Proper RMS Install Procedures

Recommended Posts

I've read in a several forums that there are many different "theories" as to the best way to seat a RMS - with regards to lubricant/sealant (excluding discussions about the tool).

Speaking of the latest version of seal for a 996.

The original work shop manual says the outer flange must go in dry. The inner crankshaft surface, inner seal, and plastic installation piece should be lubricated with heavy weight motor oil. Of course, since the original WSM was written, there have been many changes to the RMS seal.

To this point, there are many different "ideas" I've read about. I am thinking that perhaps 3 is the only right answer, except perhaps using some light oil on the inner seal surfaces to aid installation and prevent scorching the RMS.

1.) Apply curil-t to the outside flange.

2.) Spray WD-40 on the inner flange instead of motor oil.

3.) Install the entire seal dry (including inner surface). The PTFE (teflon) coated treatings are all that are required for installation and normal operation.

# 3 is the right way to go, the way we had to work was as followed: clean the crankshaft contact surface with a polish (Never Dull or similar product available in Harley - Davidson shops) / install with special tools the new seal (dry) / let sit the seal and the tools for 10 minutes / remove the special tools. Never had problems with subsequent leakage.

Thanks RFM. So no oil then to lubricate the inner shaft surface, as per the 996 WSM?

I was looking at TSB 1359, however I don't have access to a 9PA work shop manual.

Would any one happen to paraphrase or post the RMS install procedures from a Cayenne? Probably a long shot though, posting this in the 996 forum.
