WARNING

IT IS THE RESPONSIBILITY OF THE OPERATOR TO OBTAIN AND OBSERVE THE MANUFACTURERS MATERIAL SAFETY DATA SHEETS FOR CONSUMABLE MATERIALS INFORMATION SUCH AS, HAZARDOUS INGREDIENTS, PHYSICAL/CHEMICAL CHARACTERISTICS, FIRE, EXPLOSION, REACTIVITY, HEALTH HAZARD DATA, PRECAUTIONS FOR SAFE HANDLING, USE AND CONTROL MEASURES AND ALSO TO TAKE LOCAL REGUALTIONS INTO CONSIDERATION.

CAUTION

THE DIFFERENT PARTS OF EACH BEARING ARE NOT INTERCHANGEABLE AND MUST ALWAYS BE KEPT TOGETHER; BECAUSE BEARING FAILURE CAN OCCUR IF THE PARTS ARE MIXED.

Procedure

1. SUBTASK 70-53-02-630-001 Remove the Wax Protection from New Bearings

   1. Remove and discard the paper from around the bearing.

   2. 

      CAUTION

      DO NOT USE COMMERCIAL KEROSINE TO CLEAN THE BEARING.

      NOTE

      Keep the fluid at the correct temperature, all the time, to prevent contamination caused by water spray. When each 12 gal (45 l) of fluid has cleaned 100 bearings, drain and clean the tank. Then fill the tank with new fluid. This procedure must be done more frequently, if the fluid gets very dirty.

      Soak the bearing in the first fluid (made from 70 parts by volume of CoMat 10-037 ENGINE FUEL together with 30 parts by volume of CoMat 10-020 MINERAL OIL, at a temperature of 167 to 185 deg F (75 to 85 deg C). Soak the bearing until all the preservation material is removed.

   3. NOTE

      The second fluid is the same type as the first fluid, but the first fluid is replaced more frequently. When necessary, add new fluid to keep the tank at a constant level.

      Soak the bearing in the second fluid, at a temperature of 167 to 185 deg F (75 to 85 deg C), until it is clean. Drain the bearing for five minutes.

   4. NOTE

      Keep the oil at the correct temperature, all the time, to prevent contamination caused by water spray. If the oil cools, increase the temperature to the correct level for sufficient time to remove the water. When necessary, add new oil to keep the tank at a constant level.

      Soak the bearing in clean oil CoMat 10-039 ENGINE OIL, CoMat 10-040 LUBRICANT (ENGINE OIL) or CoMat 10-059 ENGINE LUBRICATING OIL, at 221 to 230 deg F (105 to 110 deg C). Drain the bearing, then let it cool.

   5. Put the cool bearing in to a clean bag, made from CoMat 12-002 POLYETHYLENE SHEET. Then close and seal the bag.

   6. NOTE

      This procedure will only give protection for a maximum of 14 days.

      If the bearing is not installed on the engine in less than 14 days, the bearing preservation procedure (Refer to the SPM TASK 70-53-01-620-501) must be done.

2. SUBTASK 70-53-02-630-002 Prepare the New Bearings which have Oil Protection

   1. Remove one corner of the Fromocene envelope and let the oil drain into a clean container.

   2. NOTE

      Do not remove the oil protection before a visual inspection of the bearing is made.

      If necessary, the bearing can stay in its envelope for a maximum of 14 days before it is installed, but always seal the envelope again.

   3. The bearing can be installed on the engine directly from its envelope or it can first be soaked in clean CoMat 10-039 ENGINE OIL, CoMat 10-040 LUBRICANT (ENGINE OIL) or CoMat 10-059 ENGINE LUBRICATING OIL.

3. SUBTASK 70-53-02-210-001 Inspection of the Bearings

   1. 

      CAUTION

      CLEAN POLYTHENE, PVC OR RUBBER GLOVES, MUST ALWAYS BE USED TO TOUCH THE BEARING DURING THE INSPECTION.

      

      CAUTION

      THE OIL PROTECTION, WHICH IS APPLIED AFTER THE BEARING IS CLEANED, MUST NOT BE REMOVED. THE OIL CONCENTRATION CAN BE DECREASED, IF SOME PARTS ARE CLEANED WITH A GLOVE (REFER TO CAUTION ABOVE), TO HELP WITH THE INSPECTION.

      

      CAUTION

      A BEARING, OR PART OF A BEARING, MUST NOT BECOME DRY. WHEN A BEARING IS CLEANED, THE INSPECTION AND PROTECTION THAT FOLLOW MUST ALWAYS BE PART OF A CONTINUOUS PROCEDURE. MAKE SURE THAT THE FULL PROTECTION IS COMPLETED.

      

      CAUTION

      A CLEAN LOCATION MUST ALWAYS BE USED FOR THE INSPECTION OF THE BEARINGS; WITH A MINIMUM TEMPERATURE OF 60 DEG F (15.5 DEG C) AND A MAXIMUM RELATIVE HUMIDITY OF 75 PERCENT.

      NOTE

      Magnification can be used, to find the type and dimension of a defect.

      A minimum magnification of 4X will help to examine tool steel roller parts.

      To make a visual inspection of the bearing, always use near vision; without magnification.

   2. After a visual inspection soak the bearing in clean CoMat 10-039 ENGINE OIL, CoMat 10-040 LUBRICANT (ENGINE OIL) or CoMat 10-059 ENGINE LUBRICATING OIL. Make sure that all the parts of the bearing have a layer of oil on them. Put the bearing in to a clean bag, made from CoMat 12-002 POLYETHYLENE SHEET; then close and seal the bag.

   3. NOTE

      This procedure will only give protection for a maximum of 14 days.

      If the bearing is not installed on the engine, in less than 14 days, the bearing preservation procedure (Refer to the SPM TASK 70-53-01-620-501) must be done.
