G'day all,
I have a 1998 GU Patrol with the 2.8 TDI engine. I'm putting a new clutch in and it needs a new flywheel, as it has the dual mass flywheel similar to the ZD 30 engine which are non machineable. I'm interested in fitting a solid flywheel and H/Dclutch from Exedy, who are the OEM manufacturers for the original dual mass flywheel, but what I want to know is -
1 Has anyone else replaced their flywheel/clutch with a solid type and if so are there any problems to watch out for;
2. Does any other clutch supplier offer the solid flywheel/clutch as a kit;
3. Why do all the new car manufacturers seem to be fitting these dual mass flywheels when there doesn't appear to be any advantages to them?
Thanks, mer4wd

A bloke I know who is a mech. has a 2.8 also and had a vibration that went away when he changed to the solid flywheel. He's very happy to say the least and wouldn't hesitate in recommending one. I will go the same way also when
mine needs replacing also.

Thanks Leroy - another quick question - what's the fuel economy of your 2.8 like?

previous owner of my 2.8 gu replaced the clutch about 15000 km before he sold it, he put a new duel mass in it so I would love to hear of your exp with a solid flywheel if you go that way.

I have a 1998 2.8 patrol - fuel economy over the past 225000km has been an average 12.33 ltrs/100km. Recently I've bought an off road campertrailer (1.4 tonnes laden with boat on top) fuel consumption rises to 14.5 - 17 ltrs/100km depending on wind conditions. I haven't bothered to calculate what it uses in low range or sand or........

Pete - thanks for that
feedback, I thought I should be getting better out of my 2.8 -I'm only getting 14l/100 around town and 13 lt/100 on the highway, my '98 GU has only 145,000km on it and has had the pump and injectors done recently. Admittedly I'm running 285/75 R 16 X Terrains which causes aslight loss, but still should get better than what I'm getting.

Gday Pete and Mer
Just to ad to the whole fuel economy thing, I generaly get around the 15 - 16l per 100km, highway driving at around the 110kph mark, would love to be getting your figures. Just recently had lpg fitted, and has been a good improvement in power (14%), and economy has remained similar litres(combined) per hundred. Just after the lpg fitting it has started blowing bubbles in the coolant - hoping its just a head gasket & not a crack...while its pulled apart I'm getting the injectors and Pump overhauled.
I haven't had such a good run with this engine, so this is the last time it gets major work from my wallet. if it plays up again it will be either sold as is, or get a 4.2 or 6.5 transplant!
Cheers Andrew

G'day Andrew,
After hearing your side of things I shouldn't complain about economy - doing pump and injectors and head on yours might help, but you'd think the LPG would improve things a bit. Be prepared to be stung for your pump and injector overhaul though - it cost me 3 grand, but I've since learnt that the
shop that did the work has a reputation for being pricey, but they appear to have done a good job.

Gees I must be lucky or something...I've only ever done the regular servicing (plus oil and filter at 5K intervals) and I had the injectors overhauled at 200000km just because it was that many Km's not because the engine was playing up. I intend doing a West to East crossing throught he centre in 2009 and if I still have the vehicle will probably change the clutch and flywheel (exeddy solid). BTW the injector overhaul only cost me $700 so thought that wasn't too bad - reputable company too Queanbeyan Diesel.
Cheers

Gdy Mer and Pete, the Lpg did basically what I expected - instead of 15l of diesel I use 11 litres of diesel and 4 litres of gas, but i haven't been able to give it a good testdue to the head etc..............I've had a bad run with this engine, had virtually every problem they can, cracked head, rebuild due to overheat (i have a low coolant alarm now), and it has never been as economical as anyone elses I know, so I hope the Pump/injectors sort it out, otherwise the expensive options come out....mmmmmPezza if your reading, that 4.2 looks alright......same colour and all!
Cheers Andrew

I asked one of the clutch specialasts that had a stand at last years
Sydney 4X4 show, about machining these flywheels. He said that a good clutch specialist can machine them. Unfortunately I can't remember which company it was. If you make some enquiries with some of the major clutch specialists, you should be able to find someone who can do it.

G'Day mer4wd,
This is my experience only
"1 Has anyone else replaced their flywheel/clutch with a solid type and if so are there any problems to watch out for"
The cost! Was quoted around $900 for a solid flywheel only.
"2. Does any other clutch supplier offer the solid flywheel/clutch as a kit;"
Exeddy make the OEM one and two versions aftermarket, one called normal duty and one heavy duty, the only difference is the size of
the springs on the heavy duty, the clutch plates themselves are the same.
"3. Why do all the new car manufacturers seem to be fitting these dual mass flywheels when there doesn't appear to be any advantages to them?"
Based on the theory, they smooth out driveline vibrations, meaning that you can get lower NVH, (Noise, Vibration, Harshness), levels without going to the expense of manufacturing the driveline to tighter tolerances.
If the thought of spending $2000 fitted for a new flywheel / clutch does not concern you then by all means go for it. For me it was excessive without concrete evidence that I was going to get value.
I changed the clutch only to an Exeddy heavy duty, without machining the flywheel, after some long discussions why my mechanic.
Very happy, nothing negative to speak of and all up cost around $800 including the clutch kit. Has been in for almost 30,000K's now
Regards
Rolande

thanks Rolande,
The clutch I'm getting is the Exedy H/D one, with a solid flywheel included for about $1100 which I'm fitting myself so sounds like I'm getting a good deal. I can't find anyone else who supplies a kit like this, so that's why I was a little wary. Thanks for your
feedback.
