HELPFUL TIPS
• With TrunkPump ® raised, Fill with water before use.
• Never run pump dry.
• Transport TrunkPump ® in raised position to keep as much water in unit as possible.
• Always use a strainer to keep out debris and extend pump life.
• Use the shortest suction hose possible to get the pump to prime as fast as possible.
• For quick priming, use full throttle - then reduce rpms to 80% when flow is established.
• In shallow water, idle down to allow sufficient volume of water to feed suction line.
• Keep all guards in place during operation and avoid contact with moving parts.
• Disconnect TrunkPump ® from tractor and PTO when servicing.
• Be sure all hose gaskets are in place and Teflon tape has been used on pump fittings.
• Read and follow instructions in PACER ® /AMT ® pump manual and TRUNKPUMP ® manual.

GENERAL MAINTENANCE
BELT: 5L-250 / BX22 or 5L-270 / BX24 (BX cogged belts are recommended)
• Check belt at regular intervals. Replace if damaged or severely worn.
• Be sure your belts are properly tensioned.
The adjustment is made by loosening the bolts on the pump base, prying the pump (or tightening adjust-
ment bolt) in the adjustment slots, then tightening the bolts down again. Use of a nut locking solution
might be helpful if you have an especially rough running machine. Over tensioning will cause undue
wear on the bearings, while an overly loose belt will slip. Find the middle ground. The belt should give
about 1/2” under medium pressure. An adjustment may be needed after initial pump use as the belt will
expand slightly under operational temperature and will seat itself in the pulley.
INTERNAL PUMP PARTS:
• If diminished performance is noticed, replace gaskets, o-rings and/or impeller and volute ac-
cording to repair kit instructions.
PTO SHAFT
• Grease PTO shaft at recommended intervals (see PTO shaft for maintenance schedule)
GEARBOX
• The initial oil should be changed after 50 hours of use then approximately every 1000 hours
or once a year.
• Oil type:
• Tilt unit on side to drain via drain plug located near
output shaft.
• Return to upright position, leave drain plug out and fill
unit via breather port until oil comes out drain plug -
Approximately 15 fluid ounces / .4 liters
• Secure drain plug and breather following oil change.
• Dispose of used oil responsibly.
