TIMESAVER LAPPING COMPOUNDS

PRECISION FINISH ON BEARING SURFACES

GUARANTEED NOT TO IMBED  -   WILL NOT CONTINUE TO CUT!

Please see Precision Finish Booklet (PDF)

Timesaver Lapping Compound does not contain emery, aluminum oxide, silicon-carbide or similar charging abrasives.
They are unconditionally guaranteed not to imbed into any metal surface.
Prepared in powder form, to be mixed with oil as used.
Timesaver first acts as an abrasive, then the particles diminish to a polish, and finally to inert material.
Directions for use in each can.

Product Data Sheet

Abrasive Grain Sizes In Timesaver Lapping Compounds

Timesaver Lapping Compounds are formulated to first act as an abrasive, then diminish to a polish and finally to inert material. Other ingredients in the compound conglomerate the fines to prevent imbedding in the metal being lapped.

All compounds have a range of particle sizes with most of the work being done by the largest particles.

The selection of the grade depends more upon the amount of metal to be removed than the finish because the abrasive breaks down to a finer and finer size and eventually to a polish material.

Soft Metal Lapping Compound
for
LAPPING BABBITT, BRASS, BRONZE
and ALUMINUM

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

SPLIT BEARINGS - Mix TIMESAVER COMPOUND with light or medium oil to the consistency of a thin paste and apply to the bearing halves. Add a little oil to the surfaces; also apply oil to the shaft. Both up cap - not too tightly, just so shaft can be easily turned by hand; then proceed to lap. At intervals add sufficient oil to the surfaces to prevent them form becoming dry. Take up on bearings gradually as high spots are removed, applying fresh compound when necessary.

SLEEVE BEARINGS - Fit bearings snugly to shaft. Apply TIMESAVER mixed with oil to bearing and shaft. Insert shaft and lap with a twisting motion, adding oil frequently until proper clearance is obtained. Flush out with diesel or Stoddard Solvent.

HOT BEARINGS - Mix a small amount of TIMESAVER with oil. The mixture must be very thin. Apply freely to bearings and shaft through oil holes. Rotate the shaft. Add the thin mixture until bearing is free. Then flush out with diesel or Stoddard Solvent.

GEARS - Mix TIMESAVER COMPOUND with oil proportions of about one part TIMESAVER to three or four parts of oil (by volume). The use of heavy oil is advisable as this procedure prevents the mixture from being thrown from the gears and wasted. Apply mixture sparingly either by pouring or with a paint brush. When gears run quietly, flush out with diesel oil or Stoddard Solvent.

TIMESAVER COMPOUND will not imbed into any metal surface and will not continue to cut.

Hard Metal Lapping Compound
for
LAPPING CAST IRON, STEEL and BRONZE

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 or 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 races should be held in place by bolting down with blocks. Relatively heavy brake loads should be applied to insure fi

CAST IRON BEARINGS - mix our Hard Metal Compound with light engine or cutting oil to the consistency of a thin paste. 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 compound if necessary. When a full bearing surface has been

CAUTION - Do not use Hard Metal Compound (GREEN Labeled 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.
