      A lot of mistakes on this video.
      1 revolution of the barrel = .025 not .25
      The 1/2 thousands numerical value is
      .0005 Not .005 (.005would be 5 thousands)

    Is a digital caliper a good substitute for a micrometer?

    • @vsvenson
      @vsvenson  4 года назад +1

      A substitute? No - a digital caliper really has a resolution down to 0.001" where a micrometer has a resolution down to 0.0001". But, hey, if it's all you have, a digital caliper is better than nothing!

    I have a question about the bolt , can I used the old bolts to torque the crank down? or I have to use new ones but then I can re-used them to stay in engine, in other words, if I use new bolts to torque them down to check clearance , I can reuse them again to assemble the engine

    • @vsvenson
      @vsvenson  4 года назад

      If you have new bolts, use the old ones to torque down for measurements and save the new ones for the final assembly. But, generally, the crank bearing cap bolts can be reused.

    I took my engine to a machine shop when he measured it he said the clearance I have it good maybe a little looser side within spec. But with plastigauge it's showing its too tight. Which would you side with?

    • @vsvenson
      @vsvenson  4 года назад +2

      I'd side with the shop. I also don't get very accurate measurements with with plastigauge - I think it's because you can't really put the plastigauge on all sides of the crankshaft at the same time. I bet the plastigauge is lifting up part of the crank, or maybe gravity is compressing it more, or it's somehow not sitting perfectly concentric in the bearing bore. But if you accurately measure both with real tools, then you have real numbers - not an approximation - to make a decision on the tolerances.

    Great video, thanks for the help! Only one thing I’d like to point out is, if it’s graduated in half thousandths, it would measure out to .0005. .005” is 5 thousandths. So do you mean each tick on the dial is 5 thousandths of an inch or five ten thousands of an inch (.0005 which would be half a thousandth)

    • @vsvenson
      @vsvenson  5 лет назад +1

      I may have misspoke... On the dial on the bore gauge, each tick is half a thousandth of an inch, or 0.0005"

    How do you purchase the correct bearings if you don’t have any?

    • @vsvenson
      @vsvenson  5 лет назад +1

      Once you know the size, you'll know if the standard ones will be within tolerance or if you need to have a machine shop grind the journals down for an "oversized" bearing.

      Plastigauge is a valid way to measure, but I've always found this method more precise. I've tried plastigauge on the same surfaces several times in a row and had small variations.

      a set of calipers are actually more inaccurate than a bore gauge
