2. GENERAL PRECAUTIONS
• When you disassemble, carefully put the parts in a clean area
to make it easy to find the parts. You must install the screws,
bolts and nuts in their initial position to prevent the reassembly
errors.
• When it is necessary to use special tools, use KUBOTA special
tools. Refer to the drawings when you make special tools that
you do not use frequently.
• Before you disassemble or repair machine, make sure that you
always disconnect the ground cable from the battery first.
• Remove oil and dirt from parts before you measure.
• Use only KUBOTA genuine parts for replacement to keep the
machine performance and to make sure of safety.
• You must replace the gaskets and O-rings when you assemble
again. Apply grease (1) to new O-rings or oil seals before you
assemble.
• When you assemble the external or internal snap rings, make
sure that the sharp edge (3) faces against the direction from
which force (2) is applied.
• When inserting spring pins, their splits must face the direction
from which a force is applied. See the figure left side.
• To prevent damage to the hydraulic system, use only specified
fluid or equivalent.
• Clean the parts before you measure them.
• Tighten the nipples to the specified torque. Too much torque
can cause damage to the hydraulic units or the nipples. Not
sufficient torque can cause oil leakage.
• When you use a new hose or pipe, tighten the nuts to the
specified torque. Then loosen (approx. by 45 °) and let them be
stable before you tighten to the specified torque (This is not
applied to the parts with seal tape).
• When you remove the two ends of a pipe, remove the lower end
first.
• Use two pliers in removal and installation. One to hold the stable
side, and the other to turn the side you remove to prevent twists.
• Make sure that the sleeves of flared connectors and taper s of
hoses are free of dust and scratches.
• After you tighten the nipples, clean the joint and apply the
maximum operation pressure 2 to 3 times to examine oil
leakage.
