Page 6: Service Information
The fluid recommended for use in these pumps has a petroleum base and contains agents which provide oxidation inhibition and anti-rust, anti-foam and de-aerating prop- erties as described in DENISON HYDRAULICS standard HF-1. Where anti-wear addi- tive fluids are specified, see DENISON HYDRAULICS standard HF-0. -
Page 7: Troubleshooting
TROUBLESHOOTING STARTUP PROCEDURE pressure readings can be made at appropriate places. • If solenoids in system, check for actuation. (continued) • Start pump drive. Make sure pump fills properly. • Bleed system of air. Recheck fluid level. • Cycle unloaded machine at low pressure and observe actuation (at low speed, if possible). - Page 8 TROUBLESHOOTING TROUBLESHOOTING effect of trouble possible cause fault which needs remedy pressure shocks cogging load mechanical considerations (continued) worn relief valve needed repairs worn compensa- needed repairs slow response in replace or relocate check valves excessive de- improve decompression control compression energy rates excessive line...

Page 21: Assembly Procedure
ASSEMBLY PROCEDURE CLEANING AND INSPECTION The assembly operation must be performed more carefully than the disassembly oper- ation and should be performed in a clean environment using parts that have been ade- quately cleaned. Check the disassembled parts with the exploded view given in Fig. 6 for any missing parts or irregularities. -
Page 22: Barrel, Piston/Shoe/Retainer
ASSEMBLY PROCEDURE Place cylinder barrel 3 on a clean sheet of paper or cloth and insert the three dowels 56 into the holes located outside of the spline hole. Place the holddown ball 14 on top. Compress manually and ascertain spring 18 force. BARREL, Hold the shoe retainer 15 horizontally with one hand, insert the 9 piston assemblies 5 into the bores of the shoe retainer, in order of disassembly. -

Page 25: T' Power Limiter
ASSEMBLY PROCEDURE T’ POWER LIMITER ‘T’ power limiter valve 28 is assembled as follows: See figure 11. Carefully clean the valve body 28-1 and spool 28-2 and soak in clean hydraulic fluid. Install orifice 28-30 in body as shown. To install seat 28-15, insert open end into bore and press in place, beyond the thread- ed hole for fitting, 28-27. -
Page 26: Final Assembly
ASSEMBLY PROCEDURE FINAL ASSEMBLY Assemble compensator or power limiter valve 28 on the mounting pad of port block. The tightening torque is as follows: 8.3 to 9.7 Ibs.-ft., 11 .3 to 13.2 Nm. If the pump contains the ‘J’ or ‘K’ torque limiter, place the control on its mounting pad with the feedback arm on the barrel side of the hanger, with the adjustment facing the same way. -

TEST PROCEDURE 1770 ±. 30 RPM TEST CONDITIONS Operating speed: ± 10 ± 5.5 Oil temperature F., 49 Case pressure 3 to 10 PSI, .21 to .69 bar With the operating speed at 1770 ±30 RPM, record delivery flow rate, drain flow rate PUMP TEST and fluid temperature at minimum outlet pressure and maximum rated continuous pressure. -
Page 28: J' & 'K' Torque Limiter Test
TEST PROCEDURE ‘J’ AND ‘K’ TORQUE LIMITER 1. Note: on all pump adjustment screws, CW rotation increases the setting, and CCW decreases the setting. 2. On the “F” (or “L”) control, back out the maximum pressure adjustment until there is no resistance, and set the differential spool to 250 psi, 17,2 bar. -
Page 29: T' Power Limiter Test
TEST PROCEDURE ‘T’ POWER LIMITER TEST Power limiter setting consists of first adjusting the flow (1) at the high pressure com- pensator setting for the required horsepower, then adjusting the high flow pressure adjustment (3) to the required horsepower at full volume. Before plumbing the pres- sure line to the pump, check for the presence of the orifice 28-28 in the pressure port. -
