Stilo Accumulator Replacement

Ok. This is optional but it makes removal much easier.

The instructions just say to remove accumulator but there is not much room for a spanner. So I bought a 27mm ring spanner. Bent the open end 90deg with a gas torch then ground a 3mm chamfer on the upper side of the jaws so it sat snug up against the accumulator and the jaws did not extend below the hex on the accumulator (a custom crows foot spanner)
Note chamfer on jaws.
