Can anyone tell me why there is an extra, large oring in each repair kit? also which way does the piston go in shallow / flat end first or deep end first. Didnt pay attention when i removed them.

im sorry but in that pic it shows flat end toward opening therefor hollow end first. No?

 

[blando]

flat end is closest to o ring

maybe i should clarify... which end of the piston is facing the closed end of the tube? looks like flat end id facing open end?
