INTRODUCTION

This service manual pertains to the disassembly and assembly of CAMCO’s Heavy Duty "E" Series Index Drive models
950E, 1150E, 1550E & 2050E.

This manual is to be used in conjunction with the General Service Manual, which describes the lubrication and general
maintenance of CAMCO Index Drives.

A cross section view of a typical CAMCO Heavy Duty "E" Series Index Drive model 950E, 1150E, 1550E or 2050E is
included in this manual. Item numbers within this Service Manual refer to the cross section view. Also included is a
generic Bill of Materials for your convenience in identifying and ordering spare or replacement parts. Always provide
the serial number from the Index Drive when ordering spare or replacement parts.

Some users of Index Drives have facilities and trained personnel to accomplish service repair. You must determine the
extent to which intricate servicing should be done by your own maintenance personnel. When in doubt, CAMCO rec­ommends the assistance of a CAMCO trained serviceman when making repairs.

CAMCO suggests that it is best to completely remove all tooling from CAMCO's Heavy Duty "E" Series Index Drive
prior to completing repairs. Realistically, removing all tooling from CAMCO's Heavy Duty "E" Series Index Drive is pro­hibitive. Tooling should be removed only as necessary in order to complete one or more of the following four related
procedures. The degree of disassembly increases with the addition of each procedure.

1. Input Oil Seal Replacement

Usually all tooling can be left in place when replacing oil seals. Removal of some portions of the drive package might
be required. See the section titled "Oil Seal Replacement" in this Service Manual for complete details.

2. Cam Follower Replacement

If the machine builder has provided access to the cam follower screws, the tooling does not need to be removed. Cam
followers can be replaced through the side access cover and follower access cover. See the section titled "Cam
Follower Replacement" in this Service Manual for complete details.

3. Input Shaft and/or Cam Replacement

In most cases, the input shaft and cam can be removed without removing all tooling. A section of the support struc­ture and fixtures can be removed, or the support structure and fixtures can be lifted two to three feet above the unit
and supported by appropriate scaffolding. CAMCO recommends using professional machinery riggers for this pur­pose. The assistance of a CAMCO trained serviceman is recommended. See the section titled "Input Shaft and/or
Cam Replacement " in this Service Manual for complete details.

Follower Wheel and/or Output Bearing Replacement

In most cases, the follower wheel and/or output bearing cannot be removed without removing the major portion of any
support structure and fixtures. An overhead hoist, boom crane or similar device must be used to lift the follower wheel
and output bearing. In some cases, the support structure and fixtures can be lifted two to three feet above the unit and
supported by appropriate scaffolding. The follower wheel and output bearing can then be removed with a boom crane
or similar device. CAMCO recommends using professional machinery riggers for this purpose. The assistance of a
CAMCO trained serviceman is recommended. See the section "Follower Wheel and/or Output Bearing Replacement"
is this Service Manual for complete details.

WARNINGS AND CAUTIONS:

Statements in this manual proceeded by the words WARNING or CAUTION and printed in italics are very important.
CAMCO recommends you take special notice of these during service or repair.

WARNING

CAMCO’s Heavy Duty "E" Series Index Drives cannot be "hand cranked" when completely assembled, i.e. with follower
wheel installed. During some portions of repair, the motor drive package is used to rotate the input shaft and follower
wheel. Some means for running the motor at extremely low speeds is mandatory. Use extreme caution when operating
the motor during repairs.

Before starting disassembly of your CAMCO unit you should read and review the following instructions. These provide
important information on parts and procedures necessary to successfully complete your repair.

Comply with all WARNINGS and CAUTIONS!

Read the "Trouble Shooting Guide" section in your "General Service Manual" before disassembling CAMCO units.
CAMCO recommends the assistance of a CAMCO trained serviceman whenever repairs are more involved than replac­ing oil seals or cam followers.

TORQUE REQUIREMENTS FOR TIGHTENING SCREWS:

Values are for threads engaged 1.5 times the screw thread diameter and installed into steel parts.

DISASSEMBLY AND INSPECTION:

DISASSEMBLY:

1. Remove only those structural members
and fixtures required to gain access to
the index drive and to allow for complet­ing the necessary procedures.

2. Drain oil and flush with flushing solvent.
Retain any chips or broken pieces you
may find. These may aid in diagnosis.

2.1. Oil may be drained by removing
Magnetic Drain Plug (Item #23).

2.2. Alternatively, oil may be drained by
removing Cover (Item#7) and pumping
the oil from the unit's sump.

3. Remove socket head cap screws (Item #

27) and Cover (Item #6).

INSPECTION:

1. While slowly rotating input, inspect cam
(Item #4) surface to determine if cam must
be replaced. Inspect for a rough or rip­pled surface, gouge marks, pitting and
other imperfections.

WARNING

CAMCO's Heavy Duty "E" Series Index Drives
cannot be "hand cranked" when completely
assembled, i.e. with follower wheel installed.
During some portions of repair, the motor
drive package is used to rotate the input shaft
and follower wheel. Some means for running
the motor at extremely low speeds is manda­tory. Use extreme caution when operating the
motor during repairs.

2. Slowly index the unit and place the Index
Drive in a dwell position.

2.1. While manually applying torque to

the output follower wheel (Item #2),
check for pre-load in dwell. Try to
rotate the cam followers (Item #14)
that are in dwell.

2.2. Visually observe the surface of the
outer shell. Inspect followers for
damage or radial looseness.
Looseness should not exceed .001
inch. Do not confuse radial looseness
with axial endplay. End play will be
from .03 to .06 inch as a normal con­dition. If endplay exceeds .06 inch
the followers should be replaced.

NOTE: Generally, cam followers are replaced
as added insurance against later failure.
When in doubt, replace the cam followers.

3. Broken cam followers indicate possible
damage to the follower wheel. Remove
any broken cam followers. See the sec­tion titled "Cam Follower Replacement",
in this Service Manual. Inspect the cam
follower stud hole in the follower wheel
for damage, and to determine whether
the cam follower stud hole is "wallowed
out", elongated, oval, etc. Using the
nominal size of the cam follower stud as
a guide, verify a press fit between the
stud and the hole, -. 0005 to -. 0010 inch
for the full length of the hole.

4. Wobbling of the output or grinding noises
during each index indicate damage to
the output bearing (Item #5). Further
inspection requires removal of the follow­er wheel. See the section titled
"Follower Wheel and Output Bearing
Replacement" in this Service Manual.

5. Replace cam followers if loose in dwell or
if the outer shell is visibly damaged. See
the section titled "Cam Follower
Replacement" in this Service Manual.

6. Replace the cam if imperfections are
noted. See the section titled "Cam
and/or Input Shaft Replacement" in this
Service Manual.

7. Replace the follower wheel if holes are
oversized. See the section titled
"Follower Wheel and Output Bearing
Replacement" in this Service Manual.

OIL SEAL REPLACEMENT:

CAMCO recommends replacing the Input oil
seals (Item #13) anytime the input is disas­sembled regardless of whether they are dam­aged or not. After being in service for some
time, the sealing lip can become brittle and
easily cracked. Most damage to oil seals
occurs at assembly when recommended seal
installation procedures are not followed.

To replace the oil seal on the reducer side of
the index drive, remove the reducer and addi­tional drive equipment as necessary to gain
access to the seal. See the reducer and other
manufacturers’ Service Manuals for instruc­tions on removing this equipment. On the
other side of the index drive, remove visual
dwell indicator or other equipment as neces­sary to gain access to the oil seal.

OIL SEAL REMOVAL:

1. To remove the oil seal, use a sharp punch
and punch two (2) diametrically opposed
holes through the case of the seal. Install
sheet metal screws into the holes.

2. Use a Slide Hammer or Pliers (Vise Grips‚)
to grip the sheet metal screws to pull out
the existing seal.

CAUTION

Do not drill holes in the case of the seal.
Chips will get into the unit and they cannot be
easily removed. A punched hole provides a
better "bite" when installing sheet metal
screws into the metal case.

OIL SEAL INSTALLATION:

1. Check new seal for damage that may
have occurred prior to installation.

1.1. An oil seal with a sealing lip that is

turned back, cut or otherwise damaged
should be replaced and not used.

1.2. Likewise, if the outer face or outside

diameter is bent or otherwise dam­aged, replace the oil seal.

2. Check the input shaft for surface nicks,
burrs or a groove from the sealing lip.
Look for spiral machine marks that can
damage the seal lip.

2.1. An input shaft with a groove from the
sealing lip can be repaired with a
Chicago Rawhide Speedi-Sleeve‚ or
similar product from another manufac­turer. Consult the manufacturer for
installation instructions.

2.2. Alternatively, the input shaft could be
replaced instead of repaired.

3. Check the end of the input shaft and
remove any burrs or sharp edges. The
end of the shaft should be chamfered.

4. Check splines and keyways for burrs or
sharp edges.

5. Wrap the input shaft with plastic shim
stock as a temporary sleeve to guide and
protect the sealing lip.

6. Check the sealing lip direction. Make
sure the new seal faces the same direc­tion as the original. CAMCO's standard
practice is to mount the seal so the lip
faces the lubricant or fluid to be sealed.

7. Pre-lubricate the sealing element by wip­ing the surface with the lubricant being
retained. Apply a thin layer of "General
Electric Silicone Rubber RTV-6" or equiv­alent to the cartridge bore as a sealant.
When the seal in pressed into place, a
bead of sealant will form at the back edge
of the steel case and prevent any leakage
around the outside edge of the seal.

8. Whenever possible use an installation tool
that has been specifically manufactured
for installing the seal.

6

8.1. Installation tools should have an out­side diameter .010 inch smaller than
the bore size. The bore should be
.005 larger than the shaft size, and the
face of the tool should be relieved so
that pressure is applied only near the
outside diameter of the seal.

8.2. During installation press the seal
flush to the cartridge face to avoid
cocking the seal in the bore. This also
positions the seal correctly on the
shaft.

9. When an installation tool cannot be man­ufactured, install the seal by tapping uni­formly around the seal with a soft ham­mer. Avoid cocking the seal and make
sure the face of the seal is square to the
bore.

CAM FOLLOWER REPLACEMENT:

CAM FOLLOWER REMOVAL:

Instructions for replacing cam followers
assume the cam and follower wheel will not
be removed. If the follower wheel will be
removed, proceed to the section titled
"Follower Wheel and/or Output Bearing
Replacement" in this Service Manual.
Likewise, if the cam will be removed, proceed
to the section titled "Cam and/or Input Shaft
Replacement" in this Service Manual.
Otherwise, proceed with the following steps.

If the machine builder has provided access to
the cam follower screws, the tooling does not
have to be removed. Otherwise the support
structure and fixtures can be removed as nec­essary, or the support structure and fixtures
can be lifted two to three feet above the unit
and supported by appropriate scaffolding.
CAMCO recommends using professional
machinery riggers for this purpose. The
assistance of a CAMCO trained serviceman
is recommended.

At least three (3) hours before installing new

cam followers, pack all new cam followers in
a large Styrofoam container (Igloo‚ 50 or 60
gallon Ice Chest) three-quarters filled with dry
ice.

1. Remove socket head cap screws
(Item # 32) and remove side access
cover (Item #10)

2. Once this cover is removed you may
view inside to locate the follower access
cover (Item #9). Remove the socket head
cap screws (Item #25) and remove this
cover.

3. Use the motor and drive package to
rotate the input shaft and follower wheel
until a follower is positioned directly
above and centered on the removal
opening.

WARNING

CAMCO’s Heavy Duty "E" Series Index Drives
cannot be "hand cranked" when completely
assembled, i.e. with follower wheel installed.
During some portions of repair, the motor
drive package is used to rotate the input shaft
and follower wheel. Some means for running
the motor at extremely low speeds is manda­tory. Use extreme caution when operating the
motor during repairs.

4. Remove bore plug (Item #33), the cam
follower screw (Item #15) and the heavy
washer (Item #9). CAMCO used Red
Perma-Lok‚ to secure these screws If
you encounter difficulty when removing
the screw, apply heat to the screw and
remove while still warm.

CAUTION

Localized heat can distort the part. Do not
overheat any item.

5. Using a large soft faced hammer, drive
the cam follower downward and out
through the follower wheel.

6. Inspect each cam follower stud hole for
roundness and size. The cam follower
stud hole must be a interference fit. The
cam follower holes must be -.0005 to ­.0010 inch for the full length of the hole.
Check the follower holes for roundness.
These holes should be round within .0005
TIR of an inch to permit reuse of the
follower wheel. These holes may be
worn-out due to overloads.

CAUTION

Do not use a follower wheel with oversize fol­lower holes. The cam followers and cam will
fail prematurely.

CAM FOLLOWER INSTALLATION:

The instructions for replacing cam followers
assume the follower wheel and cam were not
removed. Cam followers will be installed one
at a time through the follower access hole in
the housing. If the follower wheel was
removed, proceed by repeating the first four
steps until all cam followers have been
installed in the follower wheel.

If the cam was removed but not the follower
wheel, proceed by repeating the first four
steps until all but two cam followers have
been replaced. Also see additional instruc­tions below.

WARNING

Use protective gloves while handling cam fol­lowers after they have been packed in dry ice.

1. Coat the follower wheel stud hole with
anti-seize lubricant. Using quick sure
movements, place a cam follower that
has been packed in dry ice for at least
three (3) hours into the follower wheel
hole.

1.1. Using a twisting motion of the hand,
push the cam follower upward hard
enough to press the cam follower into
the follower wheel hole. Make sure the
shoulder on the cam follower seats
against the follower wheel. Do not
rush the process; just proceed quickly
and with sure movements.

1.2. If the cam follower cannot be seated
by using a twisting motion of the hand
and pushing upward, use a soft faced
hammer to drive the cam follower into
the follower wheel.

1.3. Alternatively, pull the cam follower
into place using the cam follower
screw, heavy washer and tapped hole
in the cam follower stud.

1.4. In a worst case, place a steel plate
against the bottom of the cam follower
and use a hydraulic jack to push the
cam follower into the follower wheel.

CAUTION

Make sure the shoulder of the cam follower is
seated against the follower wheel and make
sure the follower is installed straight and in
line with the hole. Damage to the cam
follower, follower wheel or cam could occur if
cam follower is improperly aligned during
installation.
