Salamander RHP100 pump leaking

[Dollytubs18]

Our salamander whole house pump appeared to have a slow seeping leak from the end black parts. I think we should change the o ring and have bought a set of new salamander o rings. Trouble is having undone the hex bolts and nuts the black housing won't come off to expose the o ring. Is there something else we need to undo or does anyone have any instructions for changing the o rings. Thx

I`ll take a stab in the dark. The end caps need to be worked out, most likely protude inside the housing somewhat. Any cut outs either side to insert screwdrivers.

Thank you will give that a go. Didn't want to prise it off Nd break it if there was something else to undo. Many thanks for your time.
