RMS - new and old - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Since I'm in the process of buying a used engine for my Box, I am, of course, going to replace the RMS and IMS bearing. However, I'm wondering if there is a way to visually identify whether the bearing is the new style or the old style. In other words, if I buy an engine that has an RMS that has been replaced with the new style, I don't want to mess with replacing it. I know it's a cheap part, but it's also a part that if not correctly installed, can be a real problem.

So does anybody know if there is any way to visually identify whether or not a car has the new RMS seal (flywheel off obviously)?

normal cars have a number on the seal which can be seen...note i said normal cars

LOL. Yeah.

Is that the Porsche part number? If so, that would rock!

the seal is cheap...so get one before you start the job,that way you can compare numbers,colors etc. if this motor sat for a while i would change it anyway

The latest design RMS is part # 997.101.212.00; this unit requires special tools, 9699 for the main tool, and 9699/2 for the insert guide. If you have access to the Sept. 2010 copy of Excellence, it has a full pictorial showing the differences in the seals and why the new tools are required.....................
