Precautions for installation work
q Tighten all of the bolts and nuts (sleeve nuts) to the specified torque (KES).
q Install the hoses without twist and interference, and securely fasten the clamps located in-between if
they are.
q Replace all of the gaskets, O-rings, cotter pins, and lock plates with new parts.
q Bend the cotter pins and lock plates securely.
When applying adhesive, clean and degrease the part, and apply two to three drops of adhesive to the
q
threaded portion.
q When applying liquid gasket, clean and degrease the surface, and apply it uniformly after making sure
that the surface is free from dirt or damage.
Clean all of the parts, and correct any damage, dents, burrs, or rust found on them.
q
q Coat the rotating parts and sliding parts with engine oil.
q Coat the surfaces of the press-fitting parts with molybdenum disulfide lubricant (LM-P).
After installing the snap ring, check that the snap ring is settled in the ring groove completely.
q
q When connecting wiring harness connectors, clean the connectors to remove oil, dirt, or water, then
connect them securely.
q Use the eye bolts with no fatigue and deformation and screw them in securely. Match the directions of
the eyes and the hook.
q When installing split flanges, tighten the bolts uniformly and alternately to prevent excessive tightening
on one side.
a When the hydraulic cylinder is used for the first time after reassembly of the hydraulic equipment such
as the hydraulic cylinder, pump, etc. and piping after removing them for repair, be sure to perform air
bleeding of the hydraulic circuit according to the following procedure.
1. Start and run the engine at low idle.
2. Repeat the operation to extend and retract each cylinder of the work equipment to approximately
100 mm before the stroke end four to five times.
