  7. Replacing damaged rollers: Maintaining and repairing roller conveyors con- sists mainly of
  1. Indicator sag: When fabricating a jig, the millwright should minimize
  2. Airfoil: Air flows through the wheel with less turbulence in a cen- trifugal fan
  3. Blades of a cooling fan: Excessive build up of dirt on the used with an after cooler will create vibrations

  5. go around it: To obtain an object from the opposite side if the conveyor, you must
  6. First starts: Boundary lubrication usually occurs when a machine
  7. welded: Some chain links are easily removed and replaced; others have to be cut out and back into place
  8. A different direction: Each view of an orthographic projection show the shape of an object from
  9. reservior: When tracing a system, begin at the
  10. Equipment center line: Anchor bolts must be aligned to the
  11. You can feel a roughness as you rotate the shaft: If there are flat places in motor barrings,
  12. Shaft with the rotation shown: This symbol shows a
  1. The midpoint: When setting up dial indicators, the contact point pressure should be enough so that the stem is at of its travel range
  2. Compression: Taler-bored flange couplings are also known as cou- plings
  3. Plastic: The type of shim material that is used to support light weights and where the shims required are very thin is
  4. Metal to metal contact: When listening for unusual motor noises, you should be listening for
