설명
On the E-series Volvo large excavators the fan motor is a compact hydraulic unit bolted behind a cooling pack that has to shed the heat of a 284 kW to 450 kW engine, depending on model. Volvo’s own parts catalogue does not return a citable page for 14641300, so the item name here is trade-established rather than manufacturer-confirmed, and we say so rather than inventing a specification.
적용 기종
Volvo EC480E and EC950E excavators, with the EC950E rated by Volvo CE at 450 kW from its D16 engine in published specification. Dealer parts data groups 14641300 with 14673696 and 14674307 in the same fan motor family, which is consistent with a shared mounting and hub arrangement across the E-series large machines. Confirm against the number cast on your own motor.
What the pairing means
Every fan motor in this family is driven by a fan pump, and on the E-series machines that pump is a separate item with its own failure pattern. The practical point for a workshop: if the old motor failed by shedding material, the pump has already swallowed some of it, and the two should be judged together rather than one at a time. Measure flow at the motor ports before deciding which component to replace. Our 유압 팬 모터 진단 가이드 및 팬 펌프 진단 가이드 set out both tests.
Fitting practice on an E-series machine
- Photograph the hose routing before stripping. Port identity matters where the fan reverses for core cleaning.
- Sample the oil and inspect the return filter element; glitter changes the scope of the job.
- Flush, then prime the new motor’s casing with clean oil before the first crank.
- Keep the case drain unrestricted to tank, since casing back-pressure is what finishes shaft seals.
- Target ISO 4406 18/16/13 or better, then prove full fan speed and reverse function under load and record both temperatures.
