the body “O” ring groove.
9. Line up the two cartridge pins (18) with the holes in
cover (4). Assemble cover (4) over cartridge kit and up
against body face. Position cover (4) according to markings
made during step C-2 of the disassembly procedure. Secure

Section VII – Start-Up and Test
A. Start-Up 22.
Install the unit into the system. Make sure the drive shaft is
aligned properly. Be sure all connections are tight and the
hydraulic fluid source is open to pump inlet before start-up.
The pump should prime almost immediately with a minimum
drive speed of 600 RPM. Intermittently operate (jog) the
pump until it primes. It may be necessary to loosen the outlet
fitting temporarily to purge trapped air. Failure of the pump to
prime in a short period of time indicates incorrect assembly
or restricted flow from the reservoir.
B. Test
Use your hydraulic system to test the unit. Refer to the
installation drawings listed in Table 1 for recommended
speeds and pressures. If more precise testing is desired,
consult your Vickers sales engineering office.
