Ive got the back housing off and the big o-ring out but i cant seem to get the next back preesure plate off. ive done a search but othing really of help. i dont wanna go off like a shot out of a gun and damage something
just tap the front shaft to push it in, it'l pop out then, then you need to take the circlip off the rotor, dont loose all the little wings, then you can pull the whole shaft out so you can then get at the front seal to replace it, just remember which way the pressure plate goes back on, if you dont have those 2 holes lined back up right you'll have no pressure as it's blocked off.
ok ive done another search. i have one front seal. 2 big o rings and 2 o rings. one goes under the high pressure line. but the other one?
ive searched the hole pump. i cant find a second o-ring and it looks too big to fit on the high pressure line hose. its the same size o-ring that goes under the high pressure valve
you have to undo the bolt at the back of the pump where the high pressure line goes, there's a spring it sits in there.
