United Kingdom 2015 Defender 90 Puma 2.2 SW Corris Grey
2015 90. Purchased from new, with original clutch and output shaft.

Now just over 60k miles the clutch springs are starting to rattle along with some juddering when cold
But appeared to be ok when it’s warm!

T/Box and gearbox now out for a refresh of clutch and output shaft.

All the springs are loose but the friction plate appears to have a lot of life left in it.

There was a lot of dust or more than I expected in the assembly.

One question
Do I replace the crankshaft oil seal as it appears to be fine and I’m only on 60k??

2009 110 USW- circa 40K, clutch went on the M1

Replaced the whole shebang, clutch, slave and master (replaced the master first and that didn't fix it, so whilst the gearbox was out replaced clutch and slave)

Got an indy to do the clutch and slave

Def90 - Just to clarify that’s a genuine clutch?

Kmac - Which clutch was it, if you happen to know? ⭐️⭐️God Bless the USA 🇬🇧🇺🇸 ⭐️⭐️

Mine on my TD5 lasted 22 years 120K. It didn't fail and was replaced when i had the Alive work done to cope with the increased power.

Definitely the original factory clutch , had the 90 from new and it the first time the gearbox has been off.

Interestingly if you look at the picture of the friction plate it has a Ford part number!

Have all new replacement parts with a Sachs Transit 4x4 clutch to fit.

I’m just not sure if I should change the rear crankshaft oil seal as it’s in good condition with no sign of leaks.

I have had 2 standard clutches both rattled badly but operated just fine and when removed had loose but not fallen out springs, currently have a LOF clutch which so far has lasted twice as long as the originals DEFENDER 90 TDCI XS,

I hope everyone is well and your land rovers make you happy

A difficult choice, since many replacements immediately leak especially if not fitted correctly. Your seal will leak one day, mine started at about 200k miles and has been leaking slightly ever since. I will replace it when I next replace the clutch (which is now way overdue). It wasn't leaking when I last replaced the clutch (which was around 150k miles) because I would have replaced it then if it had been.

I think I would leave it if it is not actually leaking, unless you have a significant mileage on the vehicle (say 150k or more).

Incidentally for those who are interested in these things, my current clutch (genuine LR) has now done around 120k miles, which is significantly more than any previous clutch (it's something like the 5th clutch the vehicle has had since leaving the factory). LR clutches have undoubtedly improved.

I did post on another thread about my clutch failure.. But at the risk of boring folk and in the interests of this thread which is attempting to pool the information I'll add it here as well..
2014 2.2l tdci 110..owned for a couple years and clutch was original..
Failed at 47000miles.. And on removal the springs in the friction plate were the issue.. Had been making contact with the diaphragm springs fingers and damaged the spring housing on one spring..

Replaced with a LOF clutch kit.

I replaced the rear crankshaft oil seal at the same time and regretted it.. It leaked immediately and the job had to be done again😩

Andy63 - That’s pretty much the same issue I had with mine.

Yes, the LR clutches has improved but look at the time in which it has taken them.
Perhaps they don’t handle the slightly increased HP too well?

Regards the crankshaft oil seal, from what I can see it appears that they are best left alone unless they leak.
If they leak, then replace but if not leave them alone or they could start leaking. Laughing
If it isn’t broke, don’t fix it.
The SMF seems best left as well, unless there is an issue with it.

Rattling springs, or springs came out seem far more common that a worn out clutch.
Most friction plates seem to have a lot of life still left it them, and the springs issues cut the clutch life down considerably.
Master cylinders seem to have a very long life, and TD5 or earlier clutches seem to have a longer life than Pumas perhaps due to improvements made over a long term or transmission difference. ⭐️⭐️God Bless the USA 🇬🇧🇺🇸 ⭐️⭐️

Yes Steve, when I was looking through the thread and saw your pictures I thought I was looking at my friction plate👍😂..
Whatever thread it was I originally posted in, saying I couldn't believe that the diaphragm fingers could contact the plate springs, it was black wolf who pointed out it was indeed a common fault.. 😳

Hi

Thank you for your replies and advice re the rear crankshaft
Oil seal, which I think I will leave alone for the time being and
just wait for it to leak.
