Porsche Boxster 986 IMS Intermediate Shaft Bearing Upgrade - Eternal Fix - 97-04
If you are reading this then you are aware of the ever so common IMS Bearing Failures on 986 Porsche Boxsters. The design flaw with the factory IMS was the use of Ball Bearings in an extremely high load application. Once the Ball Bearings Fail it leads to a Catastrophic and Expensive engine rebuild. The Patent Pending IMS Eternal Fix Retro Fit installs in-car without removal or disassembly of the engine required. The Cylindrical Bearing with Thrust Control design has a load capacity 5 times greater than the inferior, failure prone, Ball Bearing solutions on the market! We also offer fully Rebuilt Intermediate Shafts Upgraded with the Eternal Fix Trade Mark for those performing an engine rebuild.
Porsche IMS Intermediate Shaft Bearing Upgrade - Eternal Fix - The Last Fix You'll Ever Need!
- Prevent future catastrophic engine failure
- BALL BEARINGS ARE NOT THE SOLUTION! - Do Not Replace The Factory, Failure Prone, Ball Bearings With A Ball Bearing "upgrade" As They Too Will Fail!!
- Permanently Fix Your Intermediate Shaft With The Eternal Fix!
- Unlike Failure Prone Ball Bearings, Eps Uses A Patented Cylindrical Bearing With Thrust Control.
- Holds 5 times the load capacity of ball bearings
- The Patent Pending IMS Eternal Fix Retro Fit installs in-car without removal or disassembly of the engine required.
- We also offer fully Rebuilt Intermediate Shafts Upgraded with the Eternal Fix Trade Mark for those performing an engine rebuild.
- 2 Year Warranty
Why Cylindrical Bearings Are Superior to Ball Bearings:
Cylindrical Bearings have very high load bearing capacity, 5 times more than Ball Bearing. Cylindrical Bearings are used in, High Temp & Low Viscosity Lubrication such as Automatic Transmissions. They can carry extreme lateral pressure without wear to the friction surfaces. This is because the bearing friction surface is flat not concave.
What's in The Box:
- Porsche EPS Intermediate Shaft Bearing (IMS) Upgrade
- IMS Pressurized Oil Feed Modification Kit
How Does the IMS Eternal Fix Work?
A - Lubrication Cavity Feed : Located on the Retro Fit Base (D), this cavity is the lubrication entry point which provides the Cylindrical Bearings, Bearing Races and Friction Plate with a continuous supply of engine oil ( See FIG 3 ) . While the engine is running, this area is saturated with engine oil as it is located in the bottom of the engine case, where much of the engine oil pools. Please also see the video at the bottom of the page. Also included is the new IMS Pressurized Oil Feed Modification Kit (See Bottom).
B - Bearing Race: The Bearing Race is the raised hardened steel surface edge of the Bearing Chassis (located on either side of the Bearing). This surface provide a friction point with the Retro Fit Base (D) and the Friction Washer (C). This provides the patent-pending axial thrust control required when using Cylindrical Bearings.
C - Friction Plate: The Friction Plate is a hardened steel washer that provides the inner friction point with the Bearing Race (B)
D - Retro Fit Base Friction Surface: This provides the outer friction point with the Bearing Race (B)
E - Retro Fit Base Friction Surface: The Cylindrical Bearings provide the radial load support for the IMS. Cylindrical Bearings have a load capacity of more than 5 times that of their Ball Bearing counterparts. Cylindrical Bearings are commonly used in very High Load, High Temperature, Low Viscosity Lubrication applications such as Automatic Transmissions.
Bonus Item! - IMS Pressurized Oil Feed Modification Kit
The IMS pressurized oil feed kit allows you to maintain a constant, fresh oil flow to the IMS bearing. Please CLICK HERE for the step by step procedure for pressure feeding the IMS bearing with engine oil. This is achieved by punching a small in the cover at the front of the IMS. The front cover is a very thin metal plug, only .25MM thick. Using the included center punch and a hammer the hole can be opened with relative ease.
The Oil Pump's factory 8MM Allen drive is then replaced with a slotted 8MM drive. The slot on the new 8MM drive will provide a governed oil passage from the oil Pump pressure side into and through the IMS. This pressurized oil will flow through the IMS and in to the the IMS bearing. This will maintain a constant, fresh oil flow to the IMS bearing.
EPS recommends professional installation for the Eternal IMS Fix. Please take all precautionary safety measures. We also recommend putting the engine in TDC and locking the crankshaft and camshafts in place to assure there is no chance of jumping timing while working on the intermediate shaft and its bearing. Please read through the COMPLETE instructions to familiarize yourself with the process, BEFORE you attempt to do it for the first time.
