Description of Change:
Reference: Service Magazine, October 26, 1998; Page 9; "Improved Steering Spherical Race Bearing Available".
Disregard the referenced article and refer to the text that follows.
An improved 163-9236 Spherical Race Bearing is available as a direct replacement for the former 6M-8953 Spherical Race Bearing. Also, an improved 138-8605 Spherical Race Bearing is available as a direct replacement for the former 9D-2887 Spherical Race Bearing. The 163-9236 Spherical Race Bearing and the 138-8605 Spherical Race Bearing feature an internal radius which will decrease interference between the spherical race bearing edge and ballstud when the steering arms are at the extreme ends of travel.
Adaptable To: The 163-9236 Spherical Race Bearing is effective with 776D (5ER108-Up) Tractors; 775D (6KR366-Up, 8AS1-Up) Quarry Trucks; 773D (7ER925-Up, 7CS1-Up), 777D (3PR942-Up), 777D (2YW9-Up) Off-Highway Trucks and 73D (1GW123-Up, 9YS1-Up) Underground Trucks. The 163-9236 Spherical Race Bearing is a direct replacement for the former 6M-8953 Spherical Race Bearing used in earlier machines.
The 138-8605 Spherical Race Bearing is effective with 771D (6JR104-Up, 6YS1-Up) Quarry Trucks; 769D (5TR332-Up, 5SS1-Up) Off-Highway Trucks; and 69D (5TR356-Up, 9SS1-Up, 9XS1-Up) Underground Trucks. The 138-8605 Spherical Race Bearing is a direct replacement for the former 9D-2887 Spherical Race Bearing used in earlier machines.
NOTE: Some earlier 69D Underground Trucks have the same Product Identification Number (PIN) prefix as some 769D Off-Highway Trucks.
