I've got two tools that I bought from Pfeiffer after using a screwdriver and a washer and skinning my knuckles again. Parts are as follows: Oil Change Tool - PV M40 061 (This is a little stubby affair that opens the slotted type of cover found on the 262 Turbopumps) Oil Change Tool - N 5709 103 (This is a longer tool with two blunted prongs that fit into either side of the other sort of cap that you find on the 071 Turbopumps) To be honest, any good machine shop could replicate these tools as they look very simple to construct.
