The peculiarities of servicing some Shimano spinning reels has been discussed in a previous post. Input from a member who spoke with a Shimano American Corp. Service rep. identified that when you remove the cover from the service plate, the potential for gear problems has already occurred. Here is the link, the first part of the post provides the details:

I find it interesting that Shimano tells you how to remove the cover in the instructions for the Stella reels, "in case you want to service the reel yourself". I also find it interesting that there is no mention that when doing so, you run the risk for problems, and
be sure to only use Shimano lubricants if you want to keep your warranty. Apparently this specific information is closely held by Shimano, and not for public use? I couldn't find any information in the documentation that came with my reels, on what lubricant to use.
I looked at the warranty cards that came with my 4 Stellas, and I guess that lubing a reel with anything other than Shimano approved lubricants is to be considered "...an unauthorized alteration, abuse or damage by your failure to provide necessary and reasonable care." I also noted that the warranty card goes on to state that "Some states/provinces do not allow limitations on how long an implied warranty lasts nor do they allow the exclusion of incidental or consequential damage: therefore, the above stipulated limitations and/or exclusion may not apply to you."
Standing back, it sure sounds like that there already is a known problem in servicing these spinning reels to me... irregardless of what lube is used.
