This service and parts manual contains general information, operation, and maintenance information for Market Forge
modular kettles. A parts list is included in which each replaceable part is identified and shown in an accompanying
drawing. Accessories for use with the kettles are also described.
1.1 DESCRIPTION
Market Forge Kettles include both stationary and tilting
steam jacketed kettles of five capacities, each mounted
in a modular stainless steel cabinet.
Double wall construction around the lower half of the
kettle forms a surrounding chamber into which steam is
introduced as a source of heat for cooking.
Steam input plumbing is equipped with a manual control
valve. Condensate is removed through a steam trap
connecting with the kettle drain plumbing assembly. A
swivel spout, hot-cold combination faucet provides a
source of water for addition to the kettle for cooking and
cleaning.
An optional 12" spacer unit with faucet and sink may be
used instead of the standard built-in faucet.
1.1.1 5 Gallon Tilting Kettle
The 5-gallon 191itre capacity kettle is mounted in a
trunnion assembly to the modular cabinet top. The
trunnion pivots include steam input and return
connections for the kettle.
1.1.2 10-,25-,40-, & 60-Gallon
Stationary Kettles
These units include large capacity kettles mounted in
fixed position in modular cabinet bases. A counterbalanced, hinged lid covers the kettle openings.
Each is plumbed for direct connection to a remote steam
source. An optional cold water circuit to the steam jacket
is available for use with all models for quick cooling of
foods after cooking. See paragraph 1.1.4.

1.1.4 25- & 40-Gallon Chill Kettles
The chill kettle is a modified application of the stationary
models equipped with a built-in sink completely
surrounding the kettle. The kettle functions to instantly
suspend cooking by allowing kettle interior to be flooded
with cold water. Hot cooking water rises over the rim and
into the sink.
A further modification is the addition of a jacket cooling
system consisting of a cold water plumbing assembly
connected to the kettle jacket. The system is used in
conjunction with kettle flooding to rapidly cool the kettle
by allowing cold water to fill the steam jacket.

be removed by use of the Draw-Off Valve as
explained in step 11 for stationary kettles.
13. Complete cleaning procedures
(See paragraph 2.4.2).
2.4 CLEANING PROCEDURE
As with cleaning food soil from any cookware, an
important part of kettle cleaning is to prevent foods from
drying on. For this reason cleaning should be completed
immediately after cooked foods are removed. If time can
not be allotted for immediate complete cleaning the
kettle should be soaked by filling it with warm detergent
water solution.
2.4.1 Cleaning 5 Gallon Tilting Kettle
1. Wash the kettle with a nylon bristle kettle brush
(Part No. 10-5309).
2. Place Splash Shield in Sink with shield in front and tilt

not be installed until needed for removing food from the
kettles. To Insure correct operation and to prevent spills
the support must be securely installed as shown in Figure
2-1 and as explained below:
1. Hold the pan support in front of the upright as
shown at A.
2. Place the stud of the left-hand support upright into the
hole in the left side of the pan support. Then push the
right side of the support in until it engages the springloaded pin of the right-hand support upright, shown
at B.
3. Rotate the pan support upward (C) and engage the
slotted ends of the support links in the studs at the
base of eact support upright as in D.

SECTION 3 MAINTENANCE
WARNING:
DO NOT HOSE DOWN UNIT AS IT
CONTAINS ELECTRICAL COMPONENTS.
3.1 GENERAL
This section contains both preventive and corrective
maintenance information. Preventive maintenance may
be performed by maintenance personnel at the
establishment in which the kettle is installed.
It is recommended that user personnel never attempt to
make repairs or replacements to the equipment without
the assistance of authorized service. Assistance in
service methods or, a current Directory of Authorized
Service Agencies may be obtained from Market Forge.
(See Subsection 1.2).
3.2 PREVENTIVE MAINTENANCE
The most important preventive maintenance operation on
the steam jacketed kettle is the cleaning procedure after
each use described in Section 2. Additional preventive
maintenance operations are presented in this section.
or the steam supply which heats the kettle. While
mechanical problems are obvious faults of the kettle, any
deficiencies in volume and pressure of steam should be
traced to the steam generator and the cause determined.
Steam input requirements are listed in Appendix A,
Modular Kettle Steam Requirements. Additional
information may be found in separate service
publications for steam generators.
3.3.1 Lid Counterbalance Adjustment
The kettle lid is equipped with a torsion spring
counterbalance device to assist in lid lifting and to
prevent slamming. The device is shown assembled in
Figure 3-1 and exploded in Figure 4-11. If lid slams
closed when handle is released, spring tension should be
increased. If lid lifts up or refuses to remain down on
kettle, tension should be reduced. To adjust spring
tension proceed as follows:
1. Loosen 1/4" jam nut.
2. Adjust spring tension by turning 1/4" hex head cap
screw. Tighten to increase tension; loosen to reduce
tension.
3.2.1 Cleaning
A policy should be faithfully observed of completing, by
the end of each day's operation, all kettle cleaning
procedures explained in Subsection 2.4.
In addition, cabinet doors, top, fixtures, kettle lid, etc.,
should be washed and rinsed to remove all food spills.
For Chill Kettles, extra care must be given to cleaning the
sink surrounding the kettle. Pan support should be
removed as described in Subsection 2.5 and washed in a
sink.
3.2.2 Tilting Mechanism Lubrication
Lubrication of the tilting mechanism of 25-, 40- and
60-gallon tilting kettles is the only required preventive
maintenance other than daily cleaning. Inspect the screw
of the tilting mechanism annually for adequate
lubrication.
Should screw appear "dry" apply a good grade of ball
bearing grease directly on the threads so that the threads
appear to be barely damp. If mechanism fails to run
smoothly (see paragraph 3.3.5.).
3. Operate lid several times, repeating, step 2 until
desired operation is obtained.
4. Hold hex head screw firmly in position and
tighten jam nut to lock adjustment.
3.3 REPAIR & REPLACEMENT
In the event that the kettle fails to operate correctly, the
difficulty should first be isolated to either the kettle itself

SECTION 3 MAINTENANCE
3.3.2 Cabinet Exterior Removal
Side and rear panels of all cabinets in which kettles are
mounted are easily removed without the use of tools.
Each panel is grasped at the bottom edge and pulled out
sharply to release it from the panel mounting brackets
Shown in Figure 4-17 (12).
Replacement is completed by pushing panel up under
cabinet top and pressing in at the bottom until panel
mounting brackets are engaged. Doors may be removed
to improve access to cabinet interior for repairs as shown
In Figure 4-18.
The two flat head screws (10) and nuts (12) holding
cabinet hinge (11) are removed and the door lifted out.
When doors are remounted the final tightened position of
hinge (11) determines the alignment of the door and must
be set with care.
3.3.3 5 Gallon Trunnion Mounted Kettle
Disassembly
Trunnion mounted kettles may be removed from the
cabinet top for replacement of packing and seals which
may become worn through use. The kettle mounting is
shown in Figure 4-2 and is disassembled as follows:
1. Disconnect both steam inlet and condensate return
plumbing connected to the pedestal inside the cabinet
base.
2. Remove the three 3/8" bolts (4) and lock-washers (3)
which fasten the kettle mount to the cabinet top. The
kettle and mount may now be lifted from the cabinet.
3. Remove the four Allen Head set screws under one
pedestal leg.
NOTE: It is not necessary to remove both pedestal
legs. All replaceable parts are exposed by removing
one leg.
4. Disassemble .packing components (1) by pulling free
leg from kettle. Replace worn parts as required.
CAUTION: Packing rings on both sides of the kettle
mount must be replaced each time mount is
disassembled to assure a leakproof seal.
5. Reassemble in reverse order.
3.3.4 Draw-O Valve Repair
An exploded view of the draw-off valve is shown in Figure
4-14. All parts are replaceable.
3.3.4.1 Common Leak Repairs: To repair a valve leak, the
source must first be determined. Leaks from around the
valve stem are corrected by replacing the rubber "0" ring
(5) .Dripping from the valve outlet which occurs with the
valve tightly closed indicates faulty seating of the valve
disc (part of 6) against the valve seat. Dripping is often
corrected by cleaning residue from disc and seat using
very fine emery.
3.3.4.2 Valve Seat Lapping: Should either the disc (part of 6)
, or seat be found damaged it is necessaryb to either
replace the entire valve or perform the lapping procedure
as follows:
1. Disassemble the valve and clean both the disc and the
valve seat.
2. Attach the handle (2) to the stem with the valve bonnet
(4) removed.
3. Apply a good grade of fine lapping compound to the
disc and insert it into the valve to make light contact
against the seat.
4. Rotate the stem disc against the seat by turning the
handle, allowing the stem to wobble in the space the
bonnet would normally occupy. Continue with light
pressure until compound dries.
5. Reassemble and test for leaks with valve closed. If
dripping occurs repeat the lapping procedure as many
times as required to obtain a watertight seal.
3.3.5 Tilting Mechanism Repair
Tilting kettles are equipped with tilting mechanisms
shown in Figure 4-7 for 25- and 40- gallon kettles and
Figure 4-9 for 60-gallon kettles. Though both .utilize the
same screw assembly (2) , only Figure 4-7 includes
brake disassembly detail and serves as the reference
view for tilting mechan- ism repairs which follow.
3.3.5.1 Saginaw Screw Assembly Removal: The assembly is
removed with the kettle in the lowered position. Proceed
as follows:
3-2
Page 11
SECTION 3 MAINTENANCE
1. Remove the two bolts (8) which hold the ball nut
assembly in the screw lever (7).
2. Remove the two 5/16" hex head cap screws (13)
which fasten the screw housing (14) to the cabinet frame
(not shown).
3. Lift screw assembly from the cabinet.
Proceed in reverse order to replace the assembly.
3.3.5.2 General Inspection and Cleaning: The screw
assembly should run smoothly throughout the entire
stroke. If operation is not uniform remove the screw
assembly (paragraph 3.3.5.1) and proceed as follows:
1. Inspect screw shaft for signs of accumulation of foreign
matter in the ball grooves.
2. Using cleaning fluid or solvent remove dirt from ball
grooves. Be sure to flush the ball nut assembly
thoroughly.
3. Cycle the ball nut along the screw shaft several times.
Wipe with a dry lintless cloth and lubricate
immediately. (See lubrication 3.2.2).
4. If assembly continues to operate erratically after
cleaning disassemble and inspect the ball nut
assembly.
3.3.5.3 Ball Nut Disassembly: The Saginaw Screw is a ball
bearing screw power transmission device which converts
the turning motion applied by the hand crank ( 1) into
bi-directional force against the screw lever (7).
The frictionless "easy" transfer results from the use of
bearing balls circulated be- tween the screw and nut in
concave helical grooves. As the screw rotates inside the
nut, the bearing balls are directed from one end and
carried by a ball guide to the opposite end of the ball nut.
Figure 3-2 shows a cut-away view of the ball nut.
Figure 3-2
Ball Nut Assembly
3-3
Page 12
SECTION 3 MAINTENANCE
Nut disassembly requires extreme care in handling to
avoid loss of bearing balls and other small parts. The
Saginaw Screw must be removed from the kettle
(par.3.3.5.1) and the procedure completed over a clean
work surface. A small clean container and clean cloth are
required.
1. Place a clean cloth on the work surface with edges
gathered to form a pocket to retain the bearing balls.
2. Place the Ball Nut Assembly over the pocket and
remove the two Clamp Screws and the Guide Clamp.
3. Remove both halves of theGuidesimultaneously to
prevent distortion of either half.
4. Catch all the Balls on the cloth by slowly rotating the
Ball Nut on the screw. Place all balls in a small
container.Take an accurate ball count and record.
CAUTION
Every bearing ball is required for reassembly. Exercise
care in handling to avoid loss.
5. Remove the stop collar (5) held by set screw (3) at the
free end of the screw shown in Figure 4-7.
6. Slide the Ball Nut off the free end of the screw.
3.3.5.4 Ball Nut Inspection: Disassembly of the ball nut
must be completed to permit inspection (See par.
3.3.5.3). A Ball Bearing Replacement Kit containing
bearing balls and ball guide is available from Market
Forge parts distributors. Should the ball nut show
excessive wear I the entire Saginaw Screw assembly
must be replaced. Inspect components for wear points:
a. Balls. Check a random sample of 20 balls for
signs of scuffing or fish scaling. Diameter
variation between balls and trueroundness of
each one must be within .0001 inch. Balls which
fail to meet these requirements should be
replaced using the Ball Bearing Replacement Kit.
b. Guide. Inspect the pick-up fingers which consist
of short extensions at the end of each half guide.
Minor burrs can be removed and the guide
reused. If a ball impression appears on the finger
tips or the halves were distorted during removal,
the guide must be replaced.
c. Ball Nut. Inspect the internal threads of the ball
nut for signs of excessive wear, pitting, gouges,
corrosion or spalling in the ball groove area. If
these flaws are detected, the entire Saginaw
Screw assembly should be replaced.
3.3.5.5 Ball Nut Reassembly and Bearing Replacement: With
the ball nut disassembled (par. 3.3.5.3) complete the
following reassembly, using either existing bearing balls
or substituting a Ball Bearing Replacement Kit (part
number 91-1490).
1. Clean all ball nut components with a commercial
solvent and dry thoroughly before reassembly.
2. Slide the ball.nut onto the free end of the screw, round
nut end first, as shown in Figure 4-7.
3. Replace the stop collar (5) , Figure 4-7.
CAUTION
Bearing Balls are retained in the ball nut only when it is
mounted on the screw. To prevent the nut from
accidentally spinning off the screw the stop collar (or
other obstruction) must be placed on the free end.
4. Center the ball nut grooves on the shaft grooves by
inserting a cylindrical object (a drill bit shank, or other
object of same diameter as bearing balls), into the ball
nut return circuit hole. Carefully withdraw, taking care not
to disturb nut-to-screw alignment.
5. Insert bearing balls into the guide opening using slight
rotation of the screw to help feed them into the grooves.
Place remaining balls into one half of the return guide.
NOTE
If a Ball Replacement Kit is to be installed, first count out
the same number of new bearing balls as the number of
worn balls being replaced. DO NOT try to add extra balls.
There must be some free space in the circuit so that balls
will roll and not skid.
6. Place a dab of bearing grease at each end of the
half return guide to hold balls in place. Place the
mating half return guide over the half filled with balls
and insert the two ends of the ball guide into the
holes in the ball nut. Seat by tapping gently with a
rawhide or plastic mallet.
7. Inspect for free movement of the ball nut along the
entire stroke. There should be no binding, squeal, or
roughness at any point.
8. Place guide clamp in position and secure with
clamp screws.

SECTION 3 MAINTENANCE
3.3.5.6 Crank Sleeve Replacement: The driving end of the
Saginaw Screw (2) is formed into a slotted sleeve which
receives the engagement pins of the removable hand
crank (1 ). A worn or chipped sleeve which causes the
hand crank to slip out of engagement during kettle tilting
can be repaired with a Crank Sleeve Replacement Kit
(part number 91-2155).
The Saginaw Screw assembly must be removed from the
kettle to complete kit installation, (par. 3.3.5.1). The collar
(next to the ratchet wheel, Fig. 4-7) is removed by driving
out the roll pin which secures it to the screw shaft. The
replacement sleeve is slid over the faulty shaft end and
fastened with a roll pin. The repair is completed by
re-mounting the Saginaw Screw assembly.
3.3.5.7 Brake Mechanism Disassembly and Repair: The brake
mechanism, shown exploded in Figure 4-7, functions as
an anti-coast device for the Saginaw Screw.
When the hand crank (1) is turned clockwise (kettle
raising) , a ratchet wheel turns freely inside the ratchet
stop. Any "free wheeling" counter clockwise screw motion
is prevented by engagement of ratchet wheel teeth in the
stop and the drag of friction between the shaft collar, and
the ratchet wheel face. Additional torque applied by the
hand crank, as in kettle lowering, over-powers the drag
and allows the screw to turn with only mild resistance.
Failure of the brake mechanism to function as described
requires removal of the Saginaw Screw assembly (per
3.3.5.1) and disassembly of the brake for cleaning.
1. Remove the shaft collar at the crank sleeve end by
driving out the roll pin and sliding the collar off.
2. Slide the ratchet wheel off and inspect fol cleanliness. Use fine energy to remove an, build-up of
soil or glaze on facings.
3. Thoroughly clean all brake mechanisn parts of dirt
and lubricant.
4. Reassemble the mechanism taking care tha ratchet
wheel is facing correctly. Replace, the Saginaw
Screw assembly in the kettle cabinet.
