Maintaining the MSD
To lubricate the side plate O-ring
To lubricate the side plate O-ring
Materials needed:
Cloths, clean (05980-60051)
Gloves, clean, lint-free
large (8650-0030)
small (8650-0029)
Grease, Apiezon L, high vacuum (6040-0289)
The side plate O-ring needs a thin coat of grease to ensure a good vacuum seal. If
the side plate O-ring appears dry, or does not seal correctly, lubricate it using this
procedure.
1
Vent the MSD (page 52).
2
Open the vacuum manifold (page 54).
3
Use a clean, lint-free cloth or glove to spread a
thin
coat of high vacuum
grease on the exposed surface of the O-ring.
4
Use a clean, lint-free cloth or glove to wipe away excess grease.
If the O-ring looks shiny, there is too much grease on it.
5
Close the vacuum manifold (page 56).
6
Pump down the MSD (page 56).
& $ 8 7 , 2 1
Vacuum seals other than the side plate O-ring and vent valve O-ring do not need to be
lubricated. Lubricating other seals can interfere with their correct function.
& $ 8 7 , 2 1
Excess grease can trap air and dirt. Grease on surfaces of the O-ring other than the exposed
surface can trap air, resulting in air spikes during operation.
