Honing Procedure Buick Park Avenue II рестайлинг

Mechanical ~342 words
  1. Follow the manufacturer's recommendations for use, cleaning, and lubrication when honing the cylinders. Use only clean, sharp stones of the proper grade for the amount of material to be removed. Dull, dirty stones cut unevenly and generate excessive heat. When using coarse or medium-grade stones, leave sufficient metal so all stone marks may be removed with the fine stones used for finishing to provide the proper clearance.
  2. During the honing operation, thoroughly clean the cylinder bore. Check for the correct piston fit.
  3. Make full strokes in the cylinder to eliminate taper. Repeatedly check the measurement at the top, the middle, and the bottom of the cylinder bore. NOTE: Handle the pistons with careful. Do not force the pistons through the cylinder until you hone the cylinder to the correct size. The piston can be distorted through careless handling. IMPORTANT: The finish marks should be clean but not sharp. The finish marks should be free from imbedded particles and torn or folded metal.
  4. When finish honing a cylinder bore to fit a piston, move the hone up and down at a sufficient speed to obtain a fine and uniform surface finish in a cross hatch pattern.
  5. Determine the finish hone cylinder measurement by measuring the piston to be installed, and by adding the average of the clearance specification. Measure the block and the piston at normal room temperature.
  6. True up the refinished cylinder bores. Final hone each cylinder bore to remove all stone or cutter marks.
  7. After final honing and before the piston is checked for fit, clean the bores with hot water and detergent. Scrub the bores with a stiff bristle brush and rinse the bores thoroughly with hot water. Do not allow any abrasive material to remain in the cylinder bores. This abrasive material will wear the new rings, the cylinder bores, and the bearings lubricated by the contaminated oil. After washing dry the bore.
  8. Permanently mark the piston for the cylinder to which the piston has been fitted.
  9. Apply clean engine oil to each bore to prevent rusting.
