My J 250 manual indicates "Vogel Doser 10" lube oil metering units with a total of 15 installed. I'm pretty sure I have some partially if not fully plugged as I have a couple on the saddle ways that are gushing oil while others not so much. I've heard these are a PITA to get cleaned properly and was considering just purchasing new replacements. After searching high and low on the web I can not find a cross reference for Vogel Doser 10 size. Does anyone know the correct replacement for say a Showa meter unit? Is there a need to use various sizes depending on what it services? I've seen on the J325 they use a size 00 Bijur on all the ball screws with most everything else a size 2 or 1. Granted different pump, different pressures, etc. Just trying to ensure lubrication is working properly and correctly to all end points on this 27 yo hunk of iron.

Thanks
