RECOMMENDED PREVENTIVE MAINTENANCE PROCEDURE
1. Lubrication.
Oil level in the transmission should be maintained even with the oil level plug, which is located near
the input shaft on the front side of the gear case. It is recommended that the oil be changed every
three months and after any prolonged period of pumping. Check oil level at regular intervals.
Should your department be fortunate enough to have only a few calls during the year, it will be
beneficial to operate the pump once a week - perhaps during drill work.
IMPORTANT - MIDSHIP PUMPS WITH SPLINED INPUT AND OUTPUT SHAFTS REQUIRE
THE USE OF SAE 20 WEIGHT NON-DETERGENT MOTOR
OIL. DO
NOT USE HEAVIER
OIL.
MIDSHIP PUMPS WITH FLANGED INPUT AND OUTPUT SHAFTS REQUIRE THE USE OF
SAE EP-90 LUBRICANT. ALL OTHER PUMPS (FRONT MOUNTS, PTOs, ETC.) REQUIRE
THE USE OF SAE 20-WEIGHT NON DETERGENT MOTOR OIL. DO NOT USE HEAVIER
OIL.
WARNING: Insufficient oil will result in serious damage to the bearings and other internal
parts. Too much oil or too heavy oil will result in unnecessary loss of power and
unnecessarily high oil temperature. Drain oil and renew at least every 12 months.
WARNING: It is normal practice to ship pump to builder without oil, oil must be added
before operating.
2. Drafting.
When pumping large volumes of water, the strainer should be submerged at least two feet below
the surface. Use extra caution when drafting from shallow water sources with mud, sand or gravel
bottom. Keep the strainer off bottom by placing it inside a barrel with the top cut down, or use a
similar method.
3. Salt Water Use.
After pumping salt water, pump from a hydrant for a few minutes to flush out the pump. Also, follow
this procedure after pumping excessively dirty water.
4. Cold Weather.
It is recommended that during cold weather the pump should be drained at all times, except when
kept in a heated fire house.
CAUTION: If long runs in very cold weather are expected (such as in rural areas), it is wise
to maintain a dry pump regardless of storage conditions.
5. Final Test Before Housing Engine after a Fire or Drill.
In addition to regular lubrication and maintenance to the pump, the following procedure is
recommended to assure proper operation under emergency conditions:
a) Open discharge valves and remove caps.
b) Close drain valve(s).
c) Tighten suction caps.
The pump utilizes oil-bath type lubrication of all gears and bearings in the pump transmission.
