Hydraulic oil can be moderately flammable and can be an irritant to skin, eyes, and respiratory
system. Avoid prolonged exposure. Eye protection and rubber gloves must be worn when working
with hydraulic oil.
Install hydraulic system tester at ports (5 and 6) for flow tests per TM 94940-468-14. Check
hydraulic propulsion motor case drainage rate. Check rate at port (5) for left hydraulic propulsion
motor and at port (6) for right hydraulic propulsion motor. Acceptable drainage rate is less than 3
gpm (11 l/min) with engine at 2640 +40 rpm and control handles full forward.
Replace/repair hydraulic propulsion motor per paragraph 2.32. Most likely cause of problem is
malfunctioning flushing valve.
