OH NOH.............hmmm,
doing a rebuild and thought it would be a good idea....current bearing feels thight though. cannot find a bearing on the market except the super expenstaimune one from LN.

WELL - on the spain site there is a guy who did a "home job"

A bearing shop can help with getting "a bearing" but without the research its just a bearing. That said if you provide the current bearing number they should be able to get a replacement... I have used bearing shops for many other cars and had great success (then again the bearing I have replaced were easy to replace and did not hold a $15k hammer over my head)

You can always give it a shot - I use US Bearings and Drives & Brown's Bearing - google them

for me, the LNE part is a great choice and since they also have the "better" bolt AND the new flange and it all works together, its a no brainer.... but...............

I do have my own machining center, however, I agree that sourcing this bearing isn't really worth the trouble. I have many engine projects and no time to waste. I will do the LN thing. Between the 996 gearbox's we service and the 996 engine debacle, the factory sure has hammered us with little or no help on purpose-they really suck!

Porsche has no part number for the bearing, they will tell you and maintain that the bearing is not serviceable.

LN and I have worked on perfecting the replacement bearing, extraction procedures and tooling for the past 5 years, lots of time has gone into the development. When you buy this bearing the purchase is for much more than just the bearing unit.

Porsche holds the proprietary on all absolute replacement bearings for this application- Its not as simple as just picking up the phone and ordering a bearing. Most bearings that are sized the same as the IMS bearing are designed for inner race rotation, where in this application the outer race is the rotational component. This complicates things greatly and one would see very early on just how critical bearing design and application really are.

Its very odd for a bearing like this to have the inner race parked and the outer race in rotation.

I would just buy the kit. why?
1. the flange has a better seal and a little different design. I assume to let more oil in to the bearing. Plus I am a fan of supporting the support. I am sure they have bookoo time invested. And really, is it REALLY that much money? we are talking about a Porsche not a 350 chebby.

Although i HAVE had my fare share of head butting with Jake. They deserve the sale.

Here was my thought on going at it alone with pulling the bearing and finding one to match on my own...
Ok they fail anywhere from 5K miles to whenever??? Yours has ran for XX time THIS TIME. But you are disturbing EVERYTHING. You put a stock bearing back in with the stock flange.... its my opinion you set yoru self up for failure. Being we really don't know WHY they are failing.

Could it have been the way the bearing was broke-in the first 1000 miles?
Could it be the way the car was driven for the first 3000 miles?
Did someone dump some magic additive in the oil that saved it?

With LNE or F6I they made some changes to keep the bearing more oiled and put in a bearing that is meant to be oiled with the oil the weight of engine oil.... I think your trying to save a few bucks is plane sillyness.

Jake Raby

The flange in the factory arrangement is less substantial, which is why we made the billet flange. Over time Porsche has changed the flange and made is stronger as well as adding more sealing surface, so they recognized part of the issue.

Certainly do as you wish, but you'll end up spending more money to do this job without the kit than you will with the kit IF you outfit the engine with the same quality (silicon nitride) bearing and the same flange strength.

I was just down talking with my indy, he was in Jakes motor rebuild class just a couple weeks ago. On the table - a motor torn down with an IMS disaster. What a mess! I held the parts in my hand and shook my head, then told my indy there should be a line of cars waiting for this retrofit. The OEM bearing has a life expectancy that is pretty short!

I will be ordering my kit soon. Praying in the meantime!

ivangene

OH also saw LM's new block on the table, new thermostat and I really like that block! (Just opened the crate!)

After doing the retrofit, you should follow Raby's advises like extreme the protection with better oil engine, better oil filter, and so on

I spoke with my indy yesterday and he mentioned he had also just returned from the same M96 rebuild class. From what he understood the IMS bearing replacement would be considered a regular long-term maintenance item, even after the new bearing is installed.

ivangene

Jake - can you confirm that? And give life expectancy rating for the new bearings?
