1. PRECAUTIONS FOR DISASSEMBLY AND REASSEMBLY
When removing, installing, disassembling or reassembling the unit, observe the general
precautions described below.
1) Precautions for removal work
Coolant that contains antifreeze should be treated as a chemical, and must not be drained
carelessly on the ground.
To prevent dust from getting into disconnected hoses and tubes, cover them with a plug or similar
means.
When draining oil, use a receptacle with sufficient capacity to receive it.
Before proceeding with the work, look for matchmarks that show the installation location. For
reassembly, place matchmarks in the required locations to prevent errors. Then remove.
When disconnecting wiring connectors, hold the connector components so that unreasonable force
is not applied to the wires.
Label wires and hoses to ensure correct installation location.
Confirm the number and thickness of shims prior to storage.
When lifting parts, use lifting equipment of sufficient capacity.
When separating parts by using pull bolts, tighten the bolts alternately.
Before removing a unit, clean its surrounding area. Then after removal, cover it to prevent dust
and other substances from getting in.
Before removing piping for hydraulic oil or coolant, or removing related parts, satisfactorily release
internal pressure.
2) Precautions for installation work
Tighten bolts and nuts (sleeve nuts) to the specified torque (screw tightening torque table).
When installing hoses, do not twist them or allow them to interfere with other parts.
Replace gaskets, O-rings, split cotter pins, and lock plates with new parts.
Properly bend split cotter pins and lock plates.
When applying an adhesive, first clean and remove oil/grease from the surfaces properly. Then
apply two or three drops to the threaded areas.
When applying a liquid gasket, first clean and remove oil/grease from the application surface
properly, and confirm that the surface is free of dust and damage. Then apply the product evenly.
Clean parts well. Repair scratches, dents, burrs, rust, etc.
Apply gear oil to rotating and sliding components.
Apply grease to the surfaces of press-fit parts.
After installing snap rings, confirm that they are properly seated in the grooves.
Connect wiring connectors securely after cleaning off adhering oil, dust and water.
Use lifting bolts that are not fatigued or deformed. Screw them in fully.
When tightening a split flange, tighten screws alternately to prevent uneven tightening.
Before installing hydraulic parts, confirm that they are free of damage and dust, etc.
