I had a suggestion from a technician who does vacuum pump service from at least 10 years... He told me (referring to my Edwards) to use diesel to clean the inner parts of my pump(not the oil tank), doing so I don not have the need to dismount all, and replace some metal seals I do not have... All I need is diesel and some pump oil for draining.
Steps: 1. Turn on the pump 2. slowly add a few diesel from the vacuum port 3. let it run (minutes) 4. repeat from point 2 a few times 5. drain the oil (dirt should be seen in the oil, I guess)
Doing this a few times should remove dirt from the "pumping zones" of my direct drive. Leaving me with a near new babe.
I will give this a try in the evening, then I'll post results...
ciao all Daniele
