INTRODUCTION

This service manual pertains to the disassembly and assembly of CAMCO’s Miniature RGD Series Index Drives MODELS 40, 50, 70 & 80RGD/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.

For your convenience in identifying and ordering spare or replacement parts, a complete Bill of Materials is included in this manual.

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 facility . When in doubt, CAMCO recommends that CAMCO trained servicemen make the repairs.

WARNINGS AND CAUTIONS

Statements in this manual proceeded 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 complete 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.

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

3. Remove round access cover. This may be done by drilling a hole in the cover, threading in a sheet metal screw, and pulling with pliers.

REMOVAL OF OUTPUT SHAFT.

A. Rotate the input shaft until the output is in

dwell.

B. Remove all upper and lower output bearing

cartridge capscrews.

looseness. It should not exceed .001 inch.Do not confuse radial loosness with axial endplay . Endplay will be from .03 to .06 as a normal condition. If it exceeds .06 it may require follower replacement.

C. Remove the upper and lower output

cartridge capscrews.

NOTE: Keep the shims with the cartridge. You will

be asked to reinstall or replace with same shim thickness during assembly .

D. Pull the output bearing thru the cartridge

opening. It may be necessary to tap on the lower end of the output shaft with a soft faced hammer to drive the output shaft and bearing cup out.

INSPECTION OF CAM FOLLOWERS.

NOTE: Generally , followers are replaced as added

insurance against eventual failure.

REPLACEMENT OF CAM FOLLOWERS.

Follower replacement in the field is not recommended by CAMCO. All follower removal and replacement must be done at CAMCO. Simply follow “RETURN FOR REPAIR” instructions in the “General Service Manual”. CAMCO will provide quick turnaround on standard follower replacement or standard follower wheel/shaft assembly replacement.

This is due to the size of the followers and the tools required to properly remove and install without damage to the follower stud or follower wheel.

REMOVAL OF BEARINGS.

7. A. Remove the output bearing cones from the

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

Inspect followers for damage or radial

B. Remove any remaining output bearing from

the housing by the same method as described in step “A”.

8. INPUT SHAFT/CAM REMOV AL. 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 both 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 end of input shaft to drive the

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

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

E. Use a wheel puller to remove one bearing

cone from the input shaft.

F. Support the side of the cam where the

bearing was removed and press or drive the shaft through from the remaining bearing side. This will remove the remaining bearing and cam simultaneously.

9. Remove input bearing cups from the cartridges

with a wheel puller, by prying or by drilling and tapping for jack screws.

10. Press out all oil seals from both input and

output cartridges.

ASSEMBLY

PRIOR TO REASSEMBLY

Clean and deburr all parts before reassembly . Follow tightening torque and Loc-tite

recommendations as outlined in the General Service Manual.

1. Use an arbor press to press bearing cups

into input cartridges. Coat outside of cup and the cartridge bore with anti-sieze lubricant prior to pressing. Fill cavity of cartridges with bearing grease recommended in the “General Service Manual”.

ASSEMBLING INPUT SHAFT.

2. A. Use arbor to press cam onto shaft. Be sure

key is installed into shaft. Apply anti-seize lubricant on shaft and cam bore prior to

pressing. B. Center cam on shaft. C. Use an arbor to press bearing cones

ontoshaft. Coat shaft and bearing bore with

anti-sieze lubricant prior to pressing. D. Install the input cartridges. Be sure to install

the same exact shims or equivalent height

as removed during disassembly. 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 (1 to 2 inch ozs.) 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 the cartridge screws and rotate the

cartridge tops to the most rearward position attainable within the slots provided in the cartridges.

3. ASSEMBLING OUTPUT SHAFT A. Install bearing cones on the output shaft.

Coat the shaft and bore with an anti-sieze lubricant prior to installation. The bore of the bearing should be heated prior to pressing, if a heat gun is available. Tap in place.

B. Install the bearing cup in the lower output

bore of the housing. Coat bore and cup with anti-sieze lubricant and tap in place.

C. Position the cam so the dwell rib is facing

the output end of the housing. (Keyways facing rearward.)

D. Insert the output shaft/follower wheel

assembly into the housing. Be sure the followers straddle the dwell rib during insertion.

E. Install the upper output bearing cup in the

housing and the cup with anti-sieze lubricant and tap into place.

F. Install both lower and upper output cartridges

with the equivalent shim thickness removed in disassembly .

G. Tighten 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 are removed and endplay still exists.

SETTING THE CAM

4. CAUTION: This mechanism is designed to operate

with adjacent followers in close ontact 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 furthermove, 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 (using shims between

the housing and cartridge) until two adjacent followers are in full contact with the cam rib. (This will also require adjustment to the eccentric cartridges along with the 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.
