Fuel Injector Pump & Common Rail & Injector Kit 7249380 7030409 7275454 for Bobcat E32 E35 E42 E45 S540 S510 S530 S550 T450 T550 T590

Fuel Injector Pump & Common Rail & Injector Kit 7249380 7030409 7275454 for Bobcat E32 E35 E42 E45 S540 S510 S530 S550 T450 T550 T590

This fuel injector is a direct replacement unit designed for Bobcat E32 E35 E42 E45 S540 S510 S530 S550 T450 T550 T590. It delivers a precise atomized fuel spray into the combustion chamber for efficient burning. When an injector fails, the affected cylinder runs lean — or doesn’t fire at all — which puts extra stress on the remaining injectors and can damage the catalytic converter over time.

Signs You Need a Replacement

If your equipment is showing any of these symptoms, the injectors & nozzle may be the cause:

• Black or gray exhaust smoke — especially noticeable under load or acceleration
• Rough or uneven idle — the engine shakes or vibrates at low RPM
• Engine misfire or hesitation — stumbling when you step on the throttle
• Poor fuel economy — filling up more often for the same work
• Knocking or nailing sound — metallic noise from the engine under load
• Fuel smell in engine oil — diesel leaking past the injector seat into the crankcase

Replace as a Set

Replacing injectors as a set is the standard practice. Mixing old and new injectors creates uneven spray patterns — the new unit works harder and burns out faster. On multi-cylinder engines, a single failing injector can reduce total output by 20 to 30 percent. When you pull the old injectors, inspect the seats and copper sealing washers. If the seats are pitted or the washers are crushed, replace them before installing the new units.

Frequently Asked Questions

Will this fit my Bobcat E32?
Yes. This part is designed to fit the Bobcat E32, E35, E42, E45 among other models listed in the compatibility table above. Verify your specific model and engine code before ordering to ensure the correct fit.

Can I cross-reference HRP741 with 7249380?
Yes. Both HRP741 and 7249380 are interchangeable OEM numbers for this part. They refer to the same component with the same specifications, just different part number revisions. This replacement fits all applications listed for either number.

How do I check if my engine code (HRP741) matches?
The engine code is stamped on a metal tag attached to the engine block, usually near the timing belt cover or on the cylinder head. Compare the code you find with the list above. Engine codes are 3 to 6 characters long and use a combination of letters and numbers.

What are the common failure signs on a Bobcat engine?
On Bobcat engines, watch for black exhaust smoke under load, rough idle, misfire codes (P0300 series), and loss of power. A single failing injector can reduce engine output by up to 25%. If you notice fuel in the engine oil, the injector seat seal is likely compromised — replace it immediately to prevent crankcase contamination.
