And, I find this bold type.... interesting:

"DESIGNED FOR THE LIFE OF THE ENGINE. 5 YEARS / NO MILEAGE LIMIT WARRANTY"

The IMS Solution solid bearing is designed to go the life of the engine, we have never seen or heard of one failing, or wearing out. We are aware of a couple that have been pulled out of one engine (having suffered dropped valves or rod failure) and then reinstalled in another engine where they continue to serve without problem. No other IMS retrofit can be reused.

From conversations with those more in the know, they have no designed life expectancy.

Help me understand why no other IMS retrofit could be reused. Thanks.

With a roller bearing or ball bearing, you risk damaging the races in removing the bearing. High risk. As in, it'd be REALLY hard to NOT damage it.

That makes sense, thanks.

With ball or roller bearing types, the extraction process literally jams the bearings into the race and cages, damaging both. The cages in particular tend to break up and the races get dented or scored due to the force exerted on them. Once this happens, the bearing is going to fail if reused.

Thanks! Makes sense.

This is also why retrofit kit manufacture's have always said if you get an install cocked and stuck, and have to remove it, do not then re install the retrofit bearing as it is now damaged. This was particularly an issue with single row bearings which tended to do this more often than the dual row bearings. This is one of the reasons Jake released his "Faultless" tool system, which prevents getting the bearings cocked during installs.

IMS again... or not???
My 2001 Boxter Base had IMS done 90.000mi ago (then 60.000mi on odo) with this part: 996.105.017
Can I find out from this number if the bearing is single or double row IMS?

Are these IMS bearings items that needs to get done every so often or only to replace the factory original with updated one?
If these need to be canged contionously as a service, I guess it's due in my car now...

Part is listed as a housing. with engine numbers. So I wonder if it was really a bearing change.

Part is listed as "housing". Commonly called "flange". So how do we know if a bearing was changed?
