Service Magazine SEPD0537, 14 August 2000, "An Improved Bearing For The Swing Boom Is Now Used". Disregard this article. See the article that follows.Description of Change: A new 194-7776 Bearing is now used in the swing boom. The new bearing increases the rigidity of the mounting. This increases the service life of the bearing and of the mounting bolts. The 2N-1287 Flared Elbow must be removed from the 135-2639 Grease Lines Group. A 4S-6399 Flared Connector and a 7K-9197 Swivel Elbow should be installed in order to grease the new bearing.Adaptable To: The new 194-7776 Bearing is a direct replacement to the 134-2313 Bearing. The new bearing assembly is effective with 527 (S/N: 4NS277-UP) and 517 (S/N: 5WW237-UP) Track Skidders. The change is adaptable to all earlier 527, 517, D4H TSK, and D5H TSK Track-Type Skidders. The change is also adaptable to 525 (S/N: 1DN1-UP) Wheel Skidders.
