SECTION 4: HYDRAULIC KIT INSTALLATION
4.6 HOSE ROUTING – BOOM
•
Fit the nylon abrasive sleeve over the loose ends of the Dipper hoses.
Using the GREEN color coded hoses for the Boom, connect these to the
dipper arm hoses. (Fig 4.6.1)
•
Lay the Boom hoses along the top of the boom arm in preparation of
determining the best hose clamp position for this part of the installation.
(Fig 4.6.2)
•
Mark the position of the top hose clamp on the boom, allowing for the hose to follow the boom
movement relative to the dipper arm movement on the top pivot point. Following the existing
hose route and length through this pivot area is recommended.
•
Mark the position of additional hose clamps along the top of the boom. With some kits hose
clamps are only provided for the Dipper. Use the Zip-Ties provided for securing the coupler
hoses to the boom. Prepare the surface of the boom for welding in these locations. Weld clamp
assemblies ensuring that only the vertical ends of the clamp brackets are welded. Touch up
paint the boom and clamp to match the carrier machine color.
• Tighten all hose joints between the coupler cylinder and the dipper arm to boom connections.
• Tighten the clamp assemblies, pulling through any excess hose, working from the dipper end
to the bottom of the boom. Allow “hose slack” for pivot movement and ensuring that the hose
