Solutions to common cylinder honing problems

PROBLEM: Hone is not cutting

  • If stones are loading, you need to apply more honing oil to properly flush stones. We recommend our HO-10 Honing Oil. Filtered oil is preferred.
  • Make sure that your guide blocks are not too tight. Honing stones should contact the cylinder first. You should put the hone in the cylinder and then expand. The guide blocks should have about .010″ to .030″ clearance.
  • Try narrowing your stones, this will put more pressure on the abrasive. Use an old file or dressing stone to narrow the face of the hone stone. Along the entire length of the stone, take approximately 1/3 off the leading edge. This produces more effective pressure on the stone without changing the pressure setting of the hone.

PROBLEM: Hone is chattering

  • To eliminate chatter, try varying the stroke rate as you hone.
  • Try some of the tips listed above for troubleshooting if the “hone is not cutting” usually any of those suggestions will also help overcome chatter.

PROBLEM: Stones and guides are wearing unevenly

  • This is most commonly the result of light honing pressure. To remedy this problem, increase pressure and vary stroke rate momentarily.

PROBLEM: Taper in cylinders with limited access

  • Taper will develop while honing a cylinder that doesn’t permit equal overstroking at both ends. There is a tendency for the hone to dwell at the open end of the cylinder and remove too much material. Dwelling at the web end is not a solution because it removes too much material from the center and causes a barrel-shaped cylinder. Goodson offer special honing stones that prevent taper in these cylinders. They have shorter stones that exert more pressure at the bottom and are specially designed for use in short or blind holes. Please call our Techxperts for more information on these stones.

    Yes, chilled iron liners for racing, you need borazon stones to cut them, great lasting liners, use soft rings, about 200 grit finish.

    I have a 948 Austin Healey engine that has had cylinder liners put in at some point in its life. I had it bored .020 over by a local machine shop, and they say they can’t get a good hone on the cylinders because they think the liners are made of some kind of super hard metal. Therefore they think the rings will not seat properly.
    Have you ever heard of, or dealt with anything like this? Do you have any suggestions.
    Thanks
