L90 LOWER VALVE BANK ADJUSTMENTS
(valve bank 558-01627 used from machine s/n 22942 (11-1-00) & after)
On 11-1-00, with machine s/n 22942, the L90 Lower Valve Bank changed from 558-01616 to 558-01627 (NOTE: On 295 AC
machines, 558-01616 was never used - it was only used on Truck Mounts) . Changes included:
- Inlet Cover: still has no main relief, but now has a load sense relief.
- Load Sense Relief Valve: a separate one (563-00912) is no longer used on the load sense line, since there is one on
the valve bank now.
All valve sections remain the same.
Sections with Feed Reducers:
Sections 1 and 3 are equipped with adjustable feed reducers to control pressure. When making adjustments on the
feed reducers, install a gauge on the load sense test port located on the tee on pump #1. These feed reducers are
pre-set to 1800 PSI. To decrease the pressure, remove the plastic caps on the feed reducers, loosen the lock nut with
a 10 mm wrench and turn the adjustment screw out (counterclockwise) with a 3 mm Allen wrench.
Sections without Feed Reducers:
To adjust the pressure, install a gauge on the load sense test port located on the tee on pump #1. Adjust pressure at
the load sense adjustment screw on the load sense relief on the valve bank inlet cover. Pressure should be 2800 PSI.
