removal of the motor?
Also with so many clutches do you have a sugguestion as to a good one to use?

It's not that hard really,undo the air con compresor from the motor it should sit of to the side nicely and the same with the power steering pump.
On the bottom of the fan shourd there is a small section that unclips,it should lift up and out that makes it easier to get the fan off.
As for clutches it depends on your budget,mines a petrol so i used a heavy duty standard diesel one,i was told they are better than the heavy duty petrol clutch so far so good.
The exedy safari tuff clutch is a good clutch that can take a flogging,mate put one in his GU and i was very surprized at the hiding it took,they are fairly costly though.

Well, ended up being able to get a few more trolley jacks so haave changed it myself. Tips for anyone else doing it.

Remove the exhaust sections that run past the gear box. more room on the side.

REMOVE THE FRONT SWAYBAR!!! about an inch less you have to pull the box back before dropping it down.

If you have enough extention bars, and can get someone to guide the socket for you, you can accsess the 2 top bolts on the bellhousing through the hole in the floor created when you removed your gear sticks.

Make sure all the bolts are undone before you start to try and move the box.:1087:

Have someone to help you who works for free (e.g. your dad)

If you're able, turn up a clutch aligning shaft to help with the alignment of the clutch.

And hope you get as good k's as I did, 309000 and we're pretty sure it's the original clutch unless someone replaced it with a genuine Nissan one. (but why, I called up and they wanted $800 for the kit)

Hope this helps

Cheers!

Good stuff thats how i accessed my top bolts. It definitely makes life a lot easier having a body lift. I used a M16 bolt ground the head down slightly and works a treat to align the clutch .
