Hydraulic Clutch questions - GEN4 Liberty

SUBYDAZZ · Post by **SUBYDAZZ** » Sat Oct 22, 2011 8:12 am

I'm currently shopping to replace my written off Liberty and test drove a 2006 GEN4 Liberty yesterday but it had significant clutch issues (that the current owner wasn't aware of?).

It's basically slipping under load so the revs rise higher than the road speed at times and then it catches back up. The biting point is right at the very beginning of pedal, so my question is: What does that mean? Worn out clutch or out of adjustment? Can you even adjust the hydraulic clutch other than at the pedal? If you can adjust it at the pedal does that mean that the pushrod for the master cylinder must be wound or adjusted all the way out?

Fluid level seemed OK.

the adjustment at the pedal is minimal and normally just to get pedal play/throw correct. once a hydrualic clutch starts to slip it is normally time to replace it and the silly dual mass flywheel behind it

Subaru sell a dual mass flywheel replacement clutch kit for around $1000

I had this really badly with my stock clutch 4months ago. I ended up gettign a whole new clutch kit. Mine was really bad though, I could barely get up small hills. It actually died offroad near Bunbury, W.A and I had to drive about 150km back to where I was staying :P
I also have both master and slave cylinders replaced due to the clutch sticking to the floor and not coming back up.

So which models had the dual-mass flywheel or whatever that seems to be not a very good thing?

I just replaced my DMF and clutch in the Forester (187,000 odd Kms), the take up point (bite point) on mine was also high, now it's closer to the floor and a lot lighter.
I did have a DMF kit fitted by City Subaru Brisbane at 74,000 odd Kms, upon reflection I feel they just added heavier springs to the clutch to stop/reduce the rattle.

The new clutch and flywheel seems to have increased the torque and the acceleration as it feels easier to accelerate at 110 Km/h than before and it climbs that hill on entry to and from Caloundra a helluva lot easier too, at the moment I am loving the change.

Does $1136.38 with GST sound right Frog?

It's not a DMF, the mechanic said it was now a solid flywheel.

Don't replace the DMF, get a solid flywheel from an EJ22 and matching clutch kit.

EJ22 clutch kit is about $300.

Scrounge a flywheel from a wreckers or someones conversion left overs, get it machined and put it all together.

It's too late Jordan, the deed was done 11 days ago by Boxer Service.

So what's the advantage of this Dual Mass Flywheel everyone seems to replace with a normal one? I was even told that Subaru superseded the DMF clutch parts and replace the DMF with a SMF kit on certain models as a matter of course?

Any truth in that?

Dual Mass v Single Mass Flywheel

Ah, but I've never driven a Subaru with a solid flywheel that drives like a truck in the first place

Dual Mass Flywheels are there to reduce shock loading on the gearboxes during hard driving. I don't see it has saved many gearboxes. I'd go the solid flywheel off an early model (prior to EJ25 SHOC models), so anything up to 99 model in the Liberty/Outback platform.
