If the vacuum lifter has VPFS625 vacuum pads 

(#58383)

, replace its pad inserts 

(#49726)

:

Note: The Pad Repair Kit 

(#58387)

 also includes associated hardware. Instead of setting aside 

and reusing the existing hardware as directed below, use the hardware supplied with the kit.

1)  

1A

1B

Remove the 1/4-20 

lock nuts and washers 
that secure the top 
plate to the face plate 
of the pad assembly 
(fig. 1A).  Then remove 
the top plate (arrows 
in fig. 1B).

Note: Set aside the removed hardware.

1

2)  

2A

2C

2B

Remove the old pad 

insert (fig. 2A). Then 
remove the white 
spacers (fig. 2B) from 
the old insert and set 
them aside.

Note: Leave the pad’s 
filter screen 

(#15630) 

in place (fig. 2C).

3)  

3A

4A

Inspect the edge of 

the new pad insert, to 
determine which side 
of the insert’s face has 
the smoother edge 
(circled in fig. 3A).

Note: The difference in 
the edge’s smoothness 
will be subtle.

4)  Install the new pad insert, making sure the smoother edge faces down (fig. 4A).

1..... A pad repair kit 

(#58387)

, which includes a replacement pad insert as well as the hardware required to install it, is also available.
