Question: Damaged Cushion
I have an Echo grass trimmer, model # SRM-2100, SN#850952. Using your diagrams I conclude that the part I am having a problem with corresponds to part E-12, the "Cushion". When assembled, the cushion is inserted into the fan cover assembly (E-14) so that it's rectangular projections extend through the rectangular holes in the cover. Then, the holders (E10 & E11), are inserted so that THEIR rectangular projections extend THROUGH the corresponding extensions on the cushion. So, from the outside, these elements give the appearance of an internal piece with rectangular pins extending through rectangular rubber "grommets" through rectangular openings in the fan cover. I am continuing to have a problem with portions of these "grommets" popping up out of the fan cover, bringing with them a slight leakage of grease/oil. All my attempts to force the grommets back into place from the outside have failed. I now see that the "grommets" are actually portions of a much larger rubber element that have become detached. So it appears I must consider trying to replace the entire cushion. My questions are:
1) have I properly diagnosed the situation?
2) Can you supply me with the proper replacement?
3) Can you provide me with stepwise instructions for that replacement?
4) What is the source of the grease/oil leakage, and what should I do about replacing it?
Thanks for your help.
