Primary Boom Cable Track
The primary boom cable track guides the cables
and hoses running up the boom. It can be repaired
link by link without removing the cables and hoses
that run through it. Removing the entire primary
boom cable track is only necessary when
performing major repairs that involve removing the
primary boom.
How to Remove the Primary
Boom Cable Track
Note: When removing a hose assembly or fitting,
the O-ring (if equipped) on the fitting and/or hose
end must be replaced. All connections must be
torqued to specification during installation. Refer to
Specifications,
Hydraulic Hose and Fitting Torque
Specifications.
Note: Perform this procedure with the machine on a
firm, level surface.
Note: Perform this procedure with the boom in the
stowed position.
