Q&A Section
Q1: Will this fan fit the older CX210 (Tier 2) model?
A: No. The 447004A1 is specifically designed for the B-Series (Tier 3) machines. Tier 2 machines often use a different fan pitch and mounting diameter. Always check your serial number before ordering.
Q2: How do I know if my 447004A1 fan needs to be replaced?
A: Aside from visible cracks or chips on the blades, look for signs of "scuffing" on the blade tips. This indicates the fan is striking the shroud due to worn engine mounts or a failing fan clutch, which can lead to catastrophic fan failure.
Q3: Does the 447004A1 fan include the mounting hardware?
A: Generally, this part number refers to the fan blade assembly only. You should reuse your existing mounting bolts or replace them with high-grade (Grade 10.9) bolts if they show signs of stretching or corrosion.
