Thanks Herb, the electric drill works a treat and all you need is a 15mm 1/2" drive socket on the drill to fit on over the pump splines. Pressures could be monitored by inserting a Tee and gauge on the outlet side of the pump. We didn't do that as we have decided that the slow door closing is probably because the power pack needs overhauling and pressures re-adjusting in the process.
