Update Armed with my red grease i set about the large o ring, i swore at it before fitting to tell it who's boss When fitting i found trying to gentle wiggle and push it down to a level where you could then start threading the three screws didn't happen without a problem but having done a search on the forum, i then used three longer bolts with a nut and wound down the bolts to where they bottom out in the hole and then a few turns of the nut on each bolt, pulled the plate in nice and even, left for 30mins and no leaks, started her up and left to cool down and all good Went out for my first ride of the season only 20 miles as trying to see how my wrist is behaving since the tendon snapped was good to have a ride
