Illustration 1. Location of "A" and "B" Pins.Procedure for "A" Pin:
Illustration 2. Section A-A (refer to Illustration 1). Make sure that collets, pins and all mating surfaces are clean before beginning procedure.1. When installing "A" pins, position the lift arms so that they are evenly spaced between the NEEF (Non-Engine End Frame) and the lift arm bores.2. Insert approximately the same number of 103-1814 Shims 3.0 mm (.12 in) (6) and/or 103-1815 Shims 5.0 mm (.20 in) (7) on both sides of the lift arm (see Illustration 2). This should evenly space the lift arm between the NEEF bores. This procedure is to determine the necessary number of shims. Do not FORCE shims into the space between the lift arm and NEEF bores.3. Remove the determined number of shims.4. Insert 8X-0660 Pin (3) through the NEEF and lift arm, with the determined number of shims in position. Apply 5P-0960 Molybdenum Grease or equivalent to the outside of the 8X-0660 Pin before installation. Measure the distance on both sides of the installed pin and position pin evenly on both sides.5. Install 8X-0663 Collets (2) on both sides of the lift arm. Apply 4C-5599 High Temperature Anti-Seize to the inside of the collet before assembly.6. Install a 3E-8011 Bolt (1) and 3S-7023 Washer (5) through 8X-0660 Pin. Apply 4C-5599 High Temperature Anti-Seize to the bolt threads before assembly.7. Install the 3S-7023 Washer (4) and the 8T-1583 Nut (8).8. Tighten the bolt to a torque of 1800 200 N m (1332 149 lb ft). Maintain the 8X-0663 Collets spacing as evenly as possible on both sides of the lift arm as this procedure is being followed.9. Use hammers to impact the collets on both sides to sufficiently cause the bolt torque to drop to less than 950 N m (700 lb ft).10. Tighten the bolt to a torque of 1800 200 N m (1332 149 lb ft).11. Use hammers to impact the collets on both sides again to sufficiently cause the bolt torque to drop to less than 1600 N m (1182 lb ft).12. Tighten the bolt to a torque of 1800 200 N m (1332 149 lb ft). Tighten the bolt to a torque of 1800 200 N m (1332 149 lb ft) after 50 hours of operation.13. Repeat this procedure for the other "A" Pin.Procedure for "B" Pin:
Illustration 3. Section B-B (refer to Illustration 1). Make sure that the collets, pins and all mating surfaces are clean before beginning the procedure.1. Position the bucket evenly over the lift arm bores.2. Insert approximately the same number of 103-1815 Shims 3.0 mm (.12 in) (15) and/or 103-1816 Shims (.20 in) (16) to both sides of the lift arm, to evenly space between the bucket and the lift arm (see Illustration 3). This procedure is to determine the necessary number of shims. Do not FORCE the shims into the space between the lift arm and the bucket bores.3. Remove the determined number of shims.4.
