TM 5-3895-373-34 Table 2-3. Propulsion System Troubleshooting - Continued. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION 3. TRACK MOVES ONE DIRECTION ONLY (FORWARD OR REVERSE) - Continued. WARNING Hydraulic oil can be moderately flammable and can be an irritant to the skin, eyes, and respiratory system. Avoid prolonged exposure. Eye protection and rubber gloves must be worn when working with hydraulic oil. Never crawl under paving machine or screed to perform maintenance unless equipment is securely cribbed. Equipment may fall and cause serious injury or death to personnel. Step 2. Install hydraulic system tester at ports (5 and 6) for flow tests per TM 9-4940-468-14. Check hydraulic propulsion motor case drainage rate. Check flow 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 at full forward. Replace/repair hydraulic propulsion motor per paragraph 2.32. Most common problem is malfunctioning flushing valve. Step 3. Disconnect hydraulic system tester per TM 9-4940-468-14. Reconnect all hydraulic lines. Remove cribbing and lower per TM 5-3895-373-20. 2-30
