TEST HYDRAULIC PUMP
1. Remove plug (Figure 1, Item 3) from test block (Figure 1, Item 2) mounted on rear of hydraulic pump
(Figure 1, Item 1).
2. Install 5 ft pressure hose and 3000 psi (20685 kPa) gauge (Figure 1, Item 4) on test block
(Figure 1, Item 2).
3. Start engine and engage PTO (TM 9-2320-273-10). Bring engine to 2000 rpm and read gauge.
4. Gauge must read 2000 psi (13790 kPa) or greater. If pressure is less than 2000 psi (13790 kPa), perform
control valve pressure adjustment. If pressure cannot be reached by adjusting control valve, replace or
rebuild hydraulic pump.
