DETAIL
Information provided by our supplier of viscous fan units has identified that a number of units have been machined incorrectly which may result in a fan
assembly that is out of balance. A unit that is suspect can be identified by the fan exhibiting vibration under varying engine RPM. The assembly can be
observed running out/oscillating as the engine RPM is increased.
ACTION REQUIRED
At the first opportunity, visually inspect that the fan has not already been updated by checking for the yellow identification mark on the inner ring of the
fan as detailed in the illustration. Replace the viscous unit/water pump as required by referring to the process below.
