• Model year 2006 and earlier pumps
General Information
These instructions explain how to install the Discharge
Elbow Kit. This kit replaces both original OEM single-part
elbows, and current 3-part elbows. The 3-part assembly
provides enhanced resistance to caustic chemicals.
These instructions apply to:
Option Package Part Number
HYPRO PUMP DISCHARGE
ELBOW KIT
These instructions presume that the elbow to be
replaced is the older single-part style.
The existing flange or elbow may be attached to the
pump with removable nuts on threaded studs, or removable bolts and nuts. These instructions presume nuts on
studs.
Note: Be careful not to drop or misplace the fasteners.
They are likely in metric sizing, and due to supplier
component changes over time, this manual is
unable to precisely specify their call sizes.

Installation
Flush The Pump
1. Move the implement to a location suitable for flushing the fertilizer system, such as the field most
recently fertilized.
2. Refer to the implement Operator’s manual, and flush
the fertilizer system with water (or if freezing
weather is possible before next use, with RV antifreeze).
3. If necessary, move the implement again, to a dry
well-lighted location suitable for disassembly.
4. Raise and unfold the implement. Lower it, or if you
prefer to leave it raised, install lift cylinder locks.
5. Secure the tractor.

CAUTION
Because the discharge line usually exits upward from the
pump, it is almost certain to contain a significant amount of
fluid. Wear appropriate protective gear and ensure that the
resulting spillage is contained, such as with a bucket under
the pump.
