Clutch change: What else is changed at same time ?

[michelin]

Curious really. I realise the actual clutch will be changed, just starting to slip now so I have caught it early, but what else? Gearbox oil ?? Other bits ??

[phillipj]

You don't need to change the gear oil until 80,000 to 100,000 milies. Just make sure your flywheel is still in good shape and replace the release bearing as well. Stay with the OEM cklutch kit. You didn't say how many miles you have on your car so this is general info..

:cheers:

Hi

Car has 36k on it. I thought the gearbox oil would have been drained off to access the transmission?

As I say I have little knowledge in this area.

Thanks for any help.

Good time to update the RMS and IMS; due to how difficult they can be to get at, I'd also do the AoS while the car is apart.

Hi

What is the IMS and AoS?

The IMS is short for Intermediate Shaft. There is an upgrade by LN Engineering that is recommended especially if you already have the majority of labor done to replace the clutch.

MORE info HERE on upgrade.

The AOS is short for Air Oil Seperator that is very difficult to replace with the tranny installed (not impossible, just difficult) It frequently fails and needs replacement from time to time. Very easy to do again once tranny is out. Press HERE for more information from Mike Focke's website.

You also may want to check your oil filler tubes for all the same reasons as stated above.

Liverpool my friend :thumbup:

JFP,

The member (Michelin) didn't state what year his car was.. If it is an 06 or newer why would he have to upgrade the IMS? Didn't Porsche already do that (upgrade the IMS) in the 06 through 09 models?

We may have been neighbors at one time, I lived near Runcorn (across the A533 bridge below Widnes), as well as down in Dorset and in the Isle of Man. Small world...................

His profile does not list the year of his 911. Unfortunately, if he does have an 06 or later car, he still faces the risk of engine failure due to the IMS (yes, even though the engine would have Porsche’s “final solution” for the IMS problem, this last version still do fail), but unfortunately he cannot easily upgrade it because it would be the large diameter IMS which cannot be replaced without total disassembly of the engine. LN Engineering does have an upgrade for this version of the M96/97 IMS, but for obvious reasons there are not that many being upgraded…………..

Hi guys

My car is a September 2006.

The car is in the workshop now and the technicians are going to check both RMS & IMS.

Fingers crossed all will be ok.

LN Engineering along with Flat 6 Innovations have developed a process and tool which allows you to replace the larger IMS without having to dismantel the engine. LN Engineering explains the process on their web site and go into great detail on the causes of IMS bearing failure and how to recognize it. Interesting read.

I think you need to re-read the LN website concerning the late 05 through 08 IMS units; the late 05 and on cars (or factory replacement engines) all carry an oversized rear bearing that cannot physically fit through the opening in the assembled engines:

" If the engine was made for MY06 or later, it will have the late revision, larger IMS bearing which is not serviceable."

"The last option, our IMS Upgrade,

requires engine disassembly.

The intermediate shaft must be sent in to us to be upgraded to our triple-bearing upgrade. A separate ceramic hybrid bearing upgrade is available for the late-style MY06-08 M97 IMS as well."'

JFP,

Thanks for the great info..

Well finally got her back last Friday, £1100 lighter !. Good job done though.

All the things you guys mentioned were checked and are fine. Thanks for all who contributed.

Next up is replacing the engine emblem with the '911' badge !

I've already posted up a question on best practice.

:thankyou:
