TM 5-3895-369-14
The following procedure requires the ability to produce a sufficient load to create maximum system
pressure. Take necessary precautions or injury or death to personnel could result.
STE/ICE-R PRESSURE TEST
#51
(1) Prevent tractor from moving forward
under load.
(2) Remove output pressure line
(para 5-55) from hydrostatic motor.
(3) Power up STE/ICE-R to vehicle battery
source (TM 9-4910-571-12&P, in
TK mode).
(4) Setup STE/ICE-R pressure test #51
at output port.
(5) Start engine (pare 2-9).
(6) Engage hydrostatic motor (pare 2-10).
(7) Bring tractor up to operating speed
(1800-2000 rpm)
(8) Perform STE/ICE-R pressure test #51
(9) Hydrostatic motor output pressure
should be 3000 to 6000 psi (20760 to
41412 kPa).
(a) lf output pressure is not within
limits, replace motor (para 5-55).
(b) If pump output pressure is within
limits, indicates faulty two-speed
range box.
TWO-SPEED RANGE BOX
INSPECTION
(1) Remove rear axle (para 5-64).
(2) Remove two-speed range box from
differential.
(3) Inspect two-speed range box for
damage (para 5-50).
(4 If two-speed range box is
damaged, replace/repair
(b) If two-speed range box is not
damaged, replace/repair
differential (paras 5-68 and 5-69).
