Description of Change: A new bearing in the fan pump has an increased load rating. The new bearing prevents oil leaks from the seal of the fan pump.
Adaptable To: The new 222-8288 Ball Bearing replaces the former 3D-0053 Ball Bearing in the fan pump. The new bearing is effective with the new 222-8282 Gear As in the fan pump. The new 222-8282 Gear As consists of the new bearing and a 196-8245 Gear. The effectivity of the new bearing is listed in Table 1. The new bearing is adaptable to the models that are listed.
The location of the new bearing is shown in Illustration 2. Replace the former bearing with a new bearing if oil leaks from the seal of the fan pump.
