Bentley Publishers has produced an excellent video on the IMS Retrofit procedure using the LN Engineering IMS Retrofit kit and IMS Pro Tool Kit based off the procedure developed by Flat 6 Innovations and LN Engineering LLC.
The procedure outlined by the Bentley video allows for extraction of the original factory sealed ball-bearing in model year 1997 through 2005 Porsche Boxster and 911 vehicles and replacement using LN Engineering’s IMS Retrofit bearing.
When replacing the factory Porsche single row IMS bearing with the LN Engineering Single Row Pro IMS Retrofit, the 106-08.22 Faultless IMS Tool must be used. The Single Row Pro IMS Retrofit replaces the factory single row IMS bearing in 00-05 Porsche Boxster and 911 models with a dual row bearing. The new bearing is retained using an internal wire lock. The Faultless IMS Tool allows for the bearing and wire lock to be installed at the same time. Without this specialized tool, it is not possible to install the bearing with the required wire lock. The video to the left shows the Single Row Pro IMS Retrofit and how to use the Faultless IMS Tool.
If you are planning on replacing the intermediate shaft bearing in a Porsche Boxster or 911, you may want to consider using the IMS Solution which is the only permanent fix for the IMS issue where all other ball or roller bearing ims replacements have manufacturer recommended service intervals as part of scheduled maintenance.
This video goes over the IMS procedure when fitting an IMS Solution to a Porsche Boxster or 911 engine.
The 106-08.13 IMS Pro Tool Kit is required for all IMS bearing installations. The IMS Pro Tool kit includes the required bearing puller and driver, camshaft, and crankshaft locks for installation of IMS Retrofit, IMS Solution, and RND RS Roller IMS bearing kits. Kit also includes adapters to pull stock and LN IMS bearings as well as our ez-out tool which allow removal of the stock bearing when the center stud breaks during bearing extraction.
Faultless Tools IMS Removal & Installation Tool
The 106-08.22 Faultless IMS Tool is required for installation of the 106-08.2.2 Single Row Pro IMS Retrofit. Installation of our patented Single Row Pro IMS Retrofit is carried out with our Faultless IMS Tool, allowing for positive retention of the new dual row bearing with an internal wire-lock, replacing the original single row bearing with a new bearing that is twice as strong as the original Porsche single row IMS bearing.
