If the lifter has VPFS10T vacuum
pads, replace sealing rings
(
#49724RT
or
#49724TT
) as
follows:
1) Remove the old sealing ring
(fig. 1A).
Note: Make sure the entire
vacuum pad is clean,
including the mounting
groove.
2) Place the inside edge of a
new sealing ring against
the inside edge of the
mounting groove (fig. 2A).
3) Push the sealing ring into
the mounting groove,
beginning in 4 locations as
shown circled in fig. 3A.
4) Push gently and firmly on
the outside edge of the
sealing ring until the flat side
fits flush against the bottom
of the mounting groove (fig.
4A). A pad ring installation
tool (circled in fig. 4A) makes
this step easier (see
).
5) Make sure the sealing ring
seats securely in the
mounting groove, all the way around the vacuum pad (fig. 5A).
Note: If any part of the sealing ring comes out of the mounting groove, inspect the sealing ring
for damage and reinstall an undamaged sealing ring.
