John Deere J BACKHOES 310SJ TMC - Manual (Page 13)

Engine hood is constructed
of a resilient composite
material that resists impacts
and damage. Standard grille
extensions further protect the
front end.
Backhoe boom, dipperstick,
stabilizers, and loader are
box-constructed of low-alloy
steel for maximum strength.
No more stacked hydraulic
and transmission coolers
in front of the radiator. With
improved airflow, fan speed
has been reduced for less
debris build-up and noise.
Cleanout is easier, too.
Wet-sleeve liners provide
uniform engine cooling and
longer durability than cast-in-
block designs. Sealed front axle and larger
kingpins and differentials
help ensure drivetrain
durability. Large pins and replaceable
bushings deliver long-term
durability, and keep the
backhoe and loader tightly
secured and digging true. Unlike axles that rely on
internal augers to direct oil
to critical components,
Deere’s design provides full-
time, full-axle lubrication on
any angle in any terrain. Planetary final drives distrib-
ute loads over three gears
and are sealed in a cooling
oil bath for long life and
trouble-free service.
