3.3.4 First Boom Section Installation

1. Use a suitable overhead lifting device and sling and

carefully lift the first boom section into place on the

transfer carriage.

2. Install the boom pivot pin (5) with the previously

used hardware. DO NOT coat the boom pivot pins

with anti-seize compound.

3. Add or remove shims (6) as required until a

maximum total gap of 0.09 in (2,3 mm) is obtained.

Balance the number and thickness of shims equally

on both sides. If an additional (odd) shim must be

added to obtain the proper gap, add to the right side

of the boom.

4. Raise each slave cylinder into position, coat each

mount pin (4) and bore hole with anti-seize

compound and install the mounting pins. Loctite

242™ and torque each capscrew to 18-31 lb-ft

(13-23 Nm). DO NOT stretch or damage the slave

cylinder hydraulic hoses.

5. Use a suitable overhead lifting device and sling

attached to the lift/lower cylinder. Remove slack from

the sling and raise the cylinder into its mount boss

on the underside of the boom.

6. Coat the lift/lower cylinder pivot pin and bore hole

with anti-seize compound. Install the pin and secure

with capscrew. Loctite

242™ and torque to

70-77 lb-ft (95-105 Nm).

7. Remove the slings from the lift/lower cylinder, and

remove the blocks or supports from beneath the

cylinder.

8. As required, install the hydraulic clamps on the

boom and secure the attachment tilt and auxiliary

hydraulic tubes and hoses within the clamps on the

boom and frame. Torque clamp capscrews to

4-8 lb-ft (6-11 Nm).

9. Install new o-rings into the fittings. Lubricate o-rings

with clean hydraulic oil.

10. Uncap and connect the previously labeled hydraulic

fittings to their appropriate locations.
