Installation
1. Install fittings from old pump onto new pump.
Tighten all fittings to ensure no leaking occurs
during operation.
2. Install new pump to frame.
3. Install bolts and nuts. Torque to 225 +/- 10 in-lb
(25.42 N•m).
NOTICE
Fill pump casing with hydraulic oil before installing top
case drain fitting. Not doing so may cause internal
damage to the pump at start up.
NOTICE
To prevent premature failure of the keyless bushing
and/or pump shaft:
• Do not use impact of any kind to move it along the
shaft. Loosen, move, re-torque.
• Ensure bushing bore and pump shaft are com-
pletely free of paint, grease, oil, and debris of any
kind. Thoroughly clean using non-petroleum based
solvent (isopropyl alcohol).
• Pump shaft must fully engage the gripping area of
the bushing.
• Over tightening the bushing nut could result dam-
age to the bushing or the pump shaft.
