Thread: Dual mass fly wheel specs

Out of interest, why is it on the bench? Clutch swap, or something else?

Before it came out was there any excessive rattle or juddering on clutch take up?

If the at has had a relitavely easy life (not always fully loaded an heavy towing), if it's reformat clutch change is guess it'll be ok. Rattle and juddering are key things to look for when it's in the car. On the bench, there shouldnt be much slop between the two halves.

If its knackered and depending on what the car does everyday it may be
Worthwhile changing the DMF for a solid hobby and appropriate clutch plate from Rakeway in the UK.

Big cost difference between a regular clutch plate an a new flywheel as updated clutch though

Just replacing the clutch, it was slipping but has had a pretty easy existence. The plate is barley worn, machine marks on the pressure plate and fly wheel still 'crisp'. The spring on the pressure plate feels pretty much like the new one. ??? Some glazing is evident on the clutch plate but that is expected from the slippage. I thought that diesel from the leaking regulator may have been the cause, but it wasn't exactly wet with it inside the bell housing. I was really quite surprised at the size of the clutch (or lack there of).

The main reason for having the fly wheel out is to replace the rear main seal, which I thought would be a smart move but will take advice.

It doesnt take much for them to start slipping and there's not often any sign of significant wear. The size of the clutch plate is a legacy from when they produced about 1/4 of 1bhp - they are not really big enough for TD5 engines and are now constrained by the physical dimensions of the DMFand bell-housing. To get bigger you need to loose the DMF, but thats another story.

From what you say I'd replace the main seal (now that you have access to it) and release bearing (and possibly plastic assembly/ carrier).

Id suggest that second to the clutch plate, the most problematic bit is the release bearing and assembly.

I would re-use the DMF, replace knackered clutch plate with a new OEM one (Valeo if memory serves right).

I play around with clutches all the time dmf flywheels go in the bin when it's clutch change time regardless of brand or how hard they have worked. Why do the job twice

Thats exactly my thought too, can't abide the thought of doing all this again.
If only I could get my hands on the neck of a Landrover design engineer!

Maybe there never was one.
