Preventive Maintenance
4-10 Stainless Max Series Pumps
5. Drain the oil from the pedestal into a suitable container (1.5 pints/
0.7 liters).
6. Remove the oil fill/dipstick and replace the drain plug. (See
Figure 4-7: “Pedestal Oil Change” on page 4-9.)
7. Fill the pedestal with an approved oil per preceding Step 2 and
run the pump for a short period, then re-check the oil level.
Check Drain Lines to Multi-Drain
Drains are supplied on the pump and piping at the lowest points
where water could collect and freeze, rendering the pump ineffec-
tive. Most of these drains are piped together to a multi-drain to
allow the entire system to be drained by one valve.
It is necessary to inspect each line of the multi-drain to ensure the
entire system is draining when the valve is operated.
Inspect each connection and verify the individual lines to the multi-
drain are free of debris. Repair or replace any lines that are dam-
aged, kinked, or corroded.
Tank to Pump Flow Rate Test
Note: This procedure is provided as a reference only. It does not
supercede any local procedures.
1. Fill the water tank until it overflows.
2. Close the tank fill line, bypass the cooling line, and all the pump
intakes.
3. Attach sufficient hose lines and nozzles to pump the desired
discharge rate.
4. With the pump in gear, open the discharge to which the hose is
attached and begin pumping water.
5. Increase the engine throttle until the maximum consistent pres-
sure is obtained on the discharge gauge.
6. Close the discharge valve without changing the throttle setting.
Refill the tank through the top fill opening or a direct tank line.
The bypass valve may be opened during this time to prevent
pump overheating.
