Another IMS Solution?

[Jake Raby]

The 3 failures have all been single rows..
-One of them suffered damage from a tensioner paddle failure that contaminated the bearing with foreign object debris.. The bearing will not live through this, don't even expect it to.

-Another of them suffered a failure where **possibly** the installer did not get the snap ring seated correctly. I did the post-mortem on this engine and the actual means of failure were not conclusive, so LN did the right thing and warranted the bearing and I reassembled the engine. (This was not my engine or install, LN paid me to evaluate and repair the engine).. The owner of the car didn't have to ASK to receive this level of service.

-The third failure appears to have been a classic bearing failure; nothing was present to suggest otherwise.

NONE of the bearings we have installed via retrofit or full (triple row) upgrade have failed. No dual row retrofit bearings have failed. Out of 4,000 installs 3 failures have occurred, one of which was DEFINITELY related to foreign object debris collateral damage, another of which may have been.. That leaves one out of 4,000 that simply grenaded..
