INTRODUCTION

This service manual pertains to the disassembly and assembly of CAMCO’s RGD/RGS Series Index Drive MODELS 350RGD/RGS, 500RGD/RGS & 600RGD/RGS.

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 all standard index drives, for special index drives,please supply serial#) 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 cam followers. 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 any 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.

BEFORE STARTING

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 of your “General Service Manual” before disassembling CAMCO

units. CAMCO recommends returning defective equipment for inspection and repair whenever possible. CAMCO uses Loctite™ to secure all screws and setscrews, If you encounter a fastener that is difficult to

remove, apply heat to the screw and remove while still warm.

DISASSEMBLY

1. Remove all accessory equipment such as clutches, reducers, sprockets, etc. If equipped with a CAMCO R250 Reducer see disassembly instruction pertaining to this reducer prior to removal from unit.

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

3. Remove the access cover .

4. REMOV AL OF OUTPUT SHAFT.

A. Rotate the input shaft until the output is in

dwell (Where the rotation of the input shaft does not effect the rotation of the output).

B. Remove all output bearing cartridge

capscrews.

C. Remove the output cartridge.

NOTE: Keep shims with the cartridge. You will be asked to reinstall or replace with same shim thickness during assembly .

D. Pull the shaft out through the cartridge

opening.

Fig.2 Inspecting Follower.

6. FOLLOWER REMOV AL. 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 slide 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 Removing output shaft.

5. INSPECTION OF CAM FOLLOWERS. 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 eventual failure.

Fig.3 Removing follower

Page 5

7. Check the follower holes for roundness. These holes may be worn out due to overloads. The holes should be round within .0005 to permit reuse of the follower wheel.

8. REMOV AL OF BEARINGS.

A. Remove the large output bearing cone from

the output shaft with a small diameter aluminum bar and a hammer. Place the bar against the protruding edge of the cone and tap with the hammer, working around the perimeter to prevent binding. Continue this until the cone is free of the shaft.

Fig.4 Removing bearing cone.

B. Remove the output bearing cups from the

cartridges and housing with puller, by prying or by drilling and tapping for jack screws.

9. INPUT SHAFT / CAM REMOVAL.

NOTE: The output shaft must be removed prior to input shaft removal.

A. Rotate the input shaft and inspect all parts

for wear or damage. Endplay in the input shaft is not permissible.

B. Match mark all input cartridges relative to

the housing. These must be reinstalled in the same side and position since they are eccentric.

C. Remove all input bearing cartridge

capscrews.

D. Tap on the end of the input shaft to drive the

opposite cartridge from the housing. Then drive the shaft in the opposite direction for removal of other cartridge.

NOTE: Keep shims with their respective cartridges. You will be asked to reinstall or replace with same shim thickness during assembly .

E. Use a wheel puller to remove the bearing

cones from the input shaft.

F. Remove the cam locknuts with a spanner

wrench, if applicable. Be sure to bend the washer locking tang away from the nut prior to removal.

G. Press the shaft through the hole previously

occupied by the input cartridge (removed in Step D). This will automatically remove the cam from the input shaft. The use of an arbor press is recommended but this procedure can be accomplished by driving the shaft through with a soft faced hammer.

Fig. 5 Pressing out shaft.

H. Remove cam through the access opening.

10. Remove the input bearing cups from the cartridges with a pulley puller, by prying or by drilling and tapping for jack screws.

ASSEMBLY

PRIOR TO REASSEMBLY

Clean and deburr all parts before reassembling Follow tightening torque and Loctite™

recommendations as outlined in the “General Service Manual”.

1. Use an arbor to press the bearing cups into the 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”.

2. ASSEMBLING INPUT SHAFT.

NOTE: Assembly of the cam and bearings to the input shaft must be done inside the housing.

A. Use arbor to press the cam onto shaft. Be

sure key is installed into shaft first. Apply anti-sieze lubricant to shaft and bore prior to pressing. The bore of the cam should be heated prior to pressing, if a heat gun is available.

B. Use a spanner wrench to install the cam

locknuts. Adjust nuts to center cam on shaft ( if applicable).

Page 6

C. Use an arbor to press bearing cones onto

shaft. Coat shaft and bearing bore with antisieze lubricant prior to pressing. The bore of the bearing should be heated prior to pressing, if a heat gun is available.

D. Install the input cartridges. Be sure to install

the same exact shims or equivalent height

as was removed in disassembly Step 1 1D. E. Line up match marks. F. Tighten cartridge mounting screws. G. 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 remachine the cartridges if all

shims have been removed and endplay still

exists. H. Loosen input cartridge screws and rotate

the cartridge top to the most rearward

position attainable within the slots provided

in the cartridge.

3. ASSEMBLING OUTPUT SHAFT. A. Install the bearings cones on the output

shaft. Coat the bore of the cone with an antisieze lubricant prior to installation. Tap in place.

B. Install new followers with an arbor press.

C. Install the setscrews. The cone point

setscrews lock into the “V” notch. The cup point setscrews lock against the flat. The oval point setscrews are used when only one flat is provided on the follower stud. Be sure to use Loctite thread locking liquid as recommended in the “General Service Manual”.

D. Use an arbor to press the bearing cup into

the housing. Coat the outside of the cup and the bore of the housing with an anti-sieze lubricant prior to pressing.

E. Insert the output shaft/follower wheel

assembly into the housing.

F. Install the output cartridge with the

equivalent shim thickness removed in

disassembly . G. Tighten cartridge mounting screws. H. If endplay exists, remove shims until there is

a small amount of drag from preloading the

bearings. In rare instances it may be

necessary to remachine the cartridges if all

shims have been removed and endplay still

exists.

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.6 Installing new followers.

Page 7

4. SETTING CAM.

CAUTION: This mechanism is designed to operate with adjacent followers in close contact along their entire width with the surface of the cam during the dwell period. Unless this condition is achieved by proper installation, the mechanism will not transmit its rated load, and furthermore, serious damage to the cam and output shaft will occur .

A. Place the cam in dwell (keyway facing

rearward).

B. Rotate the tops of both input cartridges

toward the output until the cam followers touch the cam.

C. Shift the cam axially until two adjacent

followers are in full contact with the cam rib. (This will also require adjustment of the eccentric input cartridges 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.

Fig.8 Centering cam

D. Apply “Prussian Blue” to entire cam track. E. 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 bluing pattern.

2) The follower is free at 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 id worn off the side 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 leading or exit edges of the cam ribs. If so this is an indication that the cam is not adjusted properly.

5) There should be no looseness in any dwell. If there is adjust the eccentric input cartridges to slightly preload the loosest dwell.

F. Tighten the locknuts and secure with Loctite

#242 as specified in the “General Service Manual”. If lockwashers are used on your model, bend the tangs over the nut to insure locking.

G. Tighten the input cartridge capscrews and

dowel the cartridges to the housing.

H. Double check for endplay in output shaft.

Endplay is not permissible in the output shaft.

5. Reinstall the access cover with a new gasket. To insure leakage it is recommended you also apply “General Electric Silicone Rubber RTV -6” to the housing and cover. CAUTION: If your access cover is plexiglass be sure not to over tighten or cracking will result.

6. Grease pack the main output bearing with lubricant specified in the “General Service Manual”.

7. Install new oil seals as described in the “General Service Manual”.

8. 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.
