Review Content

Mark L. | E320D Excavator

5/5

Installed 0R-8633 on my E320D excavator and couldn't be happier. The engine runs smoother, idles steady, and fuel use is down about 7%. Installation was a breeze-direct bolt-on, no modific-ations needed. It's been 4 months of heavy use and no issues at all. Worth every penny for OEM quality without the OEM price!

Ana R. | Mining LHD Vehicle

5/5

Our mining site is extremely dusty, and ordinary injectors fail within 2-3 months. This 0R-8633 injector has held up for 6 months strong-its anti-corrosion coating works perfectly, and it's just as reliable as the original c-aterpillar part but much more affordable. Highly recommend for anyone with mining equipment!

James T. | 3116 Generator Set

4.8/5

Perfect match for our c-aterpillar 3116 generator set-provides stable power output 24/7. The only small complaint is that it didn't come with a quick-install guide, but the installation was straightforward if you're familiar with injectors. Quality is top-notch, and the 12-month warranty gives us peace of mind for our industrial power needs.

Carlos M. | 966F Loader

5/5

This injector is a game-changer for our 966F loader. It handles frequent acceleration and deceleration perfectly-power kicks in instantly, which has shortened our loading cycles. It fixed the black smoke and power loss issues we had with our old injector. Delivery was fast (2 days with Prime), and customer support was responsive when we had a question. Will buy again!

Operation Type

Detailed Instructions

Replacement Steps

1. Shut down the engine, close the fuel valve, and relieve system pressure; 2. Disconnect the fuel line and electrical connector; 3. Remove the old injector; install the 0R-8633 and torque to OEM specific-ations; 4. Reconnect all components, open the fuel valve, exhaust air, and check for leaks.

Daily Maintenance

1. Inspect for leaks or dirt accumulation every 1,000 working hours; 2. Use filtered low-sulfur fuel to prevent nozzle clogging; 3. Clean the injector every 2,000 working hours; 4. Check high-pressure joint seals regularly to avoid leaks.

Fault Troubleshooting

• Insufficient Power/Black Smoke → Clogged nozzle or pressure deviation → Clean or adjust pressure; • Hard Starting/Shaky Idle → Air in system or seal failure → Exhaust air or replace seal; • Leakage → Check high-pressure joint torque or seal damage.
