Engine: LN engineering IMS Single Row Intermediate Shaft Bearing Retrofit Kit 106-08.2.2 for Porsche 996, 986 Boxster and early 997 and 987 models

As of 2020, with 35.000 IMS Retrofit and 3000 IMS Solutions installed since 2008, our IMS bearing replacements are the most trusted and used by hundreds of independent mechanics and dealers around the world.

WHY DOES THE ORIGINAL IMS BEARING FAIL?
Lack of lubrication because a sealed bearing was used at the factory. The IMS is submerged in engine oil, so removing the grease seal ensures proper lubrication of the new bearing. No forced oil is needed!
Insufficient load capacity. The factory single row bearing had a high failure rate of 8% according to the Eisen class action lawsuit compared to the 1% failure rate of the factory double row bearing under warranty.
The factory has not provided a service interval, replacement, or tools and procedure for replacing the original bearing. The original bearing should have been serviced!
The Single Row Pro has a service interval of 6 years or 75.000 miles, whichever comes first.

IMS RETROFIT INTERMEDIATE SHAFT BEARING AS PREVENTIVE MAINTENANCE:
IMS replacement takes an average of 10-14 hours and requires the transmission to be removed. For the Titronic 911 models, the engine and transmission must be removed as a complete unit in order to separate the engine and transmission.
Usually associated with clutch and other maintenance such as replacement of RMS, AOS, water pump, dual mass flywheel, etc.
If an engine failure occurs, rebuilding takes more than 60 hours and can cost tens of thousands of dollars to fix. Once the IMS bearing begins to fail, it cannot be safely replaced, as worn metal from the original bearing can damage the replacement bearing or other internal engine components.
Motors must be pre-qualified before replacing bearings. For more information about prequalification, visit https://lnengineering.com/products/ims-bearing-installation-tools/ims-pre-qualification.html

HOW IS THE ERROR-FREE IMS TOOL USED TO INSTALL THE SINGLE-ROW PRO INTERMEDIATE BEARING AND THE INTERNAL THREAD LOCK?

In this video Jake Raby shows how to install the Single Row Pro IMS bearing. This bearing is held using an internal thread lock such as the factory double row, so a specialized tool and procedure are required to install the bearing and thread lock at the same time.

WHICH FACTORY BEARING DOES MY ENGINE HAVE?

• 1997-1999: This engine had an IMS with two rows of bearings.
• 2000-2001: These motors came from the factory with either double row or single row IMS bearings. A single row flange is 19,27 mm deep and a double row flange is 13,34 mm deep.
• 2002-2005: This engine had a single row IMS bearing. Some late production 2005 models have a non-serviceable IMS.
• 2006-2008: These engines are fitted with a larger bearing, easily identified by the 22mm center nut, which cannot be serviced without completely disassembling the engine. Removing the IMS bearing grease seal ensures proper lubrication of the original bearing.
• If the engine in your car was replaced, it will have the IMS bearing that was in production for that model year of manufacture for the replacement engine.
