@@MichaelS3013 I'm not sure, but I made 0.1 mm of clearance and used Teflon tube rings to prevent metal/metal contact. I'm currently installing it instead of menbrana. I don't know if you've seen my last video. You may be interested
@@LechoslowianinI'm looking at it now. Thanks for the information. I will recognize the moment of truth when the vacuum motor has to make its first run. Greetings Michael
@@MichaelS3013 My cylinder and piston are made of aluminum. When I moved it a little, the scratches were already visible. In your case it may be different because your cylinder is made of bronze and the piston is probably stainless steel. The type of material is very important. Regards
