GENERAL PRECAUTIONS FOR
SEPARATION AND RE-INSTALLATION
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 subsequent reference in
reassembly.
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.
When replacing parts, use authorized, genuine AGCO
parts only. AGCO assumes no responsibility for
accidents, operating problems or damage caused by the
use of imitation parts. Also, the use of unauthorized parts
will result in relatively poor machine performance.
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 should 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 should be pushed in completely until
it is seated against the stopper.
Installed bearings should turn smoothly.
Oil Seals
Oil seal installer should 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 should be neither
turnover of the lips nor dislocation of the springs.
When a multi-lip seal is installed, the grooves between
lips should be filled with grease, not adhesive.
Use a lithium-based grease.
There should be no oil or water leaks through the installed
oil seals.
O-Rings
O-rings should be coated with grease before installing.
Installed O-rings should have no slack or twist.
Installed O-rings should maintain proper air tightness.
