1.5 General precautions for disassembly and installation
1.5.1 Precautions for disassembling and installing
Before Operation
Always be safety conscious in selecting clothes to wear and correct tools to use.
Before disassembly, make sure that you become familiar with the assembled condition to assist in
assembly.
Keep parts, and tools in the correct order during operations.
When assembling disassembled parts, discard used gasket, O-rings, or oil seals and install new ones.
When lifting, tip only the front, or rear part of the tractor, make sure to wedge the grounded wheels.
When the tractor is jacked up, make sure to support the full tractor with a stand. Do not raise the tractor
with only a jack. This is a dangerously unstable procedure.
1.5.2 Precautions when installing according to standards parts
Bearings
Use an installer when installing a bearing in a housing by the outer race. The installer 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 looks the same on both sides, install the face with the identification
number visible. Install all bearings in the transmission case with their identification number pointing
outward.
A bearing installed in a shaft or a hole with an inner seat, must be pushed in fully until seated.
Bearings must turn smoothly.
Oil seals
A oil seal installer must not deform the oil seals.
During installation, be careful not to damage the lips. Make sure that the bearing is pushed in parallel to the
shaft or hole.
Installed oil seals must have no turnover of the lips and no dislocation of the springs.
When a multi-lip seal is installed, the grooves between the lips must be filled with grease.
Use a lithium-based grease.
There must not be any oil or water leaks around the new seals.
O-rings
Coat O-rings with grease before installing.
Installed O-rings must not have any tension or twist.
Installed O-rings must keep correct tightness.
