4kq- Removed vacuum pump

[Frederick Smith]

Having dissected a few of these pumps I can tell you it's
almost impossible to put them back together without some
special tools. If I remember correctly there is either a
spring or metal diaphragm in there along with a few white
nylon/plastic valves or such. Compressing the spring AND trying
to catch the screws fro the cover if difficult. SOme kind of
clamp or arbor press would make it easier.........but not easy.
