INTRODUCTION

This service manual pertains to the disassembly and assembly of CAMCO’s RA Series Index Drive MODELS
400RA, 401RA,512RA, & 662RA.

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 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.

10. REMOVING SHAFT FROM OUTPUT
ASSEMBL Y.

To remove the output shaft from the cover it will

be necessary to use an arbor press and
push from the back side of the shaft using
caution not to damage the parts.

C. 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 cartridges.

NOTE: Keep shims with their respective cartridges

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

D. Remove the input shaft/cam assembly

through the large cartridge hole (does not
apply to 662RA see Step E).

E. The 662RA requires removal of the cam

locknuts while still in the housing and
pressing the shaft through the hole
previously occupied by the input cartridge
and removed in Step C. This will
automatically remove the bearing cone from
one end of 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. 4 Pressing out shaft.

11. REMOVAL OF BEARINGS.

A. Use a wheel puller to remove the cone

portion of bearing from the shaft.

B. Removal of the upper bearing cup from the

output cover will require light tapping on the
backside of the cup with a round aluminum
bar and a hammer working around the
perimeter as you tap to prevent binding.
Continue this procedure until the cup is free
of the cover.

C. Removal of the lower output bearing cup

from the output cover requires prying from
the backside or drilling and tapping of jack
screw holes or the use of a pulley puller.

12. INPUT SHAFT REMOVAL.

NOTE: The output shaft must be removed prior to

input shaft removal

A. Rotate the input shaft and inspect all parts

for damage. Endplay in the output shaft is
not permissaable.

B. Remove all input bearing cartridge

capscrews.

Fig. 5 Removing input shaft.

F. Remove cam through the output opening.

13. REMOV AL OF CAM FROM OUTPUT SHAFT
(400RA, 401RA AND 512RA)

A. Use a wheel puller to remove the bearing

cones from the input shaft.

B. Using a spanner wrench remove the cam

locknuts.
C. Remove the spacers from the shaft.
D. Use an arbor press to remove cam from

shaft, using caution not to damage parts.

14. 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 cartridge with
bearing grease recommended in the “General
Service Manual”.

2. ASSEMBLING INPUT SHAFT.

A. Use an arbor to press the cam into shaft.

Be sure key is installed into shaft first.
Apply anti-sieze lubricant to shaft and bore
prior to pressing.

B. Install spacers on both sides of the cam as

removed in disassembly Step 13C.

C. Use a spanner wrench to install the cam

locknuts. Adjust nut to center cam on shaft.

D. Use 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.

3. INST ALLING INPUT SHAFT INT O HOUSING.
(On the 662RA the prior assembly steps were
done inside the housing).

A. Slip the input/cam shaft assembly through

the large cartridge opening.

B. Install the input cartridges. Be sure to install

the same exact shims or equivalent height

as was removed in disassembly Step 12C.
C. Tighten cartridge mounting screws.
D. If endplay exists remove an equal amount of

shims from each side until there is a small

amount of drag from 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.

4. ASSEMBLY OF OUTPUT SHAFT.
A. Press bearing cups into cover. Coat the

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

B. Press bearing cone on the output end of the

shaft. Coat the outside of the shaft and the
bore of the bearing with anti-sieze lubricant
prior to pressing. Heat up the bearing prior
to pressing if a heat gun is available.
