2)
For Santoprene fitted pumps place the inner plate (item
23) over the bolt so that the round groove in the inner
plate faces the diaphragm. For PTFE fitted pumps place
the small diaphragm o-ring (item 22) into the groove of
the diaphragm. Then place the inner plate over the bolt
so that the round groove in the inner plate faces the
diaphragm.
4)
The shaft (item 27) and shaft bushing assembly (items
24, 25 & 26) should retain the lubricant that was
factory applied. If they appear dry, apply a light coat
of lithium thickened grease. Avoid over lubrication as it
can cause decreased performance of the air distribution
system.
1)
Slide the center hole of one diaphragm (item 20) over
the molded in bolt of an outer plate (item 19).
For both PTFE and Santoprene™ fitted pumps the outer
plate should be on the convex face of the diaphragm as
shown.
3)
Apply a medium strength thread locker, such as Loctite
®
246, to the outer plate (19) bolt threads and shaft (item
27) threads. To ensure thread locker cures quickly, a
primer such as Loctite
®
SF7649 should be used. Thread
the shaft onto the outer plate bolt until it is snug.
