Milton CAT 345D L - Manual (Page 8)

Undercarriage Options. Track with
Positive Pin Retention 2 (PPR2) and
cast idlers are available as attachments
on the 345D L. The PPR2 prevents
loosening of the track pin from the track
link and the cast idler is designed for
extended life. Both options are ideal for
extreme applications or those that require
a large amount of travel.
Travel Motors. Two-speed axial piston
hydraulic motors provide the 345D L
drive power and speed selection.
When the high-speed position is
selected, the machine automatically
changes between computer-controlled
high and low speeds depending on
drawbar-pull requirements.
Straight-line Travel Circuit. The straight-
line travel circuit is incorporated into
the hydraulic system, which maintains
low-speed, straight-line travel, even
when operating the front linkage.
Final Drive. The final drives are a three-
stage planetary reduction. This design
results in a complete drive/brake unit
that is compact and delivers excellent
performance and reliability.
Track. The 345D L comes standard with
a grease lubricated track called GLT4.
The track links are assembled and sealed
with grease to decrease internal bushing
wear, reduce travel noise, and lower
operating costs by extending service life.
The track link for the 345D L has been
re-designed to avoid the concentration
of stresses and improve durability
and reliability.
Track Guards. The idler guard and
bolt-on center guard are standard
equipment. They help maintain track
alignment while traveling or working
on slopes. For applications that require
additional track protection or alignment,
optional guards are available.
