Heavy Duty Mechanic – Block E Study Guide (Advanced Systems & Diagnostics
Review)
(T/F) An undercarriage system must provide a balance between adequate traction, machine
stability and satisfactory load carrying capacity - correct answer ✔✔True
The load carrying capacity of an undercarriage is determined mostly by the:
a) Height of the grouser
b) Weight of the machine
c) Width of each track shoe
d) Number of carrier rollers - correct answer ✔✔c) Width of each track shoe
(T/F) The stability of the machine is more important when the machine is an excavator rather
than a crawler tractor equipped dozer - correct answer ✔✔True
A tracked crane is more suitable for:
a) lifting heavy loads which are quite a distance from the machine
b) digging into the side of a dirt pile
c) lifting heavy loads that are very near to the machine
d) pulling heavy loads of material that are located some distance from the machine - correct
answer ✔✔c) lifting heavy loads that are very near to the machine
Identify 6 major components that compromise a typical undercarriage system: - correct answer
✔✔- track frams
- pivot shaft and equalizer bar
- track chain
- track and carrier rollers
, - drive sprocket
- idlers
- track tension and recoil mechanisms
- protective devices (guards)
The following type(s) of track links are available for us as required by a specific track chain
application:
a) split master links
b) flush mount links
c) one-piece links
d) interlocking links
e) any of the above links can be used in track chains - correct answer ✔✔e) Any of the above
links could be used in track chains
A low mount final drive and drive sprocket system could be used on:
a) a crawler tractor
b) an excavator
c) a front end loader
d) a shovel
e) any of the above machines are correct - correct answer ✔✔e) any of the above machines are
correct
(T/F) Track tension and recoil mechanisms must be inspected, maintained and serviced only
after you have read the service information relating to these systems - correct answer ✔✔True
Track chain tension that is too tight can cause:
a) accelerated wear of the moving undercarriage components
