description

The 110-8898 is separate from the valve camshaft. It is installed inside the mechanical injection pump, driving plungers to regulate fuel delivery timing. This 3406 engine uses mechanical fuel pump and works under heavy mining loads. Lobe scoring, spalling or journal wear causes shifted injection timing, uneven fuel supply, fluctuating power and black smoke. Severe damage locks the plunger and disables the fuel pump. Its timing profile is made for fuel injection and cannot be swapped with valve camshafts.

The Fuel Pump Camshaft is used through its cam profiles and mechanical motion, it controls the timing and delivery of fuel to each cylinder, ensuring optimal engine performance, fuel efficiency, and emission control.

FAQ 

1. Does 110-8898 fit 3408 fuel injection pump?
No. 3406 and 3408 have different plunger stroke, cam lift and timing, non-interchangeable.

2. Can the camshaft stay in service with minor pitting?
Fuel pump cam runs under heavy impact. Pitting spreads quickly and replacement is recommended.

3. Can I reuse old plungers with new camshaft?
Check plunger clearance. Replace plungers together if scoring or excessive wear is found.

4. Can this fuel pump camshaft replace the engine valve camshaft?
No. They have different functions, lift and timing. Mixing them causes severe engine failure.
