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.
• Make sure that you try to operate the engine after you repair or
assemble it. Do not try to give a heavy load immediately, if not,
you can cause serious damage to the engine.
