Caterpillar C30 Marine Engine Application
The 235-2026 hydraulic unit injector pump is used on applicable Caterpillar C30 marine engine configurations.
The C30 can have different engine arrangements depending on the installation and serial-number range. For accurate parts identification, provide the engine serial number and the number from the existing pump.
Alfa Marine Spare Parts can also source C30 fuel injectors, turbochargers, cooling-system parts, pumps, sensors, gaskets and overhaul parts.
Caterpillar C32 Marine Engine Application
The Caterpillar C32 marine engine is another marine application for the 235-2026 and 10R-1001 hydraulic injector pump.

C32 fuel-system arrangements can vary according to engine configuration. The engine serial number should therefore be provided when requesting the pump.
Caterpillar 3412E Marine Engine Application
The 235-2026 / 2352026 hydraulic unit injector pump is also used on applicable Caterpillar 3412E marine engines.
For a 3412E inquiry, provide:
This information helps confirm the correct pump before supply.
How the Hydraulic Unit Injector Pump Works
The hydraulic unit injector pump is an important part of the Caterpillar unit-injector system.
Its role is to generate the hydraulic pressure required for injector operation. This pressure allows the injectors to deliver fuel according to engine operating requirements.
Problems within the hydraulic injector system can affect starting, engine response and fuel-injection performance.
When investigating a pump-related issue, the complete system should be considered, including the injectors, pressure-control parts, seals, oil condition, sensors and related engine parts.
Caterpillar 30R-0083 Reman Hydraulic Injector Pump
The 30R-0083 / 30R0083 is another Cat Reman Injector Hydraulic Pump reference associated with the wider Caterpillar hydraulic injector pump system.
However, 30R-0083 should not automatically be substituted for 10R-1001 or 235-2026 across every engine application.
For marine applications, 30R-0083 is associated with applicable Caterpillar C32 configurations. The engine serial number and pump arrangement should be checked before supply.
235-2026 / 2352026 — Primary pump
10R-1001 / 10R1001 — Primary reman reference
30R-0083 / 30R0083 — Related reman reference requiring application verification
If the existing engine carries 30R-0083, provide the engine serial number and existing pump information when requesting a replacement.
