TM 5-3895-373-34 Table 2-3. Propulsion System Troubleshooting - Continued. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION 1. TRACK FAILS TO MOVE OR MOVES SLUGGISHLY- Continued. WARNING 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. NOTE The following test requires use of a hydraulic system tester. Install tester in-line at discharge of hydraulic pump per TM 9-4940-468-14. Make sure ratings of all fittings and hoses used are adequate for maximum pressures and flows being tested. There are two discharges located on each hydraulic propulsion pump. One discharge supplies the hydraulic propulsion motor in forward travel. The other discharge supplies the hydraulic propulsion motor in reverse travel. Replace or repair faulty hydraulic propulsion pump if either discharge fails the following check. Step 5. Connect hydraulic system tester pressure port to (3) and reservoir port to (4). With control handle at maximum forward position, check flow. Connect hydraulic system tester pressure port to (4) and reservoir port to (3). With control handle in maximum reverse position, check flow. Check maximum discharge flow rate of hydraulic propulsion pump. Propulsion pump discharge flow rate should be no less than 26 +1-1/2 gpm (98 ±5,7 l/min) at 3000 psi (20 685 kPa) with engine at 2640 ±40 rpm. If discharge is less than 26 +1-1/2 gpm (98 +5,7 l/min) at 3000 psi (20 685 kPa), replace/repair hydraulic propulsion pump per paragraph 2.30. 2-26
