Maintenance Instructions
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 selfadjusting 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.
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.
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 (
grease to drain back into the rear
grease case.

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.
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

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

NOTE: Make certain machined
recess on adapter and lip on
adapter ange and machine
ange to be sure they are ush.
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 counterclockwise to advance boring bar
until pilot drill contacts the main. One
turn of the feed crank moves the
boring bar

/2”/DN40 or 2”/DN50
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.
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 manufactured 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.
