4DK Series Pumps
SECTION 3 PREVENTIVE MAINTENANCE
For climates with ambient temperatures below
freezing (32°F/0°C), use Dextron III synthetic
oil (Cognis 2803 or equal).
An oil level sight gauge is provided on the
side of the gear box. (See Figure 6: "Sight
Level Gauge/Lubrication.") The gear box
requires five (5) quarts (4.7liters) of oil to
bring the level to the halfway point on the
sight level gauge (minimum FULL level).
Adding oil in excess of the halfway point may
cause the unit to run in excess of higher than
recommended operating temperature.
AFTER EACH USE
❑ Check seals for leaks.
❑ Check piping for leaks.
❑ Close all valves and caps.
WEEKLY
❑ Verify operation of pump shift indicator.
❑ Check drive lines.
MONTHLY
Check drive lines and flange bolts to ensure:
❑ No bolts are missing.
❑ All bolts are tight.
❑ Bolts used are “Grade 8” strength.
Check pump mounting bolts to ensure
❑ No bolts missing.
❑ All bolts are tight.
ANNUALLY
