Perform the following steps to complete the collet installation process.
Apply 4C-5599 Anti-Seize Compound (C) to the outside surface of the 389-4917 Collet (2).
Install the 389-4917 Collet (2) into the pin bore inside the lift arm.Note: The collets on each end of the pin should extend the same distance from the lift arm.
Apply 4C-5599 Anti-Seize Compound (C) to the plugs.
Install three Plugs (7) into the Collet (1). Torque the plugs to 12 3 N m (9 2 ft lb).
Apply 4C-5599 Anti-Seize Compound (C) to the bolt threads.
Install 3E-8010 Bolt (6) with 9X-8399 Washer (3). The bolt threads should engage the threads inside the 389-4937 Collet (1).Note: Start the bolt from the inside collet on the lift arm.

Perform the following steps to complete the pin installation process.
Tighten 3E-8010 Bolt (6) to a torque of 1800 200 N m (1330 150 lb ft).
Strike the collets and the lift cylinder rod end with a hammer until the bolt torque drops to 950 N m (700 lb ft).
Tighten 3E-8009 Bolt (6) to a torque of 1800 200 N m (1330 150 lb ft).
Strike the collets and the lift cylinder rod end with a hammer until the bolt torque drops to 1600 N m (1180 lb ft).
Tighten 3E-8009 Bolt (6) to a torque of 1800 200 N m (1330 150 lb ft).Note: After the bolt is tightened, each collet should extend the same distance from the lift arm.Torque the bolts after the machine has operated for 8 hours and after the machine has operated for 50 hours.
