Use a 5mm Allen key to remove the four (4)
cap screws holding the rear Gauge Base to
the top of the Manifold Block, then lift the
Gauge Base and its o-ring (
PN
3130) from the
Manifold Block
(figure 12)
.
18
Remove the forward Gauge Base by follow-
ing the procedure outlined in step 16.
If the comparator is fitted with an optional
Fine Adjust Kit, continue to step 19. If not,
you may skip ahead to step 25.
Note:
A comparator without the Fine Adjust
option is instead fitted with an Accessory
Cap, plus an o-ring that should be replaced.
The screws for the plate will require a 4mm
Allen key to remove. Screws included with
older Fine Adjust Kits will require a 5mm key,
while those included with recent, redesigned
kits will require a 4mm key.

Use either a 4- or 5mm Allen key to remove
the four (4) cap screws holding the Fine Ad-
just to the side of the Manifold Block, then
pull the Fine Adjust and its o-ring (
PN
1734)
away from the Manifold Block
(figure 13)
.

Use a 3mm Allen key to loosen the set screw
inside the Fine Adjust knob, then slide the
knob off of the piston
(figure 14)
.
21
Use a 15mm box wrench to remove the Fine
Adjust bushing from the body, then slide the
bushing and its o-ring (
PN
1959) off of the
piston
(figure 15)
.

With the front of the Fine Adjust body facing
toward you, turn the piston clockwise until
the piston threads are clear of the hole in the
back of the Fine Adjust body
