Unfortunately in my opinion this 911 has been poorly maintained the last couple of years, the carfax shows no history of any major work being done other than the long block was replaced 2 years ago.

Since you have to wait and see which bearing is in there you can also wait to inspect clutch flywheel rms.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Getting closer to doing my IMS/RMS replacement, on 2001 996 C2 87k. The gearbox seems to shift smooth through all gears, but it�s my first pcar, so i have nothing to compare to. My question is what other maintenance items should i do while i have the gearbox dropped? Don't mind spending extra $$ and time, on the project, but at the same time I believe it�s senseless to just replace parts that appear to operating as they should, unless the cost is insignificant. But I want to get the option of all the seasoned pcar owners on here as I usually do. Thanks in advance

POST 3Original post

I'd test the AOS and check what the heat exchanger looks like. They tend to leak slowly and both would be more accessible with transmission out.

POST 4Original post

When I had the IMS done in my �02 last year the clutch, slave cylinder and AOS got done at the same time as it made sense while it was apart.

POST 5Original post

Here is a potential laundry list of additional parts to consider w/ IMSB/RMS 1. clutch & flywheel 2. trans mount 3. trans fluid 4. oil cooler 5. UAOS 6. engine mounts

POST 6Original post

Since you have to wait and see which bearing is in there you can also wait to inspect clutch flywheel rms. Then order the parts accordingly.

POST 7 / ORIGINAL POSTEROriginal post

I dont know if the clutch has ever been done, im guessing not. Unfortunately in my opinion this 911 has been poorly maintained the last couple of years, the carfax shows no history of any major work being done other than the long block was replaced 2 years ago. I was able to track the shop down that did the work and unfortunately they had no detailed records available.

I�ve tested the AOS using the technique on this forum and it checked out, but I haven�t done anything to check the heat exchanger. UAOS is on my list of items i want to change, but I don�t know if I can afford to do it at the same time

POST 10 / ORIGINAL POSTEROriginal post

Quotes source post: 20664889

The engine/transmission mounts are on my list to do at the same time. The fluid would be easy enough. But I have not thought about the oil cooler. If I was to replace the clutch and flywheel, what replacement should I be looking for stock or should I upgrade it?

The kit I�m ordering comes with both bearings and I can return the one I don�t need.

sorry, I should�ve mentioned it is leaking

POST 13Original post

If the RMS is leaking, MESS with it! :-)

POST 14Original post

New flywheel bolts. New pressure plate bolts. If you are doing the clutch, new pilot bearing.

Forgot to answer your question on the clutch and flywheel. I would go oem for both. Some guys will do a Sachs clutch for street driving. But I would stick with the oem dual mass flywheel. I run a Spec clutch and oem dmf.

POST 17 / ORIGINAL POSTEROriginal post

Quotes source post: 20665628

Thanks GC, what stage are you running? i’m assuming I would only need stage one. Should i stay away from LUK fly wheels?

POST 18Original post

Quotes source post: 20665804

My indy put on a stage 1 well over 15 years old. Its held up well with alot of track days as well as street driving. I don't know anything about the Luk fly wheels. They insisted I should use the oem flywheel. This winter I am going to have them drop the trans and go thru everything IMSB/clutch and flywheel related and see what they suggest.

POST 20 / ORIGINAL POSTEROriginal post

Quotes source post: 20666145

the price difference between Porsche and LUK may allow me to replace both components while the gear box is dropped, otherwise it will have to wait. I�m doing the work myself so not a big deal for me to have to go back later and do the clutch/fly wheel
