Directions for Using TIMESAVER

Mix TIMESAVER with oil as you use it and only the amount needed for the particular job to be done.  Keep well mixed.

GEAR UNITS – Mix TIMESAVER with heavy oil or grease in proportions of one-part TIMESAVER to three parts of oil by volume.  It is preferred to protect ball or roller bearings by the use of shields of by covering with grease.  It is customary to leave the cover off of the gear case for convenient inspection and application of the lapping compound.  Bearing faces should be held in place by bolting down with blocks.  Relatively heavy brake loads should be applied to insure firm tooth contact and to speed the lapping action.  Apply the mixture across the face of the gear every few minutes, alternating with clean oil to insure that the mixture does not become dry or gummy.  Lapping speeds should be as fast as possible without throwing compound from the gears.  Occasionally check the lapping action by wiping off several gear teeth and noting the area of contact.  When the proper fit has been obtained, flush out the gear case with diesel oil or Stoddard Solvent.

CAST IRON BEARINGS – Mix our Hard Metal Compound with light engine or cutting oil to the consistency of thin past.  Mixture should be thick enough to stick to the bearings surface.  Just before placing the shaft in the bearing, add oil to surfaces in order to thin compound to proper lapping consistency.  Bolt up cap – not too tightly, just so shaft can be turned by hand – and proceed to lap.  At intervals add oil and take up on bearings gradual as high spots are removed, applying fresh compound if necessary.  When a full bearing surface has been obtained, tighten cap to final fit, add a few drops of oil and continue to lap for a short time before removing the broken down compound.  This operation produces the final finish and proper running clearance, which should NOT be changed or varied after bearing has been flushed out with diesel or Stoddard Solvent for final assembly. 

CAUTION –  Do not use Hard Metal Compound (GREEN Label Can) on Babbitt, brass, aluminum or bronze.  For this work, use our Soft Metal Compound (YELLOW Label Can).  TIMESAVER can be used on any hard metal friction surfaces where accurate fits are required, such as valve seats, machine tool ways, tool room applications etc.

TIMESAVER COMPOUNDS ABSOLUTELY DO NOT IMBED OR CHARGE INTO ANY METAL SURFACES.  Therefore, do not attempt to make a lead, copper or other soft metal lap to lap hard metals, as is done with emery, ground glass, silicon carbide or other similar charging abrasives.  The lapping plate should be at least as hard as the surface to be lapped and harder if possible.  The softer of the two metals will get the most wear.
