## Discrepancy

LIFTER BORES WERE SLEEVED (12 EA) NOTE: SLEEVES CAME LOOSE IN ALL HOLES (EXCEPT 2), ROTATING AND BLOCKING OIL PASSAGE. NO SAFETY PINS IN PLACE TO MAINTAIN SECURITY OF SLEEVES, NO OTHER MEANS OF HOLDING SLEEVES IN PLACE. ONLY THING THAT APPEARED TO HOLD SLEEVES WAS BURR, CREATED WHEN OIL HOLE WAS DRILLED, AND MAYBE DRAIN HOLE AT BOTTOM WAS BURRED.  (INTENDED TO HAVE AN INTERFERENCE FIT ONLY, BETWEEN  HOLE PREPAIRED FOR SLEEVE AND SLEEVE WAS OF VERY THIN WALL,  ALUMINUM SLEEVE MATERIAL HOLE FINISH SIZE IS 1.000 INCH, FOR LIFTER,  SLEEVE APPEARS TO HAVE APPROX 1.125 DIAMETER CREATING ONLY A .062 WALL THICKNESS.  NOT ENOUGH TO MAINTAIN SECURITY WITHOUT AID OF STABILIZING PIN OR (WELD IN PLACE) OR MEANS OF SAFETY.
