Rear pump (13) Setscrew (14) Locknut |
Note: Use the same procedure for both pumps. Use locknut (14) and setscrew (13) for the rear pump adjustment. Use locknut (16) and setscrew (15) for the front pump adjustment.
- In order to adjust the rear pump, loosen locknut (14).
- Turn setscrew (13) until the negative flow rate is adjusted to the correct specification.
Note: A clockwise adjustment of setscrew (13) and setscrew (15) increases the flow rate. A counterclockwise adjustment decreases the flow rate. A quarter turn of setscrew (13) and setscrew (15) will change the flow rate approximately
6.7 L/min (1.8 US gpm) at a system pressure of2350 kPa (340 psi) . - Tighten locknut (14) to the specified torque.
