recheck  the  film  seat  gap.    Remove  this  sub-
assembly and store on a clean surface. 

O-RING SEAT PALLET 

Remove  the  retaining  ring  [28],  the  retainer 
plate [30] and two O-Rings [29 & 31].  Inspect 
and  clean  the  O-Ring  groove  and  the  bore  in 
the  pallet.    Install  new  O-Rings,  and  replace 
the  retainer  plate  [30]  and  retaining  ring  [28]. 

Do  not  expand  the  retaining  ring 
excessively.

BODY SEAT INSERT 

The  seating  surface  is  a  thin  stainless  steel 
insert [27] bonded into the body.  The flat top 
surface  contacts  the  O-Ring  in  the  standard 
pallet  assembly.    The  corner  radius  contacts 
the  tensioned  film  of  the  optional  pallet 
assembly. 

Inspect the appropriate surface to be sure it is 
clean,  smooth  and  flat.    Press  and  twist  the 
insert  manually  to  verify  that  it  firmly  bonded 
into the body. 

If  the  O-Ring  pallet  is  used,  the  flat  sealing 
surface  of  the  insert  may  be  lapped,  using  a 
flat lapping block. 

If  the  film  pallet  is  used,  the  sealing  radius 
may  be  hand  polished,  very  carefully.    The 
radius  must  be  uniform  and  not  exceeding 
.030

ASSEMBLY

Model  1660A:  This  model  has  one  support 
plate riveted [3] to the spindle cap.  Screw the 
jam  nut  [47]  onto  the  spindle  rod  [13]  and 
screw the rod  into the spindle cap [22] until it 
is  flush  with  the  top  surface  of  the  support 
plate [4].  Then tighten the jam nut securely.

Models 

1661A+1662A: 

The 

actuator 

diaphragm  is  mounted  between  the  upper 
(vacuum)  [4.1]  support  plate  and  the  lower 
(pressure)  [4]  support  plate.    Thread  the 
spindle rod [13] through the upper spindle cap 
[22].

Temporarily  seat the  spindle  tube  against  the 
cap  and  adjust  the  rod  until  it  extends  3/16

” 

beyond  the  lower  end  of  the  tube.    Remove 
the tube  and  install the O-Ring [48],  pressure 
support 

plate 

[4], 

diaphragm 

[15], 

Fluoropolymer  washer  [50],  vacuum  support 
plate  [4.1],  and  flat  washer  [49].    Install  the 
jam nut [47] and tighten securely.
