Caterpillar 340-7732 Applications
Caterpillar lists the discontinued 340-7732 / 3407732 PUMP GP-AUX for:
Marine Engines
- Caterpillar C18
- Caterpillar 3406E
- Caterpillar C15
Other Applications
- Caterpillar C18 generator set
- Caterpillar C-15 petroleum engine
- Caterpillar C18 petroleum package
The exact pump should always be verified against the engine serial number and arrangement number, because not every C15, C18 or 3406E configuration uses the same auxiliary pump.
