"H.E.B / CPS" TX; Life Zone LS-WAC5-M Window A/C Fan-motor Bearings Set. Two (2) '0C-A' Bearings in each set! Pre-lubed, they do not need any lubrication. DO NOT LUBE! These window A/Cs are super efficient. However if cleaned with a water hose / pressure washer the fan motor bearings fail. If yours sounds like a hammer drill, it is time to fix it. These steel banded chrome bearings are the solution! Best done by a technician you can find DIY instructions on YouTube. Pack contains 2 (TWO) Bearings, and install instruction page/s. Please leave feedback as it helps keep costs down and provides you with better service. Thank you.
