Ryobi ry30020a

[Jorge perez]

I have a ryobi trimmer ry30020a, while i was using it a lot of smoke came out from the spool at the end of the trimmer.
I found out that the housing (part number 099068001005) that contains the spool, melt at the base of it. I still do not know how it happened, it looks as if the nut inside (made out of metal) broke down, making the housing to loosen and at high velocity touching the shaft it melt the plastic.
I am having problems intaking the spool retainer out of the shaft, so can you please tell me how can i get it out ( before this it was very easy pushing down the spool an then turnin the spool retainer down and counterclock wise). And if i buy this parts here can i get them sent to mexico?
Thanks for your help
