FAQ
Q: What are the signs the 708-7S-00550 fan motor is failing on PC200-8?
A: Engine coolant temperature gauge reads higher than normal at full load, fan audibly slower than normal at rated engine speed, fan motor case temperature above ambient by more than 20 degrees C at operating temperature.
Q: What should I check in the fan circuit before replacing 708-7S-00550?
A: Verify the fan circuit relief valve setting is within specification and the fan pump output flow is correct before condemning the motor. A mis-set relief or low pump flow can mimic motor wear symptoms without the motor being faulty.
Q: Does the fan circuit require flushing when fitting a new 708-7S-00550?
A: Replace the fan circuit inline filter and drain the fan circuit return line before connecting the new motor to remove debris from the old failed motor.
Q: How to confirm 708-7S-00550 fits my PC200-8?
A: Match existing fan motor part number 708-7S-00550 and confirm machine model is PC200-8, PC210-8 or PC220-8. Provide machine serial number for cross-reference.
Q: What quality options are available?
A: We provide original, OEM and high-quality aftermarket versions with stable supply capability.
