2000 Tiptronic Cab IMS Bearing and other maintenance item questions....

[Johnny-5]

So I'm currently debating if I want to do this myself or if I should get a shop to do this. I'm mechanically inclined to a certain degree but something about Porsche's scare me. Possible how cramped the engine compartment is??? Who knows! I've read here and there how painful the process is and wanted to get some feed back on the process. I'm sure if I take it in I'm going to get reamed on price that's for sure. Any feedback would be greatly appreciated.

 

Now my other question I had...While were at it is there anything else that should be done? Is it easier getting to the AOS with the transmission removed? I dont have any current issues with it but you never know and while were at it I figured I get that over and done with as well.

 

Thanks in advance!

I've done a lot of work on cars way back when, and I do most of the work on my 986, but I had the IMS done by an independent shop. The labor was about 2-1/2 to 3 times the amount of what the tools would've cost. For this operation having a warranty was a major deciding factor, especially when weighed against the possible savings available.

 

The "might as wells" included the AOS, RMS, and Trans Fluid/Filter.

 

Also, when a LN Engineering approved shop does the work, they check first to see if the engine is "qualified" for a Retrofit bearing, thus securing the warranty.

 

Lastly, the bearing choices from LN at the time I had mine done were the Single Row Retrofit or the IMS Solution, and I went with the Retrofit since it was about $1,000 less. Anything other than a plain bearing is a maintenance part - it'll need to be done again in the future. Knowing what I know now, I would've gone with the Solution.

I agree 100%, go with the ONLY US patented IMS bearing that will last longer than the life of most of the components on the M96 engine - The IMS Solution!

Thank you for the recommendations. I'm tempted to try this myself but like you I may just go with a shop.

So I got a question before LN Engineering was the way to go but there seems to be another company I heard nothing but good things on which is EPS which utilizes a cylindrical bearing design which also claims the life of the engine. Anyone tried that company?

I have no dog in this fight. I'm not going to risk my $20K+ motor on a roller or ball bearing design, IMHO. Everything I've read over the years shows risks from radial load on roller bearings which potentially could lead to failure, but I guess the cylindrical roller bearing is their "solution"? Problems associated with ball bearings is why we're in the this mess in the first place. I believe the IMS solution by LN with it's oil fed plain bearing design is the best technology out there. Why do you think the Mezger engines are so valuable to racing?... one of the reasons is because of it's durability on the track. Those Mezger engines use a plain bearing design on their shafts.

Sorry for the delay. Thank you for the feedback and valid point.

Doing it yourself will save a ton of money. Get the "Solution" you can do it  in a weekend. Most of the time consuming things are simple...
