INTRODUCTION
This service manual pertains to the disassembly and assembly of CAMCO’s RDM Series Index Drives models
80RDM, 601RDM, 902RDM, 1305RDM, & 1800RDM.
The manual is to be used in conjunction with the General Service Manual which describes the lubrication and
general maintenance of CAMCO Index Drives.
An exploded view of your specific Index Drive is included in this manual. Also included is a complete Bill of
Materials for your convenience in identifying and ordering spare or replacement parts.
Some users of Index Drives have the facilities and trained personnel to accomplish service repair. You must
determine the extent to which intricate servicing should be done in your own facility. When in doubt, CAMCO
recommends that CAMCO trained servicemen make the repairs.
WARNINGS AND CAUTIONS
Statements in this manual preceded by the words WARNING or CAUTION and printed in italics are very
important. We recommend you take special notice of these during service or repair.
WARNING
Means there is the possibility of personal injury to yourself or others.
CAUTION
Means there is the possibility of damage to the CAMCO unit.
OIL SEAL REMOVAL
The only repair possible without disassembly of the indexer is replacement of oil seals. To remove oil seals, drill
a number of holes into the case of the seal. The seal may then be removed with a pointed tool. Be sure to
remove all metallic chips created during the drilling of removal holes. A new seal may be installed as outlined in
the “Oil Seal Installation Recommendations” section of the “General Service Manual”.
SPARE PARTS KIT
CAMCO offers a Spare Parts Kit for all CAMCO index drive models CAMCO builds. These kits include oil seals,
bearings, shims and miscellaneous haqrdware. Camfollowers are sold seperately . These are components that
will most likely require replacement during repair of your index drive. CAMCO recommends a Spare Parts Kit
be purchased and kept on hand prior to the disassembly of your CAMCO drive.
A compete list of components supplied in the Spare Parts Kit can be found in the parts list located in the rear of
this manual. The asterisk behind the item number indicates those parts supplied with the Spare Parts Kit.

6. FOLLOWER REMOV AL.
Followers can be removed at this stage.
A. Remove the setscrews. Apply heat to the
setscrews holding the follower studs and
remove while still warm.
B. Threaded holes have been provided in the
ends of the follower for ease of removal.
Use a slide hammer or a simple self-made
pull tool. The self-made pull tool consists of
a short piece of round tubing, large enough
to clear the follower diameter and a small
flat bar with a clearance hole large enough
to insert a capscrew of equal thread size as
the follower pull hole. Slip the tube over the
follower, place the bar over the tube and
thread a capscrew into the follower.
Tightening the capscrew will remove the
follower.
Fig.1 Output shaft removal
5. FOLLOWER INSPECTION.
Inspect followers for damage or radial looseness. It
should not exceed .001 inch. Do not confuse radial
looseness with axial endplay . Endplay will be from
.03” to .06” as a normal condition. If it exceeds .06
it may require replacement.
NOTE: Generally , followers are replaced as added
insurance against failure later.

cartridges. Coat the outside of the cup and the
bore of the cartridge with an anti-seize lubricant
prior to pressing. Fill cavity of cartridges with
bearing grease recommended in the “General
Service Manual”.
Fig.7. Centering cam on shaft
C. Use an arbor to press bearing cones onto
shaft. Coat shaft and bearing bore with antisieze lubricant prior to pressing. If a heat
gun is available it is recommended that the
bore of the bearing be heated prior to
pressing.
D. Install the input cartridges. Be sure to install
the same exact shims or equivalent height
as was removed in disassembly Step 9C.
E. Tighten cartridge mounting screws.
F.If endplay exists remove an equal amount of
shims from each side until there is a small
amount of drag from preloading the
bearings. In rare instances it may be
necessary to re-machine the cartridges if all
shims have been removed and endplay still
exists.
3. ASSEMBLING OUTPUT SHAFT.
A. Install the large bearing cones on the output
shaft. Coat the bore of the cone with an antisieze lubricant prior to installation. Tap in
place with a hammer and aluminum bar.

B. Install the bearing retainer capscrews and
washers. Use torque and Loc-Tite
recommendations from the “General
Service Manual”.
C. Install new followers with an arbor press.
CAUTION: Be sure to press the followers in straight
as damage to the follower and wheel could occur if
improperly aligned during installation. Be sure that
the notches are aligned with the setscrew holes.
Fig. 8 Pressing in new followers
D. Install the setscrews with double-notch
followers, the cone point setscrews lock into
the “V” notch. The cup point setscrews lock
against the flat single-notch followers, use
an oval point setscrew. Be sure to use Loctite thread locking liquid as recommended in
the “General Service Manual”.
E. Coat the inside of the bearing retainer ring
and the outside of the main output bearing
with anti-sieze lubricant. Place the bearing
retainer ring over the output from the
topside of the output/follower wheel and tap,
alternating from side to side until the
retainer is fully seated on the bearing.
F. Replace the shims removed in disassembly
step 4C.
G. Place cam in dwell position, keyway pointing
rearward.
H. Insert output/follower wheel into housing
with dowel holes in housing in line with
retainer.
I. Loosely install the bearing retainer
capscrews.
J. Install only one of the dowel pins through the
retainer ring into the housing.
4. SETTING THE CAM.
CAUTION: This mechanism is designed to operate
with adjacent followers in close contact along their
entire width, unless this condition is achieved by
proper installation, the mechanism will not transmit
its rated load,and serious damage to the cam and
output shaft will occur.
A. Place the unit on end or its side so both the
output side and the bottom opening are
accessible.
B . Place the cam in dwell, keyway facing
rearward.
C. While pivoting on the one dowel pin, rotate
the output towards the input shaft as much
as the clearance holes for the mounting
capscrews will allow.
D. Shift the cam axially until two adjacent
followers are in full contact with the cam rib.
This will also require adjustment of the
output retaining ring along with axial
adjustment of the cam.
1) If there is a gap at the root of the
follower the cam should be shifted
toward the follower.
2) If there is a gap at the tip of the follower
the cam should be shifted away from the
follower.

E. Apply “Prussian Blue” to entire cam track.
F.Rotate the camshaft slowly with a small
handcrank to ensure that:
1) Both rollers are in contact with the cam
rib in dwell. Look for uniform blueing
pattern.
2) The follower is free when it is in the
center of the crossover track.
3) You do not encounter unusual
resistance in motion. The bluing pattern
should be fairly uniform from side to side
during motion. If a patch of bluing is
worn off the outside of the cam rib on
one side of the cam and not the other,
shift the cam a .002 to .005 inches in the
direction of the worn side. Do not
overshift the cam or knocking will occur.
4) The cam bluing should never be worn
off the lead-in or exit edges of the cam
ribs. This would indicate that the cam is
not adjusted properly.
5) There should be no looseness in any
dwell. If there is looseness adjust the
output bearing retainer to slightly
preload the loosest dwell.
G. Tighten the locknuts and secure with
Loc-Tite #242 as specified in the “General
Service Manual”. If lockwashers are used on
your model, bend the tangs over the nut to
insure locking.
H. Tighten the output retaining ring capscrews.
I.Drill and ream the remaining hole in the
output retaining ring to accept the next
larger dowel pin. Install new dowel.
8. REINST ALL THE BOTTOM COVER. Apply
“General Electric Silicone Rubber RTV -6” to the
sealing surfaces of the housing and cover. Place
the gasket on the housing and place cover over
the gasket. Install and tighten capscrews.
9. GREASE P ACK THE MAIN OUTPUT BEARING
with lubricant specified in the “General Service
Manual”.
10. INSTALL NEW OIL SEALS as described in
the “General Service Manual”.
11. FILL THE INDEX WITH THE
RECOMMENDED OIL to level indicator . See
“General Service Manual”. Too high an oil level
will cause no damage. Too low a level may result
in unit failure.
