• 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 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.
• To prevent damage to the hydraulic system, use
specified fluid or equivalent.
• Clean the parts before you measure them.
• Tighten the fittings to the specified torque. Too
much torque can cause damage to the hydraulic
units or the fittings. 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
tapers of hoses are free of dust and scratches.
• After you tighten the fittings, clean the joint and
apply the maximum operation pressure 2 to 3 times
to check oil leakage.
