Camshaft Front & Rear Bearing Reaming

  1. Insert suitable taper pilots (18G 123AB & 123AC) into center and rear bearings. Place suitable pilot (18G 123L) on arbor, followed by suitable cutter (18G 123E). Pass arbor through front bearing and pilot in center liner.
  2. Place suitable cutter (18G 123B) on arbor and push arbor through taper pilot on rear bearing. Secure cutters and pilots in respective positions making sure cutter locating pins are engaged in correct numbered hole in arbor.
  3. Cutter for front bearing will cut first with arbor piloting in center and rear bearings. Clean cuttings and filings away frequently during operation. Cutter for rear bearing will follow arbor piloting in front and center bearings. Make sure that all cuttings are cleared away before plain pilot is allowed to enter front bearing. When cut in rear bearing is finished, free cutters and remove arbor.
