Thanks Martin & mark.
Turned out I’ve got the service / main manual for the Rocky II but thanks anyway!
The advice to use GOOD screwdrivers was appreciated too.
So, all done – hardly any mess and working to 99.9% of what it used to do before (got a minor nozzle deflection in the offending head now).
So here’s my step by step on how to replace the manifold…the bit that we’re all terrified of breaking when you change dampers.
It might not be the ‘technician approved method’ but it worked as I was winging it.
Trimmed down the excess plastic on the manifold to suit the odd fitment issues on a Tiara.
Popped off the damper(s), wiggled out the ribbon cables marking L&R
Undid the two head retaining screws (metal bridge with plastic under it) and noticed that the spring to push the head over (alignment) made removal trickier.
Head out & on bench.
Flipped it over & ALMOST take out two tiny screws holding manifold on.
Push on screws to eject the nuts from the recess & take out screws totally.
Lift off manifold.
Decide whether or not you fancy replacing the wee gasket (comes with the kit).
Put screws back in a GENTLY do them up – do NOT tighten, it’s just enough EVEN PRESSURE between them to hold it down.
Reinsert head into the holder and gently tighten it up.
Now for the spring…yes, might have been easier to fit it between the head & the holder during the head install but easy enough to insert from the bottom, compress it up with a finger and pop it over the tab with a small driver.
Dampers on & ribbons in.
Power it up & offer up a prayer.
Pull ink through, test it…go ‘yay’ and vow to never do it again.
