OIL CHANGE
An oil change is required every 2000 hours of operation, or every six months whichever occurs first.
Where operating conditions are severe, such as rapid rise and fall in temperature of the indexer
housing (which is accompanied by sweating of the inside walls with a resulting formation of sludge),
where operation is in moist and dusty atmospheres, or in the presence of chemical fumes, it may be
necessary to change the oil in intervals of one to three months.
NOTE: The magnetic drain plug should be visually inspected at this time for
metallic chips that might indicate failure of one of the internal components.
TYPE OF OIL - For a copy of interchangeable industrial lubricants please call:
Lubricating oils should be high quality, well refined petroleum oils or synthethic lubricants with extreme pressure
additives. They may be subjected to high operating temperatures, so the y must have good resistance to oxida-
tion. These oils should meet the American Gear Manufactures Association (AGMA) standards, AGMA 4EP or
AGMA 5 EP.
Change the oil every 2000 hours of operation, or every six months whichever occurs first.
The following is a list of CAMCO approved lubricants for use in CAMCO Index Drives.
MOBILGEAR 630
(Mobil Oil)
OMALA 220 (Shell Oil)
SERVO INDEXER (SHC 634)
NOTE: When the gear reducer and Index Drive have common oil as in the case of the 902RDM
Index Drive with the R250 reducer, an AGMA #8 compound is recommended.
One such lubricant is Mobil's 600 W SUPER CYLINDER OIL.
* If you cannot locate the oil listed your supplier should be able to cross reference
to another brand.
For SCI
(Servo-controlled Indexing) Indexers, use MOBIL SHC 634.
NOTE: For lubricants used in Gear Reducers not sharing common oil with Index Drives see the
GEAR REDUCER SERVICE SECTION.
GREASE PACKED BEARINGS
Bearings that are accessed by oil in the indexer reservoir require no additional maintenance. Bear-
ings not lubricated by the oil in this way are normally packed with a high quality bearing grease.
However, bearings that are not lubricated by the oil reservoir or by grease packing will require
periodic greasing. Bearings of this type will be furnished with a grease fitting and should be
greased with NGLI #3 bearing grease at least once per month. Do not overlube since the excess
grease will eventually fall into the indexer oil reservoir.
INSPECTION OF CAM FOLLOWERS
The Cam followers should be inspected every 8000 hours of operation. Backlash at any station
indicates worn or damaged cam followers. Any binding on rotation of the input shaft is an indication of
broken cam followers.
To inspect for excessive backlash, place the indexer in a dwell position and check for looseness by
physically trying to force the dial or crank arm back and forth. If excessive looseness is found (.0015
at 6" radius) this indicates that replacement of the cam followers is required and the Index Drive
should be returned to CAMCO for repair.
Contact your nearest CAMCO representative for assistance if necessary.
