Milton CAT 993K - Manual (Page 4)

• Proven components and high hour
rebuild and machine life standards
provide proven reliability
• Machine systems working together
in the harshest environments
• Diagnostic programs are available
to monitor machine health and
maintain uptime
MACHINE LIFE. The 993K is designed
to meet customer rebuild requirements
and a high hour structure life. This is
accomplished through design emphasis
put on key components:
Caterpillar Designed Components.
Components used to build Cat Wheel
Loaders are designed and manufactured
to Caterpillar quality standards to
ensure maximum performance even
in extreme operating conditions.
• Linkage. The 993K features the field
proven Z-bar linkage design with new
maintenance-free sleeve bearing (SB)
pins. A key benefit of the SB pins is
when maintenance is required, customers
can schedule change out of pins on a
planned maintenance day. Design of the
SB pins allows this planned downtime
due to the fact it has low risk of
consequential damage. In addition,
significant growth in width for support
of the Z-bar linkage further increases
strength and durability.
• Cat Planetary Power Shift
Transmission. The 993K has increased
strength and reliability by utilizing a
similar planetary gear group used in
the Cat 994F.
• Front and Rear Frames. The front and
rear frames are spread further apart
for improved bearing life. A key
differentiator from competitive machines
is the box section rear frame and four
plate loader tower. The box section
absorbs torsional forces generated in a
loading cycle, maintaining alignment
for hitch pins and drive line. The four-
plate loader tower resists shock and
torsional loads maintaining hitch and
loader linkage pin alignment.
• Axle Shaft Service Brake. Sharing
similar components with the Cat D9R,
this service brake provides improved
retarding capabilities and better braking
ability. Positive oil flow and brake oil
cooling result in improved brake disc
durability. Additionally, the 993K
third gear run out stopping distance
is greatly reduced.
