Fuel Injection Pump for CASE 590SM Backhoe Loader — J991962 / 3930153

The CASE 590SM is one of the most widely deployed backhoe loaders in the construction industry — and when its injection pump fails, the jobsite stops. This brand-new aftermarket injection pump is a direct bolt-on replacement covering a wide range of OEM cross-reference part numbers for the 590SM, precision-calibrated to restore proper fuel pressure, injection timing, and delivery volume. Get your machine back to digging, loading, and earning — without the OEM price tag.

Why Replace Your Injection Pump?

A failing injection pump causes hard starts, loss of digging and lifting power, excessive smoke, and rising fuel consumption. Left unaddressed, low fuel pressure accelerates injector wear and can cause engine damage far more costly than the pump itself. At ~$1,000, this is a high-value repair that protects a much larger machine investment — and keeps your 590SM productive on the job.
