Pictures, Pictures, Pictures!
Email us pictures so we’re both sure your doodad and our doohickey are the same thing.
Complete Power Unit
If it hasn’t been painted over or removed, there should be a sticker on the reservoir with a part # like M-319-0112 or M-3551-0137, and a serial number. Engraved in every aluminum pump base, the 1.5” thick aluminum section between the motor and reservoir, is also where you can find the serial number. A previous owner or the original distributor may have modified your power unit so it’s always a good idea to email us a few pictures so we can make sure the numbers match up with what you have.
Motor
Check the sticker or badge on the motor for a part number. If none present, take pictures.
Pump
Engraved on the back of the pump is a three-digit part number. Removing the reservoir will expose the pump. If you don’t see these numbers, measure the center gear section for the gear thickness. DO NOT take the pump apart.
Coil
Part number should be engraved on the top ring or cast in the plastic housing.
Cartridge Valve
May have engraved part number. Removing valve from the base may be required to view. If no part number is found, refer to complete power unit tips.
Motor Start Solenoid
Should have a sticker or be engraved with a part number.
Reservoir
Not available. Best to take measurements. The complete power unit part number is helpful if available.
Control Box
Not available. How many wires? Single acting or double acting circuit system?
