Questions and Answers

What is a key characteristic of a structural block engine design?

  • It is designed to serve as both the engine foundation and the tractor frame. (correct)
  • It uses dry sleeves to easily replace cylinder surfaces.
  • It is exclusively found in high-horsepower tractors.
  • It has cylinders that are not machined in the block casting.
  • Which type of cylinder block design features parent metal cylinders?

  • Wet sleeve design.
  • Sleeveless design. (correct)
  • Dry sleeve design.
  • Structural block design.
  • What is the primary benefit of using a dry sleeve cylinder block design?

  • The cylinder surface can be readily replaced without machining. (correct)
  • It is less expensive to manufacture than sleeveless designs.
  • It is not found in compact tractors, only large.
