Fuel Filter 1R-0762 — Caterpillar OEM Replacement
The 1R-0762 is a high-efficiency fuel filter/water separator designed as a direct OEM replacement for Caterpillar diesel engines. It removes solid contaminants and separates emulsified water from diesel fuel, protecting injection pumps, injectors, and the entire fuel system from premature wear and corrosion.
Key Specifications
| East Filters Item No. | EF-43002 |
| OEM Part Number | 1R-0762 |
| Filter Type | Fuel Filter / Water Separator |
| Compatible Brand | Caterpillar (CAT) |
| Filtration Media | High-grade cellulose with hydrophobic barrier |
| Application | Diesel engine fuel systems |
Features & Benefits
- Superior water separation — hydrophobic media repels moisture and prevents free water from reaching the injection system, reducing injector tip failure and fuel system rust.
- High dirt-holding capacity — engineered pleat geometry extends service intervals without sacrificing flow rate.
- OEM-equivalent build quality — manufactured to meet or exceed Caterpillar OE specifications for fit, form, and function.
- Heavy-duty construction — all-steel canister withstands high pressure and vibration typical of earthmoving, mining, and agricultural equipment.
- Corrosion-resistant coating — outer shell finished with anti-rust treatment for longevity in harsh environments.
Compatible Applications
This filter fits a wide range of Caterpillar diesel engines commonly found in:
- Construction equipment: excavators, bulldozers, wheel loaders, motor graders
- Mining machinery: haul trucks, drills, underground loaders
- Agricultural tractors and harvesters
- Marine & industrial power generation: diesel generator sets
- On-highway trucks with CAT engine configurations
Why Replace Your Fuel Filter Regularly?
A clogged or saturated fuel filter causes:
- Reduced engine power and poor throttle response
- Hard starting and rough idle
- Increased fuel consumption
- Premature injector and injection pump failure
For demanding operating conditions (high dust, high humidity), we recommend replacing the fuel filter every 250–500 hours or per your engine manufacturer's maintenance schedule.
