General Information
GENERAL PRECAUTIONS FOR
SEPARATION AND REINSTALLATION
Before Operation
Always be safety-conscious in selecting clothes to wear
and suitable tools to use.
Before disassembly, be sure that you familiarize yourself
with the assembled condition for sub-sequent reference in
assembly.
Keep parts and tools in proper order during operations.
When servicing electrically live parts, be sure to
disconnect the negative battery terminal.
To prevent oil or water leaks, use the liquid gasket as
required.
When reassembling disassembled parts, discard used
gaskets, O-rings, or oil seals and install new ones.
When lifting up only the front or rear part of the tractor, be
sure to wedge the grounded wheels.
When the tractor is jacked up, be sure to support the
entire tractor with something like a stand. Lifting it up with
a jack only is a dangerously unstable procedure.
Precautions to be Followed when
Installing Common Parts
Roller or Ball Bearings
When a bearing is fitted in by the outer race, use an
installer which is specially designed to push only the outer
race and vice versa.
The installer must be designed to install the bearing on
the shaft in a parallel position.
When installing a bearing which appears the same on
both sides, install it so that the face which has the
identification number faces in a direction for easy visual
identification. All the bearings which are to be installed in
the transmission case must be placed so that their
identification number faces outward.
If a shaft or a hole where a bearing is to be installed has a
stopper, the bearing must be pushed in completely until it
is seated against the stopper.
Installed bearings must turn smoothly.
Oil Seals
Oil seal installer must be designed so as not to deform the
oil seals.
During installation, be careful not to damage the lips, and
assure that it is pushed in parallel to the shaft or hole.
When oil seals are installed, there must be no turnover of
the lips nor dislocation of the springs.
When a multi-lip seal is installed, the grooves between
lips must be filled with grease, not adhesive.
Use a lithium-based grease.
There must be no oil or water leaks through the installed
soil seals.
