I have a 2008 landcruiser V8 ute and for my trade I regularly tow a heavy trailer on and off sandy job sites. Just before Xmas I could smell clutch when towing and could feel the slip when accelerating with the load on.

I booked it into a local specialist mechanic shop and asked for a heavy duty clutch replacement. Done and all was well. Until now. 6 months later and my clutch is slipping again.

The clutch I had installed as I understand was standard clutch with heavier pressure plate. It also meant the disengage was right on the floor which made it difficult to change gears.

I am now looking for another clutch ( the shop I used before has shut down - damn or I would be back there.)

Anyone know which heavier clutch I can install - where to get it from and another clutch installer around Mandurah WA.

you have been the victim of a small cap V8 putting out good KW's and torque at higher rev's with a turbo.

I have noticed the difference between the V8 diesel cruisers and my old natural 6.5 clunker. We have no problems with clutches at all because we use low range with and not towing load.

For instance I have to force myself to use 1st gear when taking off with my old clunker, it will do it easy in 2nd but this is not good for my old gearbox. Your problem is you have a great gearbox but a problem with lowdown torque.

Just drop her into low range until you are on good hard flat ground and then use high 1st, the problem will go away.

Have a good one,

I should have added when towing a van I use 1st gear.

Hi Rockape

Your advice is pretty good on here. So I think you might be the one to talk to.

What you are saying is I should be going into low range more often when pushing through some soft sand with the heavy trade trailer even though the motor will do it in high range. Too much force for the clutch to handle in high range.

Problem is the clutch smell comes now just driving home on the bitumen. Pull up at the lights and I smell clutch.

your clutch is totally stuffed and it is only a matter of time before she won't go anywhere.

I am not saying there was nothing work with the clutch originally, it may well have had a problem but no problems have shown up on any of our cruisers. The drivetrains have been excellent with no problems occurring since 2007.

I am lucky enough to drive the V8 cruisers, my old cruiser with the 6.5 chev and I also still drive an old 1hz at work + at times 2.5 nissans and hiluxes. The old 1HZ takes off just as easily as the V8 off idle it just doesn't crank up like they do.

The luxes and the nissans are the worst and have very little torque down low, they are ok if driven empty but once you put a load on them you have to be careful with the clutches. The V8 with a load is nowhere near as bad as they are but once loaded the initial take off requires more revs to get them going which also means a bit of clutch slip. As said with my van on the back I always use 1st gear and minimum revs, I believe when you get the clutch replaced which they may do under warranty, you would be better off engaging low range second until you get to good ground and then go into high range 1st, there would be no need to put the hubs in.

Couple of thinks that also will cause it is the throwout bearing being adjusted wrongly or the old foot resting on the clutch which I doubt you do.

Have a good one

Since having the clutch replaced just before Xmas the throw out bearing has made a noise - like the bearing was worn out or loose. I read up and this can happen when a reconditioned pressure plate is installed that has bearing marks on the fingers.

The other issue after install was I could not engage and disengage as the the pedal needed to pushed hard into the carpet. When at the installer booking it in I overheard him talking to the supplier who said the heavier pressure plate required a longer pushrod on the slave cylinder attached to the bell housing. Not sure whether he installed this. To overcome the gear changing issue I adjusted the clutch foot pedal up a bit - not enough to my liking but just enough so I could reasonably change gears. Still had a few missed gears.

As I said I tried to go back to the installers whom I would say are reputable but they have closed down after years and I heard they are looking for new premises to start up again. Not sure why.

Now I am faced with either finding a new installer or doing it myself. I have done a few clutches before but they are heavy difficult work. And which clutch to install that will cope with the constant heavy towing load I put on the ute. I suspect there might have been a small issue with the install as to why the clutch has given out after only 6 months.



PS I will look up the 4terrain clutches, Exedy clutches, and Centerforce clutches. No online prices so far.

Get yourself a 4Terrain semi button clutch. Mine in my Patrol has done 230,000 k

I phoned these guys but they have not developed a clutch for my vehicle as of yet - the guy said the computer shows 'under development'.

Gday David,
I'm pessimistic about the original work. If you clutch smells after a highway run, then it is slipping. You need to start again. Was the flywheel machined? What clutch was fitted? The fact that you have the bearing noise either means the old diaphragm spring is in there or the bearing wasn't replaced or they didn't put a smear of grease on the bearing face.

Can I suggest you phone an Adelaide company about your problem and see what they suggest:
These guys have known everything about Landcruiser clutches for many years.

G/Day Mate, All of what RockApe says, And also if the master cyl adjustment is wrong eg( No Free play), then that will put pressure to the slave cyl so over a short period the clutch is getting slight pressure allowing it to slip.
