5. Remove gland from boring bar.
6. Place gland in a vise or clamp so
that packing will not “spring” out of
gland when the two retaining pins
(Part No. 47092) are removed.
7. Remove retaining pins.
8. Model 3 and prior: Remove
concave follower, four packing rings,
convex follower, and spring from the
gland.
9. Remove any burrs from the boring
bar drive lugs. Lubricate the boring
bar and inside of the new packing
rings with a light lm of oil or cutting
grease.
10. Remove cap screws from
alternate tapped holes in gland.
11. Replace boring bar wiper ring
(Part No. 501158) and gland seal
(Part No. 52162) if necessary. Place
gland on boring bar being careful not
to damage packing ring or the wiper
ring.
12. Slide gland into ange recess.
Insert and tighten cap screws
securely.
13. Replace hub retaining bolt and
nut.
Cutters
SHARPEN CUTTERS AND PILOT
DRILLS BY TOUCHING THEM UP
WITH AN OILSTONE BEFORE
EACH CUT. If the cutters are
very dull, return to Mueller Co. for
reconditioning.
OILING (Model 4, 5 & 6) for model
3 or earlier call Mueller Customer
Service.
Keep the drive box and rear gear
case of torque tube half full of a
good grade, extreme pressure semi-
uid gear oil with a Saybolt Universal
Viscosity of 80-85 seconds at 210°F.
Change oil periodically. Drain old oil
and replace with 4 pints in drive box
and 1.6 pints in rear gear case of
torque tube. Mueller Part No. 89347
gear oil is used and needs not
thinning in cold weather.
Packing
Boring Bar Packing is the self-
adjusting type. If packing leaks.
Replace it as follows:
1. Remove hub retaining bolt (Part
No. 545513) and nut (Part No.
61707) from boring bar.
2. Remove 4 cap screws (Part No.
53542) from the gland (Part No.
501151).
3. Insert cap screws into the
alternative tapped holes in gland
and screw them in all the way. This
should be done evenly, tightening
each cap screw a little at a time. This
will cause the gland to move forward
evenly out ot the gland recess until
the gland seal (Part No. 52162) is
exposed.
4. Rotate crank handle (Part No.
88150) counter-clockwise and
advance boring bar 6 or 8 inches.
This will cause the gland to move
forward into an exposed position.
CAUTION: Keeping cutters
sharp assures maximum
efciency in cutting operations.
When cutters are dull they not
only make cutting more difcult,
but place an additional strain on
the teeth which can cause tooth
breakage. When not in use, keep
cutters in the machine chest or
other wooden container. (NOTE:
Be careful not to drop cutter and
damage cutter teeth.) If necessary
to rest cutter on teeth, place upon
wood rather than brick, concrete,
or metal.
After Use
Clean dirt, etc., from machine and
equipment. Give cutters, drills,
and equipment a light coat of oil to
protect them from rust.
Storage
When not in use, the machine and
equipment furnished with each
machine should be stored in the
chest furnished with the machine.
NOTE: If the machine is stored
or transported in the vertical
position. It is recommended
that before use it be placed in a
horizontal position for a short
period of time (1/2hour), to allow
grease to drain back into the rear
grease case.

b) 2½”– 3”/DN65 – DN80. Assemble
both the pilot drill and the shell
cutter to the cutter arbor Remove
retaining screw from the shank of
the arbor. Insert the shank of the
arbor into the socket in the boring
bar. Align the bolt hole in the end
of the boring bar with the tapped
hole in the shank of the arbor and
replace the retaining screw.
c) Sizes larger than 3”/DN80.
Assemble shell cutter and cutter
hub. Insert the end of the pilot
drill into the socket in the boring
bar. Slide cutter hub and shell
cutter over the end of the boring
bar. Align the holes in the cutter
hub, boring bar and pilot drill
and attach to boring bar with hub
retaining bolt.
Coat cutter and pilot drill thoroughly
with Mueller cutting grease. DO NOT
use cutting grease when cutting AC
or concrete pipe.
6. The term “valve”, as used in these
instructions, refers to whatever
type of valving means that is being
used between the machine and the
main. This might be a tapping valve,
standard gate valve or line stopper
tting. If valve is being used, open
completely and measure, or check,
the exact size of opening and size
of cutter to make sure the entire
opening is clear and unobstructed
and the cutter will pass freely.
7. Retract boring bar to its rearmost
position by rotating feed crank
clockwise.
8. Place the machine (with adapter
and drilling equipment assembled) in
drilling position. For horizontal use,
support the assemble by blocking up
under the machine and valve.
NOTE: Make certain machined
recess on adapter and lip on
adapter ange and machine
ange to be sure they are ush.
1. INSPECT CUTTER AND PILOT
DRILL TO MAKE SURE THAT THEY
ARE SHARP. IF CUTTER IS DULL
IT SHOULD BE SHARPENED AS
DESCRIBED IN MAINTENANCE
INSTRUCTIONS.
2. Bolt proper size adapter to front
of machine, being sure machine-to-
adapter gasket is in good condition
and in place. (All gaskets should be
replaced periodically.)
NOTE: Make certain machined
recess on adapter and lip on
adapter ange and machine
ange are ush.
3. Release automatic feed by
pulling out automatic feed knob or
disengaging with Auto Feed Lever.
(Directions are indicated on panel on
rear of torque tube.)
4. Advance boring bar by rotating
feed crank counter-clockwise until
hub retaining bolt in boring bar is
exposed beyond face of adapter.
(Directions are indicated on panel on
rear cover of torque tube.) Remove
hub retaining bolt.
5. Attach proper drilling equipment
to boring bar. Check detent type
pilot drills before each operation to
make sure the detents will move
completely to the submerged
position.
a) 1½”– 2”/DN40 – DN50. Remove
the retaining screws from the
shank of the drill. Insert the shank
into the socket in the boring
bar. Align the hole in the end of
the boring bar with the tapped
hole in the shank of the drill and
replace the retaining screws. See
instructions under CAUTION on
page 5.
a) Place machine and adapter
against valve, allowing cutter to
extend into the end of the valve.
Cutter must not interfere with
operation of the valve. (When
machine is used horizontally, the
driving spindle should be at a right
angle to the main.) Bolt adapter to
outlet ange of the valve, making
certain that the adapter gasket is
in place.
9.Test set up for pressure tightness.
10. Rotate feed crank counter-
clockwise to advance boring bar
until pilot drill contacts the main. One
turn of the feed crank moves the
boring bar 1/6“ (4mm) – 6 revolutions
equal 1” (25mm). For C1-36-99002
machine, 8 revolutions equal 1”
(25mm). Back up boring bar 1/4 turn
of feed crank clockwise to release
tension between pilot drill and main.
11. Engage automatic feed by
pushing in on automatic feed knob.
12. Rotate feed crank clockwise
until dive key engages. This can be
felt when feed crank ceases to freely
rotate.
13. Set feed indicator to zero. Mark

18. Unbolt adapter from valve and
remove adapter and drilling machine
from valve as a unit.
19. Advance boring bar by rotating
feed crank counter-clockwise and
remove hub retaining bolt, (retaining
screw from cutter arbor or retaining
screws from shank of solid drill.)
Remove cut-out section of pipe, shell
cutter, cutter hub or cutter arbor and
pilot drill as a unit.
20. If cutting operation becomes
difcult, follow one of these methods:
a) If cutter has difculty in cutting,
becomes dull or should stall
after the cut is started, withdraw
the cutter, close valve, remove
machine and sharpen or replace
cutter. Reassemble and proceed
in the regular manner.
b) If cut is well along, release
automatic feed and feed machine
by hand by holding back on
the feed crank at the rear of
the machine a little each half
revolution.
NOTE: Automatic feed should
be used whenever possible.
Automatic feed also provides
the correct tool feed.
14. Continue the cutting operation
until the cutter stops cutting or until
feed indicator reads the amount
shown in the travel chart. (See
pages 7–10 for travel chart).
15. Check completion of cut by
releasing automatic feed and
attempting to advance cutter by
rotating feed crank. If it does not
advance easily, the cut is not
completed and automatic feed
knob must be pushed in to engage
automatic feed for further cutting.
CAUTION: Stop advancing
the boring bar when the limit line
becomes visible through the drive
box drain hole. See illustration at
bottom of page 5.
Watch the travel carefully when
making a 11/2”/DN40 or 2”/DN50
cut. Make sure that the front end
of the boring bar, which is larger in
diameter than the drill, does not hit
the valve seat.
16. When cut is completed, release
automatic feed and withdraw cutter
to its rearmost position by rotating
feed crank clockwise.
17. Close valve securely.
IMPORTANT: Stop advancing
the boring bar if the limit line
becomes visible through drive
box drain hole. It will result in
extensive damage to the machine.
This applies to C1-36 machines
manufactured prior to September
1, 1995. C1-36 machines manu-
factured after September 1,
1995, or rebuilt after this date
and that have “OT” or Model 6
stamped on the name plate have
an overtravel protection feature
which is designed to prevent
damage should the boring bar
be inadvertently advanced too
far. Machines should never be
allowed to overtravel. Feature
does not prevent damage to the
feed screw that could occur as
a result of using dull drills or
cutters.

Care must be taken to not over tighten
as the material is aluminum. (D.)
7. Replace the shims under the
travel indicator in the same position
as removed in step 4. (D.)
8. Mount the clamp to the mounting
plate with the (4) 1/4”-20UNC x 1/2”
long bolts and lock washers. (E.)

1. Drive the retaining pin from the
automatic feed knob with a punch.
Position the knob so the pin can be
easily removed. Discard the knob. (A.)
2. Reuse the pin to attach the spool
piece from the kit. The pin will go
into the same hole used to hold the
knob. Once installed, ensure the
pin does not stick out into groove of
spool piece on either side. (B.)
3. Loosen the (2) hex bolts on the
top back of the travel indicator
mounting plate. (C.)
4. Before removing bolts check to
see if shims have been used to align
the indicator with the idler shaft.
If shims have been used, these
will need to be placed back in the
same position when attaching the
automatic feed lever. (C.)
5. Remove the (2) hex bolts and
discard. (C.)
6. Mount the base plate of the
automatic feed lever to the mounting

the kit. Orient the bracket with the
side marked “top” toward the head of
the bolt when inserting the bolts. (F.)
10. Secure the mounting bracket fork
against the head of the bolt using a
5/16”-18UNC hex head nut and lock
washer. (F.)
11. With the idler shaft and spool in
the pulled-out position (disengaged),
place clamp handle in the upright
position. (F.)
12. Install a 5/16”-18UNC hex head
nut onto the 5/16”-18UNC x 31/2”
bolt and a lock washer. This nut
and washer will be used to properly
position the bolt for travel. (F.)
13. Slide the mounting bracket fork
into the spool opening. Then thread
the 5/16”-18UNC x 31/2” long bolt into
the automatic feed lever until the
head of the bolt contacts the top of
the mounting bracket fork. (F.)
14. Operate the automatic feed lever
handle and observe the operation of
the indicator shaft. It should operate
smoothly between engaged and
disengaged positions. Adjustments
can be made by adjusting the length
of the bolt engaged into the automatic
feed lever. Once the adjustment is
complete, tighten the nut and lock
washer against the automatic feed
lever to lock in place. (F.)
