Replacing Travel Indicator Assembly
When performing maintenance on the original
Type 1098-EGR body flange, travel indicator
replacement is recommended. The redesigned
travel indicator assembly is incorporated into all
Quick- Change Trim Kits and on the Travel Indicator
Kits. The elastomer repair kits contain the components
for the redesigned travel indicator assembly.
1. Remove the travel indicator assembly by removing
lower indicator fitting (key 5) from the body flange
(key 2).
2.
Coat the threads of the lower indicator fitting
(key 5) with a good grade of general-purpose grease.
3.
Install travel indicator assembly (10C1212), torque
to 40 ft-lbs / 54 N•m.
4. Check indicator zeroing by unscrewing the
indicator protector (key 19) and seeing if the flange
of the indicator nut (key 22) lines up evenly with
the bottom marking on the indicator scale (key 18).
If not, remove the indicator scale and separate
the indicator nut and hex nut (key 8). Hold the
indicator scale against the indicator fitting (key 5)
with the scale base resting against the shoulder of
the fitting and turn the indicator nut until its flange
is aligned with the bottom scale marking. Then
lock both nuts against each other and install the
indicator scale and protector.
Replacing Trim Parts
Perform this procedure when inspecting, cleaning or
replacing individual trim package parts. Key numbers
are referenced in Figures 11 and 12.
Note
Access to the spring (key 9), flange
O-ring, travel indicator parts or optional
travel stop (key 32) in step 1 can be
gained without removing the body
flange (key 2).
1. Remove the travel indicator assembly by removing
lower indicator fitting (key 5) from the body flange
(key 2). Proceed to step 5 if maintenance on
only the travel indicator parts is needed and then
proceed to step 11 for reassembly instructions.
2. Remove the cap screws (key 3) on a cast iron
body or remove the stud bolt nuts (key 29, not
shown) on a steel body and pry the body flange
(key 2) loose from the valve body (key 1).

3.
Use the valve body (key 1) as a holding fixture
if desired. Flip the body flange (key 2) over and
anchor it on the valve body as shown in Figure 10,
removing the pipe plug (key 31) first if necessary.
4.
To gain access to the port seal (key 12), upper seal
(key 15) or valve plug (key 16) part, unscrew the
seat ring (key 13) from the cage (key 11) and the
cage from the body flange (key 2). For leverage,
a wrench handle or similar tool may be inserted
into the seat ring slots (Figure 10) and a strap
wrench may be wrapped around a standard or a
Whisper Trim
™
Cage or a soft bar may be inserted
through the windows of a standard cage. To remove
the piston ring (key 14) and/or plug O-ring (key 20),
remove the valve plug (key 16) from the body
flange, insert a screwdriver into the precut fold
over area of the piston ring and unfold the piston
ring. Proceed to step 6 if no further maintenance
is necessary.
5. To gain access to a part in the travel indicator
assembly, remove the indicator protector (key 19)
and indicator scale (key 18). Since some
compression is left in the spring,carefully remove
the flanged nut (key 22) and hex nut (key 8). A
screwdriver may be inserted through the press-fit
bushing (key 6) to remove the stem O-ring without
removing the bushing. If necessary, unscrew the
travel stop (if used) and unclip the E-ring from the
indicator stem.
