I.Reading Exercises:
Exercise 1. Read and memorize using a dictionary:
elevated drive sprocket; improve durability; ease of maintenance;more powerful; horsepower; drivetrain; small machine ; old lawnmower parts; high-drive system; high drive; design; the final drive system; small gear ; multiple gear teeth ; permanently lubricated track system; medium-size bulldozers; upgraded version ; ground surface rock .
Exercise 2. Answer the questions:
Why was the Caterpillar D10 needed?
What bulldozers were more powerful than the D9?
What is the disadvantage of the D10?
Where can the D11 be used?
Exercise 3. Match the left part with the right:
1) The Caterpillar D10 is |
a) large conventional bulldozers. |
2) The disadvantage is |
b) a track-type tractor manufactured by Caterpillar Inc. |
3) This machine used a high-drive system |
c) that the track moves around one more sprocket, reducing track life |
4) The Caterpillar D11 series of tracked-type tractors are |
d) with a sprung lower roller system |
Exercise 4.Open brackets choosing the right words:
As the engine and drivetrain are (fitted/mounted) high in a traditional bulldozer, the half shafts from the differential exit (under/above) the drive sprocket, (requiring/allowing) a small gear on the end of the half shaft and another, larger one (attached/detached) to the driven sprocket.
