TM 5-3895-374-24-2 3.  LUBRICATION The bearings should be greased slightly approximately every 100 hours of operation with the recommended lubricant. NOTE Over greasing will cause the bearings to overheat 4. BEARING REMOVAL AND INSTALLATION The bearing cartridge assemblies which support the ends of the concentric shafts are made up of a flanged cartridge or housing and a roller bearing.  The bearing is a light press fit in the cartridge and can be installed or removed on an arbor press.  The bearing is bottomed against a flange of the cartridge with no shims or clearance allowance required. The bearing bore fits the concentric shaft loosely and this slide-on fit makes cartridge removal and installation easy. The   thrust   clearances   are   pre-established   by   factory   machining   and   no   shimming   or   adjusting   of   the   cartridge assembly to the housing is required at installation. The clearance in roller bearings is checked by pressing the top roller as far inward as possible and passing a feeler gauge  back  and  forth  between  it  and  the  outer  race.    If  this  is  done  when  the  vibrator  is  hot  from  operation  the clearance will more nearly reflect the actual operating condition. NOTE IMPORTANT It is absolutely necessary that the housing and all parts of the vibrator assembly be completely cleaned and kept free of dirt and contaminants in order to avoid rapid failure for new bearings.    If  there  is  a  probability  of  contamination,  Improved  working  conditions  should  be arranged before the job is attempted.  Solvents are recommended for cleaning and flushing. page 3 - 1288
