>Used carefully, the cylinder bore resizing hone, recommended tool C-823 or equivalent, equipped with 220 grit stones, is the best tool for this honing procedure. In addition to deglazing, it will
reduce taper and out-of-round as well as removing light scuffing, scoring or scratches. Usually a few strokes will clean up a bore and maintain the required limits.</ptxt></s1><s1

>Deglazing of the cylinder walls may be done using a cylinder surfacing hone, recommended tool C-3501 or equivalent, equipped with 280 grit stones, if the cylinder bore is straight and round. 20–60
strokes depending on the bore condition, will be sufficient to provide a satisfactory surface. Use a light honing oil. <emph
>Do not use engine or transmission oil, mineral spirits or kerosene.</emph> Inspect
cylinder walls after each 20 strokes. </ptxt></s1><s1

>Honing should be done by moving the hone up and down fast enough to get a cross-hatch pattern. When hone marks <emph
>intersect</emph> at 40-60 degrees, the cross hatch angle is most satisfactory
for proper seating of rings .</ptxt></s1><s1

> A controlled hone motor speed between 200–300 RPM is necessary to obtain the proper cross-hatch angle. The number of up and down strokes per minute can be regulated to get the desired 40–60
degree angle. Faster up and down strokes increase the cross-hatch angle.</ptxt></s1><s1

>Ensure all abrasives are removed from engine parts after honing. It is recommended that a solution of soap and hot water be used with a brush and the parts then thoroughly
dried. The bore can be considered clean when it can be wiped clean with a white cloth and cloth remains clean. Oil the bores after cleaning to prevent rusting.<symbol
