1. At the rear of the intermediate boom, assemble the
retract chain sheave (1) to the mounting ears on the
right side of the boom. Place the sheave between the
ears and insert the sheave pin (2) from the left side.

capscrew (3), saved, and the lockwasher (4), saved.
Tighten the capscrew securely.
2. Apply grease to the grease fitting (5) in the pin. Spin
the sheave by hand to ensure the sheave spins freely on
the pin and to distribute grease evenly.

horizontal direction.

each of the capscrews and insert the capscrews
through the mounting holes in the left side of the
