intermediate shaft failure prevention

Now available exclusively to Autofarm here in the UK, this technology from LN Engineering in the U.S can upgrade your engines weak intermediate shaft with a stronger bearing and prevent the possible failure from occuring and potential large builds in the future.

The bearing on the Intermediate Shaft (IMS) is considered to be a weak point of the M96 series engines featured in all 986 Boxster, 996 Carrera's and some early 997 Carrera's. When rebuilding an engine we replace the intermediate shaft as a whole with the latest 997 style shaft. This is a feature of all our modern engine rebuilds and partly how we get such excellent reliability. However, this is not very cost effective as a preventative measure as to replace the shaft the whole engine has to be dismantled and reassembled.

With this kit developed by LN Engineering in the U.S we can replace the bearing with the engine in situ (on Boxsters and 2wd Carrera models) as easily as changing the clutch and flywheel. You could change these items at the same time to save on labour costs in the future.

First we drain the oil and check it for metal debris and particles. This preventative measure cannot be carried out on a bearing that has already failed or is failing.
We check inside the oil filter as well as the housing. Our fixed price job includes an oil and filter change.
Where possible we will carry out the replacement with the engine still in the car. This isnt possible on 4WD models. Here we see the exposed IMS and crankshaft once the flywheel has been removed.
Special tools are required to remove the flange and bearing housing without disturbing the engine internals.
This picture shows the bearing puller attached ready for extraction.
The new bearing is then carefully installed.
The new bearing also includes an improved flange and seal.
All done, the flywheel, clutch and gearbox can now be reinstalled.
