8. For propel motor being checked, actuate propel
forward function at full speed for one minute. Record
amount of leakage. Repeat procedure for reverse.
If leakage is more than specification, repair or replace
motor.
Propel Motor--Specification
Leakage ................................................... 1.5--2.0 L/min (0.4--0.53 gpm)
new acceptable while propelling
with track raised
Leakage ........................................................... 3.4 L/min (0.80 gpm) used

B--Cap
propelling with track raised
C--Fitting
D--Calibrated Container
If leakage is substantially more in one direction than the
other, a seal in the rotary manifold may be leaking. To
isolate leakage to the propel motor or rotary manifold,
check leakage at the propel motor.
